   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.

  25 For notes on 1.33.x and older releases, see HISTORY.
  26
  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 * $wgEnableSpecialMute (T218265) - This configuration controls whether
  37   Special:Mute is available and whether to include a link to it on emails
  38   originating from Special:Email.
  39 * editmyuserjsredirect user right – users without this right now cannot edit JS
  40   redirects in their userspace unless the target of the redirect is also in
  41   their userspace. By default, this right is given to everyone.
  42
  43 ==== Changed configuration ====
  44 * $wgUseCdn, $wgCdnServers, $wgCdnServersNoPurge, and $wgCdnMaxAge – These four
  45   CDN-related config variables have been renamed from being specific to Squid –
  46   they were previously $wgUseSquid, $wgSquidServers, $wgSquidServersNoPurge, and
  47   $wgSquidMaxage respectively. This aligns them with the related existing
  48   variable $wgCdnMaxageLagged. The previous configuration variable names are
  49   deprecated, but will be used as the fall back if they are still set.
  50   Note that wgSquidPurgeUseHostHeader has not been renamed, as it is deprecated.
  51 * (T27707) File type checks for image uploads have been relaxed to allow files
  52   containing some HTML markup in metadata. As a result, the $wgAllowTitlesInSVG
  53   setting is no longer applied and is now always true. Note that MSIE 7 may
  54   still be able to misinterpret certain malformed PNG files as HTML.
  55 * Introduced $wgVerifyMimeTypeIE to allow disabling the MSIE 6/7 file type
  56   detection heuristic on upload, which is more conservative than the checks
  57   that were changed above.
  58 * $wgSkipSkin — Setting this instead of $wgSkipSkins, deprecated in 1.23, is now
  59   hard-deprecated.
  60 * $wgLocalInterwiki — Setting this instead of $wgLocalInterwikis, deprecated in
  61   1.23, is now hard-deprecated.
  62 * $wgProfileOnly — Setting this, deprecated in 1.23, is now hard-deprecated.
  63   Instead, set the log file in $wgDebugLogGroups['profileoutput'].
  64 * …
  65
  66 ==== Removed configuration ====
  67 * $wgWikiDiff2MovedParagraphDetectionCutoff — If you still want a custom change
  68   size threshold, please specify in php.ini, using the configuration variable
  69   wikidiff2.moved_paragraph_detection_cutoff.
  70 * $wgDebugPrintHttpHeaders - The default of including HTTP headers in the
  71   debug log channel is no longer configurable. The debug log itself remains
  72   configurable via $wgDebugLogFile.
  73 * $wgPasswordSalt – This setting, used for migrating exceptionally old, insecure
  74   password setups and deprecated since 1.24, is now removed.
  75
  76 === New user-facing features in 1.34 ===
  77 * Special:Mute has been added as a quick way for users to block unwanted emails
  78   from other users originating from Special:EmailUser.
  79
  80 === New developer features in 1.34 ===
  81 * The ImgAuthModifyHeaders hook was added to img_auth.php to allow modification
  82   of headers in private wikis.
  83 * Language::formatTimePeriod now supports the new 'avoidhours' option to output
  84   strings like "5 days ago" instead of "5 days 13 hours ago".
  85 * (T220163) Added SpecialMuteModifyFormFields hook to allow extensions
  86   to add fields to Special:Mute.
  87

 111 * …
 112
 113 === Bug fixes in 1.34 ===
 114 * (T222529) If a log entry or page revision is recorded in the database with an
 115   empty username, attempting to display it will log an error and return a "no
 116   username available" to the user instead of silently displaying nothing or
 117   invalid links.
 118
 119 === Action API changes in 1.34 ===
 120 * The 'recenteditcount' response property from action=query list=allusers,
 121   deprecated in 1.25, has been removed.
 122
 123 === Action API internal changes in 1.34 ===
 124 * …
 125
 126 === Languages updated in 1.34 ===
 127 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 128 Below only new and removed languages are listed, as well as changes to languages
 129 because of Phabricator reports.
 130
 131 * (T152908) Added language support for N'Ko (nqo).
 132
 133 === Breaking changes in 1.34 ===
 134 * The global functions wfSuppressWarnings and wfRestoreWarnings, deprecated in
 135   1.26, have been removed. Use Wikimedia\AtEase\AtEase::suppressWarnings() and
 136   Wikimedia\AtEase\AtEase::restoreWarnings() directly.
 137 * Preferences class, deprecated in 1.31, has been removed.
 138 * The following parts of code, deprecated in 1.32, were removed in favor of
 139   built-in PHP functions:
 140   * CryptRand class
 141   * CryptRand service
 142   * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
 143 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
 144   create a new Language object with a different language code.
 145 * MWNamespace::clearCaches() has been removed.  So has the $rebuild parameter
 146   to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
 147   Instead, reset services, such as by calling $this->overrideMwServices() (if
 148   your test extends MediaWikiTestCase). Services will generally not pick up
 149   configuration changes from after they were created, so you must reset
 150   services after any configuration change. Even if your code works now, it is
 151   likely to break in future versions as more code is moved to services.
 152 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
 153 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
 154   been removed.
 155 * ObjectFactory class, deprecated in 1.31, has been removed.

 157 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
 158 * The RedirectSpecialPage::execute method could sometimes return a Title object.
 159   This behavior was removed, and the method now matches the parent signature
 160   (SpecialPage::execute) which is to return HTML string or void.
 161   To obtain the destination title, use RedirectSpecialPage::getRedirect.
 162 * The 'recenteditcount' response property from action API action=query
 163   list=allusers, deprecated in 1.25, has been removed.
 164 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
 165   SearchEngine::create(), SearchEngine::getSearchTypes() and
 166   SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
 167 * FileRepo::streamFile(), deprecated in 1.26, has been removed.

 173 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
 174 * Method signatures in WatchedItemQueryServiceExtension have changed from taking
 175   User objects to taking UserIdentity objects. Extensions implementing this
 176   interface need to be changed accordingly.
 177 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
 178   removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
 179 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
 180   UserGroupMembership::getLink() instead.
 181 * SavepointPostgres, deprecated in 1.31, has been removed.

 183   ParserOptions::getEditSection(), ParserOptions::setEditSection(), and

 185   and ::setTOCEnabled, deprecated in 1.31, have been removed.
 186 * EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
 187   have been removed.
 188 * Four methods in OutputPage, deprecated in 1.32, have been removed. You should
 189   use OutputPage::showFatalError or throw a FatalError instead. The methods are
 190   ::showFileCopyError(), ::showFileRenameError(), ::showFileDeleteError(), and
 191   ::showFileNotFoundError().
 192 * ApiBase::truncateArray(), deprecated in 1.32, has been removed.

 275 * Database::reportConnectionError, deprecated in 1.32, has been removed.
 276 * APIEditBeforeSave hook, deprecated in 1.28, has been removed. Please see

 282 * The JavaScript global variable wgLoadScript has been removed. Use
 283   mw.util.wikiScript( 'load' ) instead.
 284 * ResourceLoader no longer creates the 'mw.legacy' placeholder object. It has
 285   been unused since 1.16 and was deprecated in 1.22. To deprecate a property
 286   in JavaScript, use mw.log.deprecate() instead.
 287 * The 'user.groups' module, deprecated in 1.28, was removed.

 301   updated since 2013 to cope with this deprecation may now break.
 302 * (T222637) Passing ResourceLoaderModule objects to ResourceLoader::register()
 303   or $wgResourceModules is no longer supported.
 304   Use the 'class' or 'factory' option of the array format instead.

 316
 317 === Deprecations in 1.34 ===
 318 * The MWNamespace class is deprecated. Use NamespaceInfo.
 319 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
 320   Instead, use ->queue().
 321 * User::isBlocked() is deprecated since it does not tell you if the user is
 322   blocked from editing a particular page. Use User::getBlock() or
 323   PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
 324 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
 325   to the BlockManager as private helper methods.

 330 * WatchedItem::getUser is deprecated. Use getUserIdentity.
 331 * Passing a Title as the first parameter to the getTimestampById method of
 332   RevisionStore is deprecated. Omit it, passing only the remaining parameters.

 334   RevisionLookup::getPreviousRevision and RevisionLookup::getNextRevision.
 335 * The Title parameter to RevisionLookup::getPreviousRevision and
 336   RevisionLookup::getNextRevision is deprecated and should be omitted.
 337 * MWHttpRequest::factory is deprecated. Use HttpRequestFactory.
 338 * The Http class is deprecated. For the request, get, and post methods, use
 339   HttpRequestFactory. For isValidURI, use MWHttpRequest::isValidURI.  For
 340   getProxy, use (string)$wgHTTPProxy. For createMultiClient, construct a
 341   MultiHttpClient directly.
 342 * Http::$httpEngine is deprecated and has no replacement. The default 'guzzle'
 343   engine will eventually be made the only engine for HTTP requests.
 344 * RepoGroup::singleton(), RepoGroup::destroySingleton(),
 345   RepoGroup::setSingleton(), wfFindFile(), and wfLocalFile() are all
 346   deprecated. Use MediaWikiServices instead.
 347 * The getSubjectPage, getTalkPage, and getOtherPage of Title are deprecated.
 348   Use NamespaceInfo's getSubjectPage, getTalkPage, and getAssociatedPage.
 349 * MWMessagePack class, no longer used, has been deprecated in 1.34.
 350 * The Block class is separated into DatabaseBlock (for blocks stored in the
 351   database), and SystemBlock (for temporary blocks created by the system).
 352   SystemBlock should be used when creating any temporary blocks. Block is
 353   a deprecated alias for DatabaseBlock.
 354 * Parser::$mConf is deprecated. It will be removed entirely in a later version.
 355   Some context can be found at T224165.
 356 * Constructing Parser directly is deprecated. Obtain one from ParserFactory.
 357 * Title::moveSubpages is deprecated. Use MovePage::moveSubpages or
 358   MovePage::moveSubpagesIfAllowed.
 359 * The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.
 360 * (T62260) Hard deprecate Language::getExtraUserToggles() method.
 361 * Language::viewPrevNext function is deprecated, use
 362   PrevNextNavigationRenderer::buildPrevNextNavigation instead
 363 * User::trackBlockWithCookie and DatabaseBlock::clearCookie are deprecated. Use
 364   BlockManager::trackBlockWithCookie and BlockManager::clearCookie instead.
 365 * DatabaseBlock::setCookie, DatabaseBlock::getCookieValue,
 366   DatabaseBlock::getIdFromCookieValue and AbstractBlock::shouldTrackWithCookie
 367   are moved to internal helper methods for BlockManager::trackBlockWithCookie.
 368 * ResourceLoaderContext::getConfig and ResourceLoaderContext::getLogger have
 369   been deprecated. Inside ResourceLoaderModule subclasses, use the local methods
 370   instead. Elsewhere, use the methods from the ResourceLoader class.
 371 * The Preprocessor_DOM implementation has been deprecated.  It will be
 372   removed in a future release.  Use the Preprocessor_Hash implementation
 373   instead.
 374 * Sanitizer::attributeWhitelist() and Sanitizer::setupAttributeWhitelist()
 375   have been deprecated; they will be made private in the future.
 376 * SearchResult::termMatches() method is deprecated. It was unreliable because
 377   only populated by few search engine implementations. Use
 378   SqlSearchResult::getTermMatches() if really needed.
 379 * SearchResult::getTextSnippet( $terms ) the $terms param is being deprecated
 380   and should no longer be passed. Search engine implemenations should be
 381   responsible for carrying relevant information needed for highlighting with
 382   their own SearchResultSet/SearchResult sub-classes.
 383 * SearchEngine::$searchTerms protected field is deprecated. Moved to
 384   SearchDatabase.
 385 * The use of the $terms param in the ShowSearchHit and ShowSearchHitTitle
 386   hooks is highly discouraged as it's only populated by SearchDatabase search
 387   engines.
 388 * Skin::escapeSearchLink() is deprecated. Use Skin::getSearchLink() or the skin
 389   template option 'searchaction' instead.
 390 * LoadBalancer::haveIndex() and LoadBalancer::isNonZeroLoad() have
 391   been deprecated.
 392 * User::getRights() and User::$mRights have been deprecated. Use

 400 == Compatibility ==
 401 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
 402 supported, it is generally advised to use PHP 7.0.13 or later for long term
 403 support.
 404
 405 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 406 but support for them is somewhat less mature. There is experimental support for
 407 Oracle and Microsoft SQL Server.
 408
 409 The supported versions are:
 410
 411 * MySQL 5.5.8 or later
 412 * PostgreSQL 9.2 or later
 413 * SQLite 3.8.0 or later
 414 * Oracle 9.0.1 or later
 415 * Microsoft SQL Server 2005 (9.00.1399)
