   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.

  59 === Action API changes in 1.34 ===

  61   deprecated in 1.25, has been removed.
  62
  63 === Action API internal changes in 1.34 ===
  64 * …
  65
  66 === Languages updated in 1.34 ===
  67 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  68 Below only new and removed languages are listed, as well as changes to languages
  69 because of Phabricator reports.
  70
  71 * (T152908) Added language support for N'Ko (nqo).
  72
  73 === Breaking changes in 1.34 ===
  74 * Preferences class, deprecated in 1.31, has been removed.
  75 * The following parts of code, deprecated in 1.32, were removed in favor of
  76   built-in PHP functions:
  77   * CryptRand class
  78   * CryptRand service
  79   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  80 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  81   create a new Language object with a different language code.
  82 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  83   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  84   Instead, reset services, such as by calling $this->overrideMwServices() (if
  85   your test extends MediaWikiTestCase). Services will generally not pick up
  86   configuration changes from after they were created, so you must reset
  87   services after any configuration change. Even if your code works now, it is
  88   likely to break in future versions as more code is moved to services.
  89 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
  90 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
  91   been removed.
  92 * ObjectFactory class, deprecated in 1.31, has been removed.
  93 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
  94 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
  95 * The RedirectSpecialPage::execute method could sometimes return a Title object.
  96   This behavior was removed, and the method now matches the parent signature
  97   (SpecialPage::execute) which is to return HTML string or void.
  98   To obtain the destination title, use RedirectSpecialPage::getRedirect.
  99 * The 'recenteditcount' response property from action API action=query
 100   list=allusers, deprecated in 1.25, has been removed.
 101 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 102   SearchEngine::create(), SearchEngine::getSearchTypes() and
 103   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 104 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
 105 * User::randomPassword() method, deprecated in 1.27, have been removed.
 106 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.
 107 * Parser class property $mUniqPrefix, deprecated in 1.26, has been removed.
 108 * wfArrayFilter() and wfArrayFilterByKey(), deprecated in 1.32, have been
 109   removed.
 110 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 111 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 112   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 113 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 114   UserGroupMembership::getLink() instead.
 115 * …
 116
 117 === Deprecations in 1.34 ===
 118 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.
 119 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 120   Instead, use ->queue().
 121 * User::isBlocked() is deprecated since it does not tell you if the user is
 122   blocked from editing a particular page. Use User::getBlock() or
 123   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 124 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 125   to the BlockManager as private helper methods.
 126 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
 127   instead.
 128 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
 129   is deprecated. Pass only the User argument.

 134 == Compatibility ==
 135 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 136 supported, it is generally advised to use PHP 7.0.13 or later for long term
 137 support.

 139 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 140 but support for them is somewhat less mature. There is experimental support for
 141 Oracle and Microsoft SQL Server.
 142
 143 The supported versions are:
 144
 145 * MySQL 5.5.8 or later
 146 * PostgreSQL 9.2 or later
 147 * SQLite 3.8.0 or later
 148 * Oracle 9.0.1 or later
