  47 * (T198913) Added 'ApiOptions' hook.
  48 * …
  49
  50 === Action API internal changes in 1.33 ===
  51 * A number of deprecated methods for API documentation, intended for overriding
  52   by extensions, are no longer called by MediaWiki, and will emit deprecation
  53   notices if your extension attempts to use them:
  54   * ApiBase::getDescription() (deprecated in 1.25)
  55   * ApiBase::getParamDescription() (deprecated in 1.25)
  56   * ApiBase::getExamples() (deprecated in 1.25)
  57   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  58   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  59   been removed, as their only use was to let extensions override values returned
  60   by getDescription() and getParamDescription(), respectively.
  61 * …
  62
  63 === Languages updated in 1.33 ===
  64 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  65 Below only new and removed languages are listed, as well as changes to languages
  66 because of Phabricator reports.
  67
  68 * (T203908) Added language support for Eastern Pwo (kjp).
  69
  70 === Breaking changes in 1.33 ===
  71 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  72   Language. Other types are deprecated since 1.32.
  73 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  74   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  75   deprecated since 1.32.
  76 * Language::truncate(), deprecated in 1.31, has been removed.
  77 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  78   instead.
  79 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  80   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  81   use 'help', 'help-message', and 'help-messages'.
  82 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  83 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  84   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  85   Use the RESTBase v1 or Parsoid v3 API instead.
  86 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  87   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  88   has always been true at any rate.
  89 * A number of deprecated methods for API documentation, intended for overriding
  90   by extensions, are no longer called by MediaWiki, and will emit deprecation
  91   notices if your extension attempts to use them:
  92   * ApiBase::getDescription() (deprecated in 1.25)
  93   * ApiBase::getParamDescription() (deprecated in 1.25)
  94   * ApiBase::getExamples() (deprecated in 1.25)
  95   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  96   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  97   been removed, as their only use was to let extensions override values returned
  98   by getDescription() and getParamDescription(), respectively.
  99 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 100   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 101   the creation of AuthManager in 1.27, have been removed. This also means that
 102   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 103   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 104   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 105 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 106   use 'jquery.i18n'.
 107 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 108   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 109   respectively in a $wgExtensionMessagesFiles file.
 110 * The following methods of the Preferences class, deprecated in 1.31, have been
 111   removed:
 112   * getSaveBlacklist()
 113   * loadPreferenceValues()
 114   * getOptionFromUser()
 115   * profilePreferences()
 116   * skinPreferences()
 117   * filesPreferences()
 118   * datetimePreferences()

 128   * getThumbSizes()
 129   * validateSignature()
 130   * cleanSignature()

 132   * filterIntval()
 133   * filterTimezoneInput()
 134   * getTimeZoneList()
 135
 136 === Deprecations in 1.33 ===
 137 * The configuration option $wgUseESI has been deprecated, and is expected
 138   to be removed in a future release.
 139 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 140   and is expected to be removed in a future release.
 141 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 142   introduced in MW 1.17, have been deprecated.  These fixes will always be
 143   applied for Arabic and Malayalam in the future.  Please enable these on
 144   your local wiki (if you have them explicitly set to false) and run
 145   maintenance/cleanupTitles.php to fix any existing page titles.
 146 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 147   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 148   This will help identify the issue if you added it to $wgAuthManagerConfig.
 149 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 150   domain ID as a key component and use makeGlobalKey().
 151 * …
 152
 153 === Other changes in 1.33 ===
 154 * (T208871) The hard-coded Google search form on the database error page was
 155   removed.
 156 * …
 157
 158 == Compatibility ==
 159 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 160 supported, it is generally advised to use PHP 7.0.0 or later for long term
 161 support.
 162
 163 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 164 but support for them is somewhat less mature. There is experimental support for
 165 Oracle and Microsoft SQL Server.
 166
 167 The supported versions are:
 168
 169 * MySQL 5.5.8 or later
 170 * PostgreSQL 9.2 or later
 171 * SQLite 3.3.7 or later
 172 * Oracle 9.0.1 or later
 173 * Microsoft SQL Server 2005 (9.00.1399)
 174
 175 == Upgrading ==
 176 1.33 has several database changes since 1.32, and will not work without schema
 177 updates. Note that due to changes to some very large tables like the revision
 178 table, the schema update may take quite long (minutes on a medium sized site,
 179 many hours on a large site).
 180
 181 Don't forget to always back up your database before upgrading!
 182
 183 See the file UPGRADE for more detailed upgrade instructions, including
 184 important information when upgrading from versions prior to 1.11.
