  10 ==== New configuration ====
  11 * $wgEnablePartialBlocks – This enables the Partial Blocks feature, which gives
  12   accounts with block permissions the ability to block users, IPs, and IP ranges
  13   from editing specific pages, while allowing them to edit the rest of the wiki.
  14 * $wgMediaInTargetLanguage – whether multilingual images should be dispalyed in
  15   the current parse language where available.
  16
  17 ==== Changed configuration ====
  18 * Some external link searches will not work correctly until update.php (or
  19   refreshExternallinksIndex.php) is run. These include searches for links using
  20   IP addresses, internationalized domain names, and possibly mailto links.
  21 * (T193868) $wgChangeTagsSchemaMigrationStage — This temporary setting, added in

  27   MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
  28   will now always use the `change_tag_def` instead of the `change_tag` table.

  51 * …
  52
  53 === Action API changes in 1.33 ===
  54 * (T198913) Added 'ApiOptions' hook.
  55 * The JSON formatversion=2 is no longer experimental.
  56 * …
  57
  58 === Action API internal changes in 1.33 ===
  59 * A number of deprecated methods for API documentation, intended for overriding
  60   by extensions, are no longer called by MediaWiki, and will emit deprecation
  61   notices if your extension attempts to use them:
  62   * ApiBase::getDescription() (deprecated in 1.25)
  63   * ApiBase::getParamDescription() (deprecated in 1.25)
  64   * ApiBase::getExamples() (deprecated in 1.25)
  65   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  66   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  67   been removed, as their only use was to let extensions override values returned
  68   by getDescription() and getParamDescription(), respectively.
  69 * …
  70
  71 === Languages updated in 1.33 ===
  72 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  73 Below only new and removed languages are listed, as well as changes to languages
  74 because of Phabricator reports.
  75
  76 * (T203908) Added language support for Eastern Pwo (kjp).
  77
  78 === Breaking changes in 1.33 ===
  79 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  80   Language. Other types are deprecated since 1.32.
  81 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  82   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  83   deprecated since 1.32.
  84 * Language::truncate(), deprecated in 1.31, has been removed.
  85 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  86   instead.
  87 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  88   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  89   use 'help', 'help-message', and 'help-messages'.
  90 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  91 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  92   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  93   Use the RESTBase v1 or Parsoid v3 API instead.
  94 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  95   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  96   has always been true at any rate.
  97 * A number of deprecated methods for API documentation, intended for overriding
  98   by extensions, are no longer called by MediaWiki, and will emit deprecation
  99   notices if your extension attempts to use them:
 100   * ApiBase::getDescription() (deprecated in 1.25)
 101   * ApiBase::getParamDescription() (deprecated in 1.25)
 102   * ApiBase::getExamples() (deprecated in 1.25)
 103   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 104   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 105   been removed, as their only use was to let extensions override values returned
 106   by getDescription() and getParamDescription(), respectively.
 107 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 108   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 109   the creation of AuthManager in 1.27, have been removed. This also means that
 110   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 111   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 112   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 113 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 114   use 'jquery.i18n'.
 115 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 116   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 117   respectively in a $wgExtensionMessagesFiles file.
 118 * The following methods of the Preferences class, deprecated in 1.31, have been
 119   removed:
 120   * getSaveBlacklist()
 121   * loadPreferenceValues()
 122   * getOptionFromUser()
 123   * profilePreferences()
 124   * skinPreferences()
 125   * filesPreferences()
 126   * datetimePreferences()
 127   * renderingPreferences()
 128   * editingPreferences()
 129   * rcPreferences()
 130   * watchlistPreferences()
 131   * searchPreferences()
 132   * miscPreferences()
 133   * generateSkinOptions()
 134   * getDateOptions()
 135   * getImageSizes()
 136   * getThumbSizes()
 137   * validateSignature()
 138   * cleanSignature()
 139   * getTimezoneOptions()
 140   * filterIntval()
 141   * filterTimezoneInput()
 142   * getTimeZoneList()
 143
 144 === Deprecations in 1.33 ===
 145 * The configuration option $wgUseESI has been deprecated, and is expected
 146   to be removed in a future release.
 147 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 148   and is expected to be removed in a future release.
 149 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 150   introduced in MW 1.17, have been deprecated.  These fixes will always be
 151   applied for Arabic and Malayalam in the future.  Please enable these on
 152   your local wiki (if you have them explicitly set to false) and run
 153   maintenance/cleanupTitles.php to fix any existing page titles.
 154 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 155   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 156   This will help identify the issue if you added it to $wgAuthManagerConfig.
 157 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 158   domain ID as a key component and use makeGlobalKey().
 159 * …
 160
 161 === Other changes in 1.33 ===
 162 * (T208871) The hard-coded Google search form on the database error page was
 163   removed.
 164 * The image_comment_temp database table, deprecated in 1.32, has been removed.
 165   Since access should be mediated by the CommentStore class, this change
 166   shouldn't affect external code.
 167 * …
 168
 169 == Compatibility ==
 170 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 171 supported, it is generally advised to use PHP 7.0.0 or later for long term
 172 support.
 173
 174 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 175 but support for them is somewhat less mature. There is experimental support for
 176 Oracle and Microsoft SQL Server.
 177
 178 The supported versions are:
 179
 180 * MySQL 5.5.8 or later
 181 * PostgreSQL 9.2 or later
 182 * SQLite 3.3.7 or later
 183 * Oracle 9.0.1 or later
 184 * Microsoft SQL Server 2005 (9.00.1399)
 185
 186 == Upgrading ==
 187 1.33 has several database changes since 1.32, and will not work without schema
 188 updates. Note that due to changes to some very large tables like the revision
 189 table, the schema update may take quite long (minutes on a medium sized site,
 190 many hours on a large site).
 191
 192 Don't forget to always back up your database before upgrading!
 193
 194 See the file UPGRADE for more detailed upgrade instructions, including
 195 important information when upgrading from versions prior to 1.11.
 196
 197 For notes on 1.32.x and older releases, see HISTORY.
