RELEASE-NOTES-1.33

   1 == MediaWiki 1.33 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.33 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.33 ===
   9
  10 ==== New configuration ====
  11 * $wgEnablePartialBlocks – This enables the Partial Blocks feature, which gives
  12   accounts with block permissions the ability to block users, IPs, and IP ranges
  13   from editing specific pages, while allowing them to edit the rest of the wiki.
  14
  15 ==== Changed configuration ====
  16 * Some external link searches will not work correctly until update.php (or
  17   refreshExternallinksIndex.php) is run. These include searches for links using
  18   IP addresses, internationalized domain names, and possibly mailto links.
  19 * (T193868) $wgChangeTagsSchemaMigrationStage — This temporary setting, added in
  20   MediaWiki 1.32, now defaults to MIGRATION_NEW instead of MIGRATION_WRITE_BOTH.
  21 * Special:ActiveUsers will no longer filter out users who became inactive since
  22   the last time the active users query cache was updated.
  23 * If you ran migrateActors.php using an older version of MediaWiki and want to
  24   run your wiki with $wgActorTableSchemaMigrationStage SCHEMA_COMPAT_READ_OLD,
  25   note that log_search rows needed to find revision deletions by target user
  26   were incorrectly deleted. See T215464 for details.
  27
  28 ==== Removed configuration ====
  29 * (T199334) $wgTagStatisticsNewTable — This temporary setting, added in
  30   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  31   will now always use the `change_tag_def` instead of the `change_tag` table.
  32 * MediaWiki now always tidies user output, and most related
  33   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  34   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  35   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  36   setting remains only for Remex experimental features or debugging.
  37 * $wgEnableParserCache, deprecated since 1.26, was removed.
  38   If disabling the parser cache is still desirable,
  39   set `$wgParserCacheType = CACHE_NONE;` instead.
  40 * $wgCommentTableSchemaMigrationStage has been removed. Extension code finding
  41   it unset should treat it as being MIGRATION_NEW.
  42 * $wgAuth – This old setting, deprecated in 1.27, has been removed as part of
  43   the removal of AuthPlugin.
  44
  45 === New features in 1.33 ===
  46 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  47   to be hidden on Special:UnusedCategories.
  48 * Add PasswordPolicy to check the password isn't in the large blacklist.
  49 * The AuthManagerLoginAuthenticateAudit hook has a new parameter for
  50   additional information about the authentication event.
  51 * TextContent::getText() was introduced as a replacement for
  52   Content::getNativeData() for text-based content models.
  53 * (T210814) SVGs are now by default displayed in wiki language on image
  54   pages.
  55 * (T214706) LinksUpdate::getAddedExternalLinks() and
  56   LinksUpdate::getRemovedExternalLinks() were introduced.
  57 * Argon2 password hashing is now available, can be enabled via
  58   $wgPasswordDefault = 'argon2'. It's designed to resist timing attacks
  59   (requires PHP 7.2+) and GPU hacking (7.3+).
  60 * Special:CreateAccount now warns the user if their chosen username has to be
  61   normalized.
  62 * (T205040) Multilingual images are now be displayed in the current parse
  63   language where available.
  64
  65 === External library changes in 1.33 ===

  67 ==== New external libraries ====
  68 * Added wikimedia/password-blacklist 0.1.4.
  69 * Added guzzlehttp/guzzle 6.3.3.
  70 * Added jakub-onderka/php-console-highlighter 0.3.2 explicitly (dev-only).

  88
  89 ==== Removed external libraries ====
  90
  91 === Bug fixes in 1.33 ===
  92 * (T164211) Special:UserRights could sometimes fail with a
  93   "conflict detected" error when there weren't any conflicts.
  94
  95 === Action API changes in 1.33 ===
  96 * (T198913) Added 'ApiOptions' hook.
  97 * The JSON formatversion=2 is no longer experimental.
  98 * Internal API errors (those with code beginning "internal_api_error") will
  99   include the exception class name in a data field named "errorclass".
 100   * Class names are not guaranteed to remain stable, and in particular database
 101     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
 102   * The code including an exception class name is deprecated. In the future,
 103     all internal errors will use code "internal_api_error".
 104 * (T212356) When using action=delete on pages with many revisions, the module
 105   may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
 106   deletion will be processed via the job queue.
 107 * action=setnotificationtimestamp will now update the watchlist asynchronously
 108   if entirewatchlist is set, so updates may not be visible immediately
 109 * Block info will be added to "blocked" errors from more modules.
 110 * (T216245) Autoblocks will now be spread by action=edit and action=move.
 111
 112 === Action API internal changes in 1.33 ===
 113 * A number of deprecated methods for API documentation, intended for overriding
 114   by extensions, are no longer called by MediaWiki, and will emit deprecation
 115   notices if your extension attempts to use them:
 116   * ApiBase::getDescription() (deprecated in 1.25)
 117   * ApiBase::getParamDescription() (deprecated in 1.25)
 118   * ApiBase::getExamples() (deprecated in 1.25)
 119   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 120   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 121   been removed, as their only use was to let extensions override values returned
 122   by getDescription() and getParamDescription(), respectively.
 123 * API error codes may only contain ASCII letters, numbers, underscore, and
 124   hyphen. Methods such as ApiBase::dieWithError() and
 125   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
 126   passed a bad code.
 127 * ApiBase::checkTitleUserPermissions() now takes an options array as its third
 128   parameter. Passing a User object or null is deprecated.
 129 * The api-feature-usage log channel now has log context. The text message is
 130   deprecated and will be removed in the future.
 131
 132 === Languages updated in 1.33 ===
 133 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 134 Below only new and removed languages are listed, as well as changes to languages
 135 because of Phabricator reports.
 136
 137 * (T203908) Added language support for Eastern Pwo (kjp).
 138 * (T213717) Fixed a translation error on Goan Konkani (gom-deva) translations
 139   for NS_TEMPLATE.
 140 * (T212221) Added $digitTransformTable for Santali (sat).
 141 * (T216479) Added language support for Saisiyat (xsy).
 142
 143 === Breaking changes in 1.33 ===
 144 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 145   Language. Other types are deprecated since 1.32.
 146 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 147   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 148   deprecated since 1.32.
 149 * Language::truncate(), deprecated in 1.31, has been removed.
 150 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 151   instead.
 152 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 153   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 154   use 'help', 'help-message', and 'help-messages'.
 155 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 156 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 157   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 158   Use the RESTBase v1 or Parsoid v3 API instead.
 159 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 160   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 161   has always been true at any rate.
 162 * Support for disabling tidy and external tidy implementations has been removed.
 163   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 164   used and no configuration is necessary.
 165 * A number of deprecated methods for API documentation, intended for overriding
 166   by extensions, are no longer called by MediaWiki, and will emit deprecation
 167   notices if your extension attempts to use them:
 168   * ApiBase::getDescription() (deprecated in 1.25)
 169   * ApiBase::getParamDescription() (deprecated in 1.25)
 170   * ApiBase::getExamples() (deprecated in 1.25)
 171   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 172   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 173   been removed, as their only use was to let extensions override values returned
 174   by getDescription() and getParamDescription(), respectively.
 175 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 176   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 177   the creation of AuthManager in 1.27, have been removed. This also means that
 178   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 179   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 180   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 181 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 182   use 'jquery.i18n'.
 183 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 184   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 185   respectively in a $wgExtensionMessagesFiles file.
 186 * The following methods of the Preferences class, deprecated in 1.31, have been
 187   removed:
 188   * getSaveBlacklist()

 213 * The 'mediawiki.api' module aliases, deprecated in 1.32, have been removed.
 214   Specifically: mediawiki.api.category, mediawiki.api.edit,
 215   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 216   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 217   mediawiki.api.messages, and mediawiki.api.rollback.
 218 * The 'jquery.byteLimit' module alias for 'jquery.lengthLimit',
 219   deprecated in 1.31, was removed.
 220 * Revision::fetchRevision(), deprecated in 1.28, was removed.
 221 * Class SquidUpdate, deprecated in 1.27, was removed.
 222 * Title->getSquidURLs(), deprecated in 1.27, was removed. Instead, use
 223   Title->getCdnUrls().
 224 * Title::escapeFragmentForURL(), deprecated in 1.30, was removed. Use
 225   Sanitizer::escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 226 * Title->canTalk(), deprecated in 1.30, was removed. Instead, use
 227   Title->canHaveTalkPage().
 228 * Title's methods for site and user page related to CSS and JS, deprecated in
 229   1.31, were removed:
 230   * Title->isCssOrJsPage() — Use Title->isSiteConfigPage()
 231   * Title->isCssJsSubpage() – Use Title->isUserConfigPage()

 235 * SiteSQLStore, deprecated in 1.27 and whose only method, ::newInstance(),
 236   would return the global SiteStore instance, has been removed. You can get to
 237   this via MediaWiki\MediaWikiServices::getInstance()->getSiteStore() directly.
 238 * Linker::formatSize, deprecated in 1.28, has been removed (with DummyLinker's).
 239   Instead, use Language->formatSize() with the relevant Language object.
 240 * Linker::formatTemplates, deprecated in 1.28, has been removed (along with the
 241   version in DummyLinker). You can use TemplatesOnThisPageFormatter directly.
 242 * EventRelayerGroup::singleton(), deprecated in 1.27, has been removed. You can
 243   use MediaWikiServices::getInstance()->getEventRelayerGroup() directly.
 244 * LinkCache->addLink(), deprecated in 1.27, has been removed. It is thought to
 245   be unused, and is distinct from OutputPage->addLink(), which remains.

 250 * SearchEngine::getNearMatchResultSet(), deprecated in 1.27, has been removed.
 251   You can use SearchEngine::getNearMatcher() instead.
 252 * EmailNotification::updateWatchlistTimestamp, deprecated in 1.27, has been
 253   removed. Instead, use WatchedItemStore::updateNotificationTimestamp directly.
 254 * User::getGroupName() and ::getGroupMember(), both deprecated in 1.29, have
 255   been removed. Instead, please use UserGroupMembership::getGroupName() and
 256   UserGroupMembership::getGroupMemberName().
 257 * Backwards compatibility for setting wgSessionsInObjectCache to false or using
 258   wgSessionHandler, both of which were deprecated in 1.27 with the introduction
 259   of SessionManager, has been removed.
 260 * SessionManager::autoCreateUser, deprecated in 1.27, has been removed. Use
 261   MediaWiki\Auth\AuthManager::autoCreateUser instead.
 262 * The mw.libs.jpegmeta property, deprecated in 1.31, was removed.

 276 * The 'jquery.hidpi' module, deprecated in 1.32, has been removed.
 277 * AuthPlugin and related code, deprecated in 1.27, has been removed. Extensions
 278   should instead use AuthManager. The following no longer exist:
 279   * The AuthPlugin class itself and the related AuthPluginUser class and i18n
 280   * The AuthPluginSetup and AuthPluginAutoCreate hooks
 281   * The transitional wrapper classes AuthPluginPrimaryAuthenticationProvider,
 282     AuthManagerAuthPlugin, and AuthManagerAuthPluginUser.
 283   * The $wgAuth configuration setting and its use in Setup.php and unit tests
 284 * (T217772) The 'wgAvailableSkins' mw.config key in JavaScript, was removed.
 285 * Language::markNoConversion, deprecated in 1.32, has been removed. Use
 286   LanguageConverter::markNoConversion instead.
 287 * BagOStuff::modifySimpleRelayEvent() method has been removed.
 288 * ParserOutput::getLegacyOptions, deprecated in 1.30, has been removed.
 289   Use ParserOutput::allCacheVaryingOptions instead.
 290 * CdnCacheUpdate::newSimplePurge, deprecated in 1.27, has been removed.
 291   Use CdnCacheUpdate::newFromTitles() instead.
 292
 293 === Deprecations in 1.33 ===
 294 * The configuration option $wgUseESI has been deprecated, and is expected
 295   to be removed in a future release.
 296 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 297   and is expected to be removed in a future release.
 298 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 299   introduced in MW 1.17, have been deprecated.  These fixes will always be
 300   applied for Arabic and Malayalam in the future.  Please enable these on
 301   your local wiki (if you have them explicitly set to false) and run
 302   maintenance/cleanupTitles.php to fix any existing page titles.
 303 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 304   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 305   This will help identify the issue if you added it to $wgAuthManagerConfig.
 306 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 307   domain ID as a key component and use makeGlobalKey().
 308 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 309   Title::getDBKey(), which doesn't vary case.
 310 * User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
 311   returns the same information in a more useful format.
 312 * For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
 313   as the $lang parameter was deprecated. The same applies to DummyLinker.
 314 * The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
 315   follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
 316   instead which blacklists 100,000 commonly used passwords.
 317 * (T208862) Action::requiresUnblock() is now called from
 318   Title::getUserPermissionsErrors() and Title::userCan(). Previously, the method
 319   was only called in Action::checkCanExecute(). Actions should ensure that their
 320   requiresUnblock() returns the proper result (the default is `true`).
 321 * (T211608) The MediaWiki\Services namespace has been renamed to
 322   Wikimedia\Services. The old name is still supported, but deprecated.
 323 * (T155582) Content::getNativeData has been deprecated. Please use model-
 324   specific getters, such as TextContent::getText().
 325 * The class WebInstallerOutput is now marked as @private.
 326 * (T209699) The jquery.async module has been deprecated. JavaScript code that
 327   needs asynchronous behaviour should use Promises.
 328 * Password::equals() is deprecated, use verify().
 329 * BaseTemplate::msgWiki() and QuickTemplate::msgWiki() will be removed. Use
 330   other means to fetch a properly escaped message string or Message object.
 331 * (T126091) The 'ResourceLoaderTestModules' hook, which lets you declare QUnit
 332   testing code for your JavaScript modules, is deprecated. Instead, you can now
 333   use the new extension registration key 'QUnitTestModule'.
 334 * (T213426) The jquery.throttle-debounce module has been deprecated. JavaScript
 335   code that needs this behaviour should use OO.ui.debounce/throttle.
 336 * The mw.language.specialCharacters property from the
 337   'mediawiki.language.specialCharacters' module has been deprecated.
 338   Use require( 'mediawiki.language.specialCharacters' ) instead.
 339 * ChangeTags::purgeTagUsageCache() has been deprecated, and is expected to be
 340   removed in a future release.
 341 * Passing a User object or null as the third parameter to
 342   ApiBase::checkTitleUserPermissions() has been deprecated. Pass an array
 343   [ 'user' => $user ] instead.
 344 * (T211578) Block::prevents is deprecated. Use Block::isEmailBlocked,
 345   Block::isCreateAccountBlocked and Block::isUsertalkEditAllowed to get and set
 346   block properties; use Block::appliesToRight and Block::appliesToUsertalk to
 347   check block behaviour.
 348 * The api-feature-usage log channel now has log context. The text message is
 349   deprecated and will be removed in the future.
 350
 351 === Other changes in 1.33 ===
 352 * (T201747) Html::openElement() warns if given an element name with a space
 353   in it.
 354 * The implementation of buildStringCast() in Wikimedia\Rdbms\Database has
 355   changed to explicitly cast. Subclasses relying on the base-class
 356   implementation should check whether they need to override it now.
 357 * BagOStuff::add is now abstract and must explicitly be defined in subclasses.
 358
 359 == Compatibility ==
 360 MediaWiki 1.33 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 361 supported, it is generally advised to use PHP 7.0.13 or later for long term
 362 support.
 363
 364 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 365 but support for them is somewhat less mature. There is experimental support for
 366 Oracle and Microsoft SQL Server.
 367
 368 The supported versions are:
 369
 370 * MySQL 5.5.8 or later
 371 * PostgreSQL 9.2 or later
 372 * SQLite 3.8.0 or later
 373 * Oracle 9.0.1 or later
 374 * Microsoft SQL Server 2005 (9.00.1399)
 375
 376 == Upgrading ==
 377 1.33 has several database changes since 1.32, and will not work without schema
 378 updates. Note that due to changes to some very large tables like the revision
 379 table, the schema update may take quite long (minutes on a medium sized site,
 380 many hours on a large site).
 381
 382 Don't forget to always back up your database before upgrading!
 383
 384 See the file UPGRADE for more detailed upgrade instructions, including
 385 important information when upgrading from versions prior to 1.11.
