RELEASE-NOTES-1.33

   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 * (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
  38   to be hidden on Special:UnusedCategories.
  39 * Add PasswordPolicy to check the password isn't in the large blacklist.
  40 * …
  41

  64 === Bug fixes in 1.33 ===
  65 * …
  66
  67 === Action API changes in 1.33 ===
  68 * (T198913) Added 'ApiOptions' hook.
  69 * The JSON formatversion=2 is no longer experimental.
  70 * Internal API errors (those with code beginning "internal_api_error") will
  71   include the exception class name in a data field named "errorclass".
  72   * Class names are not guaranteed to remain stable, and in particular database
  73     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  74   * The code including an exception class name is deprecated. In the future,
  75     all internal errors will use code "internal_api_error".
  76 * …
  77
  78 === Action API internal changes in 1.33 ===
  79 * A number of deprecated methods for API documentation, intended for overriding
  80   by extensions, are no longer called by MediaWiki, and will emit deprecation
  81   notices if your extension attempts to use them:
  82   * ApiBase::getDescription() (deprecated in 1.25)
  83   * ApiBase::getParamDescription() (deprecated in 1.25)
  84   * ApiBase::getExamples() (deprecated in 1.25)
  85   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  86   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  87   been removed, as their only use was to let extensions override values returned
  88   by getDescription() and getParamDescription(), respectively.
  89 * API error codes may only contain ASCII letters, numbers, underscore, and
  90   hyphen. Methods such as ApiBase::dieWithError() and
  91   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  92   passed a bad code.
  93 * …
  94
  95 === Languages updated in 1.33 ===
  96 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  97 Below only new and removed languages are listed, as well as changes to languages
  98 because of Phabricator reports.
  99
 100 * (T203908) Added language support for Eastern Pwo (kjp).
 101
 102 === Breaking changes in 1.33 ===
 103 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 104   Language. Other types are deprecated since 1.32.
 105 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 106   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 107   deprecated since 1.32.
 108 * Language::truncate(), deprecated in 1.31, has been removed.
 109 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 110   instead.
 111 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 112   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 113   use 'help', 'help-message', and 'help-messages'.
 114 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 115 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 116   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 117   Use the RESTBase v1 or Parsoid v3 API instead.
 118 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 119   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 120   has always been true at any rate.
 121 * Support for disabling tidy and external tidy implementations has been removed.
 122   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 123   used and no configuration is necessary.
 124 * A number of deprecated methods for API documentation, intended for overriding
 125   by extensions, are no longer called by MediaWiki, and will emit deprecation
 126   notices if your extension attempts to use them:
 127   * ApiBase::getDescription() (deprecated in 1.25)
 128   * ApiBase::getParamDescription() (deprecated in 1.25)
 129   * ApiBase::getExamples() (deprecated in 1.25)
 130   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 131   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 132   been removed, as their only use was to let extensions override values returned
 133   by getDescription() and getParamDescription(), respectively.
 134 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 135   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 136   the creation of AuthManager in 1.27, have been removed. This also means that
 137   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 138   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 139   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 140 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 141   use 'jquery.i18n'.
 142 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 143   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 144   respectively in a $wgExtensionMessagesFiles file.
 145 * The following methods of the Preferences class, deprecated in 1.31, have been
 146   removed:
 147   * getSaveBlacklist()
 148   * loadPreferenceValues()
 149   * getOptionFromUser()
 150   * profilePreferences()
 151   * skinPreferences()
 152   * filesPreferences()
 153   * datetimePreferences()
 154   * renderingPreferences()
 155   * editingPreferences()
 156   * rcPreferences()
 157   * watchlistPreferences()
 158   * searchPreferences()
 159   * miscPreferences()
 160   * generateSkinOptions()
 161   * getDateOptions()
 162   * getImageSizes()
 163   * getThumbSizes()
 164   * validateSignature()
 165   * cleanSignature()
 166   * getTimezoneOptions()
 167   * filterIntval()
 168   * filterTimezoneInput()
 169   * getTimeZoneList()
 170 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 171 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 172
 173 === Deprecations in 1.33 ===
 174 * The configuration option $wgUseESI has been deprecated, and is expected
 175   to be removed in a future release.
 176 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 177   and is expected to be removed in a future release.
 178 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 179   introduced in MW 1.17, have been deprecated.  These fixes will always be
 180   applied for Arabic and Malayalam in the future.  Please enable these on
 181   your local wiki (if you have them explicitly set to false) and run
 182   maintenance/cleanupTitles.php to fix any existing page titles.
 183 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 184   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 185   This will help identify the issue if you added it to $wgAuthManagerConfig.
 186 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 187   domain ID as a key component and use makeGlobalKey().
 188 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 189   Title::getDBKey(), which doesn't vary case.
 190 * …
 191
 192 === Other changes in 1.33 ===
 193 * (T208871) The hard-coded Google search form on the database error page was
 194   removed.
 195 * …
 196
 197 == Compatibility ==
 198 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 199 supported, it is generally advised to use PHP 7.0.0 or later for long term
 200 support.
 201
 202 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 203 but support for them is somewhat less mature. There is experimental support for
 204 Oracle and Microsoft SQL Server.
 205
 206 The supported versions are:
 207
 208 * MySQL 5.5.8 or later
 209 * PostgreSQL 9.2 or later
 210 * SQLite 3.3.7 or later
 211 * Oracle 9.0.1 or later
 212 * Microsoft SQL Server 2005 (9.00.1399)
 213
 214 == Upgrading ==
 215 1.33 has several database changes since 1.32, and will not work without schema
 216 updates. Note that due to changes to some very large tables like the revision
 217 table, the schema update may take quite long (minutes on a medium sized site,
 218 many hours on a large site).
 219
 220 Don't forget to always back up your database before upgrading!
 221
 222 See the file UPGRADE for more detailed upgrade instructions, including
 223 important information when upgrading from versions prior to 1.11.
