   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
  25 ==== Removed configuration ====
  26 * (T199334) $wgTagStatisticsNewTable — This temporary setting, added in
  27   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  28   will now always use the `change_tag_def` instead of the `change_tag` table.
  29 * MediaWiki now always tidies user output, and most related
  30   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  31   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  32   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  33   setting remains only for Remex experimental features or debugging.
  34 * …
  35
  36 === New features in 1.33 ===
  37 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  38   to be hidden on Special:UnusedCategories.
  39 * Add PasswordPolicy to check the password isn't in the large blacklist.
  40 * …
  41
  42 === External library changes in 1.33 ===

  61 === Bug fixes in 1.33 ===
  62 * …
  63
  64 === Action API changes in 1.33 ===
  65 * (T198913) Added 'ApiOptions' hook.
  66 * The JSON formatversion=2 is no longer experimental.
  67 * Internal API errors (those with code beginning "internal_api_error") will
  68   include the exception class name in a data field named "errorclass".
  69   * Class names are not guaranteed to remain stable, and in particular database
  70     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  71   * The code including an exception class name is deprecated. In the future,
  72     all internal errors will use code "internal_api_error".
  73 * …
  74
  75 === Action API internal changes in 1.33 ===
  76 * A number of deprecated methods for API documentation, intended for overriding
  77   by extensions, are no longer called by MediaWiki, and will emit deprecation
  78   notices if your extension attempts to use them:
  79   * ApiBase::getDescription() (deprecated in 1.25)
  80   * ApiBase::getParamDescription() (deprecated in 1.25)
  81   * ApiBase::getExamples() (deprecated in 1.25)
  82   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  83   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  84   been removed, as their only use was to let extensions override values returned
  85   by getDescription() and getParamDescription(), respectively.
  86 * API error codes may only contain ASCII letters, numbers, underscore, and
  87   hyphen. Methods such as ApiBase::dieWithError() and
  88   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  89   passed a bad code.
  90 * …
  91
  92 === Languages updated in 1.33 ===
  93 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  94 Below only new and removed languages are listed, as well as changes to languages
  95 because of Phabricator reports.
  96
  97 * (T203908) Added language support for Eastern Pwo (kjp).
  98
  99 === Breaking changes in 1.33 ===
 100 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 101   Language. Other types are deprecated since 1.32.
 102 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 103   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 104   deprecated since 1.32.
 105 * Language::truncate(), deprecated in 1.31, has been removed.
 106 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 107   instead.
 108 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 109   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 110   use 'help', 'help-message', and 'help-messages'.
 111 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 112 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 113   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 114   Use the RESTBase v1 or Parsoid v3 API instead.
 115 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 116   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 117   has always been true at any rate.
 118 * Support for disabling tidy and external tidy implementations has been removed.
 119   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 120   used and no configuration is necessary.
 121 * A number of deprecated methods for API documentation, intended for overriding
 122   by extensions, are no longer called by MediaWiki, and will emit deprecation
 123   notices if your extension attempts to use them:
 124   * ApiBase::getDescription() (deprecated in 1.25)
 125   * ApiBase::getParamDescription() (deprecated in 1.25)
 126   * ApiBase::getExamples() (deprecated in 1.25)
 127   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 128   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 129   been removed, as their only use was to let extensions override values returned
 130   by getDescription() and getParamDescription(), respectively.
 131 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 132   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 133   the creation of AuthManager in 1.27, have been removed. This also means that
 134   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 135   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 136   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 137 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 138   use 'jquery.i18n'.
 139 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 140   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 141   respectively in a $wgExtensionMessagesFiles file.
 142 * The following methods of the Preferences class, deprecated in 1.31, have been
 143   removed:
 144   * getSaveBlacklist()
 145   * loadPreferenceValues()
 146   * getOptionFromUser()
 147   * profilePreferences()
 148   * skinPreferences()
 149   * filesPreferences()
 150   * datetimePreferences()
 151   * renderingPreferences()
 152   * editingPreferences()
 153   * rcPreferences()
 154   * watchlistPreferences()
 155   * searchPreferences()
 156   * miscPreferences()
 157   * generateSkinOptions()
 158   * getDateOptions()
 159   * getImageSizes()
 160   * getThumbSizes()
 161   * validateSignature()
 162   * cleanSignature()
 163   * getTimezoneOptions()
 164   * filterIntval()
 165   * filterTimezoneInput()
 166   * getTimeZoneList()
 167 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 168 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 169
 170 === Deprecations in 1.33 ===
 171 * The configuration option $wgUseESI has been deprecated, and is expected
 172   to be removed in a future release.
 173 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 174   and is expected to be removed in a future release.
 175 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 176   introduced in MW 1.17, have been deprecated.  These fixes will always be
 177   applied for Arabic and Malayalam in the future.  Please enable these on
 178   your local wiki (if you have them explicitly set to false) and run
 179   maintenance/cleanupTitles.php to fix any existing page titles.
 180 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 181   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 182   This will help identify the issue if you added it to $wgAuthManagerConfig.
 183 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 184   domain ID as a key component and use makeGlobalKey().
 185 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 186   Title::getDBKey(), which doesn't vary case.
 187 * …
 188
 189 === Other changes in 1.33 ===
 190 * (T208871) The hard-coded Google search form on the database error page was
 191   removed.
 192 * …
 193
 194 == Compatibility ==
 195 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 196 supported, it is generally advised to use PHP 7.0.0 or later for long term
 197 support.
 198
 199 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 200 but support for them is somewhat less mature. There is experimental support for
 201 Oracle and Microsoft SQL Server.
 202
 203 The supported versions are:
 204
 205 * MySQL 5.5.8 or later
 206 * PostgreSQL 9.2 or later
 207 * SQLite 3.3.7 or later
 208 * Oracle 9.0.1 or later
 209 * Microsoft SQL Server 2005 (9.00.1399)
 210
 211 == Upgrading ==
 212 1.33 has several database changes since 1.32, and will not work without schema
 213 updates. Note that due to changes to some very large tables like the revision
 214 table, the schema update may take quite long (minutes on a medium sized site,
 215 many hours on a large site).
 216
 217 Don't forget to always back up your database before upgrading!
 218
 219 See the file UPGRADE for more detailed upgrade instructions, including
 220 important information when upgrading from versions prior to 1.11.
