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

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