   3 == MediaWiki 1.34.0-PRERELEASE ==
   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.

  27 === Configuration changes for system administrators in 1.34 ===
  28
  29 ==== New configuration ====
  30 * $wgAllowExternalReqID (T201409) - This configuration setting controls whether
  31   Mediawiki accepts the request ID set by the incoming request via the
  32   `X-Request-Id` header. If set to `true`, that value will be used throughout
  33   the code as the request identificator. Otherwise, the sent header will be
  34   ignored and the request ID will either be taken from Apache's mod_unique
  35   module or will be generated by Mediawiki itself (depending on the set-up).

  69 === Bug fixes in 1.34 ===
  70 * (T222529) If a log entry or page revision is recorded in the database with an
  71   empty username, attempting to display it will log an error and return a "no
  72   username available" to the user instead of silently displaying nothing or
  73   invalid links.
  74
  75 === Action API changes in 1.34 ===
  76 * The 'recenteditcount' response property from action=query list=allusers,
  77   deprecated in 1.25, has been removed.

  80 * …
  81
  82 === Languages updated in 1.34 ===
  83 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  84 Below only new and removed languages are listed, as well as changes to languages
  85 because of Phabricator reports.
  86
  87 * (T152908) Added language support for N'Ko (nqo).
  88
  89 === Breaking changes in 1.34 ===
  90 * The global functions wfSuppressWarnings and wfRestoreWarnings, deprecated in
  91   1.26, have been removed. Use Wikimedia\AtEase\AtEase::suppressWarnings() and
  92   Wikimedia\AtEase\AtEase::restoreWarnings() directly.
  93 * Preferences class, deprecated in 1.31, has been removed.
  94 * The following parts of code, deprecated in 1.32, were removed in favor of
  95   built-in PHP functions:
  96   * CryptRand class
  97   * CryptRand service
  98   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
  99 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
 100   create a new Language object with a different language code.
 101 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
 102   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
 103   Instead, reset services, such as by calling $this->overrideMwServices() (if
 104   your test extends MediaWikiTestCase). Services will generally not pick up
 105   configuration changes from after they were created, so you must reset
 106   services after any configuration change. Even if your code works now, it is
 107   likely to break in future versions as more code is moved to services.
 108 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
 109 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
 110   been removed.
 111 * ObjectFactory class, deprecated in 1.31, has been removed.
 112 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
 113 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
 114 * The RedirectSpecialPage::execute method could sometimes return a Title object.
 115   This behavior was removed, and the method now matches the parent signature
 116   (SpecialPage::execute) which is to return HTML string or void.
 117   To obtain the destination title, use RedirectSpecialPage::getRedirect.
 118 * The 'recenteditcount' response property from action API action=query
 119   list=allusers, deprecated in 1.25, has been removed.
 120 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 121   SearchEngine::create(), SearchEngine::getSearchTypes() and
 122   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 123 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
 124 * User::randomPassword() method, deprecated in 1.27, have been removed.
 125 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.

 128   removed.
 129 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 130 * Method signatures in WatchedItemQueryServiceExtension have changed from taking
 131   User objects to taking UserIdentity objects. Extensions implementing this
 132   interface need to be changed accordingly.
 133 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 134   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 135 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 136   UserGroupMembership::getLink() instead.
 137 * SavepointPostgres, deprecated in 1.31, has been removed.
 138 * Output::sectionEditLinksEnabled(), ParserOutput::getEditSectionTokens,
 139   ::getTOCEnabled, ::setEditSectionTokens, ::setTOCEnabled, deprecated in 1.31,
 140   have been removed.
 141 * EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
 142   have been removed.
 143 * Four methods in OutputPage, deprecated in 1.32, have been removed. You should
 144   use OutputPage::showFatalError or throw a FatalError instead. The methods are
 145   ::showFileCopyError(), ::showFileRenameError(), ::showFileDeleteError(), and
 146   ::showFileNotFoundError().
 147 * ApiBase::truncateArray(), deprecated in 1.32, has been removed.
 148 * IcuCollation::getICUVersion(), deprecated in 1.32, has been removed. Use PHP's
 149   INTL_ICU_VERSION constant directly.
 150 * HTMLForm::setSubmitProgressive(), deprecated in 1.32, has been removed.
 151 * ResourceLoaderStartUpModules::getStartupModules() and ::getLegacyModules(),
 152   both deprecated in 1.32, have been removed.
 153 * BaseTemplate::msgHtml() and QuickTemplate::msgHtml(), deprecated in 1.32, have
 154   been removed. Use ->msg() or ->getMsg() instead.
 155 * WatchAction::getUnwatchToken(), deprecated in 1.32, has been removed. Instead,
 156   use WatchAction::getWatchToken() with action 'unwatch' directly.
 157 * Language::initEncoding(), ::recodeForEdit(), and recodeInput(), deprecated in
 158   1.28, have been removed.
 159 * PageArchive::getTextFromRow(), ::listAllPages(), and ::getLastRevisionText(),

 167 * JobQueueGroup::pushLazyJobs(), deprecated in 1.33, has been removed.
 168 * MediaWikiTestCase::stashMwGlobals(), deprecated in 1.32, has been removed.
 169 * SearchEngine::transformSearchTerm(), deprecated in 1.32, has been removed.
 170 * The Block typehint only refers to blocks stored in the database. It should be
 171   updated to AbstractBlock in cases where any type of block could be expected.
 172 * FileRepoStatus, deprecated in 1.25, has been removed.
 173 * The LegacyHookPreAuthenticationProvider class, deprecated since its creation

 178 * …
 179
 180 === Deprecations in 1.34 ===
 181 * The MWNamespace class is deprecated. Use NamespaceInfo.
 182 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 183   Instead, use ->queue().
 184 * User::isBlocked() is deprecated since it does not tell you if the user is
 185   blocked from editing a particular page. Use User::getBlock() or
 186   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 187 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 188   to the BlockManager as private helper methods.
 189 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
 190   instead.
 191 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
 192   is deprecated. Pass only the User argument.
 193 * WatchedItem::getUser is deprecated. Use getUserIdentity.
 194 * Passing a Title as the first parameter to the getTimestampById method of
 195   RevisionStore is deprecated. Omit it, passing only the remaining parameters.
 196 * Title::getPreviousRevisionId and Title::getNextRevisionId are deprecated. Use
 197   RevisionLookup::getPreviousRevision and RevisionLookup::getNextRevision.
 198 * The Title parameter to RevisionLookup::getPreviousRevision and
 199   RevisionLookup::getNextRevision is deprecated and should be omitted.
 200 * MWHttpRequest::factory is deprecated. Use HttpRequestFactory.
 201 * The Http class is deprecated. For the request, get, and post methods, use
 202   HttpRequestFactory. For isValidURI, use MWHttpRequest::isValidURI.  For
 203   getProxy, use (string)$wgHTTPProxy. For createMultiClient, construct a
 204   MultiHttpClient directly.
 205 * Http::$httpEngine is deprecated and has no replacement. The default 'guzzle'
 206   engine will eventually be made the only engine for HTTP requests.
 207 * RepoGroup::singleton(), RepoGroup::destroySingleton(),
 208   RepoGroup::setSingleton(), wfFindFile(), and wfLocalFile() are all
 209   deprecated. Use MediaWikiServices instead.
 210 * The getSubjectPage, getTalkPage, and getOtherPage of Title are deprecated.
 211   Use NamespaceInfo's getSubjectPage, getTalkPage, and getAssociatedPage.
 212 * MWMessagePack class, no longer used, has been deprecated in 1.34.
 213 * The Block class is separated into Block (for blocks stored in the database),
 214   and SystemBlock (for temporary blocks created by the system). SystemBlock
 215   should be used when creating any temporary blocks.
 216 * Parser::$mConf is deprecated. It will be removed entirely in a later version.
 217 * Constructing Parser directly is deprecated. Obtain one from ParserFactory.
