   5 THIS IS NOT A RELEASE YET

   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.

  68
  69 === Breaking changes in 1.34 ===
  70 * Preferences class, deprecated in 1.31, has been removed.
  71 * The following parts of code, deprecated in 1.32, were removed in favor of
  72   built-in PHP functions:
  73   * CryptRand class
  74   * CryptRand service
  75   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  76 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  77   create a new Language object with a different language code.
  78 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  79   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  80   Instead, reset services, such as by calling $this->overrideMwServices() (if
  81   your test extends MediaWikiTestCase). Services will generally not pick up
  82   configuration changes from after they were created, so you must reset
  83   services after any configuration change. Even if your code works now, it is
  84   likely to break in future versions as more code is moved to services.
  85 * …
  86
  87 === Deprecations in 1.34 ===
  88 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.

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