   8 === Configuration changes in 1.33 ===

  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
  22   MediaWiki 1.32, now defaults to MIGRATION_NEW instead of MIGRATION_WRITE_BOTH.

  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.

  31 === New features in 1.33 ===

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