  43 * (T198913) Added 'ApiOptions' hook.
  44 * …
  45
  46 === Action API internal changes in 1.33 ===
  47 * A number of deprecated methods for API documentation, intended for overriding
  48   by extensions, are no longer called by MediaWiki, and will emit deprecation
  49   notices if your extension attempts to use them:
  50   * ApiBase::getDescription() (deprecated in 1.25)
  51   * ApiBase::getParamDescription() (deprecated in 1.25)
  52   * ApiBase::getExamples() (deprecated in 1.25)
  53   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  54   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  55   been removed, as their only use was to let extensions override values returned
  56   by getDescription() and getParamDescription(), respectively.
  57 * …
  58
  59 === Languages updated in 1.33 ===
  60 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  61 Below only new and removed languages are listed, as well as changes to languages
  62 because of Phabricator reports.
  63
  64 * (T203908) Added language support for Eastern Pwo (kjp).
  65
  66 === Breaking changes in 1.33 ===
  67 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  68   Language. Other types are deprecated since 1.32.
  69 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  70   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  71   deprecated since 1.32.
  72 * Language::truncate(), deprecated in 1.31, has been removed.
  73 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  74   instead.
  75 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  76   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  77   use 'help', 'help-message', and 'help-messages'.
  78 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  79 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  80   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  81   Use the RESTBase v1 or Parsoid v3 API instead.
  82 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  83   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  84   has always been true at any rate.
  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 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
  96   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
  97   the creation of AuthManager in 1.27, have been removed. This also means that
  98   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
  99   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 100   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 101 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 102   use 'jquery.i18n'.
 103 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 104   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 105   respectively in a $wgExtensionMessagesFiles file.
 106 * …
 107
 108 === Deprecations in 1.33 ===
 109 * The configuration option $wgUseESI has been deprecated, and is expected
 110   to be removed in a future release.
 111 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 112   and is expected to be removed in a future release.
 113 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 114   introduced in MW 1.17, have been deprecated.  These fixes will always be
 115   applied for Arabic and Malayalam in the future.  Please enable these on
 116   your local wiki (if you have them explicitly set to false) and run
 117   maintenance/cleanupTitles.php to fix any existing page titles.
 118 * OutputPage::parse() and OutputPage::parseInline() have been deprecated
 119   due to untidy output and inconsistent handling of wrapper divs and
 120   interface/content language defaults.  Use OutputPage::parseAsContent(),
 121   OutputPage::parseAsInterface(), or OutputPage::parseInlineAsInterface()
 122   as appropriate.
 123 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 124   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 125   This will help identify the issue if you added it to $wgAuthManagerConfig.
 126 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 127   domain ID as a key component and use makeGlobalKey().
 128 * …

 130 === Other changes in 1.33 ===
 131 * …
 132
 133 == Compatibility ==
 134 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 135 supported, it is generally advised to use PHP 7.0.0 or later for long term
 136 support.
 137
 138 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 139 but support for them is somewhat less mature. There is experimental support for
 140 Oracle and Microsoft SQL Server.
 141
 142 The supported versions are:
 143
 144 * MySQL 5.5.8 or later
 145 * PostgreSQL 9.2 or later
 146 * SQLite 3.3.7 or later
 147 * Oracle 9.0.1 or later
 148 * Microsoft SQL Server 2005 (9.00.1399)
 149
 150 == Upgrading ==
 151 1.33 has several database changes since 1.32, and will not work without schema
 152 updates. Note that due to changes to some very large tables like the revision
 153 table, the schema update may take quite long (minutes on a medium sized site,
 154 many hours on a large site).
 155
 156 Don't forget to always back up your database before upgrading!
 157
 158 See the file UPGRADE for more detailed upgrade instructions, including
 159 important information when upgrading from versions prior to 1.11.
