  51 === Breaking changes in 1.33 ===
  52 * The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
  53   Language. Other types are deprecated since 1.32.
  54 * Skin::doEditSectionLink requires type Language for the parameter $lang.
  55   The parameters $tooltip and $lang are mandatory. Omitting the parameters is
  56   deprecated since 1.32.
  57 * Language::truncate(), deprecated in 1.31, has been removed.
  58 * UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
  59   instead.
  60 * (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
  61   and 'notice-message', which were deprecated in 1.32, were removed. Instead,
  62   use 'help', 'help-message', and 'help-messages'.
  63 * (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
  64 * The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
  65   RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
  66   Use the RESTBase v1 or Parsoid v3 API instead.
  67 * …
  68
  69 === Deprecations in 1.33 ===
  70 * The configuration option $wgUseESI has been deprecated, and is expected
  71   to be removed in a future release.
  72 * The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
  73   and is expected to be removed in a future release.
  74 * The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
  75   introduced in MW 1.17, have been deprecated.  These fixes will always be
  76   applied for Arabic and Malayalam in the future.  Please enable these on
  77   your local wiki (if you have them explicitly set to false) and run
  78   maintenance/cleanupTitles.php to fix any existing page titles.
  79 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation
  80   in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
  81   This will help identify the issue if you added it to $wgAuthManagerConfig.

  87 == Compatibility ==
  88 MediaWiki 1.33 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
  89 supported, it is generally advised to use PHP 7.0.0 or later for long term
  90 support.
  91
  92 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
  93 but support for them is somewhat less mature. There is experimental support for
  94 Oracle and Microsoft SQL Server.
  95
  96 The supported versions are:
  97
  98 * MySQL 5.5.8 or later
  99 * PostgreSQL 9.2 or later
 100 * SQLite 3.3.7 or later
 101 * Oracle 9.0.1 or later
 102 * Microsoft SQL Server 2005 (9.00.1399)
 103
 104 == Upgrading ==
 105 1.33 has several database changes since 1.32, and will not work without schema
 106 updates. Note that due to changes to some very large tables like the revision
 107 table, the schema update may take quite long (minutes on a medium sized site,
 108 many hours on a large site).
 109
 110 Don't forget to always back up your database before upgrading!
 111
 112 See the file UPGRADE for more detailed upgrade instructions, including
 113 important information when upgrading from versions prior to 1.11.
