  47 * (T198913) Added 'ApiOptions' hook.
  48 * The JSON formatversion=2 is no longer experimental.
  49 * …
  50
  51 === Action API internal changes in 1.33 ===
  52 * A number of deprecated methods for API documentation, intended for overriding
  53   by extensions, are no longer called by MediaWiki, and will emit deprecation
  54   notices if your extension attempts to use them:
  55   * ApiBase::getDescription() (deprecated in 1.25)
  56   * ApiBase::getParamDescription() (deprecated in 1.25)
  57   * ApiBase::getExamples() (deprecated in 1.25)
  58   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  59   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  60   been removed, as their only use was to let extensions override values returned
  61   by getDescription() and getParamDescription(), respectively.
  62 * …
  63
  64 === Languages updated in 1.33 ===
  65 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  66 Below only new and removed languages are listed, as well as changes to languages
  67 because of Phabricator reports.
  68
  69 * (T203908) Added language support for Eastern Pwo (kjp).
  70
  71 === Breaking changes in 1.33 ===
  72 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  73   Language. Other types are deprecated since 1.32.
  74 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  75   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  76   deprecated since 1.32.
  77 * Language::truncate(), deprecated in 1.31, has been removed.
  78 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  79   instead.
  80 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  81   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  82   use 'help', 'help-message', and 'help-messages'.
  83 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  84 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  85   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  86   Use the RESTBase v1 or Parsoid v3 API instead.
  87 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  88   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  89   has always been true at any rate.
  90 * A number of deprecated methods for API documentation, intended for overriding
  91   by extensions, are no longer called by MediaWiki, and will emit deprecation
  92   notices if your extension attempts to use them:
  93   * ApiBase::getDescription() (deprecated in 1.25)
  94   * ApiBase::getParamDescription() (deprecated in 1.25)
  95   * ApiBase::getExamples() (deprecated in 1.25)
  96   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  97   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  98   been removed, as their only use was to let extensions override values returned
  99   by getDescription() and getParamDescription(), respectively.
 100 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 101   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 102   the creation of AuthManager in 1.27, have been removed. This also means that
 103   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 104   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 105   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 106 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 107   use 'jquery.i18n'.
 108 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 109   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 110   respectively in a $wgExtensionMessagesFiles file.
 111 * The following methods of the Preferences class, deprecated in 1.31, have been
 112   removed:
 113   * getSaveBlacklist()
 114   * loadPreferenceValues()
 115   * getOptionFromUser()
 116   * profilePreferences()
 117   * skinPreferences()
 118   * filesPreferences()
 119   * datetimePreferences()
 120   * renderingPreferences()
 121   * editingPreferences()
 122   * rcPreferences()
 123   * watchlistPreferences()
 124   * searchPreferences()

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