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
 133 === External library changes in 1.32 ===
 134
 135 ==== New external libraries ====
 136 * Added wikimedia/xmp-reader 0.6.0.

 138 * …
 139
 140 ==== Changed external libraries ====
 141 * Updated qunitjs from 2.4.0 to 2.6.2.
 142 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
 143 ** ScopedCallback objects can no longer be serialized.
 144 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
 145 * Updated mediawiki/mediawiki-codesniffer from v20.0.0 to v21.0.0.
 146 * Updated composer/spdx-licenses from 1.3.0 to 1.4.0.

 151
 152 ==== Removed external libraries ====
 153 * pear/mail_mime-decode was removed.
 154 * …
 155
 156 === Bug fixes in 1.32 ===
 157 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 158   getLoginSecurityLevel() returns non-false.
 159 * (T43720, T46197) Improved page display title handling for category pages
 160 * (T65080) Fixed resetting options of some types via API action=options.
 161
 162 === Action API changes in 1.32 ===
 163 * Added templated parameters.
 164   * A module can define a templated parameter like "{fruit}-quantity", where
 165     the actual parameters recognized correspond to the values of a multi-valued
 166     parameter. Then clients can make requests like
 167     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 168   * action=paraminfo will return templated parameter definitions separately
 169     from normal parameters. All parameter definitions now include an "index"
 170     key to allow clients to maintain parameter ordering when merging normal and
 171     templated parameters.
 172 * It is now an error to submit too many values for a multi-valued parameter.
 173   This has generated a warning since MediaWiki 1.14.
 174 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 175   longer use the action module's custom response format, for the few modules
 176   that use custom formatters that handle errors.
 177 * (T198935) User list preferences such as `email-blacklist` and similar
 178   extension preferences are no longer represented as arrays when returned by
 179   action=query&meta=userinfo&uiprop=options.
 180 * 'missingparam' errors will now use the prefixed parameter name in the code
 181   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 182   than "nofoo" and "The 'foo' parameter must be set".
 183 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 184   multi-content revision slots for which content should be returned. It also
 185   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 186   warning will be issued if rvprop=content or rvprop=contentmodel are used
 187   without rvslots.
 188 * The rvcontentformat parameter to action=query&prop=revisions has been
 189   deprecated. Clients should be prepared to deal with the default format for
 190   relevant models.
 191 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 192   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 193   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 194 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 195   action=query&list=alldeletedrevisions are changed similarly to
 196   &prop=revisions (see the three previous items).
 197 * (T174032) action=compare now supports multi-content revisions.
 198   * It has a 'slots' parameter to select diffing of individual slots. The
 199     default behavior is to return one combined diff.
 200   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 201     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 202     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 203     slots have text supplied and the corresponding templated parameters for
 204     each slot.
 205   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 206     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 207     instead expand the given text as if for a section edit. This effectively
 208     declines T183823 in favor of T185723.
 209 * (T198214) The 'disabletidy' parameter to action=parse has been
 210   deprecated; untidy output will not be supported by future wikitext
 211   parsers.
 212 * Added intestactionsdetail to action=query&prop=info to allow retrieving the
 213   reasons an action is not allowed.
 214 * Deprecated action=query&prop=info inprop=readable in favor of
 215   intestactions=read.
 216
 217 === Action API internal changes in 1.32 ===
 218 * Added 'ApiParseMakeOutputPage' hook.
 219 * Parameter names may no longer contain '{' or '}', as these are now used for
 220   templated parameters.
 221 * (T194950) Added 'ApiMaxLagInfo' hook.
 222 * The following methods now take a RevisionRecord rather than a Revision. No
 223   external callers are known.
 224   * ApiFeedContributions::feedItemAuthor()
 225   * ApiFeedContributions::feedItemDesc()
 226   * ApiQueryRevisionsBase::extractRevisionInfo()
 227 * The following deprecated methods have been removed:
 228   * ApiBase::profileIn() (deprecated in 1.25)
 229   * ApiBase::profileOut() (deprecated in 1.25)
 230   * ApiBase::safeProfileOut() (deprecated in 1.25)
 231   * ApiBase::profileDBIn() (deprecated in 1.25)
 232   * ApiBase::profileDBOut() (deprecated in 1.25)
 233   * ApiBase::dieUsage() (deprecated in 1.29)
 234   * ApiBase::dieUsageMsg() (deprecated in 1.29)
 235   * ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
 236   * ApiBase::getErrorFromStatus() (deprecated in 1.29)
 237   * ApiBase::parseMsg() (deprecated in 1.29)
 238   * ApiBase::setWarning() (deprecated in 1.29)
 239   * ApiPageSet::getInvalidTitles() (deprecated in 1.26)
 240   * ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
 241   * ApiUsageException::getCodeString() (deprecated in 1.29)
 242   * ApiUsageException::getMessageArray() (deprecated in 1.29)
 243 * Class UsageException, deprecated in 1.29, has been removed.
 244 * ApiErrorFormatter: Added getFormat() and newWithFormat(). In particular, you
 245   can now easily test $formatter->getFormat() === 'bc', and then call
 246   $formatter->newWithFormat( 'plaintext' ) to get a non-BC formatter.
 247
 248 === Languages updated in 1.32 ===
 249 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 250 Below only new and removed languages are listed, as well as changes to languages
 251 because of Phabricator reports.
 252
 253 * (T193566) Added language support for Ambonese Malay (abs).
 254 * (T194047) Added language support for Shawiya, Latin script (shy-latn).

 258 * (T201276) Added language support for Western Armenian (hyw).
 259 * (T201583) Added language support for Mon (mnw).
 260
 261 === Breaking changes in 1.32 ===
 262 * $wgRequestTime, deprecated in 1.25, was removed. Use
 263   $_SERVER['REQUEST_TIME_FLOAT'] or WebRequest::getElapsedTime() instead.
 264 * The MediaWikiI18N class, deprecated in 1.31, was removed.
 265 * QuickTemplate::setTranslator(), deprecated in 1.31, was removed. Use
 266   Skin::msg() instead.

 268 * wfShellExecDisabled(), deprecated in 1.30, was removed.
 269 * The type string for the parameter $lang of DateFormatter::getInstance,
 270   deprecated in 1.31, was removed.
 271 * The EDIT_TOKEN_SUFFIX constant deprecated in 1.27, was removed. Use
 272   MediaWiki\Session\Token::SUFFIX instead.
 273 * EditPage::isOouiEnabled() deprecated in 1.30, was removed.
 274 * mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl()
 275   instead.
 276 * (T61113) The following methods and constants from the Revision class, which
 277   were deprecated in 1.25, have now been removed:
 278   * Revision::getRawUser()
 279   * Revision::getRawUserText()
 280   * Revision::getRawComment()
 281 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use
 282   mw.msg() or mw.message() instead.
 283 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 284   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 285 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
 286   jquery.accessKeyLabel instead.
 287 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 288 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 289   with the Balancer tidy implementation. Both implementations were experimental,
 290   and were replaced by RemexHtml.
 291 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 292   removed. Use JobQueueGroup::singleton()->push() instead.
 293 * The jquery.footHovzer module, for mediawiki.debug, was removed.
 294 * The es5-shim module, empty and deprecated since 1.29, was removed.
 295 * the dom-level2-shim module, empty and deprecated since 1.29, was removed.
 296 * the json module, empty and deprecated since 1.29, was removed.
 297 * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was
 298   removed. Use mediawiki.widgets.visibleLengthLimit instead.
 299 * The jquery.farbtastic module, unused since 1.18, was removed.
 300 * The 'jquery.expandableField' module, unused since 1.22, was removed.
 301 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 302   any HTMLForm object rather than PreferencesForm.
 303 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 304   Use Wikimedia\Timestamp\TimestampException instead.
 305 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 306   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 307   The UtfNormal\Utils class from the utfnormal library should be used instead.
 308 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 309   from the UtfNormal\Constants class from the utfnormal library should be used
 310 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 311   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 312   values `true` and `false` respectively.
 313 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 314   were removed. Use the ParserCache class instead.
 315 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 316   instead.
 317 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 318   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 319 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 320   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 321   is no longer loaded by default. The Vector and MonoBook skins have made a
 322   minor change to implement the toggle feature with CSS instead. To restore
 323   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 324   or refer to T195256 for details on how to make the same change.
 325 * Hook 'EditPageBeforeEditChecks' was removed;
 326   use 'EditPageGetCheckboxesDefinition' instead.
 327 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 328   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 329 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 330   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 331   instead.
 332 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 333   CapsuleMultiselectWidget. The following methods may no longer be used:
 334   * setItemsFromData: Use setValue instead
 335   * getItemsData: Use getItems instead and get the data property
 336 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 337   removed.  Use addLink() instead.
 338 * Another two OutputPage methods, setPageTitleActionText() and
 339   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 340   ten years).  Use setHTMLTitle() directly.
 341 * The return value of OutputPage::adaptCdnTTL() has been removed. The
 342   value returned was misleading and probably not what any caller would
 343   have wanted.
 344 * All MagicWord static member variables have been removed.  Use appropriate
 345   hooks or MagicWordFactory methods instead.
 346 * MagicWord::clearCache() has been removed.  Instead, create a new
 347   MagicWordFactory, such as by calling
 348   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 349 * mw.util.init() has been removed. This function is not needed anymore and was
 350   a no-op function since 1.30.
 351 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 352   instead.
 353 * MediaWiki no longer supports a StartProfiler.php file. Instead, you can set
 354   $wgProfiler and $wgEnableProfileInfo.
 355 * The mw.loader.addSource() is now considered a private method, and no longer
 356   supports the `id, url` signature. Use the `Object` parameter instead.
 357 * The backwards-compatibility code in HTMLForm to add a drop-down control to an
 358   option that is not set to be a drop-down if the "mw-chosen" class is present,
 359   is now removed.
 360 * Several collations were removed. They were workarounds for bugs in the ICU
 361   library and they are no longer needed (as of ICU 57.1):
 362   * 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
 363   * 'xx-uca-et' (CollationEt) - use 'uca-et' instead
 364   * 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
 365 * LanguageCode::bcp47() now always returns a valid BCP 47 code.  This means
 366   that some MediaWiki-specific language codes, such as `simple`, are mapped
 367   into valid BCP 47 codes (eg `en-simple`).
 368 * The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated
 369   in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'.
 370   The ChangesListSpecialPage code for these legacy hooks, and their use in
 371   SpecialRecentchanges.php and SpecialWatchlist, was also removed:
 372   * ChangesListSpecialPage->getCustomFilters()
 373   * ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters()
 374   * ChangesListSpecialPage::customFilters
 375 * The global function wfUseMW, deprecated since 1.26, has now been removed. Use
 376   the "requires" property of static extension registration instead.
 377 * $wgSpecialPages no longer accepts array syntax, deprecated since 1.18.
 378 * The MailAddress constructor can no longer be called with a User object,
 379   behaviour which has been deprecated since 1.24.
 380 * LBFactory, deprecated since 1.28, has been removed. Instead, use
 381   Wikimedia\Rdbms\LBFactory.
 382 * The MimeMagic class, deprecated since 1.28 has been removed. Get a
 383   MimeAnalyzer instance from MediaWikiServices instead.
 384 * The '--tidy' option to maintenance/parse.php has been removed.  Tidying
 385   the output is now the default.  Use '--no-tidy' to bypass the tidy
 386   phase.
 387 * The global function wfErrorLog, deprecated since 1.25, has now been removed.
 388   Use MWLoggerLegacyLogger::emit or UDPTransport.
 389 * The hooks 'SpecialRecentChangesQuery' & 'SpecialWatchlistQuery', deprecated in
 390   1.23, were removed. Instead, use ChangesListSpecialPageStructuredFilters or
 391   ChangesListSpecialPageQuery.
 392 * The global function wfUsePHP, deprecated since 1.30, has now been removed. To
 393   assert a newer version of PHP than MediaWiki does, use extension registration.
 394 * The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been
 395   removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
 396 * DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
 397 * File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
 398 * The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use
 399   the hook 'SkinEditSectionLinks' instead.
 400 * The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
 401 * The global function wfRunHooks, deprecated since 1.25, has now been removed.
 402   Use Hooks::run().
 403 * The hook 'UnknownAction', deprecated since 1.19, has now been removed.
 404 * The hook 'ParserLimitReport', deprecated since 1.22, has been removed. Use
 405   the hooks 'ParserLimitReportPrepare' and 'ParserLimitReportFormat' instead.

 422 * Class UsageException, deprecated in 1.29, has been removed.
 423
 424 === Deprecations in 1.32 ===
 425 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 426   button is already marked as progressive.
 427 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 428   has been centralised to Skin::getDefaultModules(), which is now capable
 429   of queueing style modules as well.
 430 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 431   deprecated. Use addModules() instead.
 432 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 433   in extending classes is deprecated.  Extend related doSearch* methods
 434   instead.
 435 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 436   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 437   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 438   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 439   mediawiki.api.messages, and mediawiki.api.rollback.
 440 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 441   to use it.
 442 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 443   with the 'unwatch' action parameter instead.
 444 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 445   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 446 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 447 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 448 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 449   of the namespaced classes provided by the wikimedia/xmp-reader library.
 450 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 451   use foreach on the SearchResultSet, or the extractResults method. Extending
 452   code should override extractResults.
 453 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 454   implementations must subclass SearchResultSet for their purposes.
 455 * SearchResult::setExtensionData argument has been changed from accepting an
 456   array to accepting a Closure that returns the array when called.
 457 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 458   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 459   generate cryptographically secure random byte sequences.
 460 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 461   instead.
 462 * Language::markNoConversion() is deprecated.  It confused readers because
 463   it had unexpected behavior (only marking text if it looked like a URL)
 464   and was only used in a single place in the code.  Use
 465   LanguageConverter::markNoConversion() instead.
 466 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 467   hard deprecated in this release.  It has been split into two similar
 468   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 469   which measure length in characters and bytes, respectively.  Use
 470   Language::truncateForVisual() when possible to provide equity to users
 471   of multibyte scripts.
 472 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 473   context title is unset is now deprecated; anything creating an EditPage
 474   instance should set the context title via ::setContextTitle().
 475 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 476 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 477   are deprecated. These concepts are obsolete and have no replacement.
 478 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 479 * The following methods of OutputPage are now deprecated in favour
 480   of using showFatalError directly: OutputPage::showFileDeleteError()
 481   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 482   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 483 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 484   classes are now deprecated. Use a Closure instead.
 485 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 486   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 487 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 488   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 489   the Parsoid v3 API in May 2015.
 490 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 491   $formDescriptor instead.
 492 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 493   to running searchText. This method was mainly implemented to support the
 494   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 495   logic as it should be handled internally by SearchEngine implementations
 496   supporting this feature. SearchEngine implementations should no longer
 497   override this methods.
 498 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 499   to running searchText/searchTitle.
 500 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 501   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 502 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 503   use array_filter() directly.
 504 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 505   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 506 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 507   Set $wgShowExceptionDetails instead.
 508 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 509   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 510   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 511   getOldRevision() / getNewRevision() for the first four (note that the
 512   revision ones return a RevisionRecord, not a Revision), do your own lookup
 513   for page/content.
 514 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 515   just enable the PHP extension, and it will be autodetected.
 516 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 517   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 518   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 519   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 520   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 521   to customize page-level diff properties (such as the navigation header).
 522 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 523 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 524   methods instead.
 525 * PasswordFactory::init is deprecated. To get a password factory with the
 526   standard configuration, use MediaWikiServices::getPasswordFactory.
 527 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 528   instead.
 529 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 530 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 531   instead.
 532 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 533 * All SpecialPageFactory static methods are deprecated. Instead, call the
 534   methods on a SpecialPageFactory instance, which may be obtained from
 535   MediaWikiServices.
 536 * mw.user.stickyRandomId was renamed to the more explicit
 537   mw.user.getPageviewToken to better capture its function.
 538 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 539   Content object should be passed instead.
 540 * (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
 541   previously used by OOUI HTMLForm fields, are now deprecated. Use
 542   'help', 'help-message', 'help-messages' instead.
 543 * (T197179) HTMLFormField::getNotices() is now deprecated.
 544 * The jquery.localize module is now deprecated. Use jquery.i18n instead.
 545 * The SecondaryDataUpdates hook was deprecated in favor of RevisionDataUpdates,
 546   or overriding ContentHandler::getSecondaryDataUpdates (T194038).
 547 * The WikiPageDeletionUpdates hook was deprecated in favor of
 548   PageDeletionDataUpdates, or overriding ContentHandler::getDeletionDataUpdates
 549   (T194038).
 550 * Content::getSecondaryDataUpdates has been deprecated in favor of
 551   ContentHandler::getSecondaryDataUpdates() for overriding by extensions
 552   (T194038).
 553   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 554 * Content::getDeletionUpdates has been deprecated in favor of
 555   ContentHandler::getDeletionUpdates() for overriding by extensions (T194038).
 556   Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
 557 * (T198214) Old Tidy-related configuration settings, which were soft-deprecated
 558   in MediaWiki 1.26, have now been hard deprecated. This affects $wgUseTidy,
 559   $wgTidyBin, $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy. Use
 560   $wgTidyConfig instead.
 561 * All Tidy configurations other than Remex have been hard deprecated;
 562   future parsers will not emit compatible output for these configurations.
 563 * (T198214) OutputPage::addWikiText(), OutputPage::addWikiTextWithTitle(),
 564   and OutputPage::addWikiTextTitle() have been deprecated, since they
 565   can result in untidy output.  In addition OutputPage::addWikiTextTidy()
 566   and OutputPage::addWikiTextTitleTidy() was deprecated to make naming new
 567   methods consistent.  Use OutputPage::addWikiTextAsInterface() or
 568   OutputPage::addWikiTextAsContent() instead, which ensures the output is
 569   tidy and clarifies whether content-language specific postprocessing should
 570   be done on the text.
 571 * QuickTemplate::msgHtml() and BaseTemplate::msgHtml() have been deprecated
 572   as they promote bad practises. I18n messages should always be properly
 573   escaped.
 574 * Skin::getDynamicStylesheetQuery() has been deprecated. It always
 575   returns action=raw&ctype=text/css which callers should use directly.
 576 * Class LegacyFormatter is deprecated.
 577 * Use of CommentStore::insertWithTempTable() with 'img_description' is
 578   deprecated. Use CommentStore::insert() instead.
 579 * Language::setCode is deprecated as public function. Use Language::factory
 580   to create a new Language object with a different language code.
 581 * Several classes have been moved from the MediaWiki\Storage\ namespace to the
 582   MediaWiki\Revision\ namespace. The old class names are aliased for
 583   compatibility, but are deprecated. Classes are IncompleteRevisionException,
 584   MutableRevisionRecord, MutableRevisionSlots, RevisionAccessException,
 585   RevisionArchiveRecord, RevisionFactory, RevisionLookup, RevisionRecord,
 586   RevisionSlots, RevisionStore, RevisionStoreRecord, SlotRecord, and
 587   SuppressedDataException.
 588 * When using OOUI HTMLForm containing an 'info' field which uses the 'rawrow'
 589   option, it is now deprecated to give its contents (the 'default' option)
 590   as a string. They should be given as a OOUI\FieldLayout object instead.
 591   Notably, this affects fields defined in the 'GetPreferences' hook, because
 592   Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
 593 * In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is
 594   deprecated. For the $lang parameter, types other than Language are
 595   deprecated.
 596 * The $wgUseKeyHeader configuration option and the
 597   OutputPage::getKeyHeader() method have been deprecated; the relevant
 598   draft IETF spec expired without becoming a standard.
 599 * Deprecated API action=query&prop=info inprop=readable in favor of
 600   intestactions=read.
 601
 602 === Other changes in 1.32 ===
 603 * (T198811) The following tables have had their UNIQUE indexes turned into
 604   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 605   protected_titles and site_identifiers.
 606 * OOUI HTMLForm will now display help text inline after the input field,
 607   rather than in a popup. Previous behavior can be restored by using
 608   `'help-inline' => false`.
 609 * The archive table's ar_rev_id field is now unique.
 610 * Special:BotPasswords now requires reauthentication.
 611 * (T174023) Multi-Content Revision (MCR) capabilities were introduced into the
 612   storage layer and have basic support for display. No user interface exists
 613   yet for creating or managing content in slots beides the main slot. See
 614   <https://www.mediawiki.org/wiki/Multi-Content_Revisions> for more
 615   information.
 616 * The image_comment_temp database table is merged into the image table and
 617   deprecated. Since access should be mediated by the CommentStore class, this
 618   change shouldn't affect external code.
 619 * (T206147) Database::close() will no longer commit any open transactions.
 620
 621 == Compatibility ==
 622 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 623 supported, it is generally advised to use PHP 7.0.0 or later for long term
 624 support.
 625
 626 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 627 but support for them is somewhat less mature. There is experimental support for
 628 Oracle and Microsoft SQL Server.
 629
 630 The supported versions are:
 631
 632 * MySQL 5.5.8 or later
 633 * PostgreSQL 9.2 or later
 634 * SQLite 3.3.7 or later
 635 * Oracle 9.0.1 or later
 636 * Microsoft SQL Server 2005 (9.00.1399)
 637
 638 == Upgrading ==
 639 1.32 has several database changes since 1.31, and will not work without schema
 640 updates. Note that due to changes to some very large tables like the revision
 641 table, the schema update may take quite long (minutes on a medium sized site,
 642 many hours on a large site).
 643
 644 Don't forget to always back up your database before upgrading!
 645
 646 See the file UPGRADE for more detailed upgrade instructions, including
 647 important information when upgrading from versions prior to 1.11.
