  44 * (T198913) Added 'ApiOptions' hook.
  45 * …
  46
  47 === Action API internal changes in 1.33 ===
  48 * A number of deprecated methods for API documentation, intended for overriding
  49   by extensions, are no longer called by MediaWiki, and will emit deprecation
  50   notices if your extension attempts to use them:
  51   * ApiBase::getDescription() (deprecated in 1.25)
  52   * ApiBase::getParamDescription() (deprecated in 1.25)
  53   * ApiBase::getExamples() (deprecated in 1.25)
  54   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  55   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  56   been removed, as their only use was to let extensions override values returned
  57   by getDescription() and getParamDescription(), respectively.
  58 * …
  59
  60 === Languages updated in 1.33 ===
  61 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  62 Below only new and removed languages are listed, as well as changes to languages
  63 because of Phabricator reports.
  64
  65 * (T203908) Added language support for Eastern Pwo (kjp).
  66
  67 === Breaking changes in 1.33 ===
  68 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  69   Language. Other types are deprecated since 1.32.
  70 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  71   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  72   deprecated since 1.32.
  73 * Language::truncate(), deprecated in 1.31, has been removed.
  74 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  75   instead.
  76 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  77   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  78   use 'help', 'help-message', and 'help-messages'.
  79 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  80 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  81   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  82   Use the RESTBase v1 or Parsoid v3 API instead.
  83 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  84   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  85   has always been true at any rate.
  86 * A number of deprecated methods for API documentation, intended for overriding
  87   by extensions, are no longer called by MediaWiki, and will emit deprecation
  88   notices if your extension attempts to use them:
  89   * ApiBase::getDescription() (deprecated in 1.25)
  90   * ApiBase::getParamDescription() (deprecated in 1.25)
  91   * ApiBase::getExamples() (deprecated in 1.25)
  92   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  93   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  94   been removed, as their only use was to let extensions override values returned
  95   by getDescription() and getParamDescription(), respectively.
  96 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
  97   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
  98   the creation of AuthManager in 1.27, have been removed. This also means that
  99   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 100   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 101   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 102 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 103   use 'jquery.i18n'.
 104 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 105   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 106   respectively in a $wgExtensionMessagesFiles file.
 107 * …
 108
 109 === Deprecations in 1.33 ===
 110 * The configuration option $wgUseESI has been deprecated, and is expected
 111   to be removed in a future release.
 112 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 113   and is expected to be removed in a future release.
 114 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 115   introduced in MW 1.17, have been deprecated.  These fixes will always be
 116   applied for Arabic and Malayalam in the future.  Please enable these on
 117   your local wiki (if you have them explicitly set to false) and run
 118   maintenance/cleanupTitles.php to fix any existing page titles.
 119 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 120   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 121   This will help identify the issue if you added it to $wgAuthManagerConfig.
 122 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 123   domain ID as a key component and use makeGlobalKey().
 124 * …

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