   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!

  18 See the file UPGRADE for more detailed upgrade instructions, including
  19 important information when upgrading from versions prior to 1.11.

  71
  72 === Breaking changes in 1.34 ===
  73 * Preferences class, deprecated in 1.31, has been removed.
  74 * The following parts of code, deprecated in 1.32, were removed in favor of
  75   built-in PHP functions:
  76   * CryptRand class
  77   * CryptRand service
  78   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  79 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  80   create a new Language object with a different language code.
  81 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  82   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  83   Instead, reset services, such as by calling $this->overrideMwServices() (if
  84   your test extends MediaWikiTestCase). Services will generally not pick up
  85   configuration changes from after they were created, so you must reset
  86   services after any configuration change. Even if your code works now, it is
  87   likely to break in future versions as more code is moved to services.
  88 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
  89 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
  90   been removed.
  91 * ObjectFactory class, deprecated in 1.31, has been removed.
  92 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
  93 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
  94 * The RedirectSpecialPage::execute method could sometimes return a Title object.
  95   This behavior was removed, and the method now matches the parent signature
  96   (SpecialPage::execute) which is to return HTML string or void.
  97   To obtain the destination title, use RedirectSpecialPage::getRedirect.
  98 * The 'recenteditcount' response property from action API action=query
  99   list=allusers, deprecated in 1.25, has been removed.
 100 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 101   SearchEngine::create(), SearchEngine::getSearchTypes() and
 102   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed
 103
 104 === Deprecations in 1.34 ===
 105 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.

 111 == Compatibility ==
 112 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 113 supported, it is generally advised to use PHP 7.0.13 or later for long term
 114 support.
 115
 116 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 117 but support for them is somewhat less mature. There is experimental support for
 118 Oracle and Microsoft SQL Server.
 119
 120 The supported versions are:
 121
 122 * MySQL 5.5.8 or later
 123 * PostgreSQL 9.2 or later
 124 * SQLite 3.8.0 or later
 125 * Oracle 9.0.1 or later
 126 * Microsoft SQL Server 2005 (9.00.1399)
