   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.

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