   7 MediaWiki 1.34 is an alpha-quality development branch, and is not recommended
   8 for use in production.

  10 == Upgrading notes for 1.34 ==
  11 1.34 has several database changes since 1.33, and will not work without schema
  12 updates. Note that due to changes to some very large tables like the revision
  13 table, the schema update may take quite long (minutes on a medium sized site,
  14 many hours on a large site).
  15
  16 Don't forget to always back up your database before upgrading!
  17
  18 See the file UPGRADE for more detailed upgrade instructions, including
  19 important information when upgrading from versions prior to 1.11.

  70 === Breaking changes in 1.34 ===
  71 * Preferences class, deprecated in 1.31, has been removed.
  72 * The following parts of code, deprecated in 1.32, were removed in favor of
  73   built-in PHP functions:
  74   * CryptRand class
  75   * CryptRand service
  76   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  77 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  78   create a new Language object with a different language code.
  79 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  80   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  81   Instead, reset services, such as by calling $this->overrideMwServices() (if
  82   your test extends MediaWikiTestCase). Services will generally not pick up
  83   configuration changes from after they were created, so you must reset
  84   services after any configuration change. Even if your code works now, it is
  85   likely to break in future versions as more code is moved to services.
  86 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
  87 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
  88   been removed.
  89 * ObjectFactory class, deprecated in 1.31, has been removed.
  90
  91 === Deprecations in 1.34 ===
  92 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.
  93 * …

  97
  98 == Compatibility ==
  99 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 100 supported, it is generally advised to use PHP 7.0.13 or later for long term
 101 support.
 102
 103 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 104 but support for them is somewhat less mature. There is experimental support for
 105 Oracle and Microsoft SQL Server.
 106
 107 The supported versions are:
 108
 109 * MySQL 5.5.8 or later
 110 * PostgreSQL 9.2 or later
 111 * SQLite 3.8.0 or later
 112 * Oracle 9.0.1 or later
 113 * Microsoft SQL Server 2005 (9.00.1399)
