  41 * (T198913) Added 'ApiOptions' hook.
  42 * …
  43
  44 === Action API internal changes in 1.33 ===
  45 * A number of deprecated methods for API documentation, intended for overriding
  46   by extensions, are no longer called by MediaWiki, and will emit deprecation
  47   notices if your extension attempts to use them:
  48   * ApiBase::getDescription() (deprecated in 1.25)
  49   * ApiBase::getParamDescription() (deprecated in 1.25)
  50   * ApiBase::getExamples() (deprecated in 1.25)
  51   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  52   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  53   been removed, as their only use was to let extensions override values returned
  54   by getDescription() and getParamDescription(), respectively.
  55 * …
  56
  57 === Languages updated in 1.33 ===
  58 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  59 Below only new and removed languages are listed, as well as changes to languages
  60 because of Phabricator reports.

  62 * …
  63
  64 === Breaking changes in 1.33 ===
  65 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  66   Language. Other types are deprecated since 1.32.
  67 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  68   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  69   deprecated since 1.32.
  70 * Language::truncate(), deprecated in 1.31, has been removed.
  71 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  72   instead.
  73 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  74   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  75   use 'help', 'help-message', and 'help-messages'.
  76 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  77 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  78   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  79   Use the RESTBase v1 or Parsoid v3 API instead.
  80 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  81   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  82   has always been true at any rate.
  83 * A number of deprecated methods for API documentation, intended for overriding
  84   by extensions, are no longer called by MediaWiki, and will emit deprecation
  85   notices if your extension attempts to use them:
  86   * ApiBase::getDescription() (deprecated in 1.25)
  87   * ApiBase::getParamDescription() (deprecated in 1.25)
  88   * ApiBase::getExamples() (deprecated in 1.25)
  89   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  90   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  91   been removed, as their only use was to let extensions override values returned
  92   by getDescription() and getParamDescription(), respectively.
  93 * The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
  94   'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
  95   the creation of AuthManager in 1.27, have been removed. This also means that
  96   the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
  97   is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
  98   that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
  99 * The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
 100   use 'jquery.i18n'.
 101 * The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
 102   1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
 103   respectively in a $wgExtensionMessagesFiles file.
 104 * …
 105
 106 === Deprecations in 1.33 ===
 107 * The configuration option $wgUseESI has been deprecated, and is expected
 108   to be removed in a future release.
 109 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
 110   and is expected to be removed in a future release.
 111 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 112   introduced in MW 1.17, have been deprecated.  These fixes will always be
 113   applied for Arabic and Malayalam in the future.  Please enable these on
 114   your local wiki (if you have them explicitly set to false) and run
 115   maintenance/cleanupTitles.php to fix any existing page titles.
 116 * OutputPage::parse() and OutputPage::parseInline() have been deprecated
 117   due to untidy output and inconsistent handling of wrapper divs and
 118   interface/content language defaults.  Use OutputPage::parseAsContent(),
 119   OutputPage::parseAsInterface(), or OutputPage::parseInlineAsInterface()
 120   as appropriate.
 121 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 122   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 123   This will help identify the issue if you added it to $wgAuthManagerConfig.
 124 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 125   domain ID as a key component and use makeGlobalKey().
 126 * …

 128 === Other changes in 1.33 ===
 129 * …
 130
 131 == Compatibility ==
 132 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 133 supported, it is generally advised to use PHP 7.0.0 or later for long term
 134 support.
 135
 136 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 137 but support for them is somewhat less mature. There is experimental support for
 138 Oracle and Microsoft SQL Server.
 139
 140 The supported versions are:
 141
 142 * MySQL 5.5.8 or later
 143 * PostgreSQL 9.2 or later
 144 * SQLite 3.3.7 or later
 145 * Oracle 9.0.1 or later
 146 * Microsoft SQL Server 2005 (9.00.1399)
 147
 148 == Upgrading ==
 149 1.33 has several database changes since 1.32, and will not work without schema
 150 updates. Note that due to changes to some very large tables like the revision
 151 table, the schema update may take quite long (minutes on a medium sized site,
 152 many hours on a large site).
 153
 154 Don't forget to always back up your database before upgrading!
 155
 156 See the file UPGRADE for more detailed upgrade instructions, including
 157 important information when upgrading from versions prior to 1.11.
