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 * $wgDBDefaultGroup – A default database group for use by maintenance scripts.
  31 * $wgResourceLoaderEnableJSProfiler – This new configuration setting lets you
  32   enable client-side profiling of JavaScript modules; it is off by default.
  33 * (T193868) $wgChangeTagsSchemaMigrationStage — This temporary configuration
  34   setting allows sysadmins to gradually migrate the database table schema for
  35   how change tags are stored.
  36 * (T199334) $wgTagStatisticsNewTable — This temporary configuration setting
  37   allows sysadmins to enable the caching of Special:Tags via the new
  38   change_tag_def table.
  39
  40 ==== Changed configuration ====
  41 * $wgUseAjax – This setting, deprecated in 1.31, is now ignored.
  42 * $wgDefaultUserOptions – The default watchlist view time (watchlistdays) has
  43   been increased from 3 to 7 days. (T194414)
  44 * $wgGroupPermissions – The right to edit sitewide Javascript
  45   (e.g. MediaWiki:Common.js), CSS or JSON was separated from 'editinterface'
  46   and is available under 'editsitejs'/'editsitecss'/'editsitejson'. Having
  47   'editinterface' is still necessary to edit such pages.
  48 * $wgMultiContentRevisionSchemaMigrationStage now defaults to writing both the
  49   old and the new schema, but reading the new schema, so Multi-Content Revisions
  50   (MCR) are now functional per default. The new default value of the setting is
  51   SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW.
  52 * $wgActorTableSchemaMigrationStage no longer accepts MIGRATION_WRITE_BOTH or
  53   MIGRATION_WRITE_NEW. It instead uses SCHEMA_COMPAT_WRITE_BOTH |
  54   SCHEMA_COMPAT_READ_OLD and SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW
  55   for intermediate stages of migration.
  56 * $wgDBTableOptions – The default table options now use the binary charset. The
  57   default was already overridden in the installer-generated LocalSettings.php,
  58   and so is always set to binary after the installer UI option was removed. The
  59   default value is only used when the installer installs an extension.
  60 * $wgPopularPasswordFile — The location of the default popular passwords file
  61   has been moved to be in line with other non-PHP files used by libraries and
  62   classes.
  63
  64 ==== Removed configuration ====
  65 * $wgEnableAPI and $wgEnableWriteAPI – These settings, deprecated in 1.31,
  66   have been removed. (T115414)
  67 * $wgSiteSupportPage – This setting, unused since 1.5, was removed.
  68 * $wgBrowserBlacklist – This setting, deprecated in 1.30, was removed.
  69 * $wgExperimentalHtmlIds – This setting, deprecated since 1.30, was removed.
  70   The 'html5-legacy' value for $wgFragmentMode is no longer accepted.
  71 * $wgPasswordSenderName - This setting, ignored since 1.23 by MediaWiki and
  72   most extensions, is no longer set. Instead, you can modify the system
  73   message `emailsender`.
  74 * $wgTidyConfig – The experimental Html5Internal and Html5Depurate tidy drivers
  75   were removed. RemexHtml, which is the default, should be used instead.
  76 * (T181318) The $wgStyleVersion setting and its appendage to various script and
  77   style URLs in OutputPage, deprecated in 1.31, was removed.
  78 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
  79   from ResourceLoader. Instead, use `@import` statements in LESS to import
  80   files directly from nearby directories within the same project.
  81 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
  82   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
  83   the ResourceLoaderModule::getLessVars() method.
  84 * $wgResourceLoaderValidateStaticJS – This setting, unused since MediaWiki 1.18,
  85   was removed.
  86 * Two temporary variables for deploying the feature of filters on change lists,
  87   $wgStructuredChangeFiltersShowPreference introduced in MediaWiki 1.30 and
  88   $wgStructuredChangeFiltersOnWatchlist in 1.31, were removed.
  89
  90 === New features in 1.32 ===
  91 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  92   using a particular page during edit previews.
  93 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  94   to true.
  95 * Added 'ApiParseMakeOutputPage' hook.
  96 * (T174313) Added checkbox on Special:ListUsers to display only users in
  97   temporary user groups.
  98 * (T152462) A cookie can now be set when an IP user is blocked to track that
  99   user if they move to a new IP address. This is disabled by default.
 100 * (T194950) Added 'ApiMaxLagInfo' hook.
 101 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
 102   reauthenticating.
 103 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
 104   getLoginSecurityLevel() returns non-false.
 105 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
 106   &$query and &$widthOption, allowing extensions even finer control over the
 107   resulting HTML code.
 108 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
 109   if the [mark as patrolled] link should be shown at the footer of patrollable
 110   pages.
 111 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
 112   is now passed by reference, allowing extensions to modify or even unset it.
 113 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
 114   modify the return value of OutputPage#getHeadLinksArray in order to add,
 115   remove or otherwise alter the elements to be output in the page <head>.
 116 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
 117   additional links to the subtitle of a history page.
 118 * The 'GetLinkColours' hook now receives an additional $title parameter,
 119   the Title object of the page being parsed, on which the links will be shown.
 120 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
 121   render diffs between two Content objects, and DifferenceEngine::setRevisions()
 122   to render diffs between two custom (potentially multi-content) revisions.
 123   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
 124 * Added a temporary action=mcrundo to the web UI, as the normal undo logic
 125   can't yet handle MCR and deadlines are forcing is to put off fixing that.
 126   This action should be considered deprecated and should not be used directly.
 127 * Extensions overriding ContentHandler::getUndoContent() will need to be
 128   updated for the changed method signature.
 129 * Added a new hook, 'UserGetRightsRemove', which can be used to remove rights
 130   from user. Unlike the 'UserGetRights' it will ensure that removed rights
 131   will not be reinserted.
 132

 169
 170 === Bug fixes in 1.32 ===
 171 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 172   getLoginSecurityLevel() returns non-false.
 173 * (T43720, T46197) Improved page display title handling for category pages
 174 * (T65080) Fixed resetting options of some types via API action=options.
 175
 176 === Action API changes in 1.32 ===
 177 * Added templated parameters.
 178   * A module can define a templated parameter like "{fruit}-quantity", where
 179     the actual parameters recognized correspond to the values of a multi-valued
 180     parameter. Then clients can make requests like
 181     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 182   * action=paraminfo will return templated parameter definitions separately
 183     from normal parameters. All parameter definitions now include an "index"
 184     key to allow clients to maintain parameter ordering when merging normal and
 185     templated parameters.
 186 * It is now an error to submit too many values for a multi-valued parameter.
 187   This has generated a warning since MediaWiki 1.14.
 188 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 189   longer use the action module's custom response format, for the few modules
 190   that use custom formatters that handle errors.
 191 * (T198935) User list preferences such as `email-blacklist` and similar
 192   extension preferences are no longer represented as arrays when returned by
 193   action=query&meta=userinfo&uiprop=options.
 194 * 'missingparam' errors will now use the prefixed parameter name in the code
 195   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 196   than "nofoo" and "The 'foo' parameter must be set".
 197 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 198   multi-content revision slots for which content should be returned. It also
 199   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 200   warning will be issued if rvprop=content or rvprop=contentmodel are used
 201   without rvslots.
 202 * The rvcontentformat parameter to action=query&prop=revisions has been
 203   deprecated. Clients should be prepared to deal with the default format for
 204   relevant models.
 205 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 206   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 207   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 208 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 209   action=query&list=alldeletedrevisions are changed similarly to
 210   &prop=revisions (see the three previous items).
 211 * (T174032) action=compare now supports multi-content revisions.
 212   * It has a 'slots' parameter to select diffing of individual slots. The
 213     default behavior is to return one combined diff.
 214   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 215     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 216     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 217     slots have text supplied and the corresponding templated parameters for
 218     each slot.
 219   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 220     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 221     instead expand the given text as if for a section edit. This effectively
 222     declines T183823 in favor of T185723.
 223 * (T198214) The 'disabletidy' parameter to action=parse has been
 224   deprecated; untidy output will not be supported by future wikitext
 225   parsers.
 226 * Added intestactionsdetail to action=query&prop=info to allow retrieving the
 227   reasons an action is not allowed.
 228 * Deprecated action=query&prop=info inprop=readable in favor of
 229   intestactions=read.
 230
 231 === Action API internal changes in 1.32 ===
 232 * Added 'ApiParseMakeOutputPage' hook.
 233 * Parameter names may no longer contain '{' or '}', as these are now used for
 234   templated parameters.
 235 * (T194950) Added 'ApiMaxLagInfo' hook.
 236 * The following methods now take a RevisionRecord rather than a Revision. No
 237   external callers are known.
 238   * ApiFeedContributions::feedItemAuthor()
 239   * ApiFeedContributions::feedItemDesc()
 240   * ApiQueryRevisionsBase::extractRevisionInfo()
 241 * The following deprecated methods have been removed:
 242   * ApiBase::profileIn() (deprecated in 1.25)
 243   * ApiBase::profileOut() (deprecated in 1.25)
 244   * ApiBase::safeProfileOut() (deprecated in 1.25)
 245   * ApiBase::profileDBIn() (deprecated in 1.25)
 246   * ApiBase::profileDBOut() (deprecated in 1.25)
 247   * ApiBase::dieUsage() (deprecated in 1.29)
 248   * ApiBase::dieUsageMsg() (deprecated in 1.29)
 249   * ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
 250   * ApiBase::getErrorFromStatus() (deprecated in 1.29)
 251   * ApiBase::parseMsg() (deprecated in 1.29)
 252   * ApiBase::setWarning() (deprecated in 1.29)
 253   * ApiPageSet::getInvalidTitles() (deprecated in 1.26)
 254   * ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
 255   * ApiUsageException::getCodeString() (deprecated in 1.29)
 256   * ApiUsageException::getMessageArray() (deprecated in 1.29)
 257 * Class UsageException, deprecated in 1.29, has been removed.
 258 * ApiErrorFormatter: Added getFormat() and newWithFormat(). In particular, you
 259   can now easily test $formatter->getFormat() === 'bc', and then call
 260   $formatter->newWithFormat( 'plaintext' ) to get a non-BC formatter.
 261
 262 === Languages updated in 1.32 ===
 263 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 264 Below only new and removed languages are listed, as well as changes to languages
 265 because of Phabricator reports.
 266
 267 * (T193566) Added language support for Ambonese Malay (abs).
 268 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 269 * (T195940) Added language support for Batak Mandailing (btm).
 270 * (T137491) Added language support for Standard Moroccan Amazigh (zgh).
 271 * (T198132) Added language support for Manipuri (mni).

 273 * (T201583) Added language support for Mon (mnw).
 274
 275 === Breaking changes in 1.32 ===
 276 * $wgRequestTime, deprecated in 1.25, was removed. Use
 277   $_SERVER['REQUEST_TIME_FLOAT'] or WebRequest::getElapsedTime() instead.
 278 * The MediaWikiI18N class, deprecated in 1.31, was removed.
 279 * QuickTemplate::setTranslator(), deprecated in 1.31, was removed. Use

 287 * EditPage::isOouiEnabled() deprecated in 1.30, was removed.
 288 * mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl()

 291   were deprecated in 1.25, have now been removed:
 292   * Revision::getRawUser()
 293   * Revision::getRawUserText()
 294   * Revision::getRawComment()
 295 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use
 296   mw.msg() or mw.message() instead.
 297 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 298   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 299 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
 300   jquery.accessKeyLabel instead.
 301 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 302 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 303   with the Balancer tidy implementation. Both implementations were experimental,
 304   and were replaced by RemexHtml.
 305 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 306   removed. Use JobQueueGroup::singleton()->push() instead.
 307 * The jquery.footHovzer module, for mediawiki.debug, was removed.
 308 * The es5-shim module, empty and deprecated since 1.29, was removed.
 309 * the dom-level2-shim module, empty and deprecated since 1.29, was removed.
 310 * the json module, empty and deprecated since 1.29, was removed.
 311 * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was
 312   removed. Use mediawiki.widgets.visibleLengthLimit instead.
 313 * The jquery.farbtastic module, unused since 1.18, was removed.
 314 * The 'jquery.expandableField' module, unused since 1.22, was removed.
 315 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 316   any HTMLForm object rather than PreferencesForm.
 317 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 318   Use Wikimedia\Timestamp\TimestampException instead.
 319 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 320   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 321   The UtfNormal\Utils class from the utfnormal library should be used instead.
 322 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 323   from the UtfNormal\Constants class from the utfnormal library should be used
 324 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 325   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 326   values `true` and `false` respectively.
 327 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 328   were removed. Use the ParserCache class instead.
 329 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 330   instead.
 331 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 332   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 333 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 334   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 335   is no longer loaded by default. The Vector and MonoBook skins have made a
 336   minor change to implement the toggle feature with CSS instead. To restore
 337   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 338   or refer to T195256 for details on how to make the same change.
 339 * Hook 'EditPageBeforeEditChecks' was removed;
 340   use 'EditPageGetCheckboxesDefinition' instead.
 341 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 342   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 343 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 344   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 345   instead.
 346 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 347   CapsuleMultiselectWidget. The following methods may no longer be used:
 348   * setItemsFromData: Use setValue instead
 349   * getItemsData: Use getItems instead and get the data property
 350 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 351   removed.  Use addLink() instead.
 352 * Another two OutputPage methods, setPageTitleActionText() and
 353   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 354   ten years).  Use setHTMLTitle() directly.
 355 * The return value of OutputPage::adaptCdnTTL() has been removed. The
 356   value returned was misleading and probably not what any caller would
 357   have wanted.
 358 * All MagicWord static member variables have been removed.  Use appropriate
 359   hooks or MagicWordFactory methods instead.
 360 * MagicWord::clearCache() has been removed.  Instead, create a new
 361   MagicWordFactory, such as by calling
 362   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 363 * mw.util.init() has been removed. This function is not needed anymore and was
 364   a no-op function since 1.30.
 365 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 366   instead.
 367 * MediaWiki no longer supports a StartProfiler.php file. Instead, you can set
 368   $wgProfiler and $wgEnableProfileInfo.
 369 * The mw.loader.addSource() is now considered a private method, and no longer
 370   supports the `id, url` signature. Use the `Object` parameter instead.
 371 * The backwards-compatibility code in HTMLForm to add a drop-down control to an
 372   option that is not set to be a drop-down if the "mw-chosen" class is present,
 373   is now removed.
 374 * Several collations were removed. They were workarounds for bugs in the ICU
 375   library and they are no longer needed (as of ICU 57.1):
 376   * 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
 377   * 'xx-uca-et' (CollationEt) - use 'uca-et' instead
 378   * 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
 379 * LanguageCode::bcp47() now always returns a valid BCP 47 code.  This means
 380   that some MediaWiki-specific language codes, such as `simple`, are mapped
 381   into valid BCP 47 codes (eg `en-simple`).
 382 * The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated
 383   in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'.
 384   The ChangesListSpecialPage code for these legacy hooks, and their use in
 385   SpecialRecentchanges.php and SpecialWatchlist, was also removed:
 386   * ChangesListSpecialPage->getCustomFilters()
 387   * ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters()
 388   * ChangesListSpecialPage::customFilters
 389 * The global function wfUseMW, deprecated since 1.26, has now been removed. Use
 390   the "requires" property of static extension registration instead.
 391 * $wgSpecialPages no longer accepts array syntax, deprecated since 1.18.
 392 * The MailAddress constructor can no longer be called with a User object,
 393   behaviour which has been deprecated since 1.24.
 394 * LBFactory, deprecated since 1.28, has been removed. Instead, use
 395   Wikimedia\Rdbms\LBFactory.
 396 * The MimeMagic class, deprecated since 1.28 has been removed. Get a
 397   MimeAnalyzer instance from MediaWikiServices instead.
 398 * The '--tidy' option to maintenance/parse.php has been removed.  Tidying
 399   the output is now the default.  Use '--no-tidy' to bypass the tidy
 400   phase.
 401 * The global function wfErrorLog, deprecated since 1.25, has now been removed.
 402   Use MWLoggerLegacyLogger::emit or UDPTransport.
 403 * The hooks 'SpecialRecentChangesQuery' & 'SpecialWatchlistQuery', deprecated in
 404   1.23, were removed. Instead, use ChangesListSpecialPageStructuredFilters or
 405   ChangesListSpecialPageQuery.
 406 * The global function wfUsePHP, deprecated since 1.30, has now been removed. To
 407   assert a newer version of PHP than MediaWiki does, use extension registration.
 408 * The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been
 409   removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
 410 * DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
 411 * File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
 412 * The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use
 413   the hook 'SkinEditSectionLinks' instead.
 414 * The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
 415 * The global function wfRunHooks, deprecated since 1.25, has now been removed.
 416   Use Hooks::run().
 417 * The hook 'UnknownAction', deprecated since 1.19, has now been removed.
 418 * The hook 'ParserLimitReport', deprecated since 1.22, has been removed. Use
 419   the hooks 'ParserLimitReportPrepare' and 'ParserLimitReportFormat' instead.
 420 * The following deprecated API methods have been removed:
 421   * ApiBase::profileIn() (deprecated in 1.25)
 422   * ApiBase::profileOut() (deprecated in 1.25)
 423   * ApiBase::safeProfileOut() (deprecated in 1.25)
 424   * ApiBase::profileDBIn() (deprecated in 1.25)
 425   * ApiBase::profileDBOut() (deprecated in 1.25)
 426   * ApiBase::dieUsage() (deprecated in 1.29)
 427   * ApiBase::dieUsageMsg() (deprecated in 1.29)
 428   * ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
 429   * ApiBase::getErrorFromStatus() (deprecated in 1.29)
 430   * ApiBase::parseMsg() (deprecated in 1.29)
 431   * ApiBase::setWarning() (deprecated in 1.29)
 432   * ApiPageSet::getInvalidTitles() (deprecated in 1.26)
 433   * ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
 434   * ApiUsageException::getCodeString() (deprecated in 1.29)
 435   * ApiUsageException::getMessageArray() (deprecated in 1.29)
 436 * Class UsageException, deprecated in 1.29, has been removed.
 437 * MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The
 438   old "bulletin board style toolbar", known as "the 2006 wikitext editor", has
 439   been removed, and instead sysadmins will be required to choose one (or more)
 440   of the several extensions available for this purpose if they need the
 441   functionality. The MediaWiki "tarball" releases have included the replacement
 442   extension for this, the WikiEditor extension aka "the 2010 wikitext editor",
 443   for many years now. As part of this, several parts of MediaWiki have been
 444   removed or simplified:
 445   * The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer
 446     available; if an extension adds a toolbar via the EditPageBeforeEditToolbar
 447     hook, it will be shown; extensions should provide a specific user preference
 448     to disable themselves as needed.
 449   * The public methods Language::getImageFile() and ::getImageFiles(), and the
 450     related specification of $imageFiles within individual languages' code file,
 451     as well as the referenced static media assets, all of which were only used
 452     inside MediaWiki itself for providing the icons for the old toolbar, have
 453     been removed without explicit deprecation.
 454   * The internal ResourceLoader module "mediawiki.toolbar", which is unused
 455     except by MediaWiki itself and back-compatibility code, has been removed.
 456   * The internal ResourceLoaderEditToolbarModule class has been removed.
 457
 458 === Deprecations in 1.32 ===
 459 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 460   button is already marked as progressive.
 461 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 462   has been centralised to Skin::getDefaultModules(), which is now capable
 463   of queueing style modules as well.
 464 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 465   deprecated. Use addModules() instead.
 466 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 467   in extending classes is deprecated.  Extend related doSearch* methods
 468   instead.
 469 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 470   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 471   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 472   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 473   mediawiki.api.messages, and mediawiki.api.rollback.
 474 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 475   to use it.
 476 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 477   with the 'unwatch' action parameter instead.
 478 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 479   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 480 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 481 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 482 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 483   of the namespaced classes provided by the wikimedia/xmp-reader library.
 484 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 485   use foreach on the SearchResultSet, or the extractResults method. Extending
 486   code should override extractResults.
 487 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 488   implementations must subclass SearchResultSet for their purposes.
 489 * SearchResult::setExtensionData argument has been changed from accepting an
 490   array to accepting a Closure that returns the array when called.
 491 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 492   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 493   generate cryptographically secure random byte sequences.
 494 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 495   instead.
 496 * Language::markNoConversion() is deprecated.  It confused readers because
 497   it had unexpected behavior (only marking text if it looked like a URL)
 498   and was only used in a single place in the code.  Use
 499   LanguageConverter::markNoConversion() instead.
 500 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 501   hard deprecated in this release.  It has been split into two similar
 502   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 503   which measure length in characters and bytes, respectively.  Use
 504   Language::truncateForVisual() when possible to provide equity to users
 505   of multibyte scripts.
 506 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 507   context title is unset is now deprecated; anything creating an EditPage
 508   instance should set the context title via ::setContextTitle().
 509 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 510 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 511   are deprecated. These concepts are obsolete and have no replacement.
 512 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 513 * The following methods of OutputPage are now deprecated in favour
 514   of using showFatalError directly: OutputPage::showFileDeleteError()
 515   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 516   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 517 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 518   classes are now deprecated. Use a Closure instead.
 519 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 520   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 521 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 522   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 523   the Parsoid v3 API in May 2015.
 524 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 525   $formDescriptor instead.
 526 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 527   to running searchText. This method was mainly implemented to support the
 528   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 529   logic as it should be handled internally by SearchEngine implementations
 530   supporting this feature. SearchEngine implementations should no longer
 531   override this methods.
 532 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 533   to running searchText/searchTitle.
 534 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 535   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 536 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 537   use array_filter() directly.
 538 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 539   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 540 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 541   Set $wgShowExceptionDetails instead.
 542 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 543   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 544   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 545   getOldRevision() / getNewRevision() for the first four (note that the
 546   revision ones return a RevisionRecord, not a Revision), do your own lookup
 547   for page/content.
 548 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 549   just enable the PHP extension, and it will be autodetected.
 550 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 551   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 552   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 553   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 554   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 555   to customize page-level diff properties (such as the navigation header).
 556 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 557 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 558   methods instead.
 559 * PasswordFactory::init is deprecated. To get a password factory with the
 560   standard configuration, use MediaWikiServices::getPasswordFactory.
 561 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 562   instead.
 563 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 564 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 565   instead.
 566 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 567 * All SpecialPageFactory static methods are deprecated. Instead, call the
 568   methods on a SpecialPageFactory instance, which may be obtained from
 569   MediaWikiServices.
 570 * mw.user.stickyRandomId was renamed to the more explicit
 571   mw.user.getPageviewToken to better capture its function.
 572 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 573   Content object should be passed instead.
 574 * (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
 575   previously used by OOUI HTMLForm fields, are now deprecated. Use
 576   'help', 'help-message', 'help-messages' instead.
 577 * (T197179) HTMLFormField::getNotices() is now deprecated.
 578 * The jquery.localize module is now deprecated. Use jquery.i18n instead.
 579 * The SecondaryDataUpdates hook was deprecated in favor of RevisionDataUpdates,
 580   or overriding ContentHandler::getSecondaryDataUpdates (T194038).
 581 * The WikiPageDeletionUpdates hook was deprecated in favor of
 582   PageDeletionDataUpdates, or overriding ContentHandler::getDeletionDataUpdates
 583   (T194038).
 584 * Content::getSecondaryDataUpdates has been deprecated in favor of
 585   ContentHandler::getSecondaryDataUpdates() for overriding by extensions
 586   (T194038).
 587   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 588 * Content::getDeletionUpdates has been deprecated in favor of
 589   ContentHandler::getDeletionUpdates() for overriding by extensions (T194038).
 590   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 591 * (T198214) Old Tidy-related configuration settings, which were soft-deprecated
 592   in MediaWiki 1.26, have now been hard deprecated. This affects $wgUseTidy,
 593   $wgTidyBin, $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy. Use
 594   $wgTidyConfig instead.
 595 * All Tidy configurations other than Remex have been hard deprecated;
 596   future parsers will not emit compatible output for these configurations.
 597 * (T198214) OutputPage::addWikiText(), OutputPage::addWikiTextWithTitle(),
 598   and OutputPage::addWikiTextTitle() have been deprecated, since they
 599   can result in untidy output.  In addition OutputPage::addWikiTextTidy()
 600   and OutputPage::addWikiTextTitleTidy() was deprecated to make naming new
 601   methods consistent.  Use OutputPage::addWikiTextAsInterface() or
 602   OutputPage::addWikiTextAsContent() instead, which ensures the output is
 603   tidy and clarifies whether content-language specific postprocessing should
 604   be done on the text.
 605 * QuickTemplate::msgHtml() and BaseTemplate::msgHtml() have been deprecated
 606   as they promote bad practises. I18n messages should always be properly
 607   escaped.
 608 * Skin::getDynamicStylesheetQuery() has been deprecated. It always
 609   returns action=raw&ctype=text/css which callers should use directly.
 610 * Class LegacyFormatter is deprecated.
 611 * Use of CommentStore::insertWithTempTable() with 'img_description' is
 612   deprecated. Use CommentStore::insert() instead.
 613 * Language::setCode is deprecated as public function. Use Language::factory
 614   to create a new Language object with a different language code.
 615 * Several classes have been moved from the MediaWiki\Storage\ namespace to the
 616   MediaWiki\Revision\ namespace. The old class names are aliased for
 617   compatibility, but are deprecated. Classes are IncompleteRevisionException,
 618   MutableRevisionRecord, MutableRevisionSlots, RevisionAccessException,
 619   RevisionArchiveRecord, RevisionFactory, RevisionLookup, RevisionRecord,
 620   RevisionSlots, RevisionStore, RevisionStoreRecord, SlotRecord, and
 621   SuppressedDataException.
 622 * When using OOUI HTMLForm containing an 'info' field which uses the 'rawrow'
 623   option, it is now deprecated to give its contents (the 'default' option)
 624   as a string. They should be given as a OOUI\FieldLayout object instead.
 625   Notably, this affects fields defined in the 'GetPreferences' hook, because
 626   Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
 627 * In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is
 628   deprecated. For the $lang parameter, types other than Language are
 629   deprecated.
 630 * The $wgUseKeyHeader configuration option and the
 631   OutputPage::getKeyHeader() method have been deprecated; the relevant
 632   draft IETF spec expired without becoming a standard.
 633 * Deprecated API action=query&prop=info inprop=readable in favor of
 634   intestactions=read.
 635
 636 === Other changes in 1.32 ===
 637 * (T198811) The following tables have had their UNIQUE indexes turned into
 638   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 639   protected_titles and site_identifiers.
 640 * OOUI HTMLForm will now display help text inline after the input field,
 641   rather than in a popup. Previous behavior can be restored by using
 642   `'help-inline' => false`.
 643 * The archive table's ar_rev_id field is now unique.
 644 * Special:BotPasswords now requires reauthentication.
 645 * (T174023) Multi-Content Revision (MCR) capabilities were introduced into the
 646   storage layer and have basic support for display. No user interface exists
 647   yet for creating or managing content in slots beides the main slot. See
 648   <https://www.mediawiki.org/wiki/Multi-Content_Revisions> for more
 649   information.
 650 * The image_comment_temp database table is merged into the image table and
 651   deprecated. Since access should be mediated by the CommentStore class, this
 652   change shouldn't affect external code.
 653 * (T206147) Database::close() will no longer commit any open transactions.
 654
 655 == Compatibility ==
 656 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 657 supported, it is generally advised to use PHP 7.0.0 or later for long term
 658 support.
 659
 660 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 661 but support for them is somewhat less mature. There is experimental support for
 662 Oracle and Microsoft SQL Server.
 663
 664 The supported versions are:
 665
 666 * MySQL 5.5.8 or later
 667 * PostgreSQL 9.2 or later
 668 * SQLite 3.3.7 or later
 669 * Oracle 9.0.1 or later
 670 * Microsoft SQL Server 2005 (9.00.1399)
 671
 672 == Upgrading ==
 673 1.32 has several database changes since 1.31, and will not work without schema
 674 updates. Note that due to changes to some very large tables like the revision
 675 table, the schema update may take quite long (minutes on a medium sized site,
 676 many hours on a large site).
 677
 678 Don't forget to always back up your database before upgrading!
 679
 680 See the file UPGRADE for more detailed upgrade instructions, including
 681 important information when upgrading from versions prior to 1.11.
