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
  26 ==== Removed configuration ====
  27 * (T199334) $wgTagStatisticsNewTable — This temporary setting, added in
  28   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  29   will now always use the `change_tag_def` instead of the `change_tag` table.
  30 * MediaWiki now always tidies user output, and most related
  31   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  32   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  33   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  34   setting remains only for Remex experimental features or debugging.
  35 * $wgEnableParserCache, deprecated since 1.26, was removed.
  36   If disabling the parser cache is still desirable,
  37   set `$wgParserCacheType = CACHE_NONE;` instead.
  38 * $wgCommentTableSchemaMigrationStage has been removed. Extension code finding
  39   it unset should treat it as being MIGRATION_NEW.
  40
  41 === New features in 1.33 ===
  42 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  43   to be hidden on Special:UnusedCategories.
  44 * Add PasswordPolicy to check the password isn't in the large blacklist.
  45 * The AuthManagerLoginAuthenticateAudit hook has a new parameter for
  46   additional information about the authentication event.
  47 * TextContent::getText() was introduced as a replacement for
  48   Content::getNativeData() for text-based content models.
  49 * (T210814) SVGs are now by default displayed in wiki language on image
  50   pages.
  51 * (T214706) LinksUpdate::getAddedExternalLinks() and
  52   LinksUpdate::getRemovedExternalLinks() were introduced.
  53
  54 === External library changes in 1.33 ===
  55
  56 ==== New external libraries ====
  57 * Added wikimedia/password-blacklist 0.1.4.
  58 * Added guzzlehttp/guzzle 6.3.3.
  59 * Added jakub-onderka/php-console-highlighter 0.3.2 explicitly (dev-only).

  76
  77 ==== Removed external libraries ====
  78
  79 === Bug fixes in 1.33 ===
  80 * (T164211) Special:UserRights could sometimes fail with a
  81   "conflict detected" error when there weren't any conflicts.
  82 * (T215566) Unable to determine if the database exists
  83   during a fresh installation.
  84
  85 === Action API changes in 1.33 ===
  86 * (T198913) Added 'ApiOptions' hook.
  87 * The JSON formatversion=2 is no longer experimental.
  88 * Internal API errors (those with code beginning "internal_api_error") will
  89   include the exception class name in a data field named "errorclass".
  90   * Class names are not guaranteed to remain stable, and in particular database
  91     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  92   * The code including an exception class name is deprecated. In the future,
  93     all internal errors will use code "internal_api_error".
  94 * (T212356) When using action=delete on pages with many revisions, the module
  95   may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
  96   deletion will be processed via the job queue.
  97 * action=setnotificationtimestamp will now update the watchlist asynchronously
  98   if entirewatchlist is set, so updates may not be visible immediately
  99
 100 === Action API internal changes in 1.33 ===
 101 * A number of deprecated methods for API documentation, intended for overriding
 102   by extensions, are no longer called by MediaWiki, and will emit deprecation
 103   notices if your extension attempts to use them:
 104   * ApiBase::getDescription() (deprecated in 1.25)
 105   * ApiBase::getParamDescription() (deprecated in 1.25)
 106   * ApiBase::getExamples() (deprecated in 1.25)
 107   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 108   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 109   been removed, as their only use was to let extensions override values returned
 110   by getDescription() and getParamDescription(), respectively.
 111 * API error codes may only contain ASCII letters, numbers, underscore, and
 112   hyphen. Methods such as ApiBase::dieWithError() and
 113   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
 114   passed a bad code.
 115
 116 === Languages updated in 1.33 ===
 117 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 118 Below only new and removed languages are listed, as well as changes to languages
 119 because of Phabricator reports.
 120
 121 * (T203908) Added language support for Eastern Pwo (kjp).
 122 * (T213717) Fixed a translation error on Goan Konkani (gom-deva) translations
 123   for NS_TEMPLATE.
 124 * (T212221) Added $digitTransformTable for Santali (sat).
 125
 126 === Breaking changes in 1.33 ===
 127 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 128   Language. Other types are deprecated since 1.32.
 129 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 130   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 131   deprecated since 1.32.
 132 * Language::truncate(), deprecated in 1.31, has been removed.
 133 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 134   instead.
 135 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 136   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 137   use 'help', 'help-message', and 'help-messages'.
 138 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 139 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 140   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 141   Use the RESTBase v1 or Parsoid v3 API instead.
 142 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 143   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 144   has always been true at any rate.
 145 * Support for disabling tidy and external tidy implementations has been removed.
 146   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 147   used and no configuration is necessary.
 148 * A number of deprecated methods for API documentation, intended for overriding
 149   by extensions, are no longer called by MediaWiki, and will emit deprecation
 150   notices if your extension attempts to use them:
 151   * ApiBase::getDescription() (deprecated in 1.25)
 152   * ApiBase::getParamDescription() (deprecated in 1.25)
 153   * ApiBase::getExamples() (deprecated in 1.25)
 154   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 155   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 156   been removed, as their only use was to let extensions override values returned
 157   by getDescription() and getParamDescription(), respectively.
 158 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 159   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 160   the creation of AuthManager in 1.27, have been removed. This also means that
 161   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 162   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 163   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 164 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 165   use 'jquery.i18n'.
 166 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 167   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 168   respectively in a $wgExtensionMessagesFiles file.
 169 * The following methods of the Preferences class, deprecated in 1.31, have been
 170   removed:
 171   * getSaveBlacklist()
 172   * loadPreferenceValues()
 173   * getOptionFromUser()
 174   * profilePreferences()
 175   * skinPreferences()
 176   * filesPreferences()
 177   * datetimePreferences()
 178   * renderingPreferences()

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