   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.
   9
  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.

  57 === Bug fixes in 1.34 ===
  58 * (T222529) If a log entry or page revision is recorded in the database with an
  59   empty username, attempting to display it will log an error and return a "no
  60   username available" to the user instead of silently displaying nothing or
  61   invalid links.
  62
  63 === Action API changes in 1.34 ===
  64 * The 'recenteditcount' response property from action=query list=allusers,
  65   deprecated in 1.25, has been removed.
  66
  67 === Action API internal changes in 1.34 ===
  68 * …
  69
  70 === Languages updated in 1.34 ===
  71 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  72 Below only new and removed languages are listed, as well as changes to languages
  73 because of Phabricator reports.
  74
  75 * (T152908) Added language support for N'Ko (nqo).
  76
  77 === Breaking changes in 1.34 ===
  78 * Preferences class, deprecated in 1.31, has been removed.
  79 * The following parts of code, deprecated in 1.32, were removed in favor of
  80   built-in PHP functions:
  81   * CryptRand class
  82   * CryptRand service
  83   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  84 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  85   create a new Language object with a different language code.
  86 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  87   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  88   Instead, reset services, such as by calling $this->overrideMwServices() (if
  89   your test extends MediaWikiTestCase). Services will generally not pick up
  90   configuration changes from after they were created, so you must reset
  91   services after any configuration change. Even if your code works now, it is
  92   likely to break in future versions as more code is moved to services.
  93 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
  94 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
  95   been removed.
  96 * ObjectFactory class, deprecated in 1.31, has been removed.
  97 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
  98 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
  99 * The RedirectSpecialPage::execute method could sometimes return a Title object.
 100   This behavior was removed, and the method now matches the parent signature
 101   (SpecialPage::execute) which is to return HTML string or void.
 102   To obtain the destination title, use RedirectSpecialPage::getRedirect.
 103 * The 'recenteditcount' response property from action API action=query
 104   list=allusers, deprecated in 1.25, has been removed.
 105 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 106   SearchEngine::create(), SearchEngine::getSearchTypes() and
 107   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 108 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
 109 * User::randomPassword() method, deprecated in 1.27, have been removed.
 110 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.
 111 * Parser class property $mUniqPrefix, deprecated in 1.26, has been removed.
 112 * wfArrayFilter() and wfArrayFilterByKey(), deprecated in 1.32, have been
 113   removed.
 114 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 115 * Method signatures in WatchedItemQueryServiceExtension have changed from taking
 116   User objects to taking UserIdentity objects. Extensions implementing this
 117   interface need to be changed accordingly.
 118 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 119   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 120 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 121   UserGroupMembership::getLink() instead.
 122 * SavepointPostgres, deprecated in 1.31, has been removed.
 123 * Output::sectionEditLinksEnabled(), ParserOutput::getEditSectionTokens,
 124   ::getTOCEnabled, ::setEditSectionTokens, ::setTOCEnabled, deprecated in 1.31,
 125   have been removed.
 126 * EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
 127   have been removed.
 128 * …
 129
 130 === Deprecations in 1.34 ===
 131 * The MWNamespace class is deprecated. Use NamespaceInfo.
 132 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 133   Instead, use ->queue().
 134 * User::isBlocked() is deprecated since it does not tell you if the user is
 135   blocked from editing a particular page. Use User::getBlock() or
 136   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 137 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 138   to the BlockManager as private helper methods.
 139 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
 140   instead.
 141 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
 142   is deprecated. Pass only the User argument.
 143 * WatchedItem::getUser is deprecated. Use getUserIdentity.
 144 * Passing a Title as the first parameter to the getTimestampById method of
 145   RevisionStore is deprecated. Omit it, passing only the remaining parameters.
 146 * Title::getPreviousRevisionId and Title::getNextRevisionId are deprecated. Use
 147   RevisionLookup::getPreviousRevision and RevisionLookup::getNextRevision.
 148 * The Title parameter to RevisionLookup::getPreviousRevision and
 149   RevisionLookup::getNextRevision is deprecated and should be omitted.
 150 * MWHttpRequest::factory is deprecated. Use HttpRequestFactory.
 151 * The Http class is deprecated. For the request, get, and post methods, use
 152   HttpRequestFactory. For isValidURI, use MWHttpRequest::isValidURI.  For
 153   getProxy, use (string)$wgHTTPProxy. For createMultiClient, construct a
 154   MultiHttpClient directly.
 155 * Http::$httpEngine is deprecated and has no replacement. The default 'guzzle'
 156   engine will eventually be made the only engine for HTTP requests.
 157 * RepoGroup::singleton(), RepoGroup::destroySingleton(),
 158   RepoGroup::setSingleton(), wfFindFile(), and wfLocalFile() are all
 159   deprecated. Use MediaWikiServices instead.
 160 * The getSubjectPage, getTalkPage, and getOtherPage of Title are deprecated.
 161   Use NamespaceInfo's getSubjectPage, getTalkPage, and getAssociatedPage.
 162

 166 == Compatibility ==
 167 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is

 169 support.

 172 but support for them is somewhat less mature. There is experimental support for
 173 Oracle and Microsoft SQL Server.

 176
 177 * MySQL 5.5.8 or later
 178 * PostgreSQL 9.2 or later
