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. However some maintenance scripts (bitnami?) still may rely on "mysql".
    $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.

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.

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.

    (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.

        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::$mArticle and ::$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.

    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 release. For notifying the user of an event, the Notifications ("Echo") system should be used instead.

    (T165846) SECURITY: BotPassword login attempts weren't throttled

Compatibility

MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for HHVM 3.6.5 or later.

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 8.3 or later
    SQLite 3.3.7 or later
    Oracle 9.0.1 or later
    Microsoft SQL Server 2005 (9.00.1399)

Upgrading

1.30 has several database changes since 1.29, 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 a long time (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 1.29.x and older releases, see HISTORY.
