RELEASE-NOTES-1.31

   1 == MediaWiki 1.31 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.31 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.31 ===
   9 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
  10   a future version. The API is now considered to be stable, secure and
  11   essential.
  12 * $wgUsejQueryThree was removed, as it is now the default. This was documented as a
  13   temporary variable during the migration period, deprecated since 1.29.
  14 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
  15   possible for fallback images such as png.
  16 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does
  17   not have the right to mark things patrolled.
  18 * Wikis that contain imported revisions or CentralAuth global blocks should run
  19   maintenance/cleanupUsersWithNoId.php.
  20 * $wgResourceLoaderMinifierStatementsOnOwnLine and $wgResourceLoaderMinifierMaxLineLength
  21   were removed (deprecated since 1.27).
  22 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that are not
  23   using the latest version of the Referrer Policy specification.
  24 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a first step of
  25   migration to human-readable section IDs that will later result in 'html5' being the
  26   default mode.
  27 * CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
  28   as upstream is inactive and has no plans to move to PHP 7.
  29 * The old CategorizedRecentChanges feature, including its related configuration
  30   option $wgAllowCategorizedRecentChanges, has been removed.
  31 * (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported for
  32   performance reasons, and installations with this setting will now work as if it
  33   was configured with 'any'.
  34 * (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input, rather than
  35   being off by default. If you wish to disable HTML tidying entirely, set $wgTidyConfig
  36   to null; if you wish to use the old, deprecated Tidy external binary, both
  37   set $wgTidyConfig to null and also set $wgUseTidy to true.
  38 * $wgLogAutopatrol now defaults to false instead of true.
  39 * $wgValidateAllHtml was removed and will be ignored.
  40
  41 === New features in 1.31 ===
  42 * (T76554) User sub-pages named ….json are now protected in the same way that ….js
  43   and ….css pages are, so that configuration options can safely be placed there.
  44 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support
  45   joins with parentheses for grouping.
  46 * As a first pass in standardizing dialog boxes across the MediaWiki product,
  47   Html class now provides helper methods for messageBox, successBox, errorBox and
  48   warningBox generation.
  49 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
  50   a format like "iw>Example".
  51 * (T20209) Linker (used on history pages, log pages, and so on) will display
  52   usernames formed like "iw>Example" as interwiki links, as if by wikitext like
  53   [[iw:User:Example|iw>Example]].
  54 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
  55   users during an import.
  56 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
  57   the ParserOutput::getText() post-cache transformations.
  58 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
  59   initial page text for file uploads.
  60 * (T181651) The info page for File pages now displays the file's base-16 SHA1
  61   hash value in the table of basic information.
  62 * Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
  63   ParserOutput::getText() post-cache transformation. This may be disabled by
  64   passing 'deduplicateStyles' => false to that method.
  65 * The identity of the logged-in or IP "actor" for logged actions is being moved
  66   into a new actor table, with the rows in tables such as revision and logging
  67   referring to the actor ID instead of storing the user ID and name/IP in
  68   every row.
  69   * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
  70     can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
  71     soon as any necessary extensions are updated.
  72   * Most code accessing rows for logged actions from the database should use
  73     the relevant getQueryInfo() methods to get the information needed to build
  74     the SQL query. The ActorMigration class may also be used to get feature-flagged
  75     information needed to access actor-related fields during the migration
  76     period.
  77 * Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
  78   section without having to roll back the whole transaction.
  79 * Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
  80   and non-MySQL ::replace() and ::upsert() no longer roll back the whole
  81   transaction on failure.
  82 * (T189785) Added a monthly heartbeat ping to the pingback feature.
  83 * The CLI installer (maintenance/install.php) learned to detect and include
  84   extensions. Pass --with-extensions to enable that feature.
  85 * (T184791) rc_patrolled now has three states: "0" for unpatrolled,
  86   "1" for manually patrolled and "2" for autopatrolled actions.
  87 * Extensions can now set their type to "editor" if they provide an editor
  88   or enhance the editing experience.
  89 * Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces" property
  90   in extension.json. See
  91   <https://www.mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
  92   for more details and an example.

 169   locally or use a new interwiki-format username like "iw>Example".

 265 * The global function wfCountDown is now deprecated in favor of Maintenance::countDown.
 266 * Several methods for returning lists of fields to select from the database
 267   have been deprecated in favor of similar methods that also return the tables
 268   to select from and the join conditions for those tables.
 269   * Block::selectFields() → Block::getQueryInfo()
 270   * RecentChange::selectFields() → RecentChange::getQueryInfo()
 271   * ArchivedFile::selectFields() → ArchivedFile::getQueryInfo()

 281   * Revision::selectTextFields() → Revision::getQueryInfo( [ 'text' ] )
 282   * Revision::selectFields() → Revision::getQueryInfo()

 287 * Access to TitleValue class properties was deprecated, the relevant getters
 288   should be used instead.
 289 * DifferenceEngine::getDiffBodyCacheKey() is deprecated. Subclasses should
 290   override DifferenceEngine::getDiffBodyCacheKeyParams() instead.
 291 * Use of Maintenance::error( $err, $die ) to exit script was deprecated. Use
 292   Maintenance::fatalError() instead.
 293 * Passing a ParserOptions object to OutputPage::parserOptions() is deprecated.
 294 * The RevisionInsertComplete hook is now deprecated, use RevisionRecordInserted instead.
 295   RevisionInsertComplete is still called, but the second and third parameter will always be null.
 296   Hard deprecation is scheduled for 1.32.

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

 320   from the wikimedia/object-factory library should be used instead.
 321 * CommentStore::newKey is deprecated. Get an instance from MediaWikiServices instead.
 322 * The following CommentStore methods have had their signatures changed to introduce a $key parameter,
 323   usage of the methods on instances retrieved from CommentStore::newKey will remain unchanged but deprecated:
 324   * CommentStore::getFields
 325   * CommentStore::getJoin
 326   * CommentStore::getComment
 327   * CommentStore::getCommentLegacy
 328   * CommentStore::insert
 329   * CommentStore::insertWithTemplate
 330 * The following methods in Title have been renamed, and the old ones are deprecated:

 332   * Title::isCssOrJsPage – use ::isSiteConfigPage
 333   * Title::isCssJsSubpage – use ::isUserConfigPage
 334   * Title::isCssSubpage – use ::isUserCssConfigPage
 335   * Title::isJsSubpage – use ::isUserJsConfigPage
 336 * The following methods related to caching of half-parsed HTML were deprecated:
 337   * Parser::serializeHalfParsedText()
 338   * Parser::unserializeHalfParsedText()
 339   * Parser::isValidHalfParsedText()
 340   * StripState::getSubState()

 344   deprecated.
 345 * Wikimedia\Rdbms\SavepointPostgres is deprecated.
 346 * The DO_MAINTENANCE constant is deprecated. RUN_MAINTENANCE_IF_MAIN should be
 347   used instead.
 348 * The function wfShellWikiCmd() has been deprecated, use
 349   MediaWiki\Shell::makeScriptCommand().
 350
 351 === Other changes in 1.31 ===
 352 * Browser support for Internet Explorer 10 was lowered from Grade A to Grade C.
 353 * Browser support for Opera 12 and older was removed. Opera 15+ continues at Grade A.
 354 * Introducing multi-content-revision capability into the storage layer. For details,
 355   see <https://www.mediawiki.org/wiki/Requests_for_comment/Multi-Content_Revisions>.
 356 * The "free" CSS class is now only applied to unbracketed URLs in wikitext. Links
 357   written using square brackets will get the class "text" not "free".
 358 * RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
 359   wikitext table captions, wikitext table headings, wikitext table cells. HTML
 360   headings, HTML list items, HTML table captions, HTML table headings, HTML table cells
 361   will not have this trimming behavior.
 362
 363 == Compatibility ==
 364 MediaWiki 1.31 requires PHP 5.5.9 or later. Although HHVM 3.18.5 or later is supported,
 365 it is generally advised to use PHP 5.5.9 or later for long term support.
 366
 367 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 368 but support for them is somewhat less mature. There is experimental support for
 369 Oracle and Microsoft SQL Server.
 370
 371 The supported versions are:
 372
 373 * MySQL 5.0.3 or later
 374 * PostgreSQL 9.2 or later
 375 * SQLite 3.3.7 or later
 376 * Oracle 9.0.1 or later
 377 * Microsoft SQL Server 2005 (9.00.1399)
 378
 379 == Upgrading ==
 380 1.31 has several database changes since 1.30, and will not work without schema
 381 updates. Note that due to changes to some very large tables like the revision
 382 table, the schema update may take quite long (minutes on a medium sized site,
 383 many hours on a large site).
 384
 385 Don't forget to always back up your database before upgrading!
 386
 387 See the file UPGRADE for more detailed upgrade instructions, including
 388 important information when upgrading from versions prior to 1.11.
 389
 390 For notes on 1.30.x and older releases, see HISTORY.
