RELEASE-NOTES-1.32

   1 == MediaWiki 1.32 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.32 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.32 ===
   9 * (T115414) The $wgEnableAPI and $wgEnableWriteAPI settings, deprecated in 1.31,
  10   have been removed.
  11 * The $wgUseAjax setting, deprecated in 1.31, is now ignored.
  12 * The $wgSiteSupportPage setting, unused since 1.5, was removed.
  13 * The $wgBrowserBlacklist setting, deprecated in 1.30, was removed.
  14 * The default quality of JPEG thumbnails generated by GD was reduced from 95 to
  15   80. The quality of JPEG thumbnails is now configurable through the new setting
  16   $wgJpegQuality (default 80). This aligns the quality to what ImageMagick uses.
  17 * $wgExperimentalHtmlIds, deprecated since 1.30, has been removed. The
  18   'html5-legacy' value for $wgFragmentMode is no longer accepted.
  19 * The experimental Html5Internal and Html5Depurate tidy drivers were removed.
  20   RemexHtml, which is the default, should be used instead.
  21 * (T135963) You can now define a Content Security Policy for your wiki. This
  22   adds a defense-in-depth feature to stop an attacker who has found a bug in
  23   the parser allowing them to insert malicious attributes. Disabled by default,
  24   you can configure this via $wgCSPHeader and $wgCSPReportOnlyHeader.
  25 * New configuration variable has been added: $wgCookieSetOnIpBlock.
  26   This determines whether to set a cookie when an IP user is blocked. Doing so
  27   means that a blocked user, even after moving to a new IP address, will still
  28   be blocked.
  29 * The archive table's ar_rev_id field is now unique.
  30 * Special:BotPasswords now requires reauthentication.
  31 * (T194414) The default watchlist view time has been increased from 3 to 7 days.
  32 * The right to edit sitewide Javascript (e.g. MediaWiki:Common.js), CSS or JSON
  33   was separated from 'editinterface' and is available under
  34   'editsitejs'/'editsitecss'/'editsitejson'. Having 'editinterface' is still
  35   necessary to edit such pages.
  36 * A new user group, 'interface-admin', is added for controlling access to
  37   sitewide CSS/JS (and editing other users' CSS/JS). No other group has
  38   'editsitecss', 'editusercss', 'editsitejs' or 'edituserjs' by default.
  39 * A new grant group, 'editsiteconfig', is added for granting the above rights.
  40 * The $wgPasswordSenderName setting, ignored since 1.23 by MediaWiki and almost
  41   all extensions, is no longer set at all. Instead, you can modify the system
  42   message `emailsender`.
  43
  44 === New features in 1.32 ===
  45 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  46   using a particular page during edit previews.
  47 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  48   to true.
  49 * Added 'ApiParseMakeOutputPage' hook.
  50 * (T174313) Added checkbox on Special:ListUsers to display only users in
  51   temporary user groups.
  52 * (T152462) A cookie can now be set when an IP user is blocked to track that
  53   user if they move to a new IP address. This is disabled by default.
  54 * (T194950) Added 'ApiMaxLagInfo' hook.
  55 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  56   reauthenticating.
  57 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  58   getLoginSecurityLevel() returns non-false.
  59 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  60   &$query and &$widthOption, allowing extensions even finer control over the
  61   resulting HTML code.
  62 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
  63   if the [mark as patrolled] link should be shown at the footer of patrollable
  64   pages.
  65 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
  66   is now passed by reference, allowing extensions to modify or even unset it.
  67 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
  68   modify the return value of OutputPage#getHeadLinksArray in order to add,
  69   remove or otherwise alter the elements to be output in the page <head>.
  70 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
  71   additional links to the subtitle of a history page.
  72 * The 'GetLinkColours' hook now receives an additional $title parameter,
  73   the Title object of the page being parsed, on which the links will be shown.
  74 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
  75   render diffs between two Content objects, and DifferenceEngine::setRevisions()
  76   to render diffs between two custom (potentially multi-content) revisions.
  77   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
  78 * Added a temporary action=mcrundo to the web UI, as the normal undo logic
  79   can't yet handle MCR and deadlines are forcing is to put off fixing that.
  80   This action should be considered deprecated and should not be used directly.
  81 * Extensions overriding ContentHandler::getUndoContent() will need to be
  82   updated for the changed method signature.
  83

 104
 105 === Bug fixes in 1.32 ===
 106 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 107   getLoginSecurityLevel() returns non-false.
 108
 109 === Action API changes in 1.32 ===
 110 * Added templated parameters.
 111   * A module can define a templated parameter like "{fruit}-quantity", where
 112     the actual parameters recognized correspond to the values of a multi-valued
 113     parameter. Then clients can make requests like
 114     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 115   * action=paraminfo will return templated parameter definitions separately
 116     from normal parameters. All parameter definitions now include an "index"
 117     key to allow clients to maintain parameter ordering when merging normal and
 118     templated parameters.
 119 * It is now an error to submit too many values for a multi-valued parameter.
 120   This has generated a warning since MediaWiki 1.14.
 121 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 122   longer use the action module's custom response format, for the few modules
 123   that use custom formatters that handle errors.
 124 * (T198935) User list preferences such as `email-blacklist` and similar
 125   extension preferences are no longer represented as arrays when returned by
 126   action=query&meta=userinfo&uiprop=options.
 127 * 'missingparam' errors will now use the prefixed parameter name in the code
 128   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 129   than "nofoo" and "The 'foo' parameter must be set".
 130 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 131   multi-content revision slots for which content should be returned. It also
 132   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 133   warning will be issued if rvprop=content or rvprop=contentmodel are used
 134   without rvslots.
 135 * The rvcontentformat parameter to action=query&prop=revisions has been
 136   deprecated. Clients should be prepared to deal with the default format for
 137   relevant models.
 138 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 139   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 140   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 141 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 142   action=query&list=alldeletedrevisions are changed similarly to
 143   &prop=revisions (see the three previous items).
 144
 145 === Action API internal changes in 1.32 ===
 146 * Added 'ApiParseMakeOutputPage' hook.
 147 * Parameter names may no longer contain '{' or '}', as these are now used for
 148   templated parameters.
 149 * (T194950) Added 'ApiMaxLagInfo' hook.
 150 * Added 'ApiParseMakeOutputPage' hook.
 151 * The following methods now take a RevisionRecord rather than a Revision. No
 152   external callers are known.
 153   * ApiFeedContributions::feedItemAuthor()
 154   * ApiFeedContributions::feedItemDesc()
 155   * ApiQueryRevisionsBase::extractRevisionInfo()
 156
 157 === Languages updated in 1.32 ===
 158 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 159 Below only new and removed languages are listed, as well as changes to languages
 160 because of Phabricator reports.
 161

 196 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 197 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 198   with the Balancer tidy implementation. Both implementations were experimental,
 199   and were replaced by RemexHtml.
 200 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 201   removed. Use JobQueueGroup::singleton()->push() instead.
 202 * The jquery.footHovzer module, for mediawiki.debug, was removed.
 203 * The es5-shim module, empty and deprecated since 1.29, was removed.
 204 * the dom-level2-shim module, empty and deprecated since 1.29, was removed.

 208 * The jquery.farbtastic module, unused since 1.18, was removed.
 209 * The 'jquery.expandableField' module, unused since 1.22, was removed.
 210 * (T181318) The $wgStyleVersion setting and its appendage to various script and

 212 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 213   any HTMLForm object rather than PreferencesForm.
 214 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 215   Use Wikimedia\Timestamp\TimestampException instead.
 216 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 217   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 218   The UtfNormal\Utils class from the utfnormal library should be used instead.
 219 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 220   from the UtfNormal\Constants class from the utfnormal library should be used
 221 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 222   from ResourceLoader. Instead, use `@import` statements in LESS to import
 223   files directly from nearby directories within the same project.
 224 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
 225   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
 226   the ResourceLoaderModule::getLessVars() method.
 227 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 228   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 229   values `true` and `false` respectively.
 230 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 231   were removed. Use the ParserCache class instead.
 232 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 233   instead.
 234 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 235   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 236 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 237   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 238   is no longer loaded by default. The Vector and MonoBook skins have made a
 239   minor change to implement the toggle feature with CSS instead. To restore
 240   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 241   or refer to T195256 for details on how to make the same change.
 242 * Hook 'EditPageBeforeEditChecks' was removed;
 243   use 'EditPageGetCheckboxesDefinition' instead.
 244 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 245   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 246 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 247   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 248   instead.
 249 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 250   CapsuleMultiselectWidget. The following methods may no longer be used:
 251   * setItemsFromData: Use setValue instead
 252   * getItemsData: Use getItems instead and get the data property
 253 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 254   removed.  Use addLink() instead.
 255 * Another two OutputPage methods, setPageTitleActionText() and
 256   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 257   ten years).  Use setHTMLTitle() directly.
 258 * All MagicWord static member variables have been removed.  Use appropriate
 259   hooks or MagicWordFactory methods instead.
 260 * MagicWord::clearCache() has been removed.  Instead, create a new
 261   MagicWordFactory, such as by calling
 262   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 263 * mw.util.init() has been removed. This function is not needed anymore and was
 264   a no-op function since 1.30.
 265 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 266   instead.
 267
 268 === Deprecations in 1.32 ===
 269 * Use of a StartProfiler.php file is deprecated in favour of placing
 270   configuration in LocalSettings.php.
 271 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 272   button is already marked as progressive.
 273 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 274   has been centralised to Skin::getDefaultModules(), which is now capable
 275   of queueing style modules as well.
 276 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 277   deprecated. Use addModules() instead.
 278 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 279   in extending classes is deprecated.  Extend related doSearch* methods
 280   instead.
 281 * CollationFa has been removed completely as it's not needed anymore
 282 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 283   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 284   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 285   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 286   mediawiki.api.messages, and mediawiki.api.rollback.
 287 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 288   to use it.
 289 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 290   with the 'unwatch' action parameter instead.
 291 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 292   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 293 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 294 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 295 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 296   of the namespaced classes provided by the wikimedia/xmp-reader library.
 297 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 298   use foreach on the SearchResultSet, or the extractResults method. Extending
 299   code should override extractResults.
 300 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 301   implementations must subclass SearchResultSet for their purposes.
 302 * SearchResult::setExtensionData argument has been changed from accepting an
 303   array to accepting a Closure that returns the array when called.
 304 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 305   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 306   generate cryptographically secure random byte sequences.
 307 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 308   instead.
 309 * Language::markNoConversion() is deprecated.  It confused readers because
 310   it had unexpected behavior (only marking text if it looked like a URL)
 311   and was only used in a single place in the code.  Use
 312   LanguageConverter::markNoConversion() instead.
 313 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 314   hard deprecated in this release.  It has been split into two similar
 315   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 316   which measure length in characters and bytes, respectively.  Use
 317   Language::truncateForVisual() when possible to provide equity to users
 318   of multibyte scripts.
 319 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 320   context title is unset is now deprecated; anything creating an EditPage
 321   instance should set the context title via ::setContextTitle().
 322 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 323 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 324   are deprecated. These concepts are obsolete and have no replacement.
 325 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 326 * The following methods of OutputPage are now deprecated in favour
 327   of using showFatalError directly: OutputPage::showFileDeleteError()
 328   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 329   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 330 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 331   classes are now deprecated. Use a Closure instead.
 332 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 333   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 334 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 335   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 336   the Parsoid v3 API in May 2015.
 337 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 338   $formDescriptor instead.
 339 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 340   to running searchText. This method was mainly implemented to support the
 341   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 342   logic as it should be handled internally by SearchEngine implementations
 343   supporting this feature. SearchEngine implementations should no longer
 344   override this methods.
 345 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 346   to running searchText/searchTitle.
 347 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 348   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 349 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 350   use array_filter() directly.
 351 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 352   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 353 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 354   Set $wgShowExceptionDetails instead.
 355 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 356   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 357   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 358   getOldRevision() / getNewRevision() for the first four (note that the
 359   revision ones return a RevisionRecord, not a Revision), do your own lookup
 360   for page/content.
 361 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 362   just enable the PHP extension, and it will be autodetected.
 363 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 364   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 365   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 366   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 367   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 368   to customize page-level diff properties (such as the navigation header).
 369 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 370 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 371   methods instead.
 372 * PasswordFactory::init is deprecated. To get a password factory with the
 373   standard configuration, use MediaWikiServices::getPasswordFactory.
 374 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 375   instead.
 376 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 377 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 378   instead.
 379 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 380 * All SpecialPageFactory static methods are deprecated. Instead, call the
 381   methods on a SpecialPageFactory instance, which may be obtained from
 382   MediaWikiServices.
 383 * mw.user.stickyRandomId was renamed to the more explicit
 384   mw.user.getPageviewToken to better capture its function.
 385 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 386   Content object should be passed instead.

 388 === Other changes in 1.32 ===
 389 * (T198811) The following tables have had their UNIQUE indexes turned into
 390   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 391   protected_titles and site_identifiers.
 392 * OOUI HTMLForm will now display help text inline after the input field,
 393   rather than in a popup. Previous behavior can be restored by using
 394   `'help-inline' => false`.

 397 == Compatibility ==
 398 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 399 supported, it is generally advised to use PHP 7.0.0 or later for long term
 400 support.
 401
 402 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 403 but support for them is somewhat less mature. There is experimental support for
 404 Oracle and Microsoft SQL Server.
 405
 406 The supported versions are:
 407
 408 * MySQL 5.5.8 or later
 409 * PostgreSQL 9.2 or later
 410 * SQLite 3.3.7 or later
 411 * Oracle 9.0.1 or later
 412 * Microsoft SQL Server 2005 (9.00.1399)
 413
 414 == Upgrading ==
 415 1.32 has several database changes since 1.31, and will not work without schema
 416 updates. Note that due to changes to some very large tables like the revision
 417 table, the schema update may take quite long (minutes on a medium sized site,
 418 many hours on a large site).
 419
 420 Don't forget to always back up your database before upgrading!
 421
 422 See the file UPGRADE for more detailed upgrade instructions, including
 423 important information when upgrading from versions prior to 1.11.
