   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.

  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 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
  91 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
  92 * The RedirectSpecialPage::execute method could sometimes return a Title object.
  93   This behavior was removed, and the method now matches the parent signature
  94   (SpecialPage::execute) which is to return HTML string or void.
  95   To obtain the destination title, use RedirectSpecialPage::getRedirect.
  96
  97 === Deprecations in 1.34 ===
  98 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.

 104 == Compatibility ==
 105 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 106 supported, it is generally advised to use PHP 7.0.13 or later for long term
 107 support.
 108
 109 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 110 but support for them is somewhat less mature. There is experimental support for
 111 Oracle and Microsoft SQL Server.
 112
 113 The supported versions are:
 114
 115 * MySQL 5.5.8 or later
 116 * PostgreSQL 9.2 or later
 117 * SQLite 3.8.0 or later
 118 * Oracle 9.0.1 or later
 119 * Microsoft SQL Server 2005 (9.00.1399)
