   1 == MediaWiki 1.33 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.33 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.33 ===
   9
  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.
  23 * …
  24
  25 ==== Removed configuration ====
  26 * (T199334) $wgTagStatisticsNewTable — 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.
  29 * MediaWiki now always tidies user output, and most related
  30   configuration has been removed. Thus $wgUseTidy, $wgTidyBin,
  31   $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy, all
  32   deprecated since 1.26, have now all been removed. The $wgTidyConfig
  33   setting remains only for Remex experimental features or debugging.
  34 * …
  35
  36 === New features in 1.33 ===
  37 * The 'GetPreferences' hook now receives an additional $context parameter.

  53 === Bug fixes in 1.33 ===
  54 * …
  55
  56 === Action API changes in 1.33 ===
  57 * (T198913) Added 'ApiOptions' hook.
  58 * The JSON formatversion=2 is no longer experimental.
  59 * …
  60
  61 === Action API internal changes in 1.33 ===
  62 * A number of deprecated methods for API documentation, intended for overriding
  63   by extensions, are no longer called by MediaWiki, and will emit deprecation
  64   notices if your extension attempts to use them:
  65   * ApiBase::getDescription() (deprecated in 1.25)
  66   * ApiBase::getParamDescription() (deprecated in 1.25)
  67   * ApiBase::getExamples() (deprecated in 1.25)
  68   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  69   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  70   been removed, as their only use was to let extensions override values returned
  71   by getDescription() and getParamDescription(), respectively.
  72 * …
  73
  74 === Languages updated in 1.33 ===
  75 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  76 Below only new and removed languages are listed, as well as changes to languages
  77 because of Phabricator reports.
  78
  79 * (T203908) Added language support for Eastern Pwo (kjp).
  80
  81 === Breaking changes in 1.33 ===
  82 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  83   Language. Other types are deprecated since 1.32.
  84 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  85   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  86   deprecated since 1.32.
  87 * Language::truncate(), deprecated in 1.31, has been removed.
  88 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  89   instead.
  90 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  91   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  92   use 'help', 'help-message', and 'help-messages'.
  93 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  94 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  95   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  96   Use the RESTBase v1 or Parsoid v3 API instead.
  97 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  98   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  99   has always been true at any rate.
 100 * Support for disabling tidy and external tidy implementations has been removed.
 101   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 102   used and no configuration is necessary.
 103 * A number of deprecated methods for API documentation, intended for overriding
 104   by extensions, are no longer called by MediaWiki, and will emit deprecation
 105   notices if your extension attempts to use them:
 106   * ApiBase::getDescription() (deprecated in 1.25)
 107   * ApiBase::getParamDescription() (deprecated in 1.25)
 108   * ApiBase::getExamples() (deprecated in 1.25)
 109   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 110   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 111   been removed, as their only use was to let extensions override values returned
 112   by getDescription() and getParamDescription(), respectively.
 113 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 114   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 115   the creation of AuthManager in 1.27, have been removed. This also means that
 116   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 117   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 118   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 119 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 120   use 'jquery.i18n'.
 121 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 122   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 123   respectively in a $wgExtensionMessagesFiles file.
 124 * The following methods of the Preferences class, deprecated in 1.31, have been
 125   removed:
 126   * getSaveBlacklist()
 127   * loadPreferenceValues()
 128   * getOptionFromUser()
 129   * profilePreferences()
 130   * skinPreferences()
 131   * filesPreferences()
 132   * datetimePreferences()
 133   * renderingPreferences()
 134   * editingPreferences()
 135   * rcPreferences()
 136   * watchlistPreferences()
 137   * searchPreferences()
 138   * miscPreferences()
 139   * generateSkinOptions()
 140   * getDateOptions()
 141   * getImageSizes()
 142   * getThumbSizes()
 143   * validateSignature()
 144   * cleanSignature()
 145   * getTimezoneOptions()
 146   * filterIntval()
 147   * filterTimezoneInput()
 148   * getTimeZoneList()
 149
 150 === Deprecations in 1.33 ===
 151 * The configuration option $wgUseESI has been deprecated, and is expected
 152   to be removed in a future release.
 153 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 154   and is expected to be removed in a future release.
 155 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 156   introduced in MW 1.17, have been deprecated.  These fixes will always be
 157   applied for Arabic and Malayalam in the future.  Please enable these on
 158   your local wiki (if you have them explicitly set to false) and run
 159   maintenance/cleanupTitles.php to fix any existing page titles.
 160 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 161   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 162   This will help identify the issue if you added it to $wgAuthManagerConfig.
 163 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 164   domain ID as a key component and use makeGlobalKey().
 165 * …
 166
 167 === Other changes in 1.33 ===
 168 * (T208871) The hard-coded Google search form on the database error page was
 169   removed.
 170 * The image_comment_temp database table, deprecated in 1.32, has been removed.
 171   Since access should be mediated by the CommentStore class, this change
 172   shouldn't affect external code.
 173 * …
 174
 175 == Compatibility ==
 176 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 177 supported, it is generally advised to use PHP 7.0.0 or later for long term
 178 support.
 179
 180 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 181 but support for them is somewhat less mature. There is experimental support for
 182 Oracle and Microsoft SQL Server.
 183
 184 The supported versions are:
 185
 186 * MySQL 5.5.8 or later
 187 * PostgreSQL 9.2 or later
 188 * SQLite 3.3.7 or later
 189 * Oracle 9.0.1 or later
 190 * Microsoft SQL Server 2005 (9.00.1399)
 191
 192 == Upgrading ==
 193 1.33 has several database changes since 1.32, and will not work without schema
 194 updates. Note that due to changes to some very large tables like the revision
 195 table, the schema update may take quite long (minutes on a medium sized site,
 196 many hours on a large site).
 197
 198 Don't forget to always back up your database before upgrading!
 199
 200 See the file UPGRADE for more detailed upgrade instructions, including
 201 important information when upgrading from versions prior to 1.11.
