* $wgUseInstantCommons now hotlinks Commons images by default instead of
 
  downloading originals and thumbnailing them locally. This allows wikis to save
 
  on CPU and bandwidth while reducing time to first byte for pages, even without
 
  a thumbnail handler. See $wgForeignFileRepos documentation for tweaks.
 
* (T27397) WebP is enabled by default as an uploadable filetype.
 
* (T48998) $wgArticlePath must now be either a full url, or start with a "/".
 
* $wgRateLimitLog was removed; use $wgDebugLogGroups['ratelimit'] instead.
 
* Deprecated API formats dbg, txt, and yaml have been removed.
 
* CLDRPluralRule* classes have been replaced with
 
  wikimedia/cldr-plural-rule-parser.
 
* Removed $wgProfilePerHost, $wgUDPProfilerHost, $wgUDPProfilerPort,
 
  $wgUDPProfilerFormatString, $wgStatsMethod, $wgAggregateStatsID,
 
  $wgStatsFormatString, and $wgProfileCallTree (deprecated since 1.20).
 
* For proper operation of LocalIdLookup with shared user tables, ensure that
 
  $wgSharedDB and $wgSharedTables are properly set even on the "central" wiki
 
  that all others are sharing from and that $wgLocalDatabases is set to the
 
  full list of sharing wikis on all those wikis.
 
* Massive overhaul to session handling:
 
** $wgSessionsInObjectCache is no longer supported and must be true, due to
 
  MediaWiki\Session\SessionManager. $wgSessionHandler is similarly no longer
 
  used.
 
** ObjectCacheSessionHandler is removed, replaced with
 
  MediaWiki\Session\PhpSessionHandler.
 
** PHP session handling in general ($_SESSION, session_id(), and so on) is
 
  deprecated. Use MediaWiki\Session\SessionManager instead. A new config
 
  variable, $wgPHPSessionHandling, is available to cause use of $_SESSION to
 
  issue a deprecation warning or to cause most PHP session handling to throw
 
  exceptions.
 
** Deprecated UserSetCookies hook. Session-handling extensions should generally
 
  be creating a custom subclass of CookieSessionProvider. Other extensions
 
  messing with cookies can no longer count on user data being saved in cookies
 
  versus other methods.
 
** Deprecated UserLoadFromSession hook, extensions should create a
 
  MediaWiki\Session\SessionProvider.
 
** The User cannot be loaded from session until after Setup.php completes.
 
  Attempts to do so will be ignored and the User will remain unloaded.
 
** CSRF tokens may be fetched from the MediaWiki\Session\Session, which uses
 
  the MediaWiki\Session\Token class.
 
* MediaWiki will now auto-create users as necessary, removing the need for
 
   extensions to do so. An 'autocreateaccount' right is added to allow
 
  auto-creation when 'createaccount' is not granted to all users.
 
* Deprecated AuthPluginAutoCreate hook in favor of LocalUserCreated.
 
* Most cookie-handling methods in User are deprecated.
 
* $wgAllowAsyncCopyUploads and $CopyUploadAsyncTimeout were removed. This was an
 
  experimental feature that has never worked.
 
* Login and createaccount tokens now vary by timestamp.
 
* LoginForm::getLoginToken() and LoginForm::getCreateaccountToken()
 
  return a MediaWiki\Session\Token, and tokens must be checked using that
 
  class's methods.
 
* $wgEnotifUseJobQ was removed and the job queue is always used.
 
* The functionality of the ApiSandbox extension has been merged into core. The
 
   extension should no longer be used.
 
* $wgPreloadJavaScriptMwUtil was removed (deprecated in 1.26).
 
  Extensions, skins, gadgets and scripts that use the mediawiki.util module must
 
  express a dependency on it.
 
* $wgIncludeLegacyJavaScript, deprecated in MediaWiki 1.26, now defaults false.
 
   Extensions, skins, gadgets and scripts that need the mediawiki.legacy.wikibits
 
  module should express a dependency on it.
 
* Removed configuration option $wgCopyrightIcon (deprecated since 1.18). Use
 
  $wgFooterIcons['copyright']['copyright'] instead.
 
* If the openssl and mcrypt PHP extensions are both unavailable, secure
 
  session storage (used for login) will raise an exception. This exception may
 
   be bypassed by setting $wgSessionInsecureSecrets = true.
 
* Massive overhaul to authentication:
 
** AuthPlugin and AuthPluginUser are deprecated.
 
** LoginForm and associated templates are deprecated. Extensions which called
 
  static LoginForm methods should be converted into authentication providers.
 
** The following hooks are deprecated:
 
*** AbortAutoAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
 
*** AbortLogin (create a MediaWiki\Auth\PreAuthenticationProvider instead)
 
*** AbortNewAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
 
*** AddNewAccount (use LocalUserCreated instead)
 
*** AuthPluginSetup (create a MediaWiki\Auth\PrimaryAuthenticationProvider instead)
 
*** ChangePasswordForm (use AuthChangeFormFields instead, or security levels)
 
*** LoginUserMigrated (create a MediaWiki\Auth\PreAuthenticationProvider instead)
 
*** UserCreateForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
 
*** UserLoginForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
 
** The following hooks are removed:
 
*** AbortChangePassword
 
*** LoginPasswordResetMessage
 
*** PrefsPasswordAudit
 
** The UserLoginComplete hook will no longer be called for all logins, only for
 
  those via the web UI. Use UserLoggedIn if you need to do something on all
 
  logins.
 
** $wgRequirePasswordforEmailChange is removed.

* Whitelisted the following HTML attributes for all elements in wikitext:
 
  aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
 
* Removed "presentation" restriction on the HTML role attribute in wikitext.
 
  All values are now allowed for the role attribute.
 
* $wgContentHandlers now also supports callbacks to create an instance of the
 
  appropriate ContentHandler subclass.
 
* Added $wgAuthenticationTokenVersion, which if non-null prevents the
 
  user_token database field from being exposed in cookies. Setting this would
 
  be a good idea, but will log out all current sessions.
 
* $wgEventRelayerConfig was added, for managing PubSub event relay configuration,
 
   specifically for reliable CDN url purges.
 
* Requests have unique IDs, equal to the UNIQUE_ID environment variable (when
 
  MediaWiki is behind Apache+mod_unique_id or something similar) or a randomly-
 
  generated 24-character string. This request ID is used to annotate log records
 
   and error messages. It is available client-side via mw.config.get( 'wgRequestId' ).
 
  The request ID supplants exception IDs. Accordingly, MWExceptionHandler::getLogId()
 
   is deprecated.
 
* (T33313) Add a preference for watching uploads by default, also applies
 
  to API-based upload tools.
 
* $wgJpegPixelFormat was added to override chroma subsampling for JPEG image
 
   thumbnails created via ImageMagick. Defaults to 'yuv420', providing bandwidth
 
  savings versus the previous behavior on many files.
 
* MediaWiki\Auth infrastructure (called "AuthManager") allows for more flexible
 
   configuration of multiple authentication pieces that was possible with
 
  AuthPlugin. For example, it's now easy to plug in second-factor
 
   authentication, or add additional checks to the login process, or to support
 
  multiple login methods at once, or to support non-password-based login methods.
 
** Providers are configured via the global setting $wgAuthManagerConfig.
 
** A global, $wgDisableAuthManager, is temporarily available to disable
 
  AuthManager until extensions are ready to support it.
 
** New hook, AuthChangeFormFields, to adjust the form fields on
 
  AuthManager-related special pages.
 
** New hook, AuthManagerLoginAuthenticateAudit, for additional logging of
 
  AuthManager-related authentication requests.
 
** New hook, ChangeAuthenticationDataAudit, for additional logging of
 
  AuthManager-related authentication data changes.
 
** New hook, SecuritySensitiveOperationStatus, to work with the new mechanism
 
  for requiring a recent login before taking security-sensitive operations

=== Compatibility ===
 
 
 
MediaWiki 1.27 requires PHP 5.5.9 or later. There is experimental support for
 
HHVM 3.6.5 or later.
 
 
 
MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 
support for them is somewhat less mature. There is experimental support for
 
Oracle and Microsoft SQL Server.
 
  
The supported versions are:

 +
  * ::clearCookie()
 +
  * ::setExtendedLoginCookie()

 +
* The global function wfBaseConvert, deprecated in 1.27, has been removed. Use
 +
  Wikimedia\base_convert() directly.
 +
* Calling Database::begin() explicitly during an implicit transaction or when
 +

* As part of work to modernise user-generated content clean-up, a config option
 +
  and some methods related to HTML validity were removed without deprecation.
 +
  The public methods MWTidy::checkErrors() and the path through which it was
 +
  called, TidyDriverBase::validate(), are removed, as are the testing methods
 +
  MediaWikiTestCase::assertValidHtmlSnippet() and ::assertValidHtmlDocument().

+
* The global function wfBCP47 is deprecated in favour of LanguageCode::bcp47.
* Microsoft SQL Server 2005 (9.00.1399)
+
* The global function wfCountDown is now deprecated in favor of
 +
  Maintenance::countDown.
 +
* Several methods for returning lists of fields to select from the database
 +
  have been deprecated in favor of similar methods that also return the tables
 +
  to select from and the join conditions for those tables.
 +
  * Block::selectFields() → Block::getQueryInfo()
 +
  * RecentChange::selectFields() → RecentChange::getQueryInfo()
 +
  * ArchivedFile::selectFields() → ArchivedFile::getQueryInfo()
 +
  * LocalFile::selectFields() → LocalFile::getQueryInfo()
 +
  * LocalFile::getCacheFields() with a prefix no longer works

  * Revision::selectUserFields() → Revision::getQueryInfo( [ 'user' ] )
 +
  * Revision::pageJoinCond() → Revision::getQueryInfo( [ 'page' ] )

 +
* Revision::setUserIdAndName() was deprecated.
 +

 +
  should be used instead.
 +
* DifferenceEngine::getDiffBodyCacheKey() is deprecated. Subclasses should
 +
  override DifferenceEngine::getDiffBodyCacheKeyParams() instead.
 +
* Use of Maintenance::error( $err, $die ) to exit script was deprecated. Use
 +
  Maintenance::fatalError() instead.
 +
* Passing a ParserOptions object to OutputPage::parserOptions() is deprecated.
 +
* The RevisionInsertComplete hook is now deprecated; use instead the hook
 +
  RevisionRecordInserted. RevisionInsertComplete is still called, but the second
 +
  and third parameter will always be null. Hard deprecation is scheduled for 1.32.
 +
* The following methods that get and set ParserOutput state are deprecated.
 +

 +
    are also deprecated.
 +
* License::getLicenses has been deprecated; use License::getLines instead.
 +
* QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
 +
  Setting template variables by reference allowed violating the principle of
 +
  data being immutable once added to the skin template. In practice, this method
 +
  was not being used for that. Rather, setRef() existed as memory optimisation
 +
  for PHP 4.
 +
* QuickTemplate::setTranslator() and MediaWikiI18N::set() were deprecated in
 +
  favour of Skin::msg() parameters.
 +
* MediaWikiI18N::translate() was deprecated in favour of Skin::msg() or
 +

 +
  \Wikimedia\ObjectFactory from the wikimedia/object-factory library should be
 +
  used instead.
 +
* CommentStore::newKey is deprecated. Instead, get an instance from
 +
  MediaWikiServices.
 +
* The following CommentStore methods have had their signatures changed to
 +
  introduce a $key parameter, usage of the methods on instances retrieved from
 +
  CommentStore::newKey will remain unchanged but deprecated:
 +
  * CommentStore::getFields
 +
  * CommentStore::getJoin
 +
  * CommentStore::getComment
 +
  * CommentStore::getCommentLegacy
 +
  * CommentStore::insert
 +
  * CommentStore::insertWithTemplate

* The following methods in Title have been renamed, and the old ones are
 +
  deprecated:
 +
  * Title::getSkinFromCssJsSubpage – use ::getSkinFromConfigSubpage
 +
  * Title::isCssOrJsPage – use ::isSiteConfigPage
 +
  * Title::isCssJsSubpage – use ::isUserConfigPage
 +
  * Title::isCssSubpage – use ::isUserCssConfigPage
 +
  * Title::isJsSubpage – use ::isUserJsConfigPage
 +
* The following methods related to caching of half-parsed HTML were deprecated:
 +
  * Parser::serializeHalfParsedText()
 +
  * Parser::unserializeHalfParsedText()
 +
  * Parser::isValidHalfParsedText()
 +
  * StripState::getSubState()
 +
  * StripState::merge()

 +
  used instead.
 +

 +
  MediaWiki\Shell::makeScriptCommand().
 +
* In the future, the hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend'
 +
  will be allowed to provide any HTMLForm object rather than PreferencesForm.
  
=== Upgrading ===
+
=== Other changes in 1.31 ===
 +
* Browser support for Internet Explorer 10 was lowered from Grade A to Grade C.
 +
* Browser support for Opera 12 and older was dropped entirely. Opera 15+
 +
  continues at Grade A.
 +
* Multi-content-revision capability was introduced into the storage layer. See
 +
  <https://mediawiki.org/wiki/Requests_for_comment/Multi-Content_Revisions>.
 +
* The "free" CSS class is now only applied to unbracketed URLs in wikitext.
 +
  Links written using square brackets will get the class "text" not "free".
 +
* RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
 +
  wikitext table captions, wikitext table headings, wikitext table cells. HTML
 +
  headings, HTML list items, HTML table captions, HTML table headings, HTML
 +
  table cells will not have this trimming behavior.
  
1.27 has several database changes since 1.26, and will not work without schema

updates. Note that due to changes to some very large tables like the revision
 
table, the schema update may take quite long (minutes on a medium sized site,
 
many hours on a large site).

If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
+
== MediaWiki 1.30 ==
1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 
with MediaWiki 1.21.

See the file UPGRADE for more detailed upgrade instructions.
+
=== MySQL version requirement in 1.30 ===
 +
As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
 +
section).
  
For notes on 1.26.x and older releases, see HISTORY.
+
=== Configuration changes in 1.30 ===
 +
* The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
 +
  unexpected behavior when code uses locale-sensitive string comparisons. For
 +
  example, the Scribunto extension considers "bar" < "Foo" in most locales
 +
  since it ignores case.
 +
* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
 +
  documentation of $wgShellLocale for details.
 +
* $wgShellLocale is now applied for all requests. wfInitShellLocale() is
 +
  deprecated and a no-op, as it is no longer needed.
 +
* $wgJobClasses may now specify callback functions as an alternative to plain
 +
  class names. This is intended for extensions that want control over the
 +
  instantiation of their jobs, to allow for proper dependency injection.
 +
* $wgResourceModules may now specify callback functions as an alternative
 +
  to plain class names, using the 'factory' key in the module description
 +
  array. This allows dependency injection to be used for ResourceLoader modules.
 +
* $wgExceptionHooks has been removed.
 +
* (T163562) $wgRangeContributionsCIDRLimit was introduced to control the size
 +
  of IP ranges that can be queried at Special:Contributions.
 +
* (T45547) $wgUsePigLatinVariant added (off by default).
 +
* (T152540) MediaWiki now supports a section ID escaping style that allows to display
 +
  non-Latin characters verbatim on many modern browsers. This is controlled by the
 +
  new configuration setting, $wgFragmentMode.
 +
* $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
 +
  use $wgFragmentMode to migrate off it to a modern alternative.
 +
* $wgExternalInterwikiFragmentMode was introduced to control how fragments in
 +
  sinterwikis going outside of current wiki farm are encoded.
 +
* (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
 +
  This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
 +
  auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
 +
  requested through the configuration parameter $wgDBservers.
 +
* $wgOOUIEditPage was removed, as it is now the default. This was documented as a
 +
  temporary variable during the migration period.
  
 +
=== New features in 1.30 ===
 +
* (T37247) Output from Parser::parse() will now be wrapped in a div with
 +
  class="mw-parser-output" by default. This may be changed or disabled using
 +
  ParserOptions::setWrapOutputClass().
 +
* (T163562) Added ability to search for contributions within an IP ranges
 +
  at Special:Contributions.
 +
* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
 +
  specific tags to be added by users.
 +
* Added a 'ParserOptionsRegister' hook to allow extensions to register
 +
  additional parser options.
 +
* (T45547) Included Pig Latin, a language game in English, as a
 +
  LanguageConverter variant.  This allows English-speaking developers
 +
  to develop and test LanguageConverter more easily.  Pig Latin can be
 +
  enabled by setting $wgUsePigLatinVariant to true.
 +
* Added RecentChangesPurgeRows hook to allow extensions to purge data that
 +
  depends on the recentchanges table.
 +
* Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
 +
* (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
 +
  'watchlistunwatchlinks' preference option is enabled). With JavaScript
 +
  enabled, these links toggle so the user can also re-watch pages that have
 +
  just been unwatched.
 +
* Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
 +
  MediaHandlerFactory for parser tests.
 +
* Edit summaries, block reasons, and other "comments" are now stored in a
 +
  separate database table. Use the CommentFormatter class to access them.
 +
** This is currently gated by $wgCommentTableSchemaMigrationStage. Most wikis
 +
  can set this to MIGRATION_NEW and run maintenance/migrateComments.php as
 +
  soon as any necessary extensions are updated.
 +
* (T138166) Added ability for users to prohibit other users from sending them
 +
  emails with Special:Emailuser. Can be enabled by setting
 +
  $wgEnableUserEmailBlacklist to true.
 +
* (T67297) $wgBrowserBlacklist is deprecated, and changing it will have no effect.
 +
  Instead, users using browsers that do not support Unicode will be unable to edit
 +
  and should upgrade to a modern browser instead.

=== External library changes in 1.30 ===
  
== MediaWiki 1.26.2 ==
 
 
This is a maintenance release of the MediaWiki 1.26 branch.
 
 
=== Changes since 1.26.1 ===
 
* (T121892) Fix fatal error on some Special pages, introduced in 1.26.1.
 
 
== MediaWiki 1.26.1 ==
 
 
This is a maintenance release of the MediaWiki 1.26 branch.
 
 
=== Changes since 1.26.0 ===
 
* (T117899) SECURITY: $wgArticlePath can no longer be set to relative paths
 
  that do not begin with a slash. This enabled trivial XSS attacks.
 
  Configuration values such as "http://my.wiki.com/wiki/$1" are fine, as are
 
  "/wiki/$1". A value such as "$1" or "wiki/$1" is not and will now throw an
 
  error.
 
* (T119309) SECURITY: Use hash_compare() for edit token comparison
 
* (T118032) SECURITY: Don't allow cURL to interpret POST parameters starting
 
  with '@' as file uploads
 
* (T115522) SECURITY: Passwords generated by User::randomPassword() can no
 
  longer be shorter than $wgMinimalPasswordLength
 
* (T97897) SECURITY: Improve IP parsing and trimming. Previous behavior could
 
  result in improper blocks being issued
 
* (T109724) SECURITY: Special:MyPage, Special:MyTalk, Special:MyContributions
 
  and related pages no longer use HTTP redirects and are now redirected by
 
  MediaWiki
 
* Fixed ConfigException in ExpandTemplates due to AlwaysUseTidy.
 
* Fixed stray literal \n in Special:Search.
 
* Fix issue that breaks HHVM Repo Authorative mode.
 
* (T120267) Work around APCu memory corruption bug
 
 
== MediaWiki 1.26.0 ==
 
 
=== Configuration changes in 1.26 ===
 
* $wgPasswordResetRoutes['email'] = true by default.
 
* $wgEnableParserCache was deprecated, set $wgParserCacheType to CACHE_NONE
 
  instead if you want to disable the parser cache.
 
* New-style continuation is now the default for API action=continue. Clients may
 
  use the 'rawcontinue' parameter to receive raw query-continue data, but the
 
  new style is encouraged as it's harder to implement incorrectly.
 
* Deprecated API formats dump and wddx have been completely removed.
 
* (T7645) The "Signature" button on the edit toolbar is now hidden by default
 
  in non-talk namespaces. A new configuration variable,
 
  $wgExtraSignatureNamespaces, controls in which subject (non-talk) namespaces
 
  the "Signature" button on the edit toolbar will be displayed.
 
* $wgResourceLoaderUseESI was deprecated and removed. This was an experimental
 
  feature that was never enabled by default.
 
* $wgResourceLoaderExperimentalAsyncLoading was deprecated and removed.
 
  This experimental feature was never enabled by default and is obsolete as of
 
  MediaWiki 1.26, in where ResourceLoader became fully asynchronous.
 
* $wgMasterWaitTimeout was removed (deprecated in 1.24).
 
* Fields in ParserOptions are now private. Use the accessors instead.
 
* Custom LESS functions (defined via $wgResourceLoaderLESSFunctions or
 
  in extension.json) have been removed, after being deprecated in 1.24.
 
* $wgAlwaysUseTidy has been removed.
 
* ResetSessionID hook has been removed. Nothing seems to use it.
 
* Certain AuthPlugin methods are deprecated in favor of new hooks:
 
** AuthPlugin::initUser() is replaced by LocalUserCreated.
 
** AuthPlugin::updateUser() is replaced by UserLoggedIn.
 
** AuthPlugin::updateExternalDB() is replaced by the existing UserSaveSettings.
 
** AuthPlugin::updateExternalDBGroups() is replaced by UserGroupsChanged.
 
** AuthPluginUser::isHidden() is replaced by UserIsHidden.
 
** AuthPluginUser::isLocked() is replaced by UserIsLocked.
 
* The UserRights hook is deprecated in favor of the new UserGroupsChanged hook.
 
* AuthPlugin::initUser() and AuthPlugin::updateUser() should no longer replace
 
  the passed User object.
 
* $wgBlockAllowsUTEdit is now set to true by default. This allows
 
  blocked users to edit their talk pages unless explicitly disabled
 
  when they are being blocked.
 
 
=== New features in 1.26 ===
 
* (T51506) Now action=info gives estimates of actual watchers for a page.
 
  See $wgRCMaxAge, $wgWatchersMaxAge and $wgUnwatchedPageSecret
 
  to learn how to configure if needed.
 
* Change tags can now be hidden in the interface by disabling the associated
 
  "tag-<id>" interface message.
 
* ':' (colon) is now invalid in usernames for new accounts. Existing accounts
 
  are not affected.
 
* Added a new hook, 'LogException', to log exceptions in nonstandard ways.
 
* Revive the 'SpecialSearchResultsAppend' hook which occurs after the list of
 
  search results are rendered. The initial use case is to append a "give us
 
  feedback" link beneath the search results.
 
* Added a new hook, 'RejectParserCacheValue', which allows extensions to
 
  reject an otherwise-successful parser cache lookup. The intent is to allow
 
  extensions to manage the eviction of archaic HTML output from the cache.
 
* (T68699) The expiration of the UserID and Token login cookies
 
  ($wgExtendedLoginCookieExpiration) can be configured independently of the
 
  expiration of all other cookies ($wgCookieExpiration).
 
* (T50519) Support for generating JPEG/PNG thumbnails from WebP images added
 
  if ImageMagick is used as image scaler ($wgUseImageMagick = true). Uploading
 
  of WebP images still disabled by default. Add $wgFileExtensions[] =
 
  'webp'; to LocalSettings.php to enable uploading of WebP images.
 
* Added new hooks 'EnhancedChangesListModifyLineData' &
 
  'EnhancedChangesListModifyBlockLineData', to modify the data used to build
 
  lines in enhanced recentchanges and watchlist.
 
* Caches that need purging ability now use the WANObjectCache interface.
 
  This corresponds to a new $wgMainWANCache setting, which defaults to using
 
  the $wgMainCacheType settings.
 
* Callers needing fast light-weight data stores use $wgMainStash to select
 
  the store type from $wgObjectCaches. The default is the local database.
 
* Interface message overrides in the MediaWiki namespace will now be cached in
 
  memcached and APC (if available), rather than memcached and local files.
 
* Added a new hook, 'RandomPageQuery', to allow modification of the query used
 
  by Special:Random to select random pages.
 
* $wgTransactionalTimeLimit was added, which controls the request time limit
 
  for potentially slow POST requests that need to be as atomic as possible.
 
* ResourceLoader now loads all scripts asynchronously. The top-queue and
 
  startup modules are no longer synchronously loaded.
 
* 'mediawiki.ui.button' styles are no longer unconditionally loaded on every
 
  page. During the deprecation period, the styles will only be loaded on pages
 
  which contain 'mw-ui-button' in their HTML. Starting in 1.28, the styles will
 
  only be loaded if explicitly required.
 
* If search returns zero results and current search engine has a "did you mean"
 
  suggestion, results for suggestion will be shown. Can be disabled by setting
 
  $wgSearchRunSuggestedQuery to false.
 
* Added several JavaScript libraries for uploading files to MediaWiki
 
  from the client-side. See documentation for mw.Upload and its
 
  subclasses for more information.
 
* Added OOUI dialogs and layout for file upload interfaces. See
 
  documentation for mw.Upload.Dialog, mw.Upload.BookletLayout and its
 
  subclasses for more information.
 
 
=== extension.json changes in 1.26 ===
 
* (T99344) The extension.json schema is now versioned. All extensions
 
  and skins should set a "manifest_version" property corresponding to
 
  the schema version they were written for. The only supported version
 
  currently is "1".
 
* (T102523) The error message if a non-array attribute is set was improved.
 
* (T107646) Configuration settings can now specify how they should be merged,
 
  which is necessary for arrays using integer keys.
 
* (T110389) Adding namespaces through extension.json now actually works
 
* $wgNamespaceProtection can now be set in extension.json.
 
* $wgCapitalLinkOverrides can now be set in extension.json.
 
* (T97186) Extensions using a custom prefix for their configuration settings
 
  can now set a "_prefix" key to override the default of "wg".
 
* (T99084) Extensions can now specify what MediaWiki core versions they
 
  depend upon.
 
* (T105236) The extension.json schema now validates custom classes in
 
  the "ResourceModules" property properly.

=== Other changes in 1.26 ===
+
==== Pig Latin added ====
* ChangeTags::tagDescription() will return false if the interface message
+
* (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
  for the tag is disabled.
+
   for easier variant development and testing. Disabled by default. It can be
* Added PageHistoryPager::doBatchLookups hook.
+
   enabled by setting $wgUsePigLatinVariant to true.
* Added $wikiId parameter to FormatAutocomments hook.
 
* Added ParserCacheSaveComplete to ParserCache
 
* supportsDirectEditing and supportsDirectApiEditing methods added to
 
  ContentHandler, to provide a way for ApiEditPage and EditPage to check
 
  if direct editing of content is allowed. These methods return false,
 
  by default for the ContentHandler base class and true for TextContentHandler
 
  and it's derivative classes (everything in core). For Content types that
 
  do not support direct editing, an alternative mechanism should be provided
 
  for editing, such as action overrides or specific api modules.
 
* mediaWiki.confirmCloseWindow now returns an object of functions, instead of
 
  one function. The callback can't be called directly any more. The callback
 
  function is replaced with confirmCloseWindow.release().
 
* BREAKING CHANGE: Added an optional ResouceLoaderContext parameter to
 
  ResourceLoaderModule::getDependencies(). Extension classes that override that
 
  method should be updated. If they aren't updated, PHP Strict standards
 
  warnings will appear when E_STRICT error reporting is enabled. Note: in the
 
  near future, this parameter will probably become non-optional.
 
* Removed maintenance script deleteImageMemcached.php.
 
* MWFunction::newObj() was removed (deprecated in 1.25).
 
  ObjectFactory::getObjectFromSpec() should be used instead.
 
* The parser will no longer randomize the string it uses to mark the place of
 
  items that were stripped during parsing. It will use a fixed string instead.
 
  This causes the parser to re-use the regular expressions it uses to search
 
  and replace markers rather than generate novel expressions on each parse.
 
  Re-using regular expressions will improve performance on HHVM and the
 
  forthcoming PHP 7. The interfaces changes accompanying this change are:
 
  - Parser::getRandomString() and Parser::uniqPrefix() have been deprecated.
 
   - The $uniq_prefix argument for Parser::extractTagsAndParams() and the
 
    $prefix argument for StripState::_construct() are deprecated and their
 
    value is ignored.
 
* wfSuppressWarnings() and wfRestoreWarnings() were split into a separate library,
 
  mediawiki/at-ease, and are now deprecated. Callers should use
 
  MediaWiki\suppressWarnings() and MediaWiki\restoreWarnings() directly.
 
* The Block class constructor now takes an associative array of parameters
 
  instead of many optional positional arguments. Calling the constructor the old
 
  way will issue a deprecation warning.
 
* The jquery.mwExtension module was deprecated.
 
* $wgSpecialPageGroups was removed (deprecated in 1.21).
 
* SpecialPageFactory::setGroup was removed (deprecated in 1.21).
 
* SpecialPageFactory::getGroup was removed (deprecated in 1.21).
 
* DatabaseBase::ignoreErrors() is now protected.
 
* BREAKING CHANGE: mediawiki.legacy.ajax has been removed, following
 
  a lengthy deprecation period.
 
* The ScopedPHPTimeout class was removed.
 
* Removed maintenance script fixSlaveDesync.php.
 
* Watchlist tokens, SpecialResetTokens, and User::getTokenFromOption()
 
  are deprecated. Applications using those can work via the OAuth
 
   extension instead. New tokens types should not be added.
 
* DatabaseBase::errorCount() was removed (unused).
 
* $wgDeferredUpdateList was removed.
 
* DeferredUpdates::addHTMLCacheUpdate() was removed.
 
  
= MediaWiki 1.25 =
+
=== Other changes in 1.30 ===
 +
* The use of an associative array for $wgProxyList, where the IP address is in
 +
  the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 +
  Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 +
* mw.user.bucket (deprecated in 1.23) was removed.
 +
* LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 +
  deprecated. There are no known callers.
 +
* File::getStreamHeaders() was deprecated.
 +
* MediaHandler::getStreamHeaders() was deprecated.
 +
* Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 +
  used instead.
 +
* MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 +
  should be used instead.
 +
* The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 +
* The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 +
  deprecated in 1.24) were removed.
 +
* wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 +
  BagOStuff::makeGlobalKey() should be used instead.
 +
* (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 +
  As a result of the new uniform handling, '-{' may need to be escaped
 +
  (for example, as '-<nowiki/>{') where it occurs inside template arguments
 +
  or wikilinks.
 +
* (T163966) Page moves are now counted as edits for the purposes of
 +
  autopromotion, i.e., they increment the user_editcount field in the database.
 +
* Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 +
  manipulating Special:Log and Special:NewPages lines.
 +
* The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 +
  PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 +
  hooks have an additional parameter, for manipulating HTML data attributes of
 +
  RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 +
  $data['attribs'] subarray.
 +
* (T130632) The OutputPage::enableTOC() method was removed.
 +
* WikiPage::getParserOutput() will now throw an exception if passed
 +
  ParserOptions that would pollute the parser cache. Callers should use
 +
  WikiPage::makeParserOptions() to create the ParserOptions object and only
 +
  change options that affect the parser cache key.
 +
* Article::viewRedirect() is deprecated.
 +
* IP::isValidBlock() was deprecated. Use the equivalent IP::isValidRange().
 +
* DeprecatedGlobal no longer supports passing in a direct value, it requires a
 +
  callable factory function or a class name.
 +
* The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 +
  are all deprecated. The main ParserCache instance should be obtained from
 +
  MediaWikiServices instead. Access to the underlying BagOStuff is possible
 +
  through the new ParserCache::getCacheStorage() method.
 +
* .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 +
* Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
 +
  escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 +
* Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
 +
  Sanitizer functions or, if possible, Title::getFragmentForURL().
 +
* Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
 +
  nothing and is deprecated.
 +
* mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
 +
  escapeIdForLink().
 +
* MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
 +
* WikiImporter now requires the second parameter to be an instance of the Config,
 +
  class. Prior to that, the Config parameter was optional (a behavior deprecated in
 +
  1.25).
 +
* Removed 'jquery.mwExtension' module. (deprecated since 1.26)
 +
* mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
 +
  any more.
 +
* CdbReader, CdbWriter, CdbException classes (deprecated in 1.25) were removed.
 +
  The namespaced classes in the Cdb namespace should be used instead.
 +
* IPSet class (deprecated in 1.26) was removed. The namespaced IPSet\IPSet
 +
  should be used instead.
 +
* RunningStat class (deprecated in 1.27) was removed. The namespaced
 +
  RunningStat\RunningStat should be used instead.
 +
* MWMemcached and MemCachedClientforWiki classes (deprecated in 1.27) were removed.
 +
  The MemcachedClient class should be used instead.
 +
* EditPage underwent some refactoring and deprecations:
 +
  * EditPage::isOouiEnabled() is deprecated and will always return true.
 +
  * EditPage::getSummaryInput() and ::getSummaryInputOOUI() are deprecated. Please
 +
    use ::getSummaryInputWidget() instead.
 +
  * EditPage::getCheckboxes() and ::getCheckboxesOOUI() are deprecated. Please
 +
    use ::getCheckboxesWidget() instead.
 +
  * Creating an EditPage instance without calling EditPage::setContextTitle() should
 +
    be avoided and will be deprecated in a future release.
 +
  * EditPage::safeUnicodeInput() and ::safeUnicodeOutput() are deprecated and no-ops.
 +
  * EditPage::$isCssJsSubpage, ::$isCssSubpage, and ::$isJsSubpage are deprecated. The
 +
    corresponding methods from Title should be used instead.
 +
  * EditPage::$isWrongCaseCssJsPage is deprecated. There is no replacement.
 +
  * EditPage::$mArticle and ::$mTitle are deprecated for public usage. The getters
 +
    ::getArticle() and ::getTitle() should be used instead.
 +
  * Trying to control or fake EditPage context by overriding $wgUser, $wgRequest, $wgOut,
 +
    and $wgLang is no longer supported and won't work. The IContextSource returned from
 +
    EditPage::getContext() must be modified instead.
 +
* Parser::getRandomString() (deprecated in 1.26) was removed.
 +
* Parser::uniqPrefix() (deprecated in 1.26) was removed.
 +
* Parser::extractTagsAndParams() now only accepts three arguments. The fourth,
 +
  $uniq_prefix was deprecated in 1.26 and has now been removed.
 +
* (T172514) The following tables have had their UNIQUE indexes turned into proper
 +
  PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
 +
  langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
 +
  templatelinks, text, transcache, user_former_groups, user_properties.
 +
* IDatabase::nextSequenceValue() is no longer needed by any database backends
 +
  (formerly it was needed by PostgreSQL and Oracle), and is now deprecated.
 +
* (T146591) The lc_lang_key index on the l10n_cache table has been changed into a
 +
  PRIMARY KEY.
 +
* (T157227) bot_password.bp_user, change_tag.ct_log_id, change_tag.ct_rev_id,

 +
* wfUsePHP() is deprecated.
 +
* wfFixSessionID() was removed.
 +
* wfShellExec() and related functions are deprecated, use Shell::command(). This also
 +
  slightly changes the behavior of how execution time limits are calculated when only
 +
  some of defaults are overridden per-call. When in doubt, always override both wall
 +
  clock and CPU time.
 +
* (T138166) SpecialEmailUser::getTarget() now requires a second argument, the sending

== MediaWiki 1.25.2 ==
+
== MediaWiki 1.29 ==
  
This is a security and maintenance release of the MediaWiki 1.25 branch.
+
=== Configuration changes in 1.29 ===
 +
* Default cookie expiration time has been reduced to 30 days. Login cookie
 +
  expiration time is kept at 180 days.
 +
* A new configuration variable has been added: $wgCookieSetOnAutoblock. This
 +
  determines whether to set a cookie when a user is autoblocked. Doing so means
 +
  that a blocked user, even after logging out and moving to a new IP address,
 +
  will still be blocked.
 +
* The resetpassword right and associated password reset capture feature has
 +
  been removed.
 +
* The $error parameter to the EmailUser hook should be set to a Status object
 +
  or boolean false. This should be compatible with at least MediaWiki 1.23 if
 +
  not earlier. Returning a raw HTML string is now deprecated.
 +
* The $message parameter to the ApiCheckCanExecute hook should be set to an
 +
  ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 +
  code for ApiBase::parseMsg() will no longer work.
 +
* ApiBase::$messageMap is no longer public. Code attempting to access it will
 +
  result in a PHP fatal error.
 +
* $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
 +
  policies.
 +
* Subpages are now enabled by default in the Template namespace. Set
 +
  $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
 +
* $wgRunJobsAsync is now false by default (T142751). This change only affects
 +
  wikis with $wgJobRunRate > 0.
 +
* (T158474) "Unknown user" has been added to $wgReservedUsernames.
 +
* (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
 +
* $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
 +
  added to $wgExtraLanguageCodes instead.
 +
* (T161453) LocalisationCache will no longer use the temporary directory in it's
 +
  fallback chain when trying to work out where to write the cache.
 +
* The user right 'editusercssjs' (deprecated in 1.16) was removed. Use
 +
  'editusercss' and 'edituserjs' in $wgGroupPermissions and elsewhere instead.
  
=== Changes since 1.25.1 ===
+
=== New features in 1.29 ===
 +
* (T5233) A cookie can now be set when a user is autoblocked, to track that user
 +
  if they move to a new IP address. This is disabled by default.
 +
* Added ILocalizedException interface to standardize the use of localized
 +
  exceptions, largely so the API can handle them more sensibly.
 +
* Blocks created automatically by MediaWiki, such as for configured proxies or
 +
  dnsbls, are now indicated as such and use a new i18n message when displayed.
 +
* Added new $wgHTTPImportTimeout setting. Sets timeout for
 +
  downloading the XML dump during a transwiki import in seconds.
 +
* Parser limit report is now available in machine-readable format to JavaScript
 +
  via mw.config.get('wgPageParseReport').
 +
* Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
 +
  from certain IP ranges (e.g. private IPs).
 +
* (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
 +
  of the page being parsed.
 +
* HTML5 form validation attributes will no longer be suppressed. Originally
 +
  browsers had poor support for them, but modern browsers handle them fine.
 +
  This might affect some forms that used them and only worked because the
 +
  attributes were not actually being set.
 +
* Expiry times can now be specified when users are added to user groups.
 +
* Completely new user interface for the RecentChanges page, which
 +
  structures filters into user-friendly groups.  This has corresponding
 +
  changes to how filters are registered by core and extensions.
 +
* The edit form now uses pretty OOjs UI buttons, checkboxes and summary input.
 +
  Because this change can cause problems for extensions and on-wiki
 +
  scripts depending on the exact HTML, the old version is still available
 +
  and can be used by setting $wgOOUIEditPage = false; in LocalSettings.php.
 +
  This will be removed later and OOjs UI will become the only option.
 +
  To make testing easier, users can also force either mode by adding
 +
  &ooui=true or &ooui=false to the action=edit URL.
  
* (T94116) SECURITY: Compare API watchlist token in constant time
+
=== External library changes in 1.29 ===
* (T97391) SECURITY: Escape error message strings in thumb.php
 
* (T106893) SECURITY: Don't leak autoblocked IP addresses on
 
  Special:DeletedContributions
 
* (T102562) Fix InstantCommons parameters to handle the new HTTPS-only
 
  policy of Wikimedia Commons.
 
* (T100767) Setting a configuration setting for skin or extension to
 
  false in LocalSettings.php was not working.
 
* (T100635) API action=opensearch json output no longer breaks when
 
  $wgDebugToolbar is enabled.
 
* (T102522) Using an extension.json or skin.json file which has
 
  a "manifest_version" property for 1.26 compatability will no longer
 
  trigger warnings.
 
* (T86156) Running updateSearchIndex.php will not throw an error as
 
  page_restrictions has been added to the locked table list.
 
* Special:Version would throw notices if using SVN due to an incorrectly
 
  named variable. Add an additional check that an index is defined.

* (T149597) "PasswordPolicy" can be set in extension.json.
** Title::moveTo() was deprecated. Use the MovePage class instead.
 
** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
 
  and MovePage::checkPermissions().
 
* (T18530) Multiple autocomments are now formatted in an edit summary.
 
* (T70361) Autocomments containing "/*" are parsed correctly.
 
* The Special:WhatLinksHere page linked from 'Number of redirects to this page'
 
  on action=info about a file page does not list file links anymore.
 
* (T78637) Search bar is not autofocused unless it is empty so that proper scrolling using arrow keys is possible.
 
* (T50853) Database::makeList() modified to handle 'NULL' separately when building IN clause
 
* (T85192) Captcha position modified in Usercreate template. As a result:
 
** extrafields parameter added to Usercreate.php to insert additional data
 
** 'extend' method added to QuickTemplate to append additional values to any field of data array
 
* (T86974) Several Title methods now load from the database when necessary

=== Action API changes in 1.25 ===
+
=== Languages updated in 1.29 ===
* (T67403) XML tag highlighting is now only performed for formats
 
  "xmlfm" and "wddxfm".
 
* action=paraminfo supports generalized submodules (modules=query+value),
 
  querymodules and formatmodules are deprecated
 
* action=paraminfo no longer outputs descriptions and other help text by
 
  default. If needed, it may be requested using the new 'helpformat' parameter.
 
* action=help has been completely rewritten, and outputs help in HTML
 
  rather than plain text.
 
* Hitting api.php without specifying an action now displays only the help for
 
  the main module, with links to submodule help.
 
* API help is no longer displayed on errors.
 
* 'uselang' is now a recognized API parameter; "uselang=user" may be used to
 
  explicitly select the language from the current user's preferences, and
 
  "uselang=content" may be used to select the wiki's content language.
 
* Default output format for the API is now jsonfm.
 
* Simplified continuation will return a "batchcomplete" property in the result
 
  when a batch of pages is complete.
 
* Pretty-printed HTML output now has nicer formatting and (if available)
 
  better syntax highlighting.
 
* Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
 
  list=alldeletedrevisions.
 
* prop=revisions will gracefully continue when given too many revids or titles,
 
  rather than just ignoring the extras.
 
* prop=revisions will no longer die if rvcontentformat doesn't match a
 
  revision's content model; it will instead warn and omit the content.
 
* If the user has the 'deletedhistory' right, action=query's revids parameter
 
  will now recognize deleted revids.
 
* prop=revisions may be used as a generator, generating revids.
 
* (T68776) format=json results will no longer be corrupted when
 
  $wgMangleFlashPolicy is in effect. format=php results will cleanly return an
 
  error instead of returning invalid serialized data.
 
* Generators may now return data for the generated pages when used with
 
  action=query.
 
* Query page data for generator=search and generator=prefixsearch will now
 
  include an "index" field, which may be used by the client for sorting the
 
  search results.
 
* ApiOpenSearch now supports XML output.
 
* ApiOpenSearch will now output descriptions and URLs as array indexes 2 and 3
 
  in JSON format.
 
* (T76051) list=tags will now continue correctly.
 
* (T76052) list=tags can now indicate whether a tag is defined.
 
* (T75522) list=prefixsearch now supports continuation
 
* (T78737) action=expandtemplates can now return page properties.
 
* (T78690) list=allimages now accepts multiple pipe-separated values
 
  for the 'aimime' parameter.
 
* prop=info with inprop=protections will now return applicable protection types
 
  with the 'restrictiontypes' key.
 
* (T85417) When resolving redirects, ApiPageSet will now add the targets of
 
  interwiki redirects to the list of interwiki titles.
 
* (T85417) When outputting the list of redirect titles, a 'tointerwiki'
 
  property (like the existing 'tofragment' property) will be set.
 
* Added action=managetags to allow for managing the list of
 
  user-modifiable change tags. Actually modifying the tagging of a revision or
 
  log entry is not implemented yet.
 
* list=tags has additional properties to indicate 'active' status and tag
 
  sources.
 
* siprop=libraries was added to ApiQuerySiteInfo to list installed external libraries.
 
* (T88010) Added action=checktoken, to test a CSRF token's validity.
 
* (T88010) Added intestactions to prop=info, to allow querying of
 
  Title::userCan() via the API.
 
* Default type param for query list=watchlist and list=recentchanges has
 
  been changed from all types (e.g. including 'external') to 'edit|new|log'.
 
* Added formatversion to format=json. Still "experimental" as further changes
 
  to the output formatting might still be made.
 
* (T73020) Log event details are now always under a 'params' subkey for
 
  list=logevents, and a 'logparams' subkey for list=watchlist and
 
  list=recentchanges.
 
* Log event details are changing formatting:
 
  * block events now report flags as an array rather than as a comma-separated
 
    list.
 
  * patrol events now report the 'auto' flag as a boolean (absent/empty string
 
    for BC formats) rather than as an integer.
 
  * rights events now report the old and new group lists as arrays rather than
 
    as comma-separated lists.
 
  * merge events use new-style formatting.
 
  * delete/event and delete/revision events use new-style formatting.
 
* The root node and various other nodes will now always be an object in formats
 
  such as json that distinguish between arrays and objects.
 
  * Except for action=opensearch where the spec requires an array.
 
 
 
=== Action API internal changes in 1.25 ===
 
* ApiHelp has been rewritten to support i18n and paginated HTML output.
 
  Most existing modules should continue working without changes, but should do
 
  the following:
 
  * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
 
  * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
 
    to replace getParamDescription(). If necessary, the settings array returned
 
    by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
 
    message.
 
  * Implement getExamplesMessages() to replace getExamples().
 
* Modules with submodules (like action=query) must have their submodules
 
  override ApiBase::getParent() to return the correct parent object.
 
* The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
 
  and will have no effect for modules using i18n messages. Use
 
  'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
 
* Api formatters will no longer be asked to display the help screen on errors.
 
* ApiMain::getCredits() was removed. The credits are available in the
 
  'api-credits' i18n message.
 
* ApiFormatBase has been changed to support i18n and syntax highlighting via
 
  extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
 
  has been removed.
 
* ApiFormatBase now always buffers. Output is done when
 
  ApiFormatBase::closePrinter is called.
 
* Much of the logic in ApiQueryRevisions has been split into ApiQueryRevisionsBase.
 
* The 'revids' parameter supplied by ApiPageSet will now count deleted
 
  revisions as "good" if the user has the 'deletedhistory' right. New methods
 
  ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
 
  provided to access just the live or just the deleted revids.
 
* Added ApiPageSet::setGeneratorData() and ApiPageSet::populateGeneratorData()
 
  to allow generators to include data in the action=query result.
 
* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
 
  used for conditional registration of API modules.
 
* Added ApiBase::lacksSameOriginSecurity() to allow modules to easily check if
 
  the current request was sent with the 'callback' parameter (or any future
 
  method that breaks the same-origin policy).
 
* Profiling methods in ApiBase are deprecated and no longer need to be called.
 
* ApiResult was greatly overhauled. See inline documentation for details.
 
* ApiResult will automatically convert objects to strings or arrays (depending
 
  on whether a __toString() method exists on the object), and will refuse to
 
  add unsupported value types.
 
  * An informal interface, ApiSerializable, exists to override the default
 
    object conversion.
 
* ApiResult/ApiFormatBase "raw mode" is deprecated.
 
* ApiFormatXml now assumes defaults and so on instead of throwing errors when
 
  metadata isn't set.
 
* (T35235) LogFormatter subclasses are now responsible for formatting log event
 
  parameters for the API.
 
* Many modules have changed result data formats. While this shouldn't affect
 
  clients not using the experimental formatversion=2, code using
 
  ApiResult::getResultData() without the transformations for backwards
 
  compatibility may need updating, as will code that wasn't following the old
 
  conventions for API boolean output.
 
* The following methods have been deprecated and may be removed in a future
 
  release:
 
  * ApiBase::getDescription
 
  * ApiBase::getParamDescription
 
  * ApiBase::getExamples
 
  * ApiBase::makeHelpMsg

* Changed parsing of variables in schema (.sql) files:
+
  mod_rewrite and adding the following rules to your configuration:
** The substituted values are no longer parsed. (Formerly, several passes
 
  were made for each variable, so depending on the order in which variables
 
  were defined, variables might have been found inside encoded values. This
 
  is no longer the case.)
 
** Variables are no longer string encoded when the /*$var*/ syntax is used.
 
  If string encoding is necessary, use the '{$var}' syntax instead.
 
** Variable names must only consist of one or more of the characters
 
  "A-Za-z0-9_".
 
** In source text of the form '{$A}'{$B}' or `{$A}`{$B}`, where variable A
 
  does not exist yet variable B does, the latter may not be replaced.
 
  However, this difference is unlikely to arise in practice.
 
* (T67278) RFC, PMID, and ISBN "magic links" must be surrounded by non-word
 
  characters on both sides.
 
* The FormatAutocomments hook will now receive $pre and $post as booleans,
 
   rather than as strings that must be prepended or appended to $comment.
 
* (T30950, T31025) RFC, PMID, and ISBN "magic links" can no longer contain
 
  newlines; but they can contain &nbsp; and other non-newline whitespace.
 
* The 'mediawiki.action.edit' ResourceLoader module no longer generates the edit
 
  toolbar, which has been moved to a separate 'mediawiki.toolbar' module. If you
 
  relied on this behavior, update your scripts' dependencies.
 
* HTMLForm's 'vform' display style has been separated to a subclass. Therefore:
 
  * HTMLForm::isVForm() is now deprecated.
 
  * You can no longer do this:
 
      $form = new HTMLForm( );
 
      $form->setDisplayFormat( 'vform' ); // throws exception
 
    Instead, do this:
 
      $form = HTMLForm::factory( 'vform', … );
 
* Deprecated Revision methods getRawUser(), getRawUserText() and getRawComment().
 
* BREAKING CHANGE: mediawiki.user.generateRandomSessionId:
 
  The alphabet of the prior string returned was A-Za-z0-9 and now it is 0-9A-F
 
* (T87504) Avoid serving SVG background-images in CSS for Opera 12, which
 
  renders them incorrectly when combined with border-radius or background-size.
 
* Removed maintenance script dumpSisterSites.php.
 
* DatabaseBase class constructors must be called using the array argument style.
 
  Ideally, DatabaseBase:factory() should be used instead in most cases.
 
* Deprecated ParserOutput::addSecondaryDataUpdate and ParserOutput::getSecondaryDataUpdates.
 
  This is a hard deprecation, with getSecondaryDataUpdates returning an empty array and
 
  addSecondaryDataUpdate throwing an exception. These functions will be removed in 1.26,
 
  since they interfere with caching of ParserOutput objects.
 
* Introduced new hook 'SecondaryDataUpdates' that allows extensions to inject custom updates.
 
* Introduced new hook 'OpportunisticLinksUpdate' that allows extensions to perform
 
  updates when a page is re-rendered.
 
* EditPage::attemptSave has been modified not to call handleStatus itself and
 
  instead just returns the Status object. Extension calling it should be aware of
 
  this.
 
* Removed class DBObject. (unused since 1.10)
 
* wfDiff() is deprecated.
 
* The -m (maximum replication lag) option of refreshLinks.php was removed.
 
  It had no effect since MediaWiki 1.18 and should be removed from any cron
 
  jobs or similar scripts you may have set up.
 
* (T85864) The following messages no longer support raw html: redirectto,
 
  thisisdeleted, viewdeleted, editlink, retrievedfrom, version-poweredby-others,
 
  retrievedfrom, thisisdeleted, viewsourcelink, lastmodifiedat, laggedslavemode,
 
  protect-summary-cascade
 
* All BloomCache related code has been removed. This was largely experimental.
 
* $wgResourceModuleSkinStyles no longer supports per-module local or remote paths. They
 
   can only be set for the entire skin.
 
* Removed global function swap(). (deprecated since 1.24)
 
* Deprecated the ".php5" file extension entry points and the $wgScriptExtension
 
  configuration variable. Refer to the ".php" files instead. If you want
 
  ".php5" URLs to continue to work, set up redirects. In Apache, this can be
 
  done by enabling mod_rewrite and adding the following rules to your
 
  configuration:
 
  
 
     RewriteEngine On
 
     RewriteEngine On
 
     RewriteBase /
 
     RewriteBase /

 +
* Article::doEditContent() was marked as deprecated, to be removed in 1.30
 +
  or later.
 +
* ContentHandler::runLegacyHooks() was removed.
 +
* refreshLinks.php now can be limited to a particular category with --category=...
 +
  or a tracking category with --tracking-category=...
 +
* User-like objects that are passed to SpecialUserRights and its subclasses are
 +
  now required to have a getGroupMemberships() method. See UserRightsProxy for
 +
  an example.
 +
* User::$mGroups (instance variable) was marked private. Use User::getGroups()
 +
  instead.
 +
* User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
 +
  User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
 +
  Use equivalent methods on the UserGroupMembership class.
 +
* Maintenance scripts and tests that call User::addGroup() must now ensure that
 +
  User objects have been added to the database prior to calling addGroup().
 +
* Protected function UsersPager::getGroups() was removed, and protected function
 +
  UsersPager::buildGroupLink() was changed from a static to an instance method.
 +
* The third parameter ($cache) to the UsersPagerDoBatchLookups hook was changed;
 +
  see docs/hooks.txt.
 +
* User::crypt() (deprecated in 1.24) was removed.
 +
* User::comparePasswords() (deprecated in 1.24) was removed.
 +
* ArchivedFile::getUserText() (deprecated in 1.23) was removed.
 +
* HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
 +
* BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
 +
  and subclasses.  It should only break if you call buildMainQueryConds
 +
  (changed to buildQuery with new signature) or doMainQuery (new
 +
  signature).  Subclasses are likely to call at least doMainQuery
 +
  (possibly both), but other classes might too, because they were
 +
  public.
 +
  Also, some related hooks were deprecated, but this is not yet a
 +
  breaking change.
 +
* Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
 +
* The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
 +
* WikiRevision::$fileIsTemp was deprecated.
 +
* WikiRevision::$importer was deprecated.
 +
* WikiRevision::$user was deprecated.
 +
* Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
 +
  WikiPage::PURGE_* constants are deprecated, and the functions will always
 +
  return false. They were a hack for an issue that has since been fixed.
 +
* Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
 +
  'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
 +
  if you don't actually care about checkboxes and just want to add some HTML
 +
  to the page.
 +
* Selflinks are now rendered as href-less <a> tags with the class mw-selflink
 +
  rather than <strong> tags. The old class name, "selflink", was deprecated
 +
  and will be removed in a future release. (T160480)
 +
* (T156184) $wgRawHtml will no longer apply to internationalization messages.
 +
* Browser support for non-ES5 JavaScript browsers, including Android 2,
 +
  Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
 +
* Removed wikibits global methods deprecated since MediaWiki 1.17 (T122755):
 +
  is_gecko, is_chrome_mac, is_chrome, webkit_version, is_safari_win, is_safari,
 +
  webkit_match, is_ff2, ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs,

  mwCustomEditButtons, injectSpinner, removeSpinner, escapeQuotes,
 +
  escapeQuotesHTML, jsMsg, addPortletLink, appendCSS, tooltipAccessKeyPrefix,
 +
  tooltipAccessKeyRegexp, updateTooltipAccessKeys.
 +
* The ID of the <li> element containing the login link has changed from
 +
  'pt-login' to 'pt-login-private' in private wikis.
 +
* The old, neglected "bulletin board style toolbar" in the edit form is now
 +
  deprecated (T30856). This old code dates from 2006, and was replaced in the
 +
  MediaWiki release tarball and in Wikimedia production by the WikiEditor
 +
  extension in 2010. It is only shown to users if no other editor was
 +
  installed, and leads to confusion.
 +
* (T92459) Loading ResourceLoader modules containing JavaScript through
 +
  addModuleStyles() is deprecated and will log a warning server-side.
  
* The global importScriptURI and importStylesheetURI functions, as well as the
+
== MediaWiki 1.28.3 ==
  loadedScripts object, from wikibits.js (deprecated since 1.17) now emit
 
  warnings through mw.log.warn when accessed.

* (T117899) SECURITY: $wgArticlePath can no longer be set to relative paths
 
  that do not begin with a slash. This enabled trivial XSS attacks.
 
  Configuration values such as "http://my.wiki.com/wiki/$1" are fine, as are

== MediaWiki 1.24.3 ==
+
=== Configuration changes in 1.28 ===
 +
* $wgSend404Code now affects status code of action=history if the page is not there.
 +
* BREAKING CHANGE: $wgHTTPProxy is now *required* for all external requests
 +
  made by MediaWiki via a proxy. Relying on the http_proxy environment
 +
  variable is no longer supported.
 +
* The load.php entry point now enforces the existing policy of not allowing
 +
  access to session data, which includes the session user and the session
 +
  user's language. If such access is attempted, an exception will be thrown.
 +
* The number of internal PBKDF2 iterations used to derive the session secret
 +
  is configurable via $wgSessionPbkdf2Iterations.
 +
* Upload dialog's file upload log comment can now be configured separately for
 +
  local and foreign uploads.
 +
* $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
 +
  signifies local uploads. A value of `[]` (empty array) now means that
 +
  no upload targets are allowed, effectively disabling the upload dialog.
 +
* The deprecated $wgEditEncoding variable has been removed; it was only used
 +
  for Esperanto language character conversion. You are now recommended to use
 +
  input methods provided by the UniversalLanguageSelector extension.
 +
* When $wgPingback is true, MediaWiki will periodically ping
 +
  https://www.mediawiki.org/beacon with basic information about the local
 +
  MediaWiki installation. This data includes, for example, the type of system,
 +
  PHP version, and chosen database backend. This behavior is off by default.
 +
* When $wgEditSubmitButtonLabelPublish is true, MediaWiki will label the button
 +
  to store-to-database-and-show-to-others as "Publish page"/"Publish changes";
 +
  if false, the default, they will be "Save page"/"Save changes".
 +
* The 'editcontentmodel' permission is now granted to all logged-in users ('user').
 +
  instead of just administrators ('sysop'). Documentation for this feature is
 +
  available at <https://www.mediawiki.org/wiki/Help:ChangeContentModel>.
 +
* $wgRevisionCacheExpiry is now set to one week by default instead of being disabled.
 +
* Magic links are now disabled by default, and can be re-enabled by modifying the value
 +
  of $wgEnableMagicLinks. Their usage is discouraged, but if they are manually enabled,
 +
  a tracking category will be added to help identify usage and make it easier to migrate
 +
  away from. If you depend upon magic link functionality, it is requested that you comment
 +
  on <https://www.mediawiki.org/wiki/Requests_for_comment/Future_of_magic_links> and
 +
  explain your use case(s).
 +
* New config variable $wgCSPFalsePositiveUrls to control what URLs to ignore
 +
  in upcoming Content-Security-Policy feature's reporting.
  
This is a security and maintenance release of the MediaWiki 1.24 branch.
+
=== New features in 1.28 ===
 +
* User::isBot() method for checking if an account is a bot role account.
 +
* Added a new 'slideshow' mode for galleries.
 +
* Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
 +
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
 +
  interact with API parsing.
 +
* Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
 +
  upload. Unlike 'UploadVerifyFile' it provides information about upload comment
 +
  and the file description page, but does not run for uploads to stash.
 +
* (T141604) Extensions can now provide a better error message when their
 +
  maintenance scripts are run without the extension being installed.
 +
* (T8948) Numeric sorting in categories is now supported by setting $wgCategoryCollation
 +
  to 'uca-default-u-kn' or 'uca-<langcode>-u-kn'. If you can't use UCA collations,
 +
  a 'numeric' collation is also available. If migrating from another
 +
  collation, you will need to run the updateCollation.php maintenance script.
 +
* Two new codes have been added to #time parser function: "xit" for days in current
 +
  month, and "xiz" for days passed in the year, both in Iranian calendar.
 +
* mw.Api has a new option, useUS, to use U+001F (Unit Separator) when
 +
  appropriate for sending multi-valued parameters. This defaults to true when
 +
  the mw.Api instance seems to be for the local wiki.
 +
* After a client performs an action which alters a database that has replica databases,
 +
  MediaWiki will wait for the replica databases to synchronize with the master database
 +
  while it renders the HTML output. However, if the output is a redirect to another wiki
 +
  on the wiki farm with a different domain, MediaWiki will instead alter the redirect
 +
  URL to include a ?cpPosTime parameter that triggers the database synchronization when
 +
  the URL is followed by the client. The same-domain case uses a new cpPosTime cookie.
 +
* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
 +
  'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
 +
  'show' parameters to existing API query modules.
  
=== Changes since 1.24.2 ===

 +
  the value of $wgMaxArticleSize.
 +
* Property 'modulemessages' from action=parse&prop=modules was removed
 +
  (deprecated since 1.26).
 +
* The following response properties from action=login, deprecated in 1.27, are
 +
  now removed: lgtoken, cookieprefix, sessionid. Clients should handle cookies
 +
  to properly manage session state.
 +
* Submitting the lgtoken and lgpassword parameters in the query string to
 +
  action=login is now deprecated and outputs a warning. They should be submitted
 +
  in the POST body instead.
 +
* Submitting sensitive authentication request parameters to action=clientlogin,
 +
  action=createaccount, action=linkaccount, and action=changeauthenticationdata
 +
  in the query string is now deprecated and outputs a warning. They should be
 +
  submitted in the POST body instead.
 +
* (T141960) Multi-valued parameters may now be separated using U+001F (Unit Separator)
 +
  instead of the pipe character. This will be useful if some of the multiple
 +
  values need to contain pipes, e.g. for action=options.
 +
* The API will now warn if input is not NFC-normalized Unicode or if it
 +
  contains invalid characters.
 +
* The 'normalized' list output by action=query and other modules that use
 +
  ApiPageSet may contain entries where the 'from' value is percent-encoded as
 +
  the raw value cannot be represented in a valid API response. These are
 +
  indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
 +
* (T28680) action=paraminfo can now return info about all submodules of a
 +
  module without listing them all explicitly.
 +
* (T146770) It is now possible to assert that the current user is a specific
 +
  named user, using the 'assertuser' parameter.

   'show' parameters to existing API query modules. A query module can enable
 +
  these hooks by passing an array for $hookData to ApiQueryBase::select() and
 +
  by calling ApiQueryBase->processRow() before adding a row's data to the
 +
   result.

changes to languages because of Phabricator reports.
 
 
* (bug T76686) [SECURITY] thumb.php outputs wikitext message as raw HTML, which
 
  could lead to xss. Permission to edit MediaWiki namespace is required to
 
  exploit this.
 
* (bug T77028) [SECURITY] Malicious site can bypass CORS restrictions in
 
  $wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as
 
  part of its name.

=== New features in 1.24 ===
 
* Added new hook WatchlistEditorBeforeFormRender, allowing subscribers to
 
  manipulate the list of pages and/or preload lots of data at once.
 
* Added new argument &$link in hook WatchlistEditorBuildRemoveLine, allowing the
 
  link to the title to be changed.
 
* Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
 
  WhatLinksHere entries.
 
* Added a new hook, "ContentGetParserOutput", to customize parser output for
 
  a given content object.
 
* Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
 
* HTMLForm's HTMLTextField now supports the 'url' type.
 
* HTMLForm fields may now be dynamically hidden based on the values of other
 
  fields in the form.
 
* HTMLForm now supports multiple copies of an input field or set of input
 
  fields, e.g. the form may request "one or more usernames" without having to
 
  have the user enter delimited list of names into a text field.
 
* Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
 
  the sidebar just before its display.
 
* (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
 
  jquery.cookie so that getting/setting a cookie is syntactically and
 
  functionally similar to using the WebRequest::getCookie() and
 
  WebResponse::setcookie() methods.
 
* (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
 
  $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
 
  and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
 
  This option is turned off by default, and will be removed in MediaWiki 1.25.
 
* (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
 
* Changes to content typography (fonts, etc.). See
 
  https://www.mediawiki.org/wiki/Typography_refresh for further information.
 
* WikitextContent will now render redirects with the expected "redirect"
 
  header, rather than as an ordered list. Code calling Article::viewRedirect
 
  can probably be changed to no longer special-case redirects.
 
* Header font set to a serif font stack. See
 
  https://www.mediawiki.org/wiki/Typography_refresh for further information.
 
* (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
 
  the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
 
  is only for page views, since this hook doesn't affect UserLogin, OAuth,
 
  CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
 
  overall design of the system.
 
* (bug 17367) It is now possible to add pages to your watchlist from
 
  Special:UnwatchedPages without reloading the special page.
 
* New methods setVolatile and isVolatile are added to PPFrame, so that
 
  extensions such as Cite.php can mark that their output is volatile and
 
  shouldn't be cached.
 
* (bug 52817) Advanced search options are now saved on the search page itself,
 
  rather than in a dedicated pane in the preferences panel.
 
* (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
 
  the Vector skin has gained a label that should make it more discoverable.
 
* MWCryptHKDF added for fast, cryptographically secure random number generation
 
  that won't deplete openssl's entropy pool.
 
* ResourceLoader: File modules can now provide a skip function that uses an
 
  inline feature test to bypass loading of the module.
 
* (bug 20210) Special pages may now provide autocompletion of their subpage
 
  names in search suggestions. Right now the only useful implementation is in
 
  Special:Log, but more are to come.
 
* Special:MostLinkedTemplates is no longer limited to transclusions from the
 
  Template namespace.
 
* Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
 
  This works the same as 'remoteExtPath' but is relative to the skins/ folder
 
  instead of the extensions/ folder.
 
* Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
 
  Exposed as module "json" with a skip function to optimise loading.
 
* Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
 
  to 'name', to allow for the name to be localizable. 'name' should still be
 
  specified for backwards-compatibility and to define the path Special:Version
 
  uses to find extension license information.
 
* Browser tests are now included to verify basic wiki functionality in developer
 
  environments. For details on running tests, see tests/browser/README.mediawiki.
 
* Upgrade jStorage to v0.4.10.
 
* {{!}} is now a magic word that produces the | character. This removes the need
 
  for Template:! for purposes such as passing pipes inside of parameters.
 
* (bug 20790) The block log snippet on Special:Contributions and while
 
  editing user and user talk pages now works for IP range blocks.
 
* (bug 9360) Added ability to change the page language for MediaWiki pages using
 
  Special:PageLanguage. All pages are set to wiki language by default.
 
  The feature needs to be enabled with $wgPageLanguageUseDB=true and
 
  permission needs to be set for 'pagelang'.
 
* Upgrade Moment.js to v2.8.3.
 
* (bug 67042) Added support for the HTML5 <rtc> tag for East Asian typography.
 
* Upgrade Sinon.JS to 1.10.3.
 
* Added the es5-shim polyfill for older or non-compliant javascript engines.
 
* Upgrade jQuery Cookie to v1.3.1.
 
* (bug 20476) Add a "viewsuppressed" user right to be able to view
 
  suppressed content but not suppress it ("suppressrevision" right).
 
* (bug 66440) The MediaWiki web installer will now allow you to choose the skins
 
  to enable (from the ones included in download tarball) and decide which one
 
  should be the default.
 
* (bug 68085, 68802) Links like [[localInterwikiPrefix:languageCode:pageTitle]],
 
  where localInterwikiPrefix is a member of the $wgLocalInterwikis array, will
 
  no longer be displayed in the sidebar when $wgInterwikiMagic is true. In a
 
  similar way, links like [[localInterwikiPrefix:File:Image.png]] and
 
  [[localInterwikiPrefix:Category:Hello]] will now render as regular links, and
 
  will not include the file or add the page to the category.
 
* New special page, MyLanguage, to redirect users to subpages with localised
 
  versions of a page. (Integrated from Extension:Translate)
 
* MediaWiki now supports multiple password types, including bcrypt and PBKDF2.
 
  The default type can be changed with $wgPasswordDefault and the type
 
  configurations can be changed with $wgPasswordConfig.
 
* Skins can now define custom styles for default ResourceLoader modules using
 
  the $wgResourceModuleSkinStyles global. See the Vector skin for examples.
 
* (bug 4488) There is now a preference to watch pages where the user has
 
  rollbacked an edit by default.
 
* (bug 15484) Users will now be redirected to the login page when they need to
 
  log in, rather than being shown a page asking them to log in and having to click
 
  another link to actually get to the login page.
 
* A JsonContent and JsonContentHandler were added for extensions to extend.
 
* (bug 35045) Redirects to sections will now update the URL in browser's address
 
  bar using the HTML5 History API. When [[Dog]] redirects to [[Animals#Dog]],
 
  the user will now see "Animals#Dog" in their browser instead of "Dog#Dog".
 
* API token handling has been rewritten. Any API module using tokens will need
 
  to be updated. See the entry below under "Action API internal changes".
 
* Added HTMLAutoCompleteSelectField.
 
* Added a new hook, "SkinPreloadExistence", to allow extensions to add titles to
 
  link existence cache before the page is rendered.
 
* Config::set() was moved to its own interface, MutableConfig. GlobalVarConfig::set()
 
  is now deprecated, does not implement MutableConfig.
 
* A MutableConfig named HashConfig was added, that stores an array of configuration
 
  settings.
 
* (bug 69418) A MultiConfig implementation was added that supports fallback
 
  to multiple Config instances.
 
* Update CSSJanus to v1.1.0.
 
* Added FormatJson::parse() returning status with result or localized error message
 
* Added DeletedContribsPager::reallyDoQuery hook allowing extensions to data to
 
  Special:DeletedContributions
 
* Added DeletedContributionsLineEnding hook allowing extensions to format
 
  Special:DeletedContributions lines
 
* (T69525) You can now make MediaWiki speed up its thumbnail rendering by using
 
  intermediary thumbnails. $wgThumbnailBuckets must be set to a list of target
 
  thumbnail widths; when a new thumbnail needs to be rendered, MediaWiki will
 
  find the smallest bucket smaller than the original but larger than the target
 
  width + $wgThumbnailMinimumBucketDistance, and it will scale that thumbnail,
 
  rather than the original, down to the target size at greater speed in return
 
  for minor loss of fidelity.
 
 
=== Bug fixes in 1.24 ===
 
* (bug 50572) MediaWiki:Blockip should support gender
 
* (bug 49116) Footer copyright notice is now always displayed in user language
 
  rather than content language (same as copyright notice for editing interface).
 
* (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
 
  restriction was present in the parameters. Images with both the "frame"
 
  option and a size specification set will now always ignore the provided
 
  size and display an unscaled image, as the documentation has always
 
  claimed it would.
 
* (bug 39035) Improved Vector skin performance by removing collapsibleNav,
 
  which used to collapse some sidebar elements by default.
 
  This removes -list id suffixes like p-lang-list: instead of using things like
 
  #p-lang-list, you can do #p-lang .body ul.
 
* (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
 
  follow redirects to their target pages.
 
* Parser now dies early if called recursively, instead of producing subtle bugs.
 
* (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
 
  remaining page content.
 
* (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
 
  in the file namespace and delete the file on the target page. It will still
 
  however delete the redirect page.
 
* (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
 
  recover the original code of extension tags.
 
* (bug 65757) MSSQL: Update script drops unnamed constraints to be prepared
 
  for future updates. Because it's doing so heuristically, it may fail or drop
 
  wrong constraints.
 
* (bug 67870) wfShellExec() cuts off stdout at multiples of 8192 bytes.
 
* $wgRunJobsAsync now works with private wikis (e.g. read requires login).
 
* (bugs 57238, 65206) Blank pages can now be directly created.
 
* (bug 69789) Title::getContentModel() now loads from the database when
 
  necessary instead of incorrectly returning the default content model.
 
* (bug 69249) wfBaseConvert() now works around PHP Bug #50175 when using GMP.
 
* (bug 57909) URLs in the externallinks table will no longer have certain
 
  characters decoded in the query string.
 
* (bug 67368) LESS mixins like .background-image() correctly flip image
 
  references for RTL stylesheets now.
 
 
=== Action API changes in 1.24 ===
 
* action=parse API now supports prop=modules, which provides the list of
 
  ResourceLoader modules that should be used to enhance the parsed content.
 
* action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 
  field which is true if protocol-relative urls can be used to access
 
  a particular interwiki map entry.
 
* list=logevents now provides logpage, which is the page ID from the
 
  logging table, if ids are requested and the user has the permissions.
 
* action=edit now requires that appendtext, prependtext, or section=new be used
 
  when using the 'redirect' parameter, to prevent clients accidentally
 
  overwriting the target page with the content of the redirect.
 
* list=logevents will now return an error if both letitle and leprefix are
 
  specified.
 
* list=logevents has a new parameter, lenamespace, to allow filtering by
 
  namespace.
 
* action=expandtemplates has a new parameter, prop, and a new output format.
 
  The old format is still used if prop isn't provided, but this is deprecated.
 
* meta=userinfo can now return the count of unread pages on the watchlist.
 
* list=watchlist can now filter by unread status.
 
* The deprecated action=parse&prop=languageshtml has been removed.
 
* (bug 48071) action=setnotificationtimestamp no longer throws PHP or database
 
  errors when no pages are given.
 
* (bug 60734) Actions that use ApiPageSet (e.g. purge, watch,
 
  setnotificationtimestamp) will now include continuation information when
 
  using a generator.
 
* Removed 'props' and 'errors' from action=paraminfo, as they have extremely
 
  limited use and are generally inaccurate, unmaintained, and impossible to
 
  properly maintain.
 
* Formats dbg, dump, txt, wddx, and yaml are now deprecated.
 
* action=paraminfo now indicates when a parameter is specifying a submodule.
 
* The iwurl parameter to prop=iwlinks is deprecated in favor of iwprop=url, for
 
  parallelism with prop=langlinks.
 
* All tokens should be fetched from action=query&meta=tokens; all other methods
 
  of fetching tokens are deprecated. The value needed for meta=tokens's 'type'
 
  parameter for each module is documented in the action=help output and is
 
  returned from action=paraminfo.
 
* New action ClearHasMsg that can be used to clear HasMsg flag.
 
* The cmstartsortkey and cmendsortkey parameters to list=categorymembers are
 
  deprecated in favor of cmstarthexsortkey and cmendhexsortkey.
 
* (bug 63326) Add blockedtimestamp field to output of blockinfo property for
 
  the list=allusers and list=users modules.
 
* prop=imageinfo no longer requires iiurlwidth to be set when using iiurlparam.
 
* Added prop=linkshere, prop=fileusage, and prop=transcludedin, which are
 
  roughly equivalent to list=backlinks, list=imageusage, and list=embeddedin
 
  but can work on a list of titles (including titles from a generator).
 
* prop=redirects can now filter returned redirects by namespace.
 
 
=== Action API internal changes in 1.24 ===
 
* Methods for handling continuation are added to ApiResult, so actions other
 
  than query that use generators can easily support continuation.
 
* $wgAPIModules (and the related $wgAPIFormatModules, $wgAPIMetaModules,
 
  $wgAPIPropModules, and $wgAPIListModules settings) now allow API modules
 
  to be specified using a "module spec" array instead of a plain class name.
 
  A "module spec" is an associative array containing at least the 'class' key
 
  for the module's class, and optionally a 'factory' key for the factory function
 
  to use for the module. This is intended for extensions that want control over
 
  the instantiation of their API modules, to allow for proper dependency
 
  injection.
 
* A new param type 'submodule' is available. Parameters of this type will take
 
  the list of valid values from the module's ApiModuleManager for the group
 
  corresponding to the parameter name.
 
* The 'APIGetPossibleErrors' and 'APIGetResultProperties' hooks are no longer used.
 
* API token handling has been rewritten. Any API module using tokens will need
 
  to be updated:
 
  * ApiBase::needsToken now returns a token type instead of boolean true when a
 
    token is needed. Returning true will throw an exception. See documentation
 
    of that method for details.
 
  * Information for the 'token' parameter is automatically set by ApiBase
 
    getFinalParams and getFinalParamDescription.
 
  * ApiBase::getTokenSalt has been removed.
 
  * The hooks APIQueryInfoTokens, APIQueryRevisionsTokens,
 
    APIQueryRecentChangesTokens, APIQueryUsersTokens, and
 
    ApiTokensGetTokenTypes are deprecated, but are still called to support
 
    backwards-compatible token access.
 
* ApiBase::validateLimit and ApiBase::validateTimestamp are now protected.
 
* ApiQueryRedirects was removed; prop=redirects is now implemented by
 
  ApiQueryBacklinksProp along with the newly-added prop modules.
 
* The following methods have been deprecated and may be removed in a future
 
  release:
 
  * ApiBase::getResultProperties
 
  * ApiBase::getFinalResultProperties
 
  * ApiBase::addTokenProperties
 
  * ApiBase::getRequireOnlyOneParameterErrorMessages
 
  * ApiBase::getRequireMaxOneParameterErrorMessages
 
  * ApiBase::getRequireAtLeastOneParameterErrorMessages
 
  * ApiBase::getTitleOrPageIdErrorMessage
 
  * ApiBase::getPossibleErrors
 
  * ApiBase::getFinalPossibleErrors
 
  * ApiBase::parseErrors
 
  * ApiQuery::setGeneratorContinue
 
  * ApiQueryBase::checkRowCount
 
  * ApiQueryBase::titleToKey
 
  * ApiQueryBase::keyToTitle
 
  * ApiQueryBase::keyPartToTitle
 
  * ApiQueryInfo::getTokenFunctions
 
  * ApiQueryInfo::resetTokenCache
 
  * ApiQueryInfo::getEditToken
 
  * ApiQueryInfo::getDeleteToken
 
  * ApiQueryInfo::getProtectToken
 
  * ApiQueryInfo::getMoveToken
 
  * ApiQueryInfo::getBlockToken
 
  * ApiQueryInfo::getUnblockToken
 
  * ApiQueryInfo::getEmailToken
 
  * ApiQueryInfo::getImportToken
 
  * ApiQueryInfo::getWatchToken
 
  * ApiQueryInfo::getOptionsToken

=== Languages updated in 1.24 ===
 
 
MediaWiki supports over 350 languages. Many localisations are updated
 
regularly. Below only new and removed languages are listed, as well as
 
changes to languages because of Bugzilla reports.
 
 
=== Other changes in 1.24 ===
 
* The deprecated jquery.delayedBind ResourceLoader module was removed.
 
* The deprecated function mw.util.toggleToc was removed.
 
* The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 
  were removed as they were unused.
 
* (bug 65477) User::pingLimiter() now has an additional profile point varying
 
  by action being used.
 
* mediawiki.util.$content no longer supports old versions of the Vector,
 
  Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 
  and/or "mw-body-primary" class name in their html.
 
* Added pp_sortkey column to page_props table, so pages can be efficiently
 
  queried and sorted by property value (bug 58032).
 
  See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 
* BREAKING CHANGE: All four built-in MediaWiki skins (Vector, MonoBook, Modern
 
  and Cologne Blue) were moved out of MediaWiki core to their own respective
 
  repositories. They will be installed with the release tarball, but you must
 
  install them separately if installing MediaWiki from source code. A warning
 
  message displayed until you do it should guide you through the process. See
 
  also <https://www.mediawiki.org/wiki/Manual:Skin_configuration>.
 
* BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 
  the "headelement" template key are no longer supported. Setting
 
  $useHeadElement = false; is no longer supported and will not cause old keys
 
  like "headlinks", "skinnameclass", etc. to be defined.
 
* BREAKING CHANGE: The files commonElements.css, commonContent.css and
 
  commonInterface.css (in skins/common/) have been removed. Skins may no longer
 
  rely on their presence and include them in their style modules. ResourceLoader
 
  modules introduced in MediaWiki 1.23 should be loaded instead:
 
  - skins/common/commonElements.css  → 'mediawiki.skinning.elements' module
 
  - skins/common/commonContent.css  → 'mediawiki.skinning.content' module
 
  - skins/common/commonInterface.css → 'mediawiki.skinning.interface' module
 
* The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 
* (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 
* SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 
  Special pages should subclass SpecialPage and implement the execute() method.
 
* (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 
  removed.
 
* Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 
* The skin autodiscovery mechanism has been deprecated and will be removed in
 
  MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 
  for migration guide for creators and users of custom skins that relied on it.
 
* ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
 
  skin style files used by the module.
 
* Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
 
* Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
 
* Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
 
* Removed info(), purge(), revert() and rollback() from the Article class; they
 
  have since become subclasses of the Action class. (deprecated since 1.19)
 
* SearchEngineReplacePrefixesComplete hook was removed.
 
* The "jquery.json" module has been deprecated. Use the "json" module instead.
 
* Removed HTMLForm::addJS(). (deprecated since 1.18)
 
* Removed LogEventsList::showHeader(). (deprecated since 1.19)
 
* Removed ImageGalleryBase::useSkin(). (deprecated since 1.18)
 
* Removed DatabaseMysqlBase::getLagFromProcesslist(). (deprecated since 1.19)

  set of hooks has been removed and replaced by a single new hook
 
  SpecialPageBeforeFormDisplay.

* Removed getFormFields(), onSubmit() and onSuccess() from FormlessAction, as
 
  these were meant specifically for FormAction instead.

* Removed AjaxAddScript which has been obsolete since ResourceLoader and
 
  is unused by any modern extension.

* Removed global function xmlsafe() from Export.php. (moved to OAIRepo extension)
 
* Removed Title::userCanRead(). (deprecated since 1.19)
 
* Removed maintenance script importTextFile.php. Use edit.php script instead.
 
* A _from_namespace field has been added to the templatelinks, pagelinks,
 
  and filelinks tables. Run update.php to apply this change to the schema.
 
* Removed File::sha1Base36(). (deprecated since 1.19)
 
* Removed File::getPropsFromPath(). (deprecated since 1.19)
 
* Removed functions blockedPage(), noCreatePermission(), readOnlyPage() and
 
  userNotLoggedInPage() from EditPage.php. (deprecated since 1.19)

  setPreloadedText() from EditPage.php. (deprecated since 1.21)
 
* Removed global functions wfArrayLookup(), wfArrayMerge(), wfDebugDieBacktrace()
 
  and wfTime(). (deprecated since 1.22)
 
* Browser support for Internet Explorer 6 and 7 lowered from Grade A to Grade C,
 
  meaning that JavaScript is no longer executed in these browser versions.
 
* Browser support for Opera 11 lowered from Grade A to Grade C.

  SpecialPageFactory::getNames()
 
* Action::checkCanExecute() no longer has a return value.

* Removed Xml::namespaceSelector(). (deprecated since 1.19)
 
* Removed WikiPage::estimateRevisionCount(). (deprecated since 1.19)
 
* MYSQL: Enum item added to "major MIME type" columns.
 
  Running update.php on MySQL < v5.1 may result in heavy processing.
 
* RSS and Atom feeds generated by MediaWiki no longer include a fallback
 
  stylesheet. It was ignored by most browsers these days anyway.
 
* SpecialSearchNoResults hook has been removed. SpecialSearchResults is now
 
  called unconditionally.
 
* TablePager::getBody() is now 'final' and can't be overridden in subclasses.
 
* TablePager::getBody() is deprecated, use getBodyOutput() or getFullOutput().
 
* Added $outputPage parameter to the SkinTemplateGetLanguageLink hook.
 
* log_page for move log entries store the original page ID, rather than that
 
  of the new redirect page. This is not retroactive.
 
* LCStoreAccel was removed. $wgLocalisationCacheConf can no longer be set to
 
  use this store class.
 
* Html::infoBox() no longer accepts paths relative to skins/common/images/.
 
* Deprecated defunct Skin::getCommonStylePath().
 
* Some extensions had their ResourceLoader modules depend on the "mediawiki"
 
  and "jquery" modules. In the past, this behavior was undefined, now it will
 
  throw an error.
 
* Removed BagOStuff::replace(). (deprecated since 1.23)
 
* In Linker.php, link(), linkText() and makeBrokenImageLinkObj() now display
 
  warnings if their first parameter is not a Title object. Also makeImageLink()
 
  now requires a Parser as its first parameter.
 
* (bug 67368) LESS functions embed() and embeddable(), added in MediaWiki 1.23
 
  and broken by design, have been removed. Use appropriate LESS mixins instead.
 
* Removed cssjanus.py from maintenance directory as it was unused.
 
* Removed maintenance/purgeOldText.inc and the PurgeRedundantText() function
 
  it contained (superseded by Maintenance::purgeRedundantText() in 1.16).
 
  The purgeOldText.php maintenance script has been retained.
 
* PHPUnit tests can be found by directory discovery, by adding the directory
 
  path from your UnitTestsList callback. Older versions of MediaWiki core will
 
  barf at this usage.

Version vom 22. Oktober 2018, 13:27 Uhr

Neue Versionen von Mediawiki bringen manchmal Voreinstellungen mit, die nicht unbedingt optimal sind. Diese Seite wird versuchen auf Veränderungen einzugehen.

Seiten und Dateien automatisch beobachten abstellen

Wer nicht möchte, dass man jedesmal automatisch per E-Mail benachrichtigt wird, falls man Seiten oder Dateien erstellt, verschiebt oder bearbeitet, sollte die Einstellungen seiner Beobachtungsliste anpassen. Ein Abschalten der entsprechenden Optionen bewirkt auch, dass bei der Seitenvorschau keine Vorauswahl bei "Diese Seite beobachten" aktiviert wird.

* (T200864) Fix pingback over-reporting on non-MySQL databases

* (T196092) Hide MySQL binary/utf-8 charset option in the installer.

* Do not incorrectly hide namespace input field in the installer.
* (T186456) Refactor checks looking for PEAR maik libraries to be clearer.

=== Important pre-upgrade notes for 1.31 ===
* If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
  schema changes, and cannot have downtime to run migrateArchiveText.php and
  apply patch-drop-ar_text.sql manually, you'll have to apply a default value
  to the ar_text and ar_flags columns of the archive table or make those
  columns nullable before upgrading to MediaWiki 1.31.
  maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
* The CologneBlue and Modern skins are no longer bundled with the tarball. You
  will need to remove the wfLoadSkin() calls from your LocalSettings.php or
  download them separately
  (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).

=== Configuration changes in 1.31 ===
* $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
  a future version. The API is now considered to be stable, secure and
  essential.
* $wgUsejQueryThree was removed, as it is now the default. This was documented
  as a temporary variable during the migration period, deprecated since 1.29.
* $wgLogoHD has been updated to support svg images and uses $wgLogo where
  possible for fallback images such as png.
* (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
  have the right to mark things patrolled.
* Wikis that contain imported revisions or CentralAuth global blocks should run
  maintenance/cleanupUsersWithNoId.php.
* The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
  $wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
* (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
  are not using the latest version of the Referrer Policy specification.
* $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
  first step of migration to human-readable section IDs that will later result
  in 'html5' being the default mode.
* CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
  as upstream is inactive and has no plans to move to PHP 7.
* The old CategorizedRecentChanges feature, including its related configuration
  option $wgAllowCategorizedRecentChanges, has been removed.
* (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
  for performance reasons, and installations with this setting will now work as
  if it was configured with 'any'.
* (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
  rather than being off by default. If you wish to disable HTML tidying
  entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
  Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
* $wgLogAutopatrol now defaults to false instead of true.
* $wgValidateAllHtml was removed and will be ignored.
* $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
  1.25 release notes for more information.
* $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
  framework that it enables. Some extensions mistakenly used this to check
  whether any AJAX functionality at all should be enabled, further making this
  problematic to retain.
* $wgDBmysql5 is now deprecated, and will be removed in a future version. It
  has been marked as experimental ever since it was introduced.

=== New features in 1.31 ===
* (T76554) User sub-pages named ….json are now protected in the same way that
  ….js and ….css pages are, so that configuration options can safely be placed
  there.
* Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
  with parentheses for grouping.
* As a first pass in standardizing dialog boxes across the MediaWiki product,
  Html class now provides helper methods for messageBox, successBox, errorBox
  and warningBox generation.
* (T9240) Imports will now record unknown (and, optionally, known) usernames in
  a format like "iw>Example".
* (T20209) Linker (used on history pages, log pages, and so on) will display
  usernames formed like "iw>Example" as interwiki links, as if by wikitext like
  [[iw:User:Example|iw>Example]].
* (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
  users during an import.
* Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
  the ParserOutput::getText() post-cache transformations.
* Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
  initial page text for file uploads.
* (T181651) The info page for File pages now displays the file's base-16 SHA1
  hash value in the table of basic information.
* Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
  ParserOutput::getText() post-cache transformation. This may be disabled by
  passing 'deduplicateStyles' => false to that method.
* The identity of the logged-in or IP "actor" for logged actions is being moved
  into a new actor table, with the rows in tables such as revision and logging
  referring to the actor ID instead of storing the user ID and name/IP in
  every row.
  * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
    can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
    soon as any necessary extensions are updated.
  * Most code accessing rows for logged actions from the database should use
    the relevant getQueryInfo() methods to get the information needed to build
    the SQL query. The ActorMigration class may also be used to get feature
    -flagged information needed to access actor-related fields during the
    migration period.
* Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
  section without having to roll back the whole transaction.
* Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
  and non-MySQL ::replace() and ::upsert() no longer roll back the whole
  transaction on failure.
* (T189785) Added a monthly heartbeat ping to the pingback feature.
* The CLI installer (maintenance/install.php) learned to detect and include
  extensions. Pass --with-extensions to enable that feature.
* (T184791) rc_patrolled now has three states: "0" for unpatrolled,
  "1" for manually patrolled and "2" for autopatrolled actions.
* Extensions can now set their type to "editor" if they provide an editor or
  enhance the editing experience.
* Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
  property in extension.json. See the documentation at
  <https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
  for more details and an example.
* (T19099) Tabs which link to pages that don't exist (like those to uncreated
  discussion pages) now have a tooltip to indicate state, not just colour.

  were logged as errors. The startAtomic() and endAtomic() methods, or
  AtomicSectionUpdate should be used instead.
* The global function wfOutputHandler() was removed, use the its replacement

  RevisionRecord and its subclasses.
* The global function wfBCP47 is deprecated in favour of LanguageCode::bcp47.
* The global function wfCountDown is now deprecated in favor of
  Maintenance::countDown.
* Several methods for returning lists of fields to select from the database
  have been deprecated in favor of similar methods that also return the tables
  to select from and the join conditions for those tables.
  * Block::selectFields() → Block::getQueryInfo()
  * RecentChange::selectFields() → RecentChange::getQueryInfo()
  * ArchivedFile::selectFields() → ArchivedFile::getQueryInfo()
  * LocalFile::selectFields() → LocalFile::getQueryInfo()
  * LocalFile::getCacheFields() with a prefix no longer works
  * LocalFile::getLazyCacheFields() with a prefix no longer works

  override DifferenceEngine::getDiffBodyCacheKeyParams() instead.
* Use of Maintenance::error( $err, $die ) to exit script was deprecated. Use
  Maintenance::fatalError() instead.

* License::getLicenses has been deprecated; use License::getLines instead.
* QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().

  * Parser::serializeHalfParsedText()
  * Parser::unserializeHalfParsedText()
  * Parser::isValidHalfParsedText()
  * StripState::getSubState()

  will be allowed to provide any HTMLForm object rather than PreferencesForm.

=== Other changes in 1.31 ===
* Browser support for Internet Explorer 10 was lowered from Grade A to Grade C.
* Browser support for Opera 12 and older was dropped entirely. Opera 15+
  continues at Grade A.

  Links written using square brackets will get the class "text" not "free".
* RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
  wikitext table captions, wikitext table headings, wikitext table cells. HTML
  headings, HTML list items, HTML table captions, HTML table headings, HTML
  table cells will not have this trimming behavior.

=== MySQL version requirement in 1.30 ===
As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
section).

=== Configuration changes in 1.30 ===
* The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
  unexpected behavior when code uses locale-sensitive string comparisons. For
  example, the Scribunto extension considers "bar" < "Foo" in most locales
  since it ignores case.
* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
  documentation of $wgShellLocale for details.
* $wgShellLocale is now applied for all requests. wfInitShellLocale() is
  deprecated and a no-op, as it is no longer needed.
* $wgJobClasses may now specify callback functions as an alternative to plain
  class names. This is intended for extensions that want control over the
  instantiation of their jobs, to allow for proper dependency injection.
* $wgResourceModules may now specify callback functions as an alternative
  to plain class names, using the 'factory' key in the module description
  array. This allows dependency injection to be used for ResourceLoader modules.
* $wgExceptionHooks has been removed.
* (T163562) $wgRangeContributionsCIDRLimit was introduced to control the size
  of IP ranges that can be queried at Special:Contributions.
* (T45547) $wgUsePigLatinVariant added (off by default).
* (T152540) MediaWiki now supports a section ID escaping style that allows to display
  non-Latin characters verbatim on many modern browsers. This is controlled by the
  new configuration setting, $wgFragmentMode.
* $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
  use $wgFragmentMode to migrate off it to a modern alternative.
* $wgExternalInterwikiFragmentMode was introduced to control how fragments in
  sinterwikis going outside of current wiki farm are encoded.
* (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
  This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
  auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
  requested through the configuration parameter $wgDBservers.
* $wgOOUIEditPage was removed, as it is now the default. This was documented as a
  temporary variable during the migration period.

=== New features in 1.30 ===
* (T37247) Output from Parser::parse() will now be wrapped in a div with
  class="mw-parser-output" by default. This may be changed or disabled using
  ParserOptions::setWrapOutputClass().
* (T163562) Added ability to search for contributions within an IP ranges
  at Special:Contributions.
* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  specific tags to be added by users.
* Added a 'ParserOptionsRegister' hook to allow extensions to register
  additional parser options.
* (T45547) Included Pig Latin, a language game in English, as a
  LanguageConverter variant.  This allows English-speaking developers
  to develop and test LanguageConverter more easily.  Pig Latin can be
  enabled by setting $wgUsePigLatinVariant to true.
* Added RecentChangesPurgeRows hook to allow extensions to purge data that
  depends on the recentchanges table.
* Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
* (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
  'watchlistunwatchlinks' preference option is enabled). With JavaScript
  enabled, these links toggle so the user can also re-watch pages that have
  just been unwatched.
* Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
  MediaHandlerFactory for parser tests.
* Edit summaries, block reasons, and other "comments" are now stored in a
  separate database table. Use the CommentFormatter class to access them.
** This is currently gated by $wgCommentTableSchemaMigrationStage. Most wikis
   can set this to MIGRATION_NEW and run maintenance/migrateComments.php as
   soon as any necessary extensions are updated.
* (T138166) Added ability for users to prohibit other users from sending them
  emails with Special:Emailuser. Can be enabled by setting
  $wgEnableUserEmailBlacklist to true.
* (T67297) $wgBrowserBlacklist is deprecated, and changing it will have no effect.
  Instead, users using browsers that do not support Unicode will be unable to edit
  and should upgrade to a modern browser instead.

=== External library changes in 1.30 ===

==== Upgraded external libraries ====
* Updated justinrainbow/json-schema from v3.0 to v5.2.

=== Bug fixes in 1.30 ===
* (T151633) Ordered list items use now Devanagari digits in Nepalese
  (thanks to Sfic)

=== Action API changes in 1.30 ===
* (T37247) action=parse output will be wrapped in a div with
  class="mw-parser-output" by default. This may be changed or disabled using
  the new 'wrapoutputclass' parameter.
* When errorformat is not 'bc', abort reasons from action=login will be
  formatted as specified by the error formatter parameters.
* action=compare can now handle arbitrary text, deleted revisions, and
  returning users and edit comments.
* (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  parameters to prop=revisions are deprecated, as are the similarly named
  parameters to prop=deletedrevisions, list=allrevisions, and
  list=alldeletedrevisions. Use action=compare, action=parse, or
  action=expandtemplates instead.

=== Action API internal changes in 1.30 ===
* ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  deprecated. The existing message should be split between "apihelp-*-summary"
  and "apihelp-*-extended-description".
* (T123931) Individual values of multi-valued parameters can now be marked as
  deprecated.

=== Languages updated in 1.30 ===
MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Phabricator reports.

* Added: kbp (Kabɩyɛ / Kabiyè)

* Added: tay (Tayal / Atayal)
* Removed: tokipona (Toki Pona)

==== Pig Latin added ====
* (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
  for easier variant development and testing. Disabled by default. It can be
  enabled by setting $wgUsePigLatinVariant to true.

=== Other changes in 1.30 ===
* The use of an associative array for $wgProxyList, where the IP address is in
  the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
  Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
* mw.user.bucket (deprecated in 1.23) was removed.
* LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
  deprecated. There are no known callers.

  deprecated in 1.24) were removed.
* wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
  BagOStuff::makeGlobalKey() should be used instead.
* (T146304) Preprocessor handling of LanguageConverter markup has been improved.
  As a result of the new uniform handling, '-{' may need to be escaped
  (for example, as '-<nowiki/>{') where it occurs inside template arguments
  or wikilinks.
* (T163966) Page moves are now counted as edits for the purposes of
  autopromotion, i.e., they increment the user_editcount field in the database.
* Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
  manipulating Special:Log and Special:NewPages lines.
* The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
  PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
  hooks have an additional parameter, for manipulating HTML data attributes of
  RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
  $data['attribs'] subarray.
* (T130632) The OutputPage::enableTOC() method was removed.
* WikiPage::getParserOutput() will now throw an exception if passed
  ParserOptions that would pollute the parser cache. Callers should use
  WikiPage::makeParserOptions() to create the ParserOptions object and only
  change options that affect the parser cache key.
* Article::viewRedirect() is deprecated.
* IP::isValidBlock() was deprecated. Use the equivalent IP::isValidRange().
* DeprecatedGlobal no longer supports passing in a direct value, it requires a
  callable factory function or a class name.
* The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
  are all deprecated. The main ParserCache instance should be obtained from
  MediaWikiServices instead. Access to the underlying BagOStuff is possible
  through the new ParserCache::getCacheStorage() method.
* .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
* Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),

  Sanitizer functions or, if possible, Title::getFragmentForURL().
* Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
  nothing and is deprecated.

  escapeIdForLink().
* MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
* WikiImporter now requires the second parameter to be an instance of the Config,
  class. Prior to that, the Config parameter was optional (a behavior deprecated in

* Removed 'jquery.mwExtension' module. (deprecated since 1.26)
* mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
  any more.

    use ::getSummaryInputWidget() instead.
  * EditPage::getCheckboxes() and ::getCheckboxesOOUI() are deprecated. Please
    use ::getCheckboxesWidget() instead.

    be avoided and will be deprecated in a future release.
  * EditPage::safeUnicodeInput() and ::safeUnicodeOutput() are deprecated and no-ops.
  * EditPage::$isCssJsSubpage, ::$isCssSubpage, and ::$isJsSubpage are deprecated. The
    corresponding methods from Title should be used instead.
  * EditPage::$isWrongCaseCssJsPage is deprecated. There is no replacement.
  * EditPage::$mArticle and ::$mTitle are deprecated for public usage. The getters
    ::getArticle() and ::getTitle() should be used instead.
  * Trying to control or fake EditPage context by overriding $wgUser, $wgRequest, $wgOut,
    and $wgLang is no longer supported and won't work. The IContextSource returned from
    EditPage::getContext() must be modified instead.
* Parser::getRandomString() (deprecated in 1.26) was removed.
* Parser::uniqPrefix() (deprecated in 1.26) was removed.
* Parser::extractTagsAndParams() now only accepts three arguments. The fourth,
  $uniq_prefix was deprecated in 1.26 and has now been removed.
* (T172514) The following tables have had their UNIQUE indexes turned into proper
  PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
  langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
  templatelinks, text, transcache, user_former_groups, user_properties.
* IDatabase::nextSequenceValue() is no longer needed by any database backends
  (formerly it was needed by PostgreSQL and Oracle), and is now deprecated.
* (T146591) The lc_lang_key index on the l10n_cache table has been changed into a
  PRIMARY KEY.
* (T157227) bot_password.bp_user, change_tag.ct_log_id, change_tag.ct_rev_id,
  page_restrictions.pr_user, tag_summary.ts_log_id, tag_summary.ts_rev_id and
  user_properties.up_user have all been made unsigned on MySQL.
* DB_SLAVE is deprecated. DB_REPLICA should be used instead.
* wfUsePHP() is deprecated.
* wfFixSessionID() was removed.
* wfShellExec() and related functions are deprecated, use Shell::command(). This also
  slightly changes the behavior of how execution time limits are calculated when only
  some of defaults are overridden per-call. When in doubt, always override both wall
  clock and CPU time.
* (T138166) SpecialEmailUser::getTarget() now requires a second argument, the sending
  user object. Using the method without the second argument is deprecated.
* (T67297) Browsers that don't support Unicode will have their edits rejected.
* (T178450) The module 'jquery.badge' is deprecated and will be removed in a future

== MediaWiki 1.29.1 ==

This is a maintenance release of the MediaWiki 1.29 branch.

packages.

=== Changes since 1.29.1 ===
* (T164999) Define mw.Upload.Dialog.static.name in mediawiki.Upload.Dialog.js.
* (T172061) Fix fatal when passing a category to refreshLinks.php.

== MediaWiki 1.29 ==

=== Configuration changes in 1.29 ===
* Default cookie expiration time has been reduced to 30 days. Login cookie
  expiration time is kept at 180 days.
* A new configuration variable has been added: $wgCookieSetOnAutoblock. This
  determines whether to set a cookie when a user is autoblocked. Doing so means
  that a blocked user, even after logging out and moving to a new IP address,
  will still be blocked.
* The resetpassword right and associated password reset capture feature has
  been removed.
* The $error parameter to the EmailUser hook should be set to a Status object
  or boolean false. This should be compatible with at least MediaWiki 1.23 if
  not earlier. Returning a raw HTML string is now deprecated.
* The $message parameter to the ApiCheckCanExecute hook should be set to an
  ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  code for ApiBase::parseMsg() will no longer work.
* ApiBase::$messageMap is no longer public. Code attempting to access it will
  result in a PHP fatal error.
* $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
  policies.
* Subpages are now enabled by default in the Template namespace. Set
  $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
* $wgRunJobsAsync is now false by default (T142751). This change only affects
  wikis with $wgJobRunRate > 0.
* (T158474) "Unknown user" has been added to $wgReservedUsernames.
* (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
* $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
  added to $wgExtraLanguageCodes instead.
* (T161453) LocalisationCache will no longer use the temporary directory in it's
  fallback chain when trying to work out where to write the cache.
* The user right 'editusercssjs' (deprecated in 1.16) was removed. Use
  'editusercss' and 'edituserjs' in $wgGroupPermissions and elsewhere instead.

=== New features in 1.29 ===
* (T5233) A cookie can now be set when a user is autoblocked, to track that user
  if they move to a new IP address. This is disabled by default.
* Added ILocalizedException interface to standardize the use of localized
  exceptions, largely so the API can handle them more sensibly.
* Blocks created automatically by MediaWiki, such as for configured proxies or
  dnsbls, are now indicated as such and use a new i18n message when displayed.
* Added new $wgHTTPImportTimeout setting. Sets timeout for
  downloading the XML dump during a transwiki import in seconds.
* Parser limit report is now available in machine-readable format to JavaScript
  via mw.config.get('wgPageParseReport').
* Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  from certain IP ranges (e.g. private IPs).
* (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  of the page being parsed.
* HTML5 form validation attributes will no longer be suppressed. Originally
  browsers had poor support for them, but modern browsers handle them fine.
  This might affect some forms that used them and only worked because the
  attributes were not actually being set.
* Expiry times can now be specified when users are added to user groups.
* Completely new user interface for the RecentChanges page, which
  structures filters into user-friendly groups.  This has corresponding
  changes to how filters are registered by core and extensions.
* The edit form now uses pretty OOjs UI buttons, checkboxes and summary input.
  Because this change can cause problems for extensions and on-wiki
  scripts depending on the exact HTML, the old version is still available
  and can be used by setting $wgOOUIEditPage = false; in LocalSettings.php.
  This will be removed later and OOjs UI will become the only option.
  To make testing easier, users can also force either mode by adding
  &ooui=true or &ooui=false to the action=edit URL.

=== External library changes in 1.29 ===

* (T160519) CACHE_ANYTHING will not be CACHE_ACCEL if no accelerator is installed.
* (T109140) (T122209) SECURITY: Special:UserLogin and Special:Search allow redirect
  to interwiki links.
* (T144845) SECURITY: XSS in SearchHighlighter::highlightText() when
  $wgAdvancedSearchHighlighting is true.
* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
  their values out of the logs.
* (T150044) SECURITY: "Mark all pages visited" on the watchlist now requires a CSRF
  token.
* (T156184) SECURITY: Escape content model/format url parameter in message.
* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
  declaration.
* (T161453) SECURITY: LocalisationCache will no longer use the temporary directory
  in it's fallback chain when trying to work out where to write the cache.
* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file inclusion
  syntax's link parameter.
* (T108138) SECURITY: Sysops can undelete pages, although the page is protected against
  it.

=== Action API changes in 1.29 ===
* Submitting sensitive authentication request parameters to action=login,
  action=clientlogin, action=createaccount, action=linkaccount, and
  action=changeauthenticationdata in the query string is now an error. They
  should be submitted in the POST body instead.
* The capture option for action=resetpassword has been removed
* action=clearhasmsg now requires a POST.
* (T47843) API errors and warnings may be requested in non-English languages
  using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
* API error codes may have changed. Most notably, errors from modules using
  parameter prefixes (e.g. all query submodules) will no longer be prefixed.
* ApiPageSet-using modules will report the 'invalidreason' using the specified
  'errorformat'.
* action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  'errors' subelements (as applicable) instead of 'message'.
* action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
* action=move now reports errors when moving the talk page as an array under
  key 'talkmove-errors', rather than using 'talkmove-error-code' and
  'talkmove-error-info'. The format for subpage move errors has also changed.
* action=revisiondelete no longer includes a "rendered" property on warnings
  and errors for each item. Use errorformat=wikitext if you're wanting parsed
  output.
* action=rollback no longer returns a "messageHtml" property. Use
  errorformat=html if you're wanting HTML formatting of error messages.
* action=upload now reports optional stash failures as an array under key
  'stasherrors' rather than a 'stashfailed' text string.
* action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  no longer returns a 'message' on success.
* Added action=validatepassword to validate passwords for the account creation
  and password change forms.
* action=purge now requires a POST.
* There is a new `languagevariants` siprop for action=query&meta=siteinfo,
  which returns a list of languages with active LanguageConverter instances.
* action=query&query=allpages will no longer filter redirects using a database
  query in miser mode. This may result in less results being returned than were
  requested.

=== Action API internal changes in 1.29 ===
* New methods were added to ApiBase to handle errors and warnings using i18n
  keys. Methods for using hard-coded English messages were deprecated:
  * ApiBase::dieUsage() was deprecated
  * ApiBase::dieUsageMsg() was deprecated
  * ApiBase::dieUsageMsgOrDebug() was deprecated
  * ApiBase::getErrorFromStatus() was deprecated
  * ApiBase::parseMsg() was deprecated
  * ApiBase::setWarning() was deprecated
* ApiBase::$messageMap is no longer public. Code attempting to access it will
  result in a PHP fatal error.
* The $message parameter to the ApiCheckCanExecute hook should be set to an
  ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  code for ApiBase::parseMsg() will no longer work.
* UsageException is deprecated in favor of ApiUsageException. For the time
  being ApiUsageException is a subclass of UsageException to allow things that
  catch only UsageException to still function properly.
* If, for some strange reason, code was using an ApiErrorFormatter instead of
  ApiErrorFormatter_BackCompat, note that the result format has changed and
  various methods now take a module path rather than a module name.
* ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
  from the message key, and maps some message keys for backwards compatibility.
* API parameters may now be marked as "sensitive" to keep their values out of
  the logs.

=== extension.json changes in 1.29 ===
* Extensions must set a value for "manifest_version" in their extension.json
  or skin.json files. See
  <https://www.mediawiki.org/wiki/Manual:Extension.json/Schema#manifest_version>
  for details.
* Extensions can now specify dependencies upon other extensions by using the
  "requires" key. See
  <https://www.mediawiki.org/wiki/Manual:Extension.json/Schema#requires> for
  more details.
* (T151136) Functions set as the "callback" now recieve that extension's credits
  information as the first argument.
* (T149597) "PasswordPolicy" can be set in extension.json.

=== Languages updated in 1.29 ===

MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Phabricator reports.

* Based as always on linguistic studies on intelligibility and language
  knowledge by geography, language fallbacks have been expanded. When a
  translation is missing in the user's preferred interface language, the
  corresponding translation for the fallback language will be used instead.
  English will only be used as last resort when there are no translations.
  Some configurations (such as date formats and gender namespaces) have also
  been updated when using the fallback language's configuration was inadequate.
  The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
  ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
  sh → bs, sr-el, hr.
* (T137376) New language support: Atikamekw (atj).
* (T163600) New language support: Dinka (din).
* (T155957) Talk Namespaces for Javanese language (jv) have been updated.

==== No fallback for Ukrainian ====
* (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
  language will now use the default fallback language: English. When a translation
  to Ukrainian is not available, an English string will be shown.

=== Other changes in 1.29 ===
* Database::getSearchEngine() (deprecated in 1.28) was removed. Use
  SearchEngineFactory::getSearchEngineClass() instead.
* $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
  required as all sessions are stored in Object Cache now.
* MWHttpRequest::execute() should be considered to return a StatusValue; the
  Status return type is deprecated.

* Xml::escapeJsString() (deprecated in 1.21) was removed.
* Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
  were removed.

* User-like objects that are passed to SpecialUserRights and its subclasses are
  now required to have a getGroupMemberships() method. See UserRightsProxy for
  an example.
* User::$mGroups (instance variable) was marked private. Use User::getGroups()
  instead.
* User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
  User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
  Use equivalent methods on the UserGroupMembership class.
* Maintenance scripts and tests that call User::addGroup() must now ensure that
  User objects have been added to the database prior to calling addGroup().
* Protected function UsersPager::getGroups() was removed, and protected function
  UsersPager::buildGroupLink() was changed from a static to an instance method.
* The third parameter ($cache) to the UsersPagerDoBatchLookups hook was changed;
  see docs/hooks.txt.

* User::comparePasswords() (deprecated in 1.24) was removed.
* ArchivedFile::getUserText() (deprecated in 1.23) was removed.
* HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
* BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
  and subclasses.  It should only break if you call buildMainQueryConds
  (changed to buildQuery with new signature) or doMainQuery (new
  signature).  Subclasses are likely to call at least doMainQuery
  (possibly both), but other classes might too, because they were
  public.
  Also, some related hooks were deprecated, but this is not yet a
  breaking change.
* Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
* The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
* WikiRevision::$fileIsTemp was deprecated.
* WikiRevision::$importer was deprecated.
* WikiRevision::$user was deprecated.
* Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
  WikiPage::PURGE_* constants are deprecated, and the functions will always
  return false. They were a hack for an issue that has since been fixed.
* Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
  'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
  if you don't actually care about checkboxes and just want to add some HTML
  to the page.
* Selflinks are now rendered as href-less <a> tags with the class mw-selflink
  rather than <strong> tags. The old class name, "selflink", was deprecated
  and will be removed in a future release. (T160480)
* (T156184) $wgRawHtml will no longer apply to internationalization messages.
* Browser support for non-ES5 JavaScript browsers, including Android 2,
  Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
* Removed wikibits global methods deprecated since MediaWiki 1.17 (T122755):
  is_gecko, is_chrome_mac, is_chrome, webkit_version, is_safari_win, is_safari,
  webkit_match, is_ff2, ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs,
  opera7_bugs, opera6_bugs, is_opera_95, is_opera_preseven, is_opera,
  ie6_bugs, clientPC, changeText, killEvt, addHandler, hookEvent,
  addClickHandler, removeHandler, getElementsByClassName, getInnerText,
  setupCheckboxShiftClick, addCheckboxClickHandlers, mwEditButtons,
  mwCustomEditButtons, injectSpinner, removeSpinner, escapeQuotes,

* The ID of the <li> element containing the login link has changed from
  'pt-login' to 'pt-login-private' in private wikis.
* The old, neglected "bulletin board style toolbar" in the edit form is now
  deprecated (T30856). This old code dates from 2006, and was replaced in the
  MediaWiki release tarball and in Wikimedia production by the WikiEditor
  extension in 2010. It is only shown to users if no other editor was
  installed, and leads to confusion.
* (T92459) Loading ResourceLoader modules containing JavaScript through
  addModuleStyles() is deprecated and will log a warning server-side.

== MediaWiki 1.28.2 ==

Due to a packaging error, the wrong version of the SyntaxHighlight extension was
included in the tarball version of MediaWiki 1.28.1. The version included had a
serious security issue in it (T158689). There was also some minor code fixes in
MediaWiki itself since 1.28.1, but none of them were security relevant.

== MediaWiki 1.28.1 ==

This is a security and maintenance release of the MediaWiki 1.28 branch.

=== Changes since 1.28.0 ===

* $wgRunJobsAsync is now false by default (T142751). This change only affects
  wikis with $wgJobRunRate > 0.
* Fix fatal from "WaitConditionLoop" not being found, experienced when a wiki has
  more than one database server setup.
* (T152717) Better escaping for PHP mail() command,

  syntax's link parameter.
* (T108138) SECURITY: Sysops can undelete pages, although the page is protected against
  it.

== MediaWiki 1.28 ==

=== Changes since 1.28.0-rc1 ===
* (T148957) Replace wgShowExceptionDetails with wgShowDBErrorBacktrace on db
  errors.
* (T148956) Only apply wgDBschema to postgres/mssql.
* (T145991) Introduce separate log action for deleting pages on move.
* (T141474) (T110464) Bypass login page if no user input is required.

=== Changes since 1.28.0-rc0 ===
* (T142210) The changes to move the parser "NewPP limit report" from a HTML
  comment to a machine-readable JavaScript config option 'wgPageParseReport'
  have been undone. They caused the human-readable limit report to be shown
  incompletely or not at all. ParserOutput::setLimitReportData() and
  getLimitReportData() behave as they did in MediaWiki 1.27 again.
* (T149510) Value of {{DISPLAYTITLE:}} parser function will not be used for
  the text of subheadings on a category page when creating it. This wasn't
  working correctly.
* (T106793) MediaWiki will no longer try to perform a HTTP redirect to the
  canonical pretty URL when a non-pretty URL is used. It resulted in redirect
  loops in some clients and in some server configurations. This undoes a change
  made in MediaWiki 1.26.
* (T149759) manifest_version: 2 was removed.

=== Configuration changes in 1.28 ===
* $wgSend404Code now affects status code of action=history if the page is not there.
* BREAKING CHANGE: $wgHTTPProxy is now *required* for all external requests
  made by MediaWiki via a proxy. Relying on the http_proxy environment
  variable is no longer supported.
* The load.php entry point now enforces the existing policy of not allowing
  access to session data, which includes the session user and the session
  user's language. If such access is attempted, an exception will be thrown.
* The number of internal PBKDF2 iterations used to derive the session secret
  is configurable via $wgSessionPbkdf2Iterations.
* Upload dialog's file upload log comment can now be configured separately for
  local and foreign uploads.
* $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
  signifies local uploads. A value of `[]` (empty array) now means that
  no upload targets are allowed, effectively disabling the upload dialog.
* The deprecated $wgEditEncoding variable has been removed; it was only used
  for Esperanto language character conversion. You are now recommended to use
  input methods provided by the UniversalLanguageSelector extension.
* When $wgPingback is true, MediaWiki will periodically ping
  https://www.mediawiki.org/beacon with basic information about the local
  MediaWiki installation. This data includes, for example, the type of system,
  PHP version, and chosen database backend. This behavior is off by default.
* When $wgEditSubmitButtonLabelPublish is true, MediaWiki will label the button
  to store-to-database-and-show-to-others as "Publish page"/"Publish changes";
  if false, the default, they will be "Save page"/"Save changes".
* The 'editcontentmodel' permission is now granted to all logged-in users ('user').
  instead of just administrators ('sysop'). Documentation for this feature is
  available at <https://www.mediawiki.org/wiki/Help:ChangeContentModel>.
* $wgRevisionCacheExpiry is now set to one week by default instead of being disabled.
* Magic links are now disabled by default, and can be re-enabled by modifying the value
  of $wgEnableMagicLinks. Their usage is discouraged, but if they are manually enabled,
  a tracking category will be added to help identify usage and make it easier to migrate
  away from. If you depend upon magic link functionality, it is requested that you comment
  on <https://www.mediawiki.org/wiki/Requests_for_comment/Future_of_magic_links> and
  explain your use case(s).
* New config variable $wgCSPFalsePositiveUrls to control what URLs to ignore
  in upcoming Content-Security-Policy feature's reporting.

=== New features in 1.28 ===
* User::isBot() method for checking if an account is a bot role account.
* Added a new 'slideshow' mode for galleries.
* Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  interact with API parsing.
* Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
  upload. Unlike 'UploadVerifyFile' it provides information about upload comment
  and the file description page, but does not run for uploads to stash.
* (T141604) Extensions can now provide a better error message when their
  maintenance scripts are run without the extension being installed.
* (T8948) Numeric sorting in categories is now supported by setting $wgCategoryCollation
  to 'uca-default-u-kn' or 'uca-<langcode>-u-kn'. If you can't use UCA collations,
  a 'numeric' collation is also available. If migrating from another
  collation, you will need to run the updateCollation.php maintenance script.
* Two new codes have been added to #time parser function: "xit" for days in current
  month, and "xiz" for days passed in the year, both in Iranian calendar.
* mw.Api has a new option, useUS, to use U+001F (Unit Separator) when
  appropriate for sending multi-valued parameters. This defaults to true when
  the mw.Api instance seems to be for the local wiki.
* After a client performs an action which alters a database that has replica databases,
  MediaWiki will wait for the replica databases to synchronize with the master database
  while it renders the HTML output. However, if the output is a redirect to another wiki
  on the wiki farm with a different domain, MediaWiki will instead alter the redirect
  URL to include a ?cpPosTime parameter that triggers the database synchronization when
  the URL is followed by the client. The same-domain case uses a new cpPosTime cookie.
* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
  'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
  'show' parameters to existing API query modules.

=== External library changes in 1.28 ===

==== Upgraded external libraries ====
* Updated es5-shim from v4.1.5 to v4.5.8
* Updated composer/semver from v1.4.1 to v1.4.2
* Updated wikimedia/php-session-serializer from v1.0.3 to v1.0.4

==== New external libraries ====
* Added wikimedia/scoped-callback v1.0.0
* Added wikimedia/wait-condition-loop v1.0.1

=== Bug fixes in 1.28 ===
* (T146496) action=history pages should return 404 HTTP error code if the page does not exist
* (T137264) SECURITY: XSS in unclosed internal links
* (T133147) SECURITY: Escape '<' and ']]>' in inline <style> blocks
* (T133147) SECURITY: Require login to preview user CSS pages
* (T132926) SECURITY: Do not allow undeleting a revision deleted file if it is
  the top file
* (T129738) SECURITY: Make $wgBlockDisablesLogin also restrict logged in
  permissions
* (T129738) SECURITY: Make blocks log users out if $wgBlockDisablesLogin is true
* (T139670) Move 'UserGetRights' call before application of
  Session::getAllowedUserRights()

=== Action API changes in 1.28 ===
* Added 'maxarticlesize' property to action=query&meta=siteinfo which contains
  the value of $wgMaxArticleSize.
* Property 'modulemessages' from action=parse&prop=modules was removed
  (deprecated since 1.26).
* The following response properties from action=login, deprecated in 1.27, are
  now removed: lgtoken, cookieprefix, sessionid. Clients should handle cookies
  to properly manage session state.
* Submitting the lgtoken and lgpassword parameters in the query string to
  action=login is now deprecated and outputs a warning. They should be submitted
  in the POST body instead.
* Submitting sensitive authentication request parameters to action=clientlogin,
  action=createaccount, action=linkaccount, and action=changeauthenticationdata
  in the query string is now deprecated and outputs a warning. They should be
  submitted in the POST body instead.
* (T141960) Multi-valued parameters may now be separated using U+001F (Unit Separator)
  instead of the pipe character. This will be useful if some of the multiple
  values need to contain pipes, e.g. for action=options.
* The API will now warn if input is not NFC-normalized Unicode or if it
  contains invalid characters.
* The 'normalized' list output by action=query and other modules that use
  ApiPageSet may contain entries where the 'from' value is percent-encoded as
  the raw value cannot be represented in a valid API response. These are
  indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
* (T28680) action=paraminfo can now return info about all submodules of a
  module without listing them all explicitly.
* (T146770) It is now possible to assert that the current user is a specific
  named user, using the 'assertuser' parameter.
* (T141963) Added a 'known' property when missing-but-known titles (e.g. from
  the 'TitleIsAlwaysKnown' hook) are output in various modules.

=== Action API internal changes in 1.28 ===
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  interact with ApiParse and ApiExpandTemplates.
* (T139565) SECURITY: API: Generate head items in the context of the given title
* (T115333) SECURITY: Check read permission when loading page content in ApiParse
* ApiBase::getResultData() was removed (deprecated since 1.25)
* ApiBase::makeHelpArrayToString() was removed (deprecated since 1.25)
* ApiBase::makeHelpMsgParameters() was removed (deprecated since 1.25)

* ApiFormatBase::setBufferResult() was removed (deprecated since 1.25)
* ApiFormatBase::setHelp() was removed (deprecated since 1.25)
* ApiFormatBase::setUnescapeAmps() was removed (deprecated since 1.25)
* ApiMain::makeHelpMsgHeader() was removed (deprecated since 1.25)
* ApiMain::reallyMakeHelpMsg() was removed (deprecated since 1.25)
* ApiMain::setHelp() was removed (deprecated since 1.25)
* ApiResult::beginContinuation() was removed (deprecated since 1.25)
* ApiResult::cleanUpUTF8() was removed (deprecated since 1.25)
* ApiResult::convertStatusToArray() was removed (deprecated since 1.25)

* ApiResult::enableSizeCheck() was removed (deprecated since 1.24)
* ApiResult::endContinuation() was removed (deprecated since 1.25)
* ApiResult::getData() was removed (deprecated since 1.25)
* ApiResult::getIsRawMode() was removed (deprecated since 1.25)

* ApiResult::setIndexedTagName_recursive() was removed (deprecated since 1.25)
* ApiResult::setMainForContinuation() was removed (deprecated since 1.25)
* ApiResult::setParsedLimit() was removed (deprecated since 1.25)
* ApiResult::setRawMode() was removed (deprecated since 1.25)
* ApiResult::size() was removed (deprecated since 1.25)
* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
  'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
  'show' parameters to existing API query modules. A query module can enable
  these hooks by passing an array for $hookData to ApiQueryBase::select() and
  by calling ApiQueryBase->processRow() before adding a row's data to the
  result.
* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
  their values out of the logs.

=== Languages updated in 1.28 ===

MediaWiki supports over 375 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as

  will no longer be automatically infused. You should call `OO.ui.infuse()`
  on them yourself from your JavaScript code.

* The command line options specific to parser tests have been removed from
  phpunit.php: --regex and --keep-uploads. Instead of --regex, use --filter.

== MediaWiki 1.27.5 ==
	
This is a security and maintenance release of the MediaWiki 1.27 branch.
