+
+== MediaWiki 1.31.0 ==
+
+=== Changes since MediaWiki 1.31.0-rc.2 ===
+* (T195783) Initialize PSR-4 namespaces at same stage as normal autoloader.
+* (T196092) Hide MySQL binary/utf-8 charset option in the installer.
+* (T196185) Don't allow setting $wgDBmysql5 in the installer.
+* (T196125) php-memcached 3.0 (provided with PHP 7.0) is now supported.
+* (T182366) UploadBase::checkXMLEncodingMissmatch() now works on PHP 7.1+
+* (T118683) Fix exception from &$user deref on HHVM in the TitleMoveComplete hook.
+* (T196672) The mtime of extension.json files is now able to be zero
+* (T180403) Validate $length in padleft/padright parser functions.
+* (T143790) Make $wgEmailConfirmToEdit only affect edit actions.
+
+=== Changes since MediaWiki 1.31.0-rc.0 ===
+* (T33223) Drop archive.ar_text and ar_flags.
+* Add default edit rate limit of 90 edits/minute for all users.
+* (T187645) Use codepoint as tiebreaker when getting first-letters in
+ IcuCollation.
+* (T191947) Don't shell during the installer if shelling out is disabled.
+* (T194319) Improve duplicate config setting exception as part of extension
+ registration.
+* (T195211) Don't require trailing slash in PSR-4 autoloader directory.
+* (T186565) Fix PHP Notice from `ob_end_flush()` in `FileRepo::streamFile()`.
+* 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.
+
+=== 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.
+
+=== External library changes in 1.31 ===
+* pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
+ suggested to required. These packages now must be installed via composer
+ and not via PEAR itself.

+ removed. It has never made a difference in the output, the name was always
+ returned regardless.
+* The 'watch' and 'unwatch' parameters for action=move have been removed. They

+ 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::getCacheFields() with a prefix no longer works
+ * LocalFile::getLazyCacheFields() with a prefix no longer works
+ * OldLocalFile::selectFields() → OldLocalFile::getQueryInfo()
+ * RecentChange::selectFields() → RecentChange::getQueryInfo()

+ * WikiPage::selectFields() → WikiPage::getQueryInfo()
+* Revision::setUserIdAndName() was deprecated.
+* Access to TitleValue class properties was deprecated, the relevant getters
+ 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.
+ Callers should use the new stateless $options parameter to
+ ParserOutput::getText() instead.
+ * ParserOptions::getEditSection()
+ * ParserOptions::setEditSection()
+ * ParserOutput::getEditSectionTokens()
+ * ParserOutput::setEditSectionTokens()
+ * ParserOutput::getTOCEnabled()
+ * ParserOutput::setTOCEnabled()
+ * OutputPage::enableSectionEditLinks()
+ * OutputPage::sectionEditLinksEnabled()
+ * The public ParserOutput state fields $mTOCEnabled and $mEditSectionTokens
+ 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
+ wfMessage().

+ 'unwrap' transform to ParserOutput::getText() instead.
+* \ObjectFactory (no namespace) is deprecated, the namespaced class
+ \Wikimedia\ObjectFactory from the wikimedia/object-factory library should be
+ used instead.
+* CommentStore::newKey is deprecated. Instead, get an instance from
+ MediaWikiServices.

+ 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()
+* The DeferredStringifier class is deprecated, use Message::listParam() instead.
+* The type string for the parameter $lang of DateFormatter::getInstance is
+ deprecated.
+* Wikimedia\Rdbms\SavepointPostgres is deprecated.
+* The DO_MAINTENANCE constant is deprecated. RUN_MAINTENANCE_IF_MAIN should be
+ used instead.
+* The function wfShellWikiCmd() has been deprecated, use
+ MediaWiki\Shell::makeScriptCommand().
+* In the future, the hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend'
+ 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.
+* 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.
+
+== Compatibility ==
+MediaWiki 1.31 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
+supported, it is generally advised to use PHP 7.0.0 or later for long term
+support.
+
+MySQL/MariaDB 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:
+
+* MySQL 5.5.8 or later
+* PostgreSQL 9.2 or later
+* SQLite 3.3.7 or later
+* Oracle 9.0.1 or later
+* Microsoft SQL Server 2005 (9.00.1399)
+
+== Upgrading ==
+1.31 has several database changes since 1.30, 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).
+
+Don't forget to always back up your database before upgrading!
+
+See the file UPGRADE for more detailed upgrade instructions, including
+important information when upgrading from versions prior to 1.11.
+
+For notes on 1.30.x and older releases, see HISTORY.
+
+== Online documentation ==
+Documentation for both end-users and site administrators is available on
+MediaWiki.org, and is covered under the GNU Free Documentation License (except
+for pages that explicitly state that their contents are in the public domain):
+
+ https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation
+
+== Mailing list ==
+A mailing list is available for MediaWiki user support and discussion:
+
+ https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
+
+A low-traffic announcements-only list is also available:
+
+ https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
+
+It's highly recommended that you sign up for one of these lists if you're
+going to run a public MediaWiki, so you can be notified of security fixes.

+
+=== 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.

+ 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',

+ 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: skr (Saraiki, سرائیکی)
+* 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.
+* File::getStreamHeaders() was deprecated.
+* MediaHandler::getStreamHeaders() was deprecated.
+* Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be

+* 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.

+ 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.

+ 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

+ 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.

+* 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

+ user object. Using the method without the second argument is deprecated.
+* (T67297) Browsers that don't support Unicode will have their edits rejected.
