   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).
  36
  37 ==== Changed configuration ====

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

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

 130   removed.
 131 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 132 * Method signatures in WatchedItemQueryServiceExtension have changed from taking
 133   User objects to taking UserIdentity objects. Extensions implementing this
 134   interface need to be changed accordingly.
 135 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 136   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 137 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 138   UserGroupMembership::getLink() instead.
 139 * SavepointPostgres, deprecated in 1.31, has been removed.
 140 * Output::sectionEditLinksEnabled(), ParserOutput::getEditSectionTokens,
 141   ::getTOCEnabled, ::setEditSectionTokens, ::setTOCEnabled, deprecated in 1.31,
 142   have been removed.
 143 * EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
 144   have been removed.
 145 * Four methods in OutputPage, deprecated in 1.32, have been removed. You should
 146   use OutputPage::showFatalError or throw a FatalError instead. The methods are
 147   ::showFileCopyError(), ::showFileRenameError(), ::showFileDeleteError(), and
 148   ::showFileNotFoundError().
 149 * ApiBase::truncateArray(), deprecated in 1.32, has been removed.
 150 * IcuCollation::getICUVersion(), deprecated in 1.32, has been removed. Use PHP's
 151   INTL_ICU_VERSION constant directly.

 154   both deprecated in 1.32, have been removed.

 156   been removed. Use ->msg() or ->getMsg() instead.
 157 * WatchAction::getUnwatchToken(), deprecated in 1.32, has been removed. Instead,
 158   use WatchAction::getWatchToken() with action 'unwatch' directly.

 160   1.28, have been removed.

 170 * MediaWikiTestCase::stashMwGlobals(), deprecated in 1.32, has been removed.
 171 * SearchEngine::transformSearchTerm(), deprecated in 1.32, has been removed.
 172 * The Block typehint only refers to blocks stored in the database. It should be
 173   updated to AbstractBlock in cases where any type of block could be expected.
 174 * FileRepoStatus, deprecated in 1.25, has been removed.

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