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 * $wgMediaInTargetLanguage – whether multilingual images should be dispalyed in
  15   the current parse language where available.
  16
  17 ==== Changed configuration ====
  18 * Some external link searches will not work correctly until update.php (or
  19   refreshExternallinksIndex.php) is run. These include searches for links using
  20   IP addresses, internationalized domain names, and possibly mailto links.
  21 * (T193868) $wgChangeTagsSchemaMigrationStage — This temporary setting, added in
  22   MediaWiki 1.32, now defaults to MIGRATION_NEW instead of MIGRATION_WRITE_BOTH.
  23 * Special:ActiveUsers will no longer filter out users who became inactive since
  24   the last time the active users query cache was updated.
  25 * If you ran migrateActors.php using an older version of MediaWiki and want to
  26   run your wiki with $wgActorTableSchemaMigrationStage SCHEMA_COMPAT_READ_OLD,
  27   note that log_search rows needed to find revision deletions by target user
  28   were incorrectly deleted. See T215464 for details.
  29
  30 ==== Removed configuration ====
  31 * (T199334) $wgTagStatisticsNewTable — This temporary setting, added in
  32   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  33   will now always use the `change_tag_def` instead of the `change_tag` table.
  34 * MediaWiki now always tidies user output, and most related
  35   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  36   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  37   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  38   setting remains only for Remex experimental features or debugging.
  39 * $wgEnableParserCache, deprecated since 1.26, was removed.
  40   If disabling the parser cache is still desirable,
  41   set `$wgParserCacheType = CACHE_NONE;` instead.
  42 * $wgCommentTableSchemaMigrationStage has been removed. Extension code finding
  43   it unset should treat it as being MIGRATION_NEW.
  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
  61 === External library changes in 1.33 ===
  62
  63 ==== New external libraries ====
  64 * Added wikimedia/password-blacklist 0.1.4.
  65 * Added guzzlehttp/guzzle 6.3.3.
  66 * Added jakub-onderka/php-console-highlighter 0.3.2 explicitly (dev-only).

  83
  84 ==== Removed external libraries ====
  85
  86 === Bug fixes in 1.33 ===
  87 * (T164211) Special:UserRights could sometimes fail with a
  88   "conflict detected" error when there weren't any conflicts.
  89 * (T215566) Unable to determine if the database exists
  90   during a fresh installation.
  91
  92 === Action API changes in 1.33 ===
  93 * (T198913) Added 'ApiOptions' hook.
  94 * The JSON formatversion=2 is no longer experimental.
  95 * Internal API errors (those with code beginning "internal_api_error") will
  96   include the exception class name in a data field named "errorclass".
  97   * Class names are not guaranteed to remain stable, and in particular database
  98     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  99   * The code including an exception class name is deprecated. In the future,
 100     all internal errors will use code "internal_api_error".
 101 * (T212356) When using action=delete on pages with many revisions, the module
 102   may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
 103   deletion will be processed via the job queue.
 104 * action=setnotificationtimestamp will now update the watchlist asynchronously
 105   if entirewatchlist is set, so updates may not be visible immediately
 106 * Block info will be added to "blocked" errors from more modules.
 107 * (T216245) Autoblocks will now be spread by action=edit and action=move.
 108
 109 === Action API internal changes in 1.33 ===
 110 * A number of deprecated methods for API documentation, intended for overriding
 111   by extensions, are no longer called by MediaWiki, and will emit deprecation
 112   notices if your extension attempts to use them:
 113   * ApiBase::getDescription() (deprecated in 1.25)
 114   * ApiBase::getParamDescription() (deprecated in 1.25)
 115   * ApiBase::getExamples() (deprecated in 1.25)
 116   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 117   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 118   been removed, as their only use was to let extensions override values returned
 119   by getDescription() and getParamDescription(), respectively.
 120 * API error codes may only contain ASCII letters, numbers, underscore, and
 121   hyphen. Methods such as ApiBase::dieWithError() and
 122   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
 123   passed a bad code.
 124 * ApiBase::checkTitleUserPermissions() now takes an options array as its third
 125   parameter. Passing a User object or null is deprecated.
 126
 127 === Languages updated in 1.33 ===
 128 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 129 Below only new and removed languages are listed, as well as changes to languages
 130 because of Phabricator reports.
 131
 132 * (T203908) Added language support for Eastern Pwo (kjp).
 133 * (T213717) Fixed a translation error on Goan Konkani (gom-deva) translations
 134   for NS_TEMPLATE.
 135 * (T212221) Added $digitTransformTable for Santali (sat).
 136 * (T216479) Added language support for Saisiyat (xsy).
 137
 138 === Breaking changes in 1.33 ===
 139 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 140   Language. Other types are deprecated since 1.32.
 141 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 142   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 143   deprecated since 1.32.
 144 * Language::truncate(), deprecated in 1.31, has been removed.
 145 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 146   instead.
 147 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 148   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 149   use 'help', 'help-message', and 'help-messages'.
 150 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 151 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 152   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 153   Use the RESTBase v1 or Parsoid v3 API instead.
 154 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 155   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 156   has always been true at any rate.
 157 * Support for disabling tidy and external tidy implementations has been removed.
 158   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 159   used and no configuration is necessary.
 160 * A number of deprecated methods for API documentation, intended for overriding
 161   by extensions, are no longer called by MediaWiki, and will emit deprecation
 162   notices if your extension attempts to use them:
 163   * ApiBase::getDescription() (deprecated in 1.25)
 164   * ApiBase::getParamDescription() (deprecated in 1.25)
 165   * ApiBase::getExamples() (deprecated in 1.25)
 166   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 167   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 168   been removed, as their only use was to let extensions override values returned
 169   by getDescription() and getParamDescription(), respectively.
 170 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 171   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 172   the creation of AuthManager in 1.27, have been removed. This also means that
 173   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 174   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 175   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 176 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 177   use 'jquery.i18n'.
 178 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 179   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 180   respectively in a $wgExtensionMessagesFiles file.
 181 * The following methods of the Preferences class, deprecated in 1.31, have been
 182   removed:
 183   * getSaveBlacklist()
 184   * loadPreferenceValues()
 185   * getOptionFromUser()
 186   * profilePreferences()
 187   * skinPreferences()

 196   * generateSkinOptions()
 197   * getDateOptions()
 198   * getImageSizes()
 199   * getThumbSizes()
 200   * validateSignature()
 201   * cleanSignature()
 202   * getTimezoneOptions()
 203   * filterIntval()
 204   * filterTimezoneInput()
 205   * getTimeZoneList()
 206 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 207 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 208 * The 'mediawiki.api' module aliases, deprecated in 1.32, have been removed.
 209   Specifically: mediawiki.api.category, mediawiki.api.edit,
 210   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 211   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 212   mediawiki.api.messages, and mediawiki.api.rollback.
 213 * The 'jquery.byteLimit' module alias for 'jquery.lengthLimit',
 214   deprecated in 1.31, was removed.
 215 * Revision::fetchRevision(), deprecated in 1.28, was removed.
 216 * Class SquidUpdate, deprecated in 1.27, was removed.
 217 * Title->getSquidURLs(), deprecated in 1.27, was removed. Instead, use
 218   Title->getCdnUrls().
 219 * Title::escapeFragmentForURL(), deprecated in 1.30, was removed. Use
 220   Sanitizer::escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 221 * Title->canTalk(), deprecated in 1.30, was removed. Instead, use
 222   Title->canHaveTalkPage().
 223 * Title's methods for site and user page related to CSS and JS, deprecated in
 224   1.31, were removed:
 225   * Title->isCssOrJsPage() — Use Title->isSiteConfigPage()
 226   * Title->isCssJsSubpage() – Use Title->isUserConfigPage()
 227   * Title->getSkinFromCssJsSubpage() – Use Title->getSkinFromConfigSubpage()
 228   * Title->isCssSubpage() – Use Title->isUserCssConfigPage()
 229   * Title->isJsSubpage() – Use Title->isUserJsConfigPage()
 230 * SiteSQLStore, deprecated in 1.27 and whose only method, ::newInstance(),
 231   would return the global SiteStore instance, has been removed. You can get to
 232   this via MediaWiki\MediaWikiServices::getInstance()->getSiteStore() directly.
 233 * Linker::formatSize, deprecated in 1.28, has been removed (with DummyLinker's).
 234   Instead, use Language->formatSize() with the relevant Language object.
 235 * Linker::formatTemplates, deprecated in 1.28, has been removed (along with the
 236   version in DummyLinker). You can use TemplatesOnThisPageFormatter directly.
 237 * EventRelayerGroup::singleton(), deprecated in 1.27, has been removed. You can
 238   use MediaWikiServices::getInstance()->getEventRelayerGroup() directly.
 239 * LinkCache->addLink(), deprecated in 1.27, has been removed. It is thought to
 240   be unused, and is distinct from OutputPage->addLink(), which remains.
 241 * JsonContent->getJsonData(), deprecated in 1.25, has been removed. Instead, use
 242   JsonContent->getData().
 243 * MWExceptionHandler::getLogId(), deprecated in 1.27, has been removed, as the
 244   exception ID is the same as the request ID, from WebRequest::getRequestId().
 245 * SearchEngine::getNearMatchResultSet(), deprecated in 1.27, has been removed.
 246   You can use SearchEngine::getNearMatcher() instead.
 247 * EmailNotification::updateWatchlistTimestamp, deprecated in 1.27, has been
 248   removed. Instead, use WatchedItemStore::updateNotificationTimestamp directly.
 249 * User::getGroupName() and ::getGroupMember(), both deprecated in 1.29, have
 250   been removed. Instead, please use UserGroupMembership::getGroupName() and
 251   UserGroupMembership::getGroupMemberName().
 252 * Backwards compatibility for setting wgSessionsInObjectCache to false or using
 253   wgSessionHandler, both of which were deprecated in 1.27 with the introduction
 254   of SessionManager, has been removed.
 255 * SessionManager::autoCreateUser, deprecated in 1.27, has been removed. Use
 256   MediaWiki\Auth\AuthManager::autoCreateUser instead.
 257 * The mw.libs.jpegmeta property, deprecated in 1.31, was removed.
 258   Use require( 'mediawiki.libs.jpegmeta' ) instead.
 259 * The mw.user.stickyRandomId() method, deprecated in 1.32, was removed.
 260   Use mw.user.getPageviewToken() instead.
 261 * Removed deprecated class property WikiRevision::$importer.
 262 * ResourceLoaderFileModule::readStyleFiles() now requires its $context
 263   parameter.
 264 * The ChangeList::insertArticleLink() method, that was deprecated in 1.27, has
 265   been removed.
 266 * MessageBlobStore::__construct() now requires its $rl parameter.
 267
 268 === Deprecations in 1.33 ===
 269 * The configuration option $wgUseESI has been deprecated, and is expected
 270   to be removed in a future release.
 271 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 272   and is expected to be removed in a future release.
 273 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 274   introduced in MW 1.17, have been deprecated.  These fixes will always be
 275   applied for Arabic and Malayalam in the future.  Please enable these on
 276   your local wiki (if you have them explicitly set to false) and run
 277   maintenance/cleanupTitles.php to fix any existing page titles.
 278 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 279   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 280   This will help identify the issue if you added it to $wgAuthManagerConfig.
 281 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 282   domain ID as a key component and use makeGlobalKey().
 283 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 284   Title::getDBKey(), which doesn't vary case.
 285 * User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
 286   returns the same information in a more useful format.
 287 * For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
 288   as the $lang parameter was deprecated. The same applies to DummyLinker.
 289 * The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
 290   follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
 291   instead which blacklists 100,000 commonly used passwords.
 292 * (T208862) Action::requiresUnblock() is now called from
 293   Title::getUserPermissionsErrors() and Title::userCan(). Previously, the method
 294   was only called in Action::checkCanExecute(). Actions should ensure that their
 295   requiresUnblock() returns the proper result (the default is `true`).
 296 * (T211608) The MediaWiki\Services namespace has been renamed to
 297   Wikimedia\Services. The old name is still supported, but deprecated.
 298 * (T155582) Content::getNativeData has been deprecated. Please use model-
 299   specific getters, such as TextContent::getText().
 300 * The class WebInstallerOutput is now marked as @private.
 301 * (T209699) The jquery.async module has been deprecated. JavaScript code that
 302   needs asynchronous behaviour should use Promises.
 303 * Password::equals() is deprecated, use verify().
 304 * BaseTemplate::msgWiki() and QuickTemplate::msgWiki() will be removed. Use
 305   other means to fetch a properly escaped message string or Message object.
 306 * (T126091) The 'ResourceLoaderTestModules' hook, which lets you declare QUnit
 307   testing code for your JavaScript modules, is deprecated. Instead, you can now
 308   use the new extension registration key 'QUnitTestModule'.
 309 * (T213426) The jquery.throttle-debounce module has been deprecated. JavaScript
 310   code that needs this behaviour should use OO.ui.debounce/throttle.
 311 * The mw.language.specialCharacters property from the
 312   'mediawiki.language.specialCharacters' module has been deprecated.
 313   Use require( 'mediawiki.language.specialCharacters' ) instead.
 314 * ChangeTags::purgeTagUsageCache() has been deprecated, and is expected to be
 315   removed in a future release.
 316 * Passing a User object or null as the third parameter to
 317   ApiBase::checkTitleUserPermissions() has been deprecated. Pass an array
 318   [ 'user' => $user ] instead.
 319
 320 === Other changes in 1.33 ===
 321 * (T201747) Html::openElement() warns if given an element name with a space
 322   in it.
 323 * The implementation of buildStringCast() in Wikimedia\Rdbms\Database has
 324   changed to explicitly cast. Subclasses relying on the base-class
 325   implementation should check whether they need to override it now.
 326
 327 == Compatibility ==
 328 MediaWiki 1.33 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 329 supported, it is generally advised to use PHP 7.0.13 or later for long term
 330 support.
 331
 332 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 333 but support for them is somewhat less mature. There is experimental support for
 334 Oracle and Microsoft SQL Server.
 335
 336 The supported versions are:
 337
 338 * MySQL 5.5.8 or later
 339 * PostgreSQL 9.2 or later
 340 * SQLite 3.3.7 or later
 341 * Oracle 9.0.1 or later
 342 * Microsoft SQL Server 2005 (9.00.1399)
 343
 344 == Upgrading ==
 345 1.33 has several database changes since 1.32, and will not work without schema
 346 updates. Note that due to changes to some very large tables like the revision
 347 table, the schema update may take quite long (minutes on a medium sized site,
 348 many hours on a large site).
 349
 350 Don't forget to always back up your database before upgrading!
 351
 352 See the file UPGRADE for more detailed upgrade instructions, including
 353 important information when upgrading from versions prior to 1.11.
 354
 355 For notes on 1.32.x and older releases, see HISTORY.
 356
 357 == Online documentation ==
 358 Documentation for both end-users and site administrators is available on
 359 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 360 for pages that explicitly state that their contents are in the public domain):
 361
 362        https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation
 363
 364 == Mailing list ==
 365 A mailing list is available for MediaWiki user support and discussion:
 366
 367        https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 368
 369 A low-traffic announcements-only list is also available:
 370
 371        https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 372
 373 It's highly recommended that you sign up for one of these lists if you're
 374 going to run a public MediaWiki, so you can be notified of security fixes.
 375
 376 == IRC help ==
 377 There's usually someone online in #mediawiki on irc.freenode.net.
