   4
   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.

  63 === Bug fixes in 1.34 ===
  64 * (T222529) If a log entry or page revision is recorded in the database with an
  65   empty username, attempting to display it will log an error and return a "no
  66   username available" to the user instead of silently displaying nothing or
  67   invalid links.
  68
  69 === Action API changes in 1.34 ===
  70 * The 'recenteditcount' response property from action=query list=allusers,
  71   deprecated in 1.25, has been removed.
  72

  74 * …
  75
  76 === Languages updated in 1.34 ===
  77 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  78 Below only new and removed languages are listed, as well as changes to languages
  79 because of Phabricator reports.
  80
  81 * (T152908) Added language support for N'Ko (nqo).
  82
  83 === Breaking changes in 1.34 ===
  84 * Preferences class, deprecated in 1.31, has been removed.
  85 * The following parts of code, deprecated in 1.32, were removed in favor of
  86   built-in PHP functions:
  87   * CryptRand class
  88   * CryptRand service
  89   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  90 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
  91   create a new Language object with a different language code.
  92 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
  93   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
  94   Instead, reset services, such as by calling $this->overrideMwServices() (if
  95   your test extends MediaWikiTestCase). Services will generally not pick up
  96   configuration changes from after they were created, so you must reset
  97   services after any configuration change. Even if your code works now, it is
  98   likely to break in future versions as more code is moved to services.
  99 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
 100 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
 101   been removed.
 102 * ObjectFactory class, deprecated in 1.31, has been removed.
 103 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
 104 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
 105 * The RedirectSpecialPage::execute method could sometimes return a Title object.
 106   This behavior was removed, and the method now matches the parent signature
 107   (SpecialPage::execute) which is to return HTML string or void.
 108   To obtain the destination title, use RedirectSpecialPage::getRedirect.
 109 * The 'recenteditcount' response property from action API action=query
 110   list=allusers, deprecated in 1.25, has been removed.
 111 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 112   SearchEngine::create(), SearchEngine::getSearchTypes() and
 113   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 114 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
 115 * User::randomPassword() method, deprecated in 1.27, have been removed.
 116 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.
 117 * Parser class property $mUniqPrefix, deprecated in 1.26, has been removed.
 118 * wfArrayFilter() and wfArrayFilterByKey(), deprecated in 1.32, have been
 119   removed.
 120 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 121 * Method signatures in WatchedItemQueryServiceExtension have changed from taking
 122   User objects to taking UserIdentity objects. Extensions implementing this
 123   interface need to be changed accordingly.
 124 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 125   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 126 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 127   UserGroupMembership::getLink() instead.
 128 * SavepointPostgres, deprecated in 1.31, has been removed.
 129 * Output::sectionEditLinksEnabled(), ParserOutput::getEditSectionTokens,
 130   ::getTOCEnabled, ::setEditSectionTokens, ::setTOCEnabled, deprecated in 1.31,
 131   have been removed.
 132 * EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
 133   have been removed.
 134 * Four methods in OutputPage, deprecated in 1.32, have been removed. You should
 135   use OutputPage::showFatalError or throw a FatalError instead. The methods are
 136   ::showFileCopyError(), ::showFileRenameError(), ::showFileDeleteError(), and
 137   ::showFileNotFoundError().
 138 * ApiBase::truncateArray(), deprecated in 1.32, has been removed.
 139 * IcuCollation::getICUVersion(), deprecated in 1.32, has been removed. Use PHP's
 140   INTL_ICU_VERSION constant directly.
 141 * HTMLForm::setSubmitProgressive(), deprecated in 1.32, has been removed.
 142 * ResourceLoaderStartUpModules::getStartupModules() and ::getLegacyModules(),
 143   both deprecated in 1.32, have been removed.
 144 * BaseTemplate::msgHtml() and QuickTemplate::msgHtml(), deprecated in 1.32, have
 145   been removed. Use ->msg() or ->getMsg() instead.
 146 * WatchAction::getUnwatchToken(), deprecated in 1.32, has been removed. Instead,
 147   use WatchAction::getWatchToken() with action 'unwatch' directly.
 148 * Language::initEncoding(), ::recodeForEdit(), and recodeInput(), deprecated in
 149   1.28, have been removed.
 150 * PageArchive::getTextFromRow(), ::listAllPages(), and ::getLastRevisionText(),
 151   deprecated in 1.32, have been removed.

 153   in 1.33, have been removed.

 156   removed.
 157 * ChangeTags::purgeTagUsageCache(), deprecated in 1.33, has been removed.
 158 * JobQueueGroup::pushLazyJobs(), deprecated in 1.33, has been removed.
 159 * MediaWikiTestCase::stashMwGlobals(), deprecated in 1.32, has been removed.
 160 * SearchEngine::transformSearchTerm(), deprecated in 1.32, has been removed.
 161 * …
 162
 163 === Deprecations in 1.34 ===
 164 * The MWNamespace class is deprecated. Use NamespaceInfo.
 165 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 166   Instead, use ->queue().
 167 * User::isBlocked() is deprecated since it does not tell you if the user is
 168   blocked from editing a particular page. Use User::getBlock() or
 169   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 170 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 171   to the BlockManager as private helper methods.
 172 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
 173   instead.
 174 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
 175   is deprecated. Pass only the User argument.
 176 * WatchedItem::getUser is deprecated. Use getUserIdentity.
 177 * Passing a Title as the first parameter to the getTimestampById method of
 178   RevisionStore is deprecated. Omit it, passing only the remaining parameters.
 179 * Title::getPreviousRevisionId and Title::getNextRevisionId are deprecated. Use
 180   RevisionLookup::getPreviousRevision and RevisionLookup::getNextRevision.
 181 * The Title parameter to RevisionLookup::getPreviousRevision and
 182   RevisionLookup::getNextRevision is deprecated and should be omitted.
 183 * MWHttpRequest::factory is deprecated. Use HttpRequestFactory.
 184 * The Http class is deprecated. For the request, get, and post methods, use
 185   HttpRequestFactory. For isValidURI, use MWHttpRequest::isValidURI.  For
 186   getProxy, use (string)$wgHTTPProxy. For createMultiClient, construct a
 187   MultiHttpClient directly.
 188 * Http::$httpEngine is deprecated and has no replacement. The default 'guzzle'
 189   engine will eventually be made the only engine for HTTP requests.
 190 * RepoGroup::singleton(), RepoGroup::destroySingleton(),
 191   RepoGroup::setSingleton(), wfFindFile(), and wfLocalFile() are all
 192   deprecated. Use MediaWikiServices instead.
 193 * The getSubjectPage, getTalkPage, and getOtherPage of Title are deprecated.
 194   Use NamespaceInfo's getSubjectPage, getTalkPage, and getAssociatedPage.
 195 * MWMessagePack class, no longer used, has been deprecated in 1.34.
