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
  10 ==== New configuration ====
  11 * $wgJpegQuality – The quality of JPEG thumbnails is now configurable through
  12   this setting. The default is 80, which matches the quality of JPEG thumbnails
  13   previously generated by ImageMagick. The quality of JPEG thumbnails generated
  14   by GD was previously 95, but now uses the $wgJpegQuality setting as well.
  15 * $wgCookieSetOnIpBlock - This determines whether to set a cookie when an IP
  16   user is blocked. Doing so means that a blocked user, even after moving to a
  17   new IP address, will still be blocked.
  18 * $wgRawHtmlMessages – This new configuration setting is added for listing
  19   messages which are displayed as raw HTML.
  20 * $wgCSPHeader and $wgCSPReportOnlyHeader – You can now define a
  21   "Content Security Policy" for your wiki. This adds a defense-in-depth feature
  22   to stop an attacker who has found a bug in the parser allowing them to insert
  23   malicious attributes. Disabled by default. (T135963)
  24 * $wgGroupPermissions – A new user group, 'interface-admin', is added for
  25   controlling access to sitewide CSS/JS (and editing other users' CSS/JS). No
  26   other group has 'editsitecss', 'editusercss', 'editsitejs' or 'edituserjs'
  27   by default.
  28 * $wgGrantPermissions – A new grant group, 'editsiteconfig', is added for
  29   granting the above rights.
  30
  31 ==== Changed configuration ====
  32 * $wgUseAjax – This setting, deprecated in 1.31, is now ignored.
  33 * $wgDefaultUserOptions – The default watchlist view time (watchlistdays) has
  34   been increased from 3 to 7 days. (T194414)
  35 * $wgGroupPermissions – The right to edit sitewide Javascript
  36   (e.g. MediaWiki:Common.js), CSS or JSON was separated from 'editinterface'
  37   and is available under 'editsitejs'/'editsitecss'/'editsitejson'. Having
  38   'editinterface' is still necessary to edit such pages.
  39 * $wgMultiContentRevisionSchemaMigrationStage now defaults to writing both the
  40   old and the new schema, but reading the new schema, so Multi-Content Revisions
  41   (MCR) are now functional per default. The new default value of the setting is
  42   SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW.
  43 * $wgActorTableSchemaMigrationStage no longer accepts MIGRATION_WRITE_BOTH or
  44   MIGRATION_WRITE_NEW. It instead uses SCHEMA_COMPAT_WRITE_BOTH |
  45   SCHEMA_COMPAT_READ_OLD and SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW
  46   for intermediate stages of migration.
  47
  48 ==== Removed configuration ====
  49 * $wgEnableAPI and $wgEnableWriteAPI – These settings, deprecated in 1.31,
  50   have been removed. (T115414)
  51 * $wgSiteSupportPage – This setting, unused since 1.5, was removed.
  52 * $wgBrowserBlacklist – This setting, deprecated in 1.30, was removed.
  53 * $wgExperimentalHtmlIds – This setting, deprecated since 1.30, was removed.
  54   The 'html5-legacy' value for $wgFragmentMode is no longer accepted.
  55 * $wgPasswordSenderName - This setting, ignored since 1.23 by MediaWiki and
  56   most extensions, is no longer set. Instead, you can modify the system
  57   message `emailsender`.
  58 * $wgTidyConfig – The experimental Html5Internal and Html5Depurate tidy drivers
  59   were removed. RemexHtml, which is the default, should be used instead.
  60
  61 === New features in 1.32 ===
  62 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  63   using a particular page during edit previews.
  64 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  65   to true.
  66 * Added 'ApiParseMakeOutputPage' hook.
  67 * (T174313) Added checkbox on Special:ListUsers to display only users in
  68   temporary user groups.
  69 * (T152462) A cookie can now be set when an IP user is blocked to track that
  70   user if they move to a new IP address. This is disabled by default.
  71 * (T194950) Added 'ApiMaxLagInfo' hook.
  72 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  73   reauthenticating.
  74 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  75   getLoginSecurityLevel() returns non-false.
  76 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  77   &$query and &$widthOption, allowing extensions even finer control over the
  78   resulting HTML code.
  79 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
  80   if the [mark as patrolled] link should be shown at the footer of patrollable
  81   pages.
  82 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
  83   is now passed by reference, allowing extensions to modify or even unset it.
  84 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
  85   modify the return value of OutputPage#getHeadLinksArray in order to add,
  86   remove or otherwise alter the elements to be output in the page <head>.
  87 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
  88   additional links to the subtitle of a history page.
  89 * The 'GetLinkColours' hook now receives an additional $title parameter,
  90   the Title object of the page being parsed, on which the links will be shown.
  91 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
  92   render diffs between two Content objects, and DifferenceEngine::setRevisions()
  93   to render diffs between two custom (potentially multi-content) revisions.
  94   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
  95 * Added a temporary action=mcrundo to the web UI, as the normal undo logic
  96   can't yet handle MCR and deadlines are forcing is to put off fixing that.
  97   This action should be considered deprecated and should not be used directly.
  98 * Extensions overriding ContentHandler::getUndoContent() will need to be
  99   updated for the changed method signature.
 100 * Added a new hook, 'UserGetRightsRemove', which can be used to remove rights
 101   from user. Unlike the 'UserGetRights' it will ensure that removed rights
 102   will not be reinserted.
 103
 104 === External library changes in 1.32 ===
 105
 106 ==== New external libraries ====
 107 * Added wikimedia/xmp-reader 0.6.0.

 109 * …
 110

 113 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
 114 ** ScopedCallback objects can no longer be serialized.
 115 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
 116 * Updated mediawiki/mediawiki-codesniffer from v20.0.0 to v21.0.0.
 117 * Updated composer/spdx-licenses from 1.3.0 to 1.4.0.

 122
 123 ==== Removed external libraries ====
 124 * pear/mail_mime-decode was removed.
 125 * …
 126
 127 === Bug fixes in 1.32 ===
 128 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 129   getLoginSecurityLevel() returns non-false.
 130 * (T43720, T46197) Improved page display title handling for category pages
 131 * (T65080) Fixed resetting options of some types via API action=options.
 132
 133 === Action API changes in 1.32 ===
 134 * Added templated parameters.
 135   * A module can define a templated parameter like "{fruit}-quantity", where
 136     the actual parameters recognized correspond to the values of a multi-valued
 137     parameter. Then clients can make requests like
 138     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 139   * action=paraminfo will return templated parameter definitions separately
 140     from normal parameters. All parameter definitions now include an "index"
 141     key to allow clients to maintain parameter ordering when merging normal and
 142     templated parameters.
 143 * It is now an error to submit too many values for a multi-valued parameter.
 144   This has generated a warning since MediaWiki 1.14.
 145 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 146   longer use the action module's custom response format, for the few modules
 147   that use custom formatters that handle errors.
 148 * (T198935) User list preferences such as `email-blacklist` and similar
 149   extension preferences are no longer represented as arrays when returned by
 150   action=query&meta=userinfo&uiprop=options.
 151 * 'missingparam' errors will now use the prefixed parameter name in the code
 152   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 153   than "nofoo" and "The 'foo' parameter must be set".
 154 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 155   multi-content revision slots for which content should be returned. It also
 156   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 157   warning will be issued if rvprop=content or rvprop=contentmodel are used
 158   without rvslots.
 159 * The rvcontentformat parameter to action=query&prop=revisions has been
 160   deprecated. Clients should be prepared to deal with the default format for
 161   relevant models.
 162 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 163   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 164   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 165 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 166   action=query&list=alldeletedrevisions are changed similarly to
 167   &prop=revisions (see the three previous items).
 168 * (T174032) action=compare now supports multi-content revisions.
 169   * It has a 'slots' parameter to select diffing of individual slots. The
 170     default behavior is to return one combined diff.
 171   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 172     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 173     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 174     slots have text supplied and the corresponding templated parameters for
 175     each slot.
 176   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 177     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 178     instead expand the given text as if for a section edit. This effectively
 179     declines T183823 in favor of T185723.
 180 * (T198214) The 'disabletidy' parameter to action=parse has been
 181   deprecated; untidy output will not be supported by future wikitext
 182   parsers.
 183
 184 === Action API internal changes in 1.32 ===
 185 * Added 'ApiParseMakeOutputPage' hook.
 186 * Parameter names may no longer contain '{' or '}', as these are now used for
 187   templated parameters.
 188 * (T194950) Added 'ApiMaxLagInfo' hook.
 189 * The following methods now take a RevisionRecord rather than a Revision. No
 190   external callers are known.
 191   * ApiFeedContributions::feedItemAuthor()
 192   * ApiFeedContributions::feedItemDesc()
 193   * ApiQueryRevisionsBase::extractRevisionInfo()
 194 * The following deprecated methods have been removed:
 195   * ApiBase::profileIn() (deprecated in 1.25)
 196   * ApiBase::profileOut() (deprecated in 1.25)
 197   * ApiBase::safeProfileOut() (deprecated in 1.25)
 198   * ApiBase::profileDBIn() (deprecated in 1.25)
 199   * ApiBase::profileDBOut() (deprecated in 1.25)
 200   * ApiBase::dieUsage() (deprecated in 1.29)
 201   * ApiBase::dieUsageMsg() (deprecated in 1.29)
 202   * ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
 203   * ApiBase::getErrorFromStatus() (deprecated in 1.29)
 204   * ApiBase::parseMsg() (deprecated in 1.29)
 205   * ApiBase::setWarning() (deprecated in 1.29)
 206   * ApiPageSet::getInvalidTitles() (deprecated in 1.26)
 207   * ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
 208   * ApiUsageException::getCodeString() (deprecated in 1.29)
 209   * ApiUsageException::getMessageArray() (deprecated in 1.29)
 210 * Class UsageException, deprecated in 1.29, has been removed.
 211
 212 === Languages updated in 1.32 ===

 214 Below only new and removed languages are listed, as well as changes to languages
 215 because of Phabricator reports.

 224
 225 === Breaking changes in 1.32 ===

 227   $_SERVER['REQUEST_TIME_FLOAT'] or WebRequest::getElapsedTime() instead.
 228 * The MediaWikiI18N class, deprecated in 1.31, was removed.
 229 * QuickTemplate::setTranslator(), deprecated in 1.31, was removed. Use
 230   Skin::msg() instead.

 236   MediaWiki\Session\Token::SUFFIX instead.
 237 * EditPage::isOouiEnabled() deprecated in 1.30, was removed.
 238 * mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl()

 241   were deprecated in 1.25, have now been removed:
 242   * Revision::getRawUser()
 243   * Revision::getRawUserText()
 244   * Revision::getRawComment()
 245 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use
 246   mw.msg() or mw.message() instead.
 247 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 248   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 249 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
 250   jquery.accessKeyLabel instead.
 251 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 252 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 253   with the Balancer tidy implementation. Both implementations were experimental,
 254   and were replaced by RemexHtml.
 255 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 256   removed. Use JobQueueGroup::singleton()->push() instead.
 257 * The jquery.footHovzer module, for mediawiki.debug, was removed.

 260 * the json module, empty and deprecated since 1.29, was removed.
 261 * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was
 262   removed. Use mediawiki.widgets.visibleLengthLimit instead.
 263 * The jquery.farbtastic module, unused since 1.18, was removed.
 264 * The 'jquery.expandableField' module, unused since 1.22, was removed.
 265 * (T181318) The $wgStyleVersion setting and its appendage to various script and
 266   style URLs in OutputPage, deprecated in 1.31, was removed.
 267 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 268   any HTMLForm object rather than PreferencesForm.
 269 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 270   Use Wikimedia\Timestamp\TimestampException instead.
 271 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 272   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 273   The UtfNormal\Utils class from the utfnormal library should be used instead.
 274 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 275   from the UtfNormal\Constants class from the utfnormal library should be used
 276 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 277   from ResourceLoader. Instead, use `@import` statements in LESS to import
 278   files directly from nearby directories within the same project.
 279 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
 280   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
 281   the ResourceLoaderModule::getLessVars() method.
 282 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 283   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 284   values `true` and `false` respectively.
 285 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 286   were removed. Use the ParserCache class instead.
 287 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 288   instead.
 289 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 290   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 291 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 292   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 293   is no longer loaded by default. The Vector and MonoBook skins have made a
 294   minor change to implement the toggle feature with CSS instead. To restore
 295   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 296   or refer to T195256 for details on how to make the same change.
 297 * Hook 'EditPageBeforeEditChecks' was removed;
 298   use 'EditPageGetCheckboxesDefinition' instead.
 299 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 300   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 301 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 302   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 303   instead.
 304 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 305   CapsuleMultiselectWidget. The following methods may no longer be used:
 306   * setItemsFromData: Use setValue instead
 307   * getItemsData: Use getItems instead and get the data property
 308 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 309   removed.  Use addLink() instead.
 310 * Another two OutputPage methods, setPageTitleActionText() and
 311   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 312   ten years).  Use setHTMLTitle() directly.
 313 * The return value of OutputPage::adaptCdnTTL() has been removed. The
 314   value returned was misleading and probably not what any caller would
 315   have wanted.
 316 * All MagicWord static member variables have been removed.  Use appropriate
 317   hooks or MagicWordFactory methods instead.
 318 * MagicWord::clearCache() has been removed.  Instead, create a new
 319   MagicWordFactory, such as by calling
 320   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 321 * mw.util.init() has been removed. This function is not needed anymore and was
 322   a no-op function since 1.30.
 323 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 324   instead.
 325 * MediaWiki no longer supports a StartProfiler.php file.
 326   Define $wgProfiler via LocalSettings.php instead.
 327 * The mw.loader.addSource() is now considered a private method, and no longer
 328   supports the `id, url` signature. Use the `Object` parameter instead.
 329 * The backwards-compatibility code in HTMLForm to add a drop-down control to an
 330   option that is not set to be a drop-down if the "mw-chosen" class is present,
 331   is now removed.
 332 * Several collations were removed. They were workarounds for bugs in the ICU
 333   library and they are no longer needed (as of ICU 57.1):
 334   * 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
 335   * 'xx-uca-et' (CollationEt) - use 'uca-et' instead
 336   * 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
 337 * LanguageCode::bcp47() now always returns a valid BCP 47 code.  This means
 338   that some MediaWiki-specific language codes, such as `simple`, are mapped
 339   into valid BCP 47 codes (eg `en-simple`).
 340 * The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated
 341   in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'.
 342   The ChangesListSpecialPage code for these legacy hooks, and their use in
 343   SpecialRecentchanges.php and SpecialWatchlist, was also removed:
 344   * ChangesListSpecialPage->getCustomFilters()
 345   * ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters()
 346   * ChangesListSpecialPage::customFilters
 347 * The global function wfUseMW, deprecated since 1.26, has now been removed. Use
 348   the "requires" property of static extension registration instead.
 349 * $wgSpecialPages no longer accepts array syntax, deprecated since 1.18.
 350 * The MailAddress constructor can no longer be called with a User object,
 351   behaviour which has been deprecated since 1.24.
 352 * LBFactory, deprecated since 1.28, has been removed. Instead, use
 353   Wikimedia\Rdbms\LBFactory.
 354 * The MimeMagic class, deprecated since 1.28 has been removed. Get a
 355   MimeAnalyzer instance from MediaWikiServices instead.
 356 * The '--tidy' option to maintenance/parse.php has been removed.  Tidying
 357   the output is now the default.  Use '--no-tidy' to bypass the tidy
 358   phase.
 359 * The global function wfErrorLog, deprecated since 1.25, has now been removed.
 360   Use MWLoggerLegacyLogger::emit or UDPTransport.
 361 * The hooks 'SpecialRecentChangesQuery' & 'SpecialWatchlistQuery', deprecated in
 362   1.23, were removed. Instead, use ChangesListSpecialPageStructuredFilters or
 363   ChangesListSpecialPageQuery.
 364 * The global function wfUsePHP, deprecated since 1.30, has now been removed. To
 365   assert a newer version of PHP than MediaWiki does, use extension registration.
 366 * The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been
 367   removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
 368 * DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
 369 * File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
 370 * The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use
 371   the hook 'SkinEditSectionLinks' instead.
 372 * The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
 373 * The global function wfRunHooks, deprecated since 1.25, has now been removed.
 374   Use Hooks::run().
 375 * The hook 'UnknownAction', deprecated since 1.19, has now been removed.
 376 * The hook 'ParserLimitReport', deprecated since 1.22, has been removed. Use
 377   the hooks 'ParserLimitReportPrepare' and 'ParserLimitReportFormat' instead.
 378 * The following deprecated API methods have been removed:
 379   * ApiBase::profileIn() (deprecated in 1.25)
 380   * ApiBase::profileOut() (deprecated in 1.25)
 381   * ApiBase::safeProfileOut() (deprecated in 1.25)
 382   * ApiBase::profileDBIn() (deprecated in 1.25)
 383   * ApiBase::profileDBOut() (deprecated in 1.25)
 384   * ApiBase::dieUsage() (deprecated in 1.29)
 385   * ApiBase::dieUsageMsg() (deprecated in 1.29)
 386   * ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
 387   * ApiBase::getErrorFromStatus() (deprecated in 1.29)
 388   * ApiBase::parseMsg() (deprecated in 1.29)
 389   * ApiBase::setWarning() (deprecated in 1.29)
 390   * ApiPageSet::getInvalidTitles() (deprecated in 1.26)
 391   * ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
 392   * ApiUsageException::getCodeString() (deprecated in 1.29)
 393   * ApiUsageException::getMessageArray() (deprecated in 1.29)
 394 * Class UsageException, deprecated in 1.29, has been removed.
 395 * MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The
 396   old "bulletin board style toolbar", known as "the 2006 wikitext editor", has
 397   been removed, and instead sysadmins will be required to choose one (or more)
 398   of the several extensions available for this purpose if they need the
 399   functionality. The MediaWiki "tarball" releases have included the replacement
 400   extension for this, the WikiEditor extension aka "the 2010 wikitext editor",
 401   for many years now. As part of this, several parts of MediaWiki have been
 402   removed or simplified:
 403   * The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer
 404     available; if an extension adds a toolbar via the EditPageBeforeEditToolbar
 405     hook, it will be shown; extensions should provide a specific user preference
 406     to disable themselves as needed.
 407   * The public methods Language::getImageFile() and ::getImageFiles(), and the
 408     related specification of $imageFiles within individual languages' code file,
 409     as well as the referenced static media assets, all of which were only used
 410     inside MediaWiki itself for providing the icons for the old toolbar, have
 411     been removed without explicit deprecation.
 412   * The internal ResourceLoader module "mediawiki.toolbar", which is unused
 413     except by MediaWiki itself and back-compatibility code, has been removed.
 414   * The internal ResourceLoaderEditToolbarModule class has been removed.
 415
 416 === Deprecations in 1.32 ===
 417 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 418   button is already marked as progressive.
 419 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 420   has been centralised to Skin::getDefaultModules(), which is now capable
 421   of queueing style modules as well.
 422 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 423   deprecated. Use addModules() instead.
 424 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 425   in extending classes is deprecated.  Extend related doSearch* methods
 426   instead.
 427 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 428   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 429   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 430   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 431   mediawiki.api.messages, and mediawiki.api.rollback.
 432 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 433   to use it.
 434 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 435   with the 'unwatch' action parameter instead.
 436 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 437   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 438 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 439 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 440 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 441   of the namespaced classes provided by the wikimedia/xmp-reader library.
 442 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 443   use foreach on the SearchResultSet, or the extractResults method. Extending
 444   code should override extractResults.
 445 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 446   implementations must subclass SearchResultSet for their purposes.
 447 * SearchResult::setExtensionData argument has been changed from accepting an
 448   array to accepting a Closure that returns the array when called.
 449 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 450   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 451   generate cryptographically secure random byte sequences.
 452 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 453   instead.
 454 * Language::markNoConversion() is deprecated.  It confused readers because
 455   it had unexpected behavior (only marking text if it looked like a URL)
 456   and was only used in a single place in the code.  Use
 457   LanguageConverter::markNoConversion() instead.
 458 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 459   hard deprecated in this release.  It has been split into two similar
 460   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 461   which measure length in characters and bytes, respectively.  Use
 462   Language::truncateForVisual() when possible to provide equity to users
 463   of multibyte scripts.
 464 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 465   context title is unset is now deprecated; anything creating an EditPage
 466   instance should set the context title via ::setContextTitle().
 467 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 468 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 469   are deprecated. These concepts are obsolete and have no replacement.
 470 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 471 * The following methods of OutputPage are now deprecated in favour
 472   of using showFatalError directly: OutputPage::showFileDeleteError()
 473   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 474   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 475 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 476   classes are now deprecated. Use a Closure instead.
 477 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 478   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 479 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 480   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 481   the Parsoid v3 API in May 2015.
 482 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 483   $formDescriptor instead.
 484 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 485   to running searchText. This method was mainly implemented to support the
 486   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 487   logic as it should be handled internally by SearchEngine implementations
 488   supporting this feature. SearchEngine implementations should no longer
 489   override this methods.
 490 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 491   to running searchText/searchTitle.
 492 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 493   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 494 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 495   use array_filter() directly.
 496 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 497   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 498 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 499   Set $wgShowExceptionDetails instead.
 500 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 501   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 502   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 503   getOldRevision() / getNewRevision() for the first four (note that the
 504   revision ones return a RevisionRecord, not a Revision), do your own lookup
 505   for page/content.
 506 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 507   just enable the PHP extension, and it will be autodetected.
 508 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 509   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 510   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 511   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 512   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 513   to customize page-level diff properties (such as the navigation header).
 514 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 515 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 516   methods instead.
 517 * PasswordFactory::init is deprecated. To get a password factory with the
 518   standard configuration, use MediaWikiServices::getPasswordFactory.
 519 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 520   instead.
 521 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 522 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 523   instead.
 524 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 525 * All SpecialPageFactory static methods are deprecated. Instead, call the
 526   methods on a SpecialPageFactory instance, which may be obtained from
 527   MediaWikiServices.
 528 * mw.user.stickyRandomId was renamed to the more explicit
 529   mw.user.getPageviewToken to better capture its function.
 530 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 531   Content object should be passed instead.
 532 * (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
 533   previously used by OOUI HTMLForm fields, are now deprecated. Use
 534   'help', 'help-message', 'help-messages' instead.
 535 * (T197179) HTMLFormField::getNotices() is now deprecated.
 536 * The jquery.localize module is now deprecated. Use jquery.i18n instead.
 537 * The SecondaryDataUpdates hook was deprecated in favor of RevisionDataUpdates,
 538   or overriding ContentHandler::getSecondaryDataUpdates (T194038).
 539 * The WikiPageDeletionUpdates hook was deprecated in favor of
 540   PageDeletionDataUpdates, or overriding ContentHandler::getDeletionDataUpdates
 541   (T194038).
 542 * Content::getSecondaryDataUpdates has been deprecated in favor of
 543   ContentHandler::getSecondaryDataUpdates() for overriding by extensions
 544   (T194038).
 545   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 546 * Content::getDeletionUpdates has been deprecated in favor of
 547   ContentHandler::getDeletionUpdates() for overriding by extensions (T194038).
 548   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 549 * (T198214) Old Tidy-related configuration settings, which were soft-deprecated
 550   in MediaWiki 1.26, have now been hard deprecated. This affects $wgUseTidy,
 551   $wgTidyBin, $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy. Use
 552   $wgTidyConfig instead.
 553 * All Tidy configurations other than Remex have been hard deprecated;
 554   future parsers will not emit compatible output for these configurations.
 555 * (T198214) OutputPage::addWikiText(), OutputPage::addWikiTextWithTitle(),
 556   and OutputPage::addWikiTextTitle() have been deprecated, since they
 557   can result in untidy output.  In addition OutputPage::addWikiTextTidy()
 558   and OutputPage::addWikiTextTitleTidy() was deprecated to make naming new
 559   methods consistent.  Use OutputPage::addWikiTextAsInterface() or
 560   OutputPage::addWikiTextAsContent() instead, which ensures the output is
 561   tidy and clarifies whether content-language specific postprocessing should
 562   be done on the text.
 563 * QuickTemplate::msgHtml() and BaseTemplate::msgHtml() have been deprecated
 564   as they promote bad practises. I18n messages should always be properly
 565   escaped.
 566 * Skin::getDynamicStylesheetQuery() has been deprecated. It always
 567   returns action=raw&ctype=text/css which callers should use directly.
 568 * Class LegacyFormatter is deprecated.
 569 * Use of CommentStore::insertWithTempTable() with 'img_description' is
 570   deprecated. Use CommentStore::insert() instead.
 571 * Language::setCode is deprecated as public function. Use Language::factory
 572   to create a new Language object with a different language code.
 573 * Several classes have been moved from the MediaWiki\Storage\ namespace to the
 574   MediaWiki\Revision\ namespace. The old class names are aliased for
 575   compatibility, but are deprecated. Classes are IncompleteRevisionException,
 576   MutableRevisionRecord, MutableRevisionSlots, RevisionAccessException,
 577   RevisionArchiveRecord, RevisionFactory, RevisionLookup, RevisionRecord,
 578   RevisionSlots, RevisionStore, RevisionStoreRecord, SlotRecord, and
 579   SuppressedDataException.
 580 * When using OOUI HTMLForm containing an 'info' field which uses the 'rawrow'
 581   option, it is now deprecated to give its contents (the 'default' option)
 582   as a string. They should be given as a OOUI\FieldLayout object instead.
 583   Notably, this affects fields defined in the 'GetPreferences' hook, because
 584   Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
 585 * In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is
 586   deprecated. For the $lang parameter, types other than Language are
 587   deprecated.
 588 * The $wgUseKeyHeader configuration option and the
 589   OutputPage::getKeyHeader() method have been deprecated; the relevant
 590   draft IETF spec expired without becoming a standard.
 591
 592 === Other changes in 1.32 ===
 593 * (T198811) The following tables have had their UNIQUE indexes turned into
 594   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 595   protected_titles and site_identifiers.
 596 * OOUI HTMLForm will now display help text inline after the input field,
 597   rather than in a popup. Previous behavior can be restored by using
 598   `'help-inline' => false`.
 599 * The archive table's ar_rev_id field is now unique.
 600 * Special:BotPasswords now requires reauthentication.
 601 * (T174023) Multi-Content Revision (MCR) capabilities were introduced into the
 602   storage layer and have basic support for display. No user interface exists
 603   yet for creating or managing content in slots beides the main slot. See
 604   <https://www.mediawiki.org/wiki/Multi-Content_Revisions> for more
 605   information.
 606 * The image_comment_temp database table is merged into the image table and
 607   deprecated. Since access should be mediated by the CommentStore class, this
 608   change shouldn't affect external code.
 609 * (T206147) Database::close() will no longer commit any open transactions.
 610
 611 == Compatibility ==
 612 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 613 supported, it is generally advised to use PHP 7.0.0 or later for long term
 614 support.
 615
 616 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 617 but support for them is somewhat less mature. There is experimental support for
 618 Oracle and Microsoft SQL Server.
 619
 620 The supported versions are:
 621
 622 * MySQL 5.5.8 or later
 623 * PostgreSQL 9.2 or later
 624 * SQLite 3.3.7 or later
 625 * Oracle 9.0.1 or later
 626 * Microsoft SQL Server 2005 (9.00.1399)
 627
 628 == Upgrading ==
 629 1.32 has several database changes since 1.31, and will not work without schema
 630 updates. Note that due to changes to some very large tables like the revision
 631 table, the schema update may take quite long (minutes on a medium sized site,
 632 many hours on a large site).
 633
 634 Don't forget to always back up your database before upgrading!
 635
 636 See the file UPGRADE for more detailed upgrade instructions, including
 637 important information when upgrading from versions prior to 1.11.
