110 === Important pre-upgrade notes for 1.31 ===
111 * If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
112 schema changes, and cannot have downtime to run migrateArchiveText.php and
113 apply patch-drop-ar_text.sql manually, you'll have to apply a default value
114 to the ar_text and ar_flags columns of the archive table or make those
115 columns nullable before upgrading to MediaWiki 1.31.
116 maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
117 * The CologneBlue and Modern skins are no longer bundled with the tarball. You
118 will need to remove the wfLoadSkin() calls from your LocalSettings.php or
119 download them separately
120 (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).
121
122 === Configuration changes in 1.31 ===
123 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
124 a future version. The API is now considered to be stable, secure and
125 essential.
126 * $wgUsejQueryThree was removed, as it is now the default. This was documented
127 as a temporary variable during the migration period, deprecated since 1.29.
128 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
129 possible for fallback images such as png.
130 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
131 have the right to mark things patrolled.
132 * Wikis that contain imported revisions or CentralAuth global blocks should run
133 maintenance/cleanupUsersWithNoId.php.
134 * The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
135 $wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
136 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
137 are not using the latest version of the Referrer Policy specification.
138 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
139 first step of migration to human-readable section IDs that will later result
140 in 'html5' being the default mode.
141 * CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
142 as upstream is inactive and has no plans to move to PHP 7.
143 * The old CategorizedRecentChanges feature, including its related configuration
144 option $wgAllowCategorizedRecentChanges, has been removed.
145 * (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
146 for performance reasons, and installations with this setting will now work as
147 if it was configured with 'any'.
148 * (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
149 rather than being off by default. If you wish to disable HTML tidying
150 entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
151 Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
152 * $wgLogAutopatrol now defaults to false instead of true.
153 * $wgValidateAllHtml was removed and will be ignored.
154 * $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
155 1.25 release notes for more information.
156 * $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
157 framework that it enables. Some extensions mistakenly used this to check
158 whether any AJAX functionality at all should be enabled, further making this
159 problematic to retain.
160 * $wgDBmysql5 is now deprecated, and will be removed in a future version. It
161 has been marked as experimental ever since it was introduced.
162 * Fix $magicWords for the Sanskrit language
163
164 === New features in 1.31 ===
165 * (T76554) User sub-pages named ….json are now protected in the same way that
166 ….js and ….css pages are, so that configuration options can safely be placed
167 there.
168 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
169 with parentheses for grouping.
170 * As a first pass in standardizing dialog boxes across the MediaWiki product,
171 Html class now provides helper methods for messageBox, successBox, errorBox
172 and warningBox generation.
173 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
174 a format like "iw>Example".
175 * (T20209) Linker (used on history pages, log pages, and so on) will display
176 usernames formed like "iw>Example" as interwiki links, as if by wikitext like
177 [[iw:User:Example|iw>Example]].
178 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
179 users during an import.
180 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
181 the ParserOutput::getText() post-cache transformations.
182 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
183 initial page text for file uploads.
184 * (T181651) The info page for File pages now displays the file's base-16 SHA1
185 hash value in the table of basic information.
186 * Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
187 ParserOutput::getText() post-cache transformation. This may be disabled by
188 passing 'deduplicateStyles' => false to that method.
189 * The identity of the logged-in or IP "actor" for logged actions is being moved
190 into a new actor table, with the rows in tables such as revision and logging
191 referring to the actor ID instead of storing the user ID and name/IP in
192 every row.
193 * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
194 can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
195 soon as any necessary extensions are updated.
196 * Most code accessing rows for logged actions from the database should use
197 the relevant getQueryInfo() methods to get the information needed to build
198 the SQL query. The ActorMigration class may also be used to get feature
199 -flagged information needed to access actor-related fields during the
200 migration period.
201 * Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
202 section without having to roll back the whole transaction.
203 * Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
204 and non-MySQL ::replace() and ::upsert() no longer roll back the whole
205 transaction on failure.
206 * (T189785) Added a monthly heartbeat ping to the pingback feature.
207 * The CLI installer (maintenance/install.php) learned to detect and include
208 extensions. Pass --with-extensions to enable that feature.
209 * (T184791) rc_patrolled now has three states: "0" for unpatrolled,
210 "1" for manually patrolled and "2" for autopatrolled actions.
211 * Extensions can now set their type to "editor" if they provide an editor or
212 enhance the editing experience.
213 * Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
214 property in extension.json. See the documentation at
215 <https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
216 for more details and an example.
217 * (T19099) Tabs which link to pages that don't exist (like those to uncreated
218 discussion pages) now have a tooltip to indicate state, not just colour.
219
220 === External library changes in 1.31 ===
221 * pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
222 suggested to required. These packages now must be installed via composer
223 and not via PEAR itself.

259 === Action API changes in 1.31 ===
260 * (T185058) The 'name' value to tgprop for action=query&list=tags has been
261 removed. It has never made a difference in the output, the name was always
262 returned regardless.
263 * The 'watch' and 'unwatch' parameters for action=move have been removed. They
264 were deprecated and also accidentally nonfunctional since 1.17 in 2010. Use

378 for an implicit transaction also results in an exception. Previously these

408 * The Revision class was deprecated in favor of RevisionStore, BlobStore, and
409 RevisionRecord and its subclasses.
410 * The global function wfBCP47 is deprecated in favour of LanguageCode::bcp47.
411 * The global function wfCountDown is now deprecated in favor of
412 Maintenance::countDown.
413 * Several methods for returning lists of fields to select from the database
414 have been deprecated in favor of similar methods that also return the tables
415 to select from and the join conditions for those tables.
416 * Block::selectFields() → Block::getQueryInfo()
417 * RecentChange::selectFields() → RecentChange::getQueryInfo()
418 * ArchivedFile::selectFields() → ArchivedFile::getQueryInfo()

424 * Revision::userJoinCond() → Revision::getQueryInfo( [ 'user' ] )
425 * Revision::selectUserFields() → Revision::getQueryInfo( [ 'user' ] )
426 * Revision::pageJoinCond() → Revision::getQueryInfo( [ 'page' ] )
427 * Revision::selectPageFields() → Revision::getQueryInfo( [ 'page' ] )
428 * Revision::selectTextFields() → Revision::getQueryInfo( [ 'text' ] )
429 * Revision::selectFields() → Revision::getQueryInfo()

433 * Revision::setUserIdAndName() was deprecated.
434 * Access to TitleValue class properties was deprecated, the relevant getters
435 should be used instead.
436 * DifferenceEngine::getDiffBodyCacheKey() is deprecated. Subclasses should
437 override DifferenceEngine::getDiffBodyCacheKeyParams() instead.
438 * Use of Maintenance::error( $err, $die ) to exit script was deprecated. Use
439 Maintenance::fatalError() instead.
440 * Passing a ParserOptions object to OutputPage::parserOptions() is deprecated.
441 * The RevisionInsertComplete hook is now deprecated; use instead the hook
442 RevisionRecordInserted. RevisionInsertComplete is still called, but the second
443 and third parameter will always be null. Hard deprecation is scheduled for 1.32.
444 * The following methods that get and set ParserOutput state are deprecated.
445 Callers should use the new stateless $options parameter to

458 * QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
459 Setting template variables by reference allowed violating the principle of
460 data being immutable once added to the skin template. In practice, this method
461 was not being used for that. Rather, setRef() existed as memory optimisation
462 for PHP 4.
463 * QuickTemplate::setTranslator() and MediaWikiI18N::set() were deprecated in
464 favour of Skin::msg() parameters.
465 * MediaWikiI18N::translate() was deprecated in favour of Skin::msg() or
466 wfMessage().

468 'unwrap' transform to ParserOutput::getText() instead.

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

487 * Title::isCssJsSubpage – use ::isUserConfigPage
488 * Title::isCssSubpage – use ::isUserCssConfigPage
489 * Title::isJsSubpage – use ::isUserJsConfigPage
490 * The following methods related to caching of half-parsed HTML were deprecated:
491 * Parser::serializeHalfParsedText()
492 * Parser::unserializeHalfParsedText()
493 * Parser::isValidHalfParsedText()
494 * StripState::getSubState()
495 * StripState::merge()
496 * The DeferredStringifier class is deprecated, use Message::listParam() instead.
497 * The type string for the parameter $lang of DateFormatter::getInstance is
498 deprecated.
499 * Wikimedia\Rdbms\SavepointPostgres is deprecated.
500 * The DO_MAINTENANCE constant is deprecated. RUN_MAINTENANCE_IF_MAIN should be
501 used instead.

503 MediaWiki\Shell::makeScriptCommand().
504 * In the future, the hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend'
505 will be allowed to provide any HTMLForm object rather than PreferencesForm.
506
507 === Other changes in 1.31 ===
508 * Browser support for Internet Explorer 10 was lowered from Grade A to Grade C.
509 * Browser support for Opera 12 and older was dropped entirely. Opera 15+
510 continues at Grade A.
511 * Multi-content-revision capability was introduced into the storage layer. See
512 <https://mediawiki.org/wiki/Requests_for_comment/Multi-Content_Revisions>.
513 * The "free" CSS class is now only applied to unbracketed URLs in wikitext.
514 Links written using square brackets will get the class "text" not "free".
515 * RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
516 wikitext table captions, wikitext table headings, wikitext table cells. HTML
517 headings, HTML list items, HTML table captions, HTML table headings, HTML
518 table cells will not have this trimming behavior.
519
520 == Compatibility ==
521 MediaWiki 1.31 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
522 supported, it is generally advised to use PHP 7.0.13 or later for long term
523 support. MediaWiki requires that the mbstring, xml, ctype, json, iconv and
524 fileinfo PHP extensions are loaded to work.
525
526 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
527 but support for them is somewhat less mature. There is experimental support for
528 Oracle and Microsoft SQL Server.
529
530 The supported versions are:
531
532 * MySQL 5.5.8 or later
533 * PostgreSQL 9.2 or later
534 * SQLite 3.3.7 or later
535 * Oracle 9.0.1 or later
536 * Microsoft SQL Server 2005 (9.00.1399)
537
538 == Upgrading ==
539 1.31 has several database changes since 1.30, and will not work without schema
540 updates. Note that due to changes to some very large tables like the revision
541 table, the schema update may take quite long (minutes on a medium sized site,
542 many hours on a large site).
543
544 Don't forget to always back up your database before upgrading!
545
546 See the file UPGRADE for more detailed upgrade instructions, including
547 important information when upgrading from versions prior to 1.11.
