60 === Important pre-upgrade notes for 1.31 ===
61 * If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
62 schema changes, and cannot have downtime to run migrateArchiveText.php and
63 apply patch-drop-ar_text.sql manually, you'll have to apply a default value
64 to the ar_text and ar_flags columns of the archive table or make those
65 columns nullable before upgrading to MediaWiki 1.31.
66 maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
67 * The CologneBlue and Modern skins are no longer bundled with the tarball. You
68 will need to remove the wfLoadSkin() calls from your LocalSettings.php or
69 download them separately
70 (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).
72 === Configuration changes in 1.31 ===
73 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
74 a future version. The API is now considered to be stable, secure and
76 * $wgUsejQueryThree was removed, as it is now the default. This was documented
77 as a temporary variable during the migration period, deprecated since 1.29.
78 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
79 possible for fallback images such as png.
80 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
81 have the right to mark things patrolled.
82 * Wikis that contain imported revisions or CentralAuth global blocks should run
83 maintenance/cleanupUsersWithNoId.php.
84 * The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
85 $wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
86 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
87 are not using the latest version of the Referrer Policy specification.
88 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
89 first step of migration to human-readable section IDs that will later result
90 in 'html5' being the default mode.
91 * CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
92 as upstream is inactive and has no plans to move to PHP 7.
93 * The old CategorizedRecentChanges feature, including its related configuration
94 option $wgAllowCategorizedRecentChanges, has been removed.
95 * (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
96 for performance reasons, and installations with this setting will now work as
97 if it was configured with 'any'.
98 * (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
99 rather than being off by default. If you wish to disable HTML tidying
100 entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
101 Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
102 * $wgLogAutopatrol now defaults to false instead of true.
103 * $wgValidateAllHtml was removed and will be ignored.
104 * $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
105 1.25 release notes for more information.
106 * $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
107 framework that it enables. Some extensions mistakenly used this to check
108 whether any AJAX functionality at all should be enabled, further making this
109 problematic to retain.
110 * $wgDBmysql5 is now deprecated, and will be removed in a future version. It
111 has been marked as experimental ever since it was introduced.
113 === New features in 1.31 ===
114 * (T76554) User sub-pages named ….json are now protected in the same way that
115 ….js and ….css pages are, so that configuration options can safely be placed
117 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
118 with parentheses for grouping.
119 * As a first pass in standardizing dialog boxes across the MediaWiki product,
120 Html class now provides helper methods for messageBox, successBox, errorBox
121 and warningBox generation.
122 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
123 a format like "iw>Example".
124 * (T20209) Linker (used on history pages, log pages, and so on) will display
125 usernames formed like "iw>Example" as interwiki links, as if by wikitext like
126 [[iw:User:Example|iw>Example]].
127 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
128 users during an import.
129 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
130 the ParserOutput::getText() post-cache transformations.
131 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
132 initial page text for file uploads.
133 * (T181651) The info page for File pages now displays the file's base-16 SHA1
134 hash value in the table of basic information.
135 * Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
136 ParserOutput::getText() post-cache transformation. This may be disabled by
137 passing 'deduplicateStyles' => false to that method.
138 * The identity of the logged-in or IP "actor" for logged actions is being moved
139 into a new actor table, with the rows in tables such as revision and logging
140 referring to the actor ID instead of storing the user ID and name/IP in
142 * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
143 can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
144 soon as any necessary extensions are updated.
145 * Most code accessing rows for logged actions from the database should use
146 the relevant getQueryInfo() methods to get the information needed to build
147 the SQL query. The ActorMigration class may also be used to get feature
148 -flagged information needed to access actor-related fields during the
150 * Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
151 section without having to roll back the whole transaction.
152 * Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
153 and non-MySQL ::replace() and ::upsert() no longer roll back the whole
154 transaction on failure.
155 * (T189785) Added a monthly heartbeat ping to the pingback feature.
156 * The CLI installer (maintenance/install.php) learned to detect and include
157 extensions. Pass --with-extensions to enable that feature.
158 * (T184791) rc_patrolled now has three states: "0" for unpatrolled,
159 "1" for manually patrolled and "2" for autopatrolled actions.
160 * Extensions can now set their type to "editor" if they provide an editor or
161 enhance the editing experience.
162 * Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
163 property in extension.json. See the documentation at
164 <https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
165 for more details and an example.
166 * (T19099) Tabs which link to pages that don't exist (like those to uncreated
167 discussion pages) now have a tooltip to indicate state, not just colour.
169 === External library changes in 1.31 ===
170 * pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
171 suggested to required. These packages now must be installed via composer

366 * RecentChange::selectFields() → RecentChange::getQueryInfo()
367 * ArchivedFile::selectFields() → ArchivedFile::getQueryInfo()

383 * Access to TitleValue class properties was deprecated, the relevant getters
384 should be used instead.
385 * DifferenceEngine::getDiffBodyCacheKey() is deprecated. Subclasses should
386 override DifferenceEngine::getDiffBodyCacheKeyParams() instead.
387 * Use of Maintenance::error( $err, $die ) to exit script was deprecated. Use
388 Maintenance::fatalError() instead.
389 * Passing a ParserOptions object to OutputPage::parserOptions() is deprecated.
390 * The RevisionInsertComplete hook is now deprecated; use instead the hook
391 RevisionRecordInserted. RevisionInsertComplete is still called, but the second
392 and third parameter will always be null. Hard deprecation is scheduled for 1.32.

406 * License::getLicenses has been deprecated; use License::getLines instead.
407 * QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
408 Setting template variables by reference allowed violating the principle of

412 * QuickTemplate::setTranslator() and MediaWikiI18N::set() were deprecated in
413 favour of Skin::msg() parameters.
414 * MediaWikiI18N::translate() was deprecated in favour of Skin::msg() or

487 1.31 has several database changes since 1.30, and will not work without schema
488 updates. Note that due to changes to some very large tables like the revision
489 table, the schema update may take quite long (minutes on a medium sized site,
490 many hours on a large site).
492 Don't forget to always back up your database before upgrading!
494 See the file UPGRADE for more detailed upgrade instructions, including
495 important information when upgrading from versions prior to 1.11.
