  42 * (T198913) Added 'ApiOptions' hook.
  43 * …
  44
  45 === Action API internal changes in 1.33 ===
  46 * A number of deprecated methods for API documentation, intended for overriding
  47   by extensions, are no longer called by MediaWiki, and will emit deprecation
  48   notices if your extension attempts to use them:
  49   * ApiBase::getDescription() (deprecated in 1.25)
  50   * ApiBase::getParamDescription() (deprecated in 1.25)
  51   * ApiBase::getExamples() (deprecated in 1.25)
  52   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  53   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  54   been removed, as their only use was to let extensions override values returned
  55   by getDescription() and getParamDescription(), respectively.
  56 * …
  57
  58 === Languages updated in 1.33 ===
  59 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  60 Below only new and removed languages are listed, as well as changes to languages
  61 because of Phabricator reports.
  62
  63 * (T203908) Added language support for Eastern Pwo (kjp).
  64
  65 === Breaking changes in 1.33 ===
  66 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  67   Language. Other types are deprecated since 1.32.
  68 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  69   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  70   deprecated since 1.32.
  71 * Language::truncate(), deprecated in 1.31, has been removed.
  72 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  73   instead.
  74 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  75   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  76   use 'help', 'help-message', and 'help-messages'.
  77 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  78 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  79   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  80   Use the RESTBase v1 or Parsoid v3 API instead.
  81 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  82   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  83   has always been true at any rate.
  84 * A number of deprecated methods for API documentation, intended for overriding
  85   by extensions, are no longer called by MediaWiki, and will emit deprecation
  86   notices if your extension attempts to use them:
  87   * ApiBase::getDescription() (deprecated in 1.25)
  88   * ApiBase::getParamDescription() (deprecated in 1.25)
  89   * ApiBase::getExamples() (deprecated in 1.25)
  90   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  91   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  92   been removed, as their only use was to let extensions override values returned
  93   by getDescription() and getParamDescription(), respectively.
  94 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
  95   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
  96   the creation of AuthManager in 1.27, have been removed. This also means that
  97   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
  98   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
  99   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 100 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 101   use 'jquery.i18n'.
 102 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 103   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 104   respectively in a $wgExtensionMessagesFiles file.
 105 * …
 106
 107 === Deprecations in 1.33 ===
 108 * The configuration option $wgUseESI has been deprecated, and is expected
 109   to be removed in a future release.
 110 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 111   and is expected to be removed in a future release.
 112 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 113   introduced in MW 1.17, have been deprecated.  These fixes will always be
 114   applied for Arabic and Malayalam in the future.  Please enable these on
 115   your local wiki (if you have them explicitly set to false) and run
 116   maintenance/cleanupTitles.php to fix any existing page titles.
 117 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 118   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 119   This will help identify the issue if you added it to $wgAuthManagerConfig.
 120 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 121   domain ID as a key component and use makeGlobalKey().

 126
 127 == Compatibility ==
 128 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 129 supported, it is generally advised to use PHP 7.0.0 or later for long term
 130 support.
 131
 132 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 133 but support for them is somewhat less mature. There is experimental support for
 134 Oracle and Microsoft SQL Server.
 135
 136 The supported versions are:
 137
 138 * MySQL 5.5.8 or later
 139 * PostgreSQL 9.2 or later
 140 * SQLite 3.3.7 or later
 141 * Oracle 9.0.1 or later
 142 * Microsoft SQL Server 2005 (9.00.1399)
 143
 144 == Upgrading ==
 145 1.33 has several database changes since 1.32, and will not work without schema
 146 updates. Note that due to changes to some very large tables like the revision
 147 table, the schema update may take quite long (minutes on a medium sized site,
 148 many hours on a large site).
 149
 150 Don't forget to always back up your database before upgrading!
 151
 152 See the file UPGRADE for more detailed upgrade instructions, including
 153 important information when upgrading from versions prior to 1.11.
