   5 THIS IS NOT A RELEASE YET
   6
   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.

  60 === Action API changes in 1.34 ===
  61 * The 'recenteditcount' response property from action=query list=allusers,
  62   deprecated in 1.25, has been removed.
  63
  64 === Action API internal changes in 1.34 ===
  65 * …
  66
  67 === Languages updated in 1.34 ===
  68 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  69 Below only new and removed languages are listed, as well as changes to languages
  70 because of Phabricator reports.
  71
  72 * (T152908) Added language support for N'Ko (nqo).
  73
  74 === Breaking changes in 1.34 ===
  75 * Preferences class, deprecated in 1.31, has been removed.
  76 * The following parts of code, deprecated in 1.32, were removed in favor of
  77   built-in PHP functions:
  78   * CryptRand class
  79   * CryptRand service
  80   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  81 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  82   create a new Language object with a different language code.
  83 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  84   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  85   Instead, reset services, such as by calling $this->overrideMwServices() (if
  86   your test extends MediaWikiTestCase). Services will generally not pick up
  87   configuration changes from after they were created, so you must reset
  88   services after any configuration change. Even if your code works now, it is
  89   likely to break in future versions as more code is moved to services.
  90 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
  91 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
  92   been removed.
  93 * ObjectFactory class, deprecated in 1.31, has been removed.
  94 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
  95 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
  96 * The RedirectSpecialPage::execute method could sometimes return a Title object.
  97   This behavior was removed, and the method now matches the parent signature
  98   (SpecialPage::execute) which is to return HTML string or void.
  99   To obtain the destination title, use RedirectSpecialPage::getRedirect.
 100 * The 'recenteditcount' response property from action API action=query
 101   list=allusers, deprecated in 1.25, has been removed.
 102 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 103   SearchEngine::create(), SearchEngine::getSearchTypes() and
 104   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 105 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
 106 * User::randomPassword() method, deprecated in 1.27, have been removed.
 107 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.
 108 * Parser class property $mUniqPrefix, deprecated in 1.26, has been removed.
 109 * wfArrayFilter() and wfArrayFilterByKey(), deprecated in 1.32, have been
 110   removed.
 111 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 112 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 113   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 114 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 115   UserGroupMembership::getLink() instead.
 116 * …
 117
 118 === Deprecations in 1.34 ===
 119 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.
 120 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 121   Instead, use ->queue().
 122 * User::isBlocked() is deprecated since it does not tell you if the user is
 123   blocked from editing a particular page. Use User::getBlock() or
 124   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 125 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 126   to the BlockManager as private helper methods.
 127 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
 128   instead.
 129 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
 130   is deprecated. Pass only the User argument.
 131 * WatchedItem::getUser is deprecated. Use getUserIdentity.
 132 * Passing a Title as the first parameter to the getTimestampById method of
 133   RevisionStore is deprecated. Omit it, passing only the remaining parameters.
 134

 138 == Compatibility ==
 139 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 140 supported, it is generally advised to use PHP 7.0.13 or later for long term
 141 support.
 142
 143 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 144 but support for them is somewhat less mature. There is experimental support for
 145 Oracle and Microsoft SQL Server.
 146
 147 The supported versions are:
 148
 149 * MySQL 5.5.8 or later
 150 * PostgreSQL 9.2 or later
 151 * SQLite 3.8.0 or later
 152 * Oracle 9.0.1 or later
 153 * Microsoft SQL Server 2005 (9.00.1399)
