   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.
  38 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  39   to be hidden on Special:UnusedCategories.
  40 * Add PasswordPolicy to check the password isn't in the large blacklist.
  41 * …
  42
  43 === External library changes in 1.33 ===
  44
  45 ==== New external libraries ====
  46 * Added wikimedia/password-blacklist 0.1.4.
  47 * …
  48
  49 ==== Changed external libraries ====
  50 * Updated wikimedia/xmp-reader from 0.6.0 to 0.6.1.
  51 * Updated wikimedia/scoped-callback from 2.0.0 to 3.0.0.
  52 * …

  57 === Bug fixes in 1.33 ===
  58 * …
  59
  60 === Action API changes in 1.33 ===
  61 * (T198913) Added 'ApiOptions' hook.
  62 * The JSON formatversion=2 is no longer experimental.
  63 * Internal API errors (those with code beginning "internal_api_error") will
  64   include the exception class name in a data field named "errorclass".
  65   * Class names are not guaranteed to remain stable, and in particular database
  66     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  67   * The code including an exception class name is deprecated. In the future,
  68     all internal errors will use code "internal_api_error".
  69 * …
  70
  71 === Action API internal changes in 1.33 ===
  72 * A number of deprecated methods for API documentation, intended for overriding
  73   by extensions, are no longer called by MediaWiki, and will emit deprecation
  74   notices if your extension attempts to use them:
  75   * ApiBase::getDescription() (deprecated in 1.25)
  76   * ApiBase::getParamDescription() (deprecated in 1.25)
  77   * ApiBase::getExamples() (deprecated in 1.25)
  78   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  79   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  80   been removed, as their only use was to let extensions override values returned
  81   by getDescription() and getParamDescription(), respectively.
  82 * API error codes may only contain ASCII letters, numbers, underscore, and
  83   hyphen. Methods such as ApiBase::dieWithError() and
  84   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  85   passed a bad code.
  86 * …
  87
  88 === Languages updated in 1.33 ===
  89 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  90 Below only new and removed languages are listed, as well as changes to languages
  91 because of Phabricator reports.
  92
  93 * (T203908) Added language support for Eastern Pwo (kjp).
  94
  95 === Breaking changes in 1.33 ===
  96 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  97   Language. Other types are deprecated since 1.32.
  98 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  99   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 100   deprecated since 1.32.
 101 * Language::truncate(), deprecated in 1.31, has been removed.
 102 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 103   instead.
 104 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 105   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 106   use 'help', 'help-message', and 'help-messages'.
 107 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 108 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 109   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 110   Use the RESTBase v1 or Parsoid v3 API instead.
 111 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 112   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 113   has always been true at any rate.
 114 * Support for disabling tidy and external tidy implementations has been removed.
 115   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 116   used and no configuration is necessary.
 117 * A number of deprecated methods for API documentation, intended for overriding
 118   by extensions, are no longer called by MediaWiki, and will emit deprecation
 119   notices if your extension attempts to use them:
 120   * ApiBase::getDescription() (deprecated in 1.25)
 121   * ApiBase::getParamDescription() (deprecated in 1.25)
 122   * ApiBase::getExamples() (deprecated in 1.25)
 123   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 124   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 125   been removed, as their only use was to let extensions override values returned
 126   by getDescription() and getParamDescription(), respectively.
 127 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 128   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 129   the creation of AuthManager in 1.27, have been removed. This also means that
 130   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 131   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 132   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 133 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 134   use 'jquery.i18n'.
 135 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 136   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 137   respectively in a $wgExtensionMessagesFiles file.
 138 * The following methods of the Preferences class, deprecated in 1.31, have been
 139   removed:
 140   * getSaveBlacklist()
 141   * loadPreferenceValues()
 142   * getOptionFromUser()
 143   * profilePreferences()
 144   * skinPreferences()
 145   * filesPreferences()
 146   * datetimePreferences()
 147   * renderingPreferences()
 148   * editingPreferences()
 149   * rcPreferences()
 150   * watchlistPreferences()
 151   * searchPreferences()
 152   * miscPreferences()
 153   * generateSkinOptions()
 154   * getDateOptions()
 155   * getImageSizes()
 156   * getThumbSizes()
 157   * validateSignature()
 158   * cleanSignature()
 159   * getTimezoneOptions()
 160   * filterIntval()
 161   * filterTimezoneInput()
 162   * getTimeZoneList()
 163 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 164 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 165
 166 === Deprecations in 1.33 ===
 167 * The configuration option $wgUseESI has been deprecated, and is expected
 168   to be removed in a future release.
 169 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 170   and is expected to be removed in a future release.
 171 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 172   introduced in MW 1.17, have been deprecated.  These fixes will always be
 173   applied for Arabic and Malayalam in the future.  Please enable these on
 174   your local wiki (if you have them explicitly set to false) and run
 175   maintenance/cleanupTitles.php to fix any existing page titles.
 176 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 177   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 178   This will help identify the issue if you added it to $wgAuthManagerConfig.
 179 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 180   domain ID as a key component and use makeGlobalKey().
 181 * …
 182
 183 === Other changes in 1.33 ===
 184 * (T208871) The hard-coded Google search form on the database error page was
 185   removed.
 186 * …
 187
 188 == Compatibility ==
 189 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 190 supported, it is generally advised to use PHP 7.0.0 or later for long term
 191 support.
 192
 193 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 194 but support for them is somewhat less mature. There is experimental support for
 195 Oracle and Microsoft SQL Server.
 196
 197 The supported versions are:
 198
 199 * MySQL 5.5.8 or later
 200 * PostgreSQL 9.2 or later
 201 * SQLite 3.3.7 or later
 202 * Oracle 9.0.1 or later
 203 * Microsoft SQL Server 2005 (9.00.1399)
 204
 205 == Upgrading ==
 206 1.33 has several database changes since 1.32, and will not work without schema
 207 updates. Note that due to changes to some very large tables like the revision
 208 table, the schema update may take quite long (minutes on a medium sized site,
 209 many hours on a large site).
 210
 211 Don't forget to always back up your database before upgrading!
 212
 213 See the file UPGRADE for more detailed upgrade instructions, including
 214 important information when upgrading from versions prior to 1.11.
