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 * The AuthManagerLoginAuthenticateAudit hook has a new parameter for
  41   additional information about the authentication event.
  42 * …
  43
  44 === External library changes in 1.33 ===
  45
  46 ==== New external libraries ====
  47 * Added wikimedia/password-blacklist 0.1.4.
  48 * …
  49 * Added guzzlehttp/guzzle 6.3.3 and dependents:

  61 * …
  62
  63 ==== Removed external libraries ====
  64 * …
  65
  66 === Bug fixes in 1.33 ===
  67 * (T164211) Special:UserRights could sometimes fail with a
  68   "conflict detected" error when there weren't any conflicts.
  69 * …
  70
  71 === Action API changes in 1.33 ===
  72 * (T198913) Added 'ApiOptions' hook.
  73 * The JSON formatversion=2 is no longer experimental.
  74 * Internal API errors (those with code beginning "internal_api_error") will
  75   include the exception class name in a data field named "errorclass".
  76   * Class names are not guaranteed to remain stable, and in particular database
  77     exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
  78   * The code including an exception class name is deprecated. In the future,
  79     all internal errors will use code "internal_api_error".
  80 * (T212356) When using action=delete on pages with many revisions, the module
  81   may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
  82   deletion will be processed via the job queue.
  83
  84 === Action API internal changes in 1.33 ===
  85 * A number of deprecated methods for API documentation, intended for overriding
  86   by extensions, are no longer called by MediaWiki, and will emit deprecation
  87   notices if your extension attempts to use them:
  88   * ApiBase::getDescription() (deprecated in 1.25)
  89   * ApiBase::getParamDescription() (deprecated in 1.25)
  90   * ApiBase::getExamples() (deprecated in 1.25)
  91   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  92   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  93   been removed, as their only use was to let extensions override values returned
  94   by getDescription() and getParamDescription(), respectively.
  95 * API error codes may only contain ASCII letters, numbers, underscore, and
  96   hyphen. Methods such as ApiBase::dieWithError() and
  97   ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
  98   passed a bad code.
  99 * …
 100
 101 === Languages updated in 1.33 ===
 102 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 103 Below only new and removed languages are listed, as well as changes to languages
 104 because of Phabricator reports.
 105
 106 * (T203908) Added language support for Eastern Pwo (kjp).
 107
 108 === Breaking changes in 1.33 ===
 109 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
 110   Language. Other types are deprecated since 1.32.
 111 * Skin::doEditSectionLink requires type Language for the parameter $lang.
 112   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
 113   deprecated since 1.32.
 114 * Language::truncate(), deprecated in 1.31, has been removed.
 115 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
 116   instead.
 117 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
 118   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
 119   use 'help', 'help-message', and 'help-messages'.
 120 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
 121 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
 122   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
 123   Use the RESTBase v1 or Parsoid v3 API instead.
 124 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
 125   parser are being deprecated and ParserOptions::getCanonicalOverrides()
 126   has always been true at any rate.
 127 * Support for disabling tidy and external tidy implementations has been removed.
 128   This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
 129   used and no configuration is necessary.
 130 * A number of deprecated methods for API documentation, intended for overriding
 131   by extensions, are no longer called by MediaWiki, and will emit deprecation
 132   notices if your extension attempts to use them:
 133   * ApiBase::getDescription() (deprecated in 1.25)
 134   * ApiBase::getParamDescription() (deprecated in 1.25)
 135   * ApiBase::getExamples() (deprecated in 1.25)
 136   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
 137   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
 138   been removed, as their only use was to let extensions override values returned
 139   by getDescription() and getParamDescription(), respectively.
 140 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
 141   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
 142   the creation of AuthManager in 1.27, have been removed. This also means that
 143   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
 144   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
 145   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
 146 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 147   use 'jquery.i18n'.
 148 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 149   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 150   respectively in a $wgExtensionMessagesFiles file.
 151 * The following methods of the Preferences class, deprecated in 1.31, have been
 152   removed:
 153   * getSaveBlacklist()
 154   * loadPreferenceValues()
 155   * getOptionFromUser()
 156   * profilePreferences()
 157   * skinPreferences()
 158   * filesPreferences()

 161   * editingPreferences()
 162   * rcPreferences()
 163   * watchlistPreferences()
 164   * searchPreferences()
 165   * miscPreferences()
 166   * generateSkinOptions()
 167   * getDateOptions()
 168   * getImageSizes()
 169   * getThumbSizes()
 170   * validateSignature()
 171   * cleanSignature()
 172   * getTimezoneOptions()
 173   * filterIntval()
 174   * filterTimezoneInput()
 175   * getTimeZoneList()
 176 * mw.util.jsMessage(), deprecated in 1.20, was removed. Use mw.notify instead.
 177 * (T61113) User::EDIT_TOKEN_SUFFIX was removed. It was deprecated since 1.27.
 178
 179 === Deprecations in 1.33 ===
 180 * The configuration option $wgUseESI has been deprecated, and is expected
 181   to be removed in a future release.
 182 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 183   and is expected to be removed in a future release.
 184 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 185   introduced in MW 1.17, have been deprecated.  These fixes will always be
 186   applied for Arabic and Malayalam in the future.  Please enable these on
 187   your local wiki (if you have them explicitly set to false) and run
 188   maintenance/cleanupTitles.php to fix any existing page titles.
 189 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 190   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 191   This will help identify the issue if you added it to $wgAuthManagerConfig.
 192 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 193   domain ID as a key component and use makeGlobalKey().
 194 * (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
 195   Title::getDBKey(), which doesn't vary case.
 196 * User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
 197   returns the same information in a more useful format.
 198 * For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
 199   as the $lang parameter was deprecated. The same applies to DummyLinker.
 200 * The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
 201   follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
 202   instead which blacklists 100,000 commonly used passwords.
 203 * …
 204
 205 === Other changes in 1.33 ===
 206 * (T208871) The hard-coded Google search form on the database error page was
 207   removed.
 208 * (T201747) Html::openElement() warns if given an element name wiht a space
 209   in it.
 210 * …
 211
 212 == Compatibility ==
 213 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 214 supported, it is generally advised to use PHP 7.0.0 or later for long term
 215 support.
 216
 217 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 218 but support for them is somewhat less mature. There is experimental support for
 219 Oracle and Microsoft SQL Server.
 220
 221 The supported versions are:
 222
 223 * MySQL 5.5.8 or later
 224 * PostgreSQL 9.2 or later
 225 * SQLite 3.3.7 or later
 226 * Oracle 9.0.1 or later
 227 * Microsoft SQL Server 2005 (9.00.1399)
 228
 229 == Upgrading ==
 230 1.33 has several database changes since 1.32, and will not work without schema
 231 updates. Note that due to changes to some very large tables like the revision
 232 table, the schema update may take quite long (minutes on a medium sized site,
 233 many hours on a large site).
 234
 235 Don't forget to always back up your database before upgrading!
 236
 237 See the file UPGRADE for more detailed upgrade instructions, including
 238 important information when upgrading from versions prior to 1.11.
