   6 production.

   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 * …

  31 === New features in 1.33 ===
  32 * The 'GetPreferences' hook now receives an additional $context parameter.

  36 * …

  53 * …
  54
  55 === Action API changes in 1.33 ===
  56 * (T198913) Added 'ApiOptions' hook.
  57 * The JSON formatversion=2 is no longer experimental.
  58 * Internal API errors (those with code beginning "internal_api_error") will
  59   include the exception class name in a data field named "errorclass".
  60   * Class names are not guaranteed to remain stable, and in particular database
  61     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  62   * The code including an exception class name is deprecated. In the future,
  63     all internal errors will use code "internal_api_error".
  64 * …
  65
  66 === Action API internal changes in 1.33 ===
  67 * A number of deprecated methods for API documentation, intended for overriding
  68   by extensions, are no longer called by MediaWiki, and will emit deprecation
  69   notices if your extension attempts to use them:
  70   * ApiBase::getDescription() (deprecated in 1.25)
  71   * ApiBase::getParamDescription() (deprecated in 1.25)
  72   * ApiBase::getExamples() (deprecated in 1.25)
  73   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  74   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  75   been removed, as their only use was to let extensions override values returned
  76   by getDescription() and getParamDescription(), respectively.
  77 * API error codes may only contain ASCII letters, numbers, underscore, and
  78   hyphen. Methods such as ApiBase::dieWithError() and
  79   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  80   passed a bad code.
  81 * …
  82
  83 === Languages updated in 1.33 ===
  84 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  85 Below only new and removed languages are listed, as well as changes to languages
  86 because of Phabricator reports.
  87
  88 * (T203908) Added language support for Eastern Pwo (kjp).
  89
  90 === Breaking changes in 1.33 ===
  91 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  92   Language. Other types are deprecated since 1.32.
  93 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  94   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  95   deprecated since 1.32.
  96 * Language::truncate(), deprecated in 1.31, has been removed.
  97 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  98   instead.
  99 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 100   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 101   use 'help', 'help-message', and 'help-messages'.
 102 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 103 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 104   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 105   Use the RESTBase v1 or Parsoid v3 API instead.
 106 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 107   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 108   has always been true at any rate.
 109 * A number of deprecated methods for API documentation, intended for overriding
 110   by extensions, are no longer called by MediaWiki, and will emit deprecation
 111   notices if your extension attempts to use them:
 112   * ApiBase::getDescription() (deprecated in 1.25)
 113   * ApiBase::getParamDescription() (deprecated in 1.25)
 114   * ApiBase::getExamples() (deprecated in 1.25)
 115   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 116   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 117   been removed, as their only use was to let extensions override values returned
 118   by getDescription() and getParamDescription(), respectively.
 119 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 120   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 121   the creation of AuthManager in 1.27, have been removed. This also means that
 122   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 123   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 124   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 125 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 126   use 'jquery.i18n'.
 127 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 128   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 129   respectively in a $wgExtensionMessagesFiles file.
 130 * The following methods of the Preferences class, deprecated in 1.31, have been
 131   removed:
 132   * getSaveBlacklist()
 133   * loadPreferenceValues()
 134   * getOptionFromUser()
 135   * profilePreferences()

 152   * filterIntval()
 153   * filterTimezoneInput()
 154   * getTimeZoneList()
 155 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 156 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 157
 158 === Deprecations in 1.33 ===
 159 * The configuration option $wgUseESI has been deprecated, and is expected
 160   to be removed in a future release.
 161 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 162   and is expected to be removed in a future release.
 163 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 164   introduced in MW 1.17, have been deprecated.  These fixes will always be
 165   applied for Arabic and Malayalam in the future.  Please enable these on
 166   your local wiki (if you have them explicitly set to false) and run
 167   maintenance/cleanupTitles.php to fix any existing page titles.
 168 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 169   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 170   This will help identify the issue if you added it to $wgAuthManagerConfig.
 171 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 172   domain ID as a key component and use makeGlobalKey().
 173 * …
 174
 175 === Other changes in 1.33 ===
 176 * (T208871) The hard-coded Google search form on the database error page was
 177   removed.
 178 * …
 179
 180 == Compatibility ==
 181 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 182 supported, it is generally advised to use PHP 7.0.0 or later for long term
 183 support.
 184
 185 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 186 but support for them is somewhat less mature. There is experimental support for
 187 Oracle and Microsoft SQL Server.
 188
 189 The supported versions are:
 190
 191 * MySQL 5.5.8 or later
 192 * PostgreSQL 9.2 or later
 193 * SQLite 3.3.7 or later
 194 * Oracle 9.0.1 or later
 195 * Microsoft SQL Server 2005 (9.00.1399)
 196
 197 == Upgrading ==
 198 1.33 has several database changes since 1.32, and will not work without schema
 199 updates. Note that due to changes to some very large tables like the revision
 200 table, the schema update may take quite long (minutes on a medium sized site,
 201 many hours on a large site).
 202
 203 Don't forget to always back up your database before upgrading!
 204
 205 See the file UPGRADE for more detailed upgrade instructions, including
 206 important information when upgrading from versions prior to 1.11.
