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
  24 ==== Removed configuration ====
  25 * (T199334) $wgTagStatisticsNewTable — This temporary setting, added in
  26   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  27   will now always use the `change_tag_def` instead of the `change_tag` table.
  28 * MediaWiki now always tidies user output, and most related
  29   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  30   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  31   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  32   setting remains only for Remex experimental features or debugging.
  33 * $wgEnableParserCache, deprecated since 1.26, was removed.
  34   If disabling the parser cache is still desirable,
  35   set `$wgParserCacheType = CACHE_NONE;` instead.
  36
  37 === New features in 1.33 ===
  38 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  39   to be hidden on Special:UnusedCategories.
  40 * Add PasswordPolicy to check the password isn't in the large blacklist.
  41 * The AuthManagerLoginAuthenticateAudit hook has a new parameter for
  42   additional information about the authentication event.
  43 * TextContent::getText() was introduced as a replacement for
  44   Content::getNativeData() for text-based content models.
  45 * (T210814) SVGs are now by default displayed in wiki language on image
  46   pages.
  47
  48 === External library changes in 1.33 ===
  49
  50 ==== New external libraries ====
  51 * Added wikimedia/password-blacklist 0.1.4.
  52 * Added guzzlehttp/guzzle 6.3.3.
  53
  54 ==== Changed external libraries ====
  55 * Updated OOUI from v0.29.2 to v0.30.2.
  56 * Updated wikimedia/xmp-reader from 0.6.0 to 0.6.1.
  57 * Updated wikimedia/scoped-callback from 2.0.0 to 3.0.0.
  58 * Updated wikimedia/ip-set from 1.2.0 to 2.0.0.
  59   * The deprecated IPSet\IPSet alias was removed, Wikimedia\IPSet must be
  60     used instead.
  61 * Updated qunitjs from 2.6.2 to 2.9.1.
  62
  63 ==== Removed external libraries ====
  64
  65 === Bug fixes in 1.33 ===
  66 * (T164211) Special:UserRights could sometimes fail with a
  67   "conflict detected" error when there weren't any conflicts.
  68
  69 === Action API changes in 1.33 ===
  70 * (T198913) Added 'ApiOptions' hook.
  71 * The JSON formatversion=2 is no longer experimental.
  72 * Internal API errors (those with code beginning "internal_api_error") will
  73   include the exception class name in a data field named "errorclass".
  74   * Class names are not guaranteed to remain stable, and in particular database
  75     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  76   * The code including an exception class name is deprecated. In the future,
  77     all internal errors will use code "internal_api_error".
  78 * (T212356) When using action=delete on pages with many revisions, the module
  79   may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
  80   deletion will be processed via the job queue.
  81 * action=setnotificationtimestamp will now update the watchlist asynchronously
  82   if entirewatchlist is set, so updates may not be visible immediately
  83
  84 === Action API internal changes in 1.33 ===
  85 * A number of deprecated methods for API documentation, intended for overriding
  86   by extensions, are no longer called by MediaWiki, and will emit deprecation
  87   notices if your extension attempts to use them:
  88   * ApiBase::getDescription() (deprecated in 1.25)
  89   * ApiBase::getParamDescription() (deprecated in 1.25)
  90   * ApiBase::getExamples() (deprecated in 1.25)
  91   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  92   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  93   been removed, as their only use was to let extensions override values returned
  94   by getDescription() and getParamDescription(), respectively.
  95 * API error codes may only contain ASCII letters, numbers, underscore, and
  96   hyphen. Methods such as ApiBase::dieWithError() and
  97   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  98   passed a bad code.
  99
 100 === Languages updated in 1.33 ===
 101 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 102 Below only new and removed languages are listed, as well as changes to languages
 103 because of Phabricator reports.
 104
 105 * (T203908) Added language support for Eastern Pwo (kjp).
 106 * (T213717) Fixed a translation error on Goan Konkani (gom-deva) translations
 107   for NS_TEMPLATE.
 108 * (T212221) Added $digitTransformTable for Santali (sat).
 109
 110 === Breaking changes in 1.33 ===
 111 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 112   Language. Other types are deprecated since 1.32.
 113 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 114   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 115   deprecated since 1.32.
 116 * Language::truncate(), deprecated in 1.31, has been removed.
 117 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 118   instead.
 119 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 120   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 121   use 'help', 'help-message', and 'help-messages'.
 122 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 123 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 124   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 125   Use the RESTBase v1 or Parsoid v3 API instead.
 126 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 127   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 128   has always been true at any rate.
 129 * Support for disabling tidy and external tidy implementations has been removed.
 130   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 131   used and no configuration is necessary.
 132 * A number of deprecated methods for API documentation, intended for overriding
 133   by extensions, are no longer called by MediaWiki, and will emit deprecation
 134   notices if your extension attempts to use them:
 135   * ApiBase::getDescription() (deprecated in 1.25)
 136   * ApiBase::getParamDescription() (deprecated in 1.25)
 137   * ApiBase::getExamples() (deprecated in 1.25)
 138   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 139   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 140   been removed, as their only use was to let extensions override values returned
 141   by getDescription() and getParamDescription(), respectively.
 142 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 143   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 144   the creation of AuthManager in 1.27, have been removed. This also means that
 145   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 146   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 147   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 148 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 149   use 'jquery.i18n'.
 150 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 151   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 152   respectively in a $wgExtensionMessagesFiles file.
 153 * The following methods of the Preferences class, deprecated in 1.31, have been
 154   removed:
 155   * getSaveBlacklist()
 156   * loadPreferenceValues()
 157   * getOptionFromUser()
 158   * profilePreferences()
 159   * skinPreferences()
 160   * filesPreferences()
 161   * datetimePreferences()

 164   * rcPreferences()
 165   * watchlistPreferences()
 166   * searchPreferences()
 167   * miscPreferences()
 168   * generateSkinOptions()
 169   * getDateOptions()
 170   * getImageSizes()
 171   * getThumbSizes()
 172   * validateSignature()
 173   * cleanSignature()
 174   * getTimezoneOptions()
 175   * filterIntval()
 176   * filterTimezoneInput()
 177   * getTimeZoneList()
 178 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 179 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 180 * The 'mediawiki.api' module aliases, deprecated in 1.32, have been removed.
 181   Specifically: mediawiki.api.category, mediawiki.api.edit,
 182   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 183   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 184   mediawiki.api.messages, and mediawiki.api.rollback.
 185 * The 'jquery.byteLimit' module alias for 'jquery.lengthLimit',
 186   deprecated in 1.31, was removed.
 187 * Revision::fetchRevision(), deprecated in 1.28, was removed.
 188 * Class SquidUpdate, deprecated in 1.27, was removed.
 189
 190 === Deprecations in 1.33 ===
 191 * The configuration option $wgUseESI has been deprecated, and is expected
 192   to be removed in a future release.
 193 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 194   and is expected to be removed in a future release.
 195 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 196   introduced in MW 1.17, have been deprecated.  These fixes will always be
 197   applied for Arabic and Malayalam in the future.  Please enable these on
 198   your local wiki (if you have them explicitly set to false) and run
 199   maintenance/cleanupTitles.php to fix any existing page titles.
 200 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 201   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 202   This will help identify the issue if you added it to $wgAuthManagerConfig.
 203 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 204   domain ID as a key component and use makeGlobalKey().
 205 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 206   Title::getDBKey(), which doesn't vary case.
 207 * User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
 208   returns the same information in a more useful format.
 209 * For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
 210   as the $lang parameter was deprecated. The same applies to DummyLinker.
 211 * The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
 212   follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
 213   instead which blacklists 100,000 commonly used passwords.
 214 * (T208862) Action::requiresUnblock() is now called from
 215   Title::getUserPermissionsErrors() and Title::userCan(). Previously, the method
 216   was only called in Action::checkCanExecute(). Actions should ensure that their
 217   requiresUnblock() returns the proper result (the default is `true`).
 218 * (T211608) The MediaWiki\Services namespace has been renamed to
 219   Wikimedia\Services. The old name is still supported, but deprecated.
 220 * (T155582) Content::getNativeData has been deprecated. Please use model-
 221   specific getters, such as TextContent::getText().
 222 * The class WebInstallerOutput is now marked as @private.
 223 * (T209699) The jquery.async module has been deprecated. JavaScript code that
 224   needs asynchronous behaviour should use Promises.
 225 * Password::equals() is deprecated, use verify().
 226 * BaseTemplate::msgWiki() and QuickTemplate::msgWiki() will be removed. Use
 227   other means to fetch a properly escaped message string or Message object.
 228 * (T126091) The 'ResourceLoaderTestModules' hook, which lets you declare QUnit
 229   testing code for your JavaScript modules, is deprecated. Instead, you can now
 230   use the new extension registration key 'QUnitTestModule'.
 231
 232 === Other changes in 1.33 ===
 233 * (T208871) The hard-coded Google search form on the database error page was
 234   removed.
 235 * (T201747) Html::openElement() warns if given an element name with a space
 236   in it.
 237
 238 == Compatibility ==
 239 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 240 supported, it is generally advised to use PHP 7.0.0 or later for long term
 241 support.
 242
 243 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 244 but support for them is somewhat less mature. There is experimental support for
 245 Oracle and Microsoft SQL Server.
 246
 247 The supported versions are:
 248
 249 * MySQL 5.5.8 or later
 250 * PostgreSQL 9.2 or later
 251 * SQLite 3.3.7 or later
 252 * Oracle 9.0.1 or later
 253 * Microsoft SQL Server 2005 (9.00.1399)
 254
 255 == Upgrading ==
 256 1.33 has several database changes since 1.32, and will not work without schema
 257 updates. Note that due to changes to some very large tables like the revision
 258 table, the schema update may take quite long (minutes on a medium sized site,
 259 many hours on a large site).
 260
 261 Don't forget to always back up your database before upgrading!
 262
 263 See the file UPGRADE for more detailed upgrade instructions, including
 264 important information when upgrading from versions prior to 1.11.
 265
 266 For notes on 1.32.x and older releases, see HISTORY.
 267
