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

  61 * …
  62
  63 === Breaking changes in 1.33 ===
  64 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  65   Language. Other types are deprecated since 1.32.
  66 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  67   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  68   deprecated since 1.32.
  69 * Language::truncate(), deprecated in 1.31, has been removed.
  70 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  71   instead.
  72 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  73   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  74   use 'help', 'help-message', and 'help-messages'.
  75 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  76 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  77   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  78   Use the RESTBase v1 or Parsoid v3 API instead.
  79 * ParserOptions defaults 'tidy' to true now, since the untidy modes of the
  80   parser are being deprecated and ParserOptions::getCanonicalOverrides()
  81   has always been true at any rate.
  82 * A number of deprecated methods for API documentation, intended for overriding
  83   by extensions, are no longer called by MediaWiki, and will emit deprecation
  84   notices if your extension attempts to use them:
  85   * ApiBase::getDescription() (deprecated in 1.25)
  86   * ApiBase::getParamDescription() (deprecated in 1.25)
  87   * ApiBase::getExamples() (deprecated in 1.25)
  88   * ApiBase::getDescriptionMessage() (deprecated in 1.30)
  89   Additionally, the  'APIGetDescription' and 'APIGetParamDescription' hooks have
  90   been removed, as their only use was to let extensions override values returned
  91   by getDescription() and getParamDescription(), respectively.
  92 * …
  93
  94 === Deprecations in 1.33 ===
  95 * The configuration option $wgUseESI has been deprecated, and is expected
  96   to be removed in a future release.
  97 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
  98   and is expected to be removed in a future release.
  99 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
 100   introduced in MW 1.17, have been deprecated.  These fixes will always be
 101   applied for Arabic and Malayalam in the future.  Please enable these on
 102   your local wiki (if you have them explicitly set to false) and run
 103   maintenance/cleanupTitles.php to fix any existing page titles.
 104 * OutputPage::parse() and OutputPage::parseInline() have been deprecated
 105   due to untidy output and inconsistent handling of wrapper divs and
 106   interface/content language defaults.  Use OutputPage::parseAsContent(),
 107   OutputPage::parseAsInterface(), or OutputPage::parseInlineAsInterface()
 108   as appropriate.
 109 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
 110   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
 111   This will help identify the issue if you added it to $wgAuthManagerConfig.
 112 * wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
 113   domain ID as a key component and use makeGlobalKey().
 114 * …

 118
 119 == Compatibility ==
 120 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 121 supported, it is generally advised to use PHP 7.0.0 or later for long term
 122 support.
 123
 124 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 125 but support for them is somewhat less mature. There is experimental support for
 126 Oracle and Microsoft SQL Server.
 127
 128 The supported versions are:
 129
 130 * MySQL 5.5.8 or later
 131 * PostgreSQL 9.2 or later
 132 * SQLite 3.3.7 or later
 133 * Oracle 9.0.1 or later
 134 * Microsoft SQL Server 2005 (9.00.1399)
 135
 136 == Upgrading ==
 137 1.33 has several database changes since 1.32, and will not work without schema
 138 updates. Note that due to changes to some very large tables like the revision
 139 table, the schema update may take quite long (minutes on a medium sized site,
 140 many hours on a large site).
 141
 142 Don't forget to always back up your database before upgrading!
 143
 144 See the file UPGRADE for more detailed upgrade instructions, including
 145 important information when upgrading from versions prior to 1.11.
