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
  40 ==== Removed configuration ====
  41 * $wgEnableAPI and $wgEnableWriteAPI – These settings, deprecated in 1.31,
  42   have been removed. (T115414)
  43 * $wgSiteSupportPage – This setting, unused since 1.5, was removed.
  44 * $wgBrowserBlacklist – This setting, deprecated in 1.30, was removed.
  45 * $wgExperimentalHtmlIds – This setting, deprecated since 1.30, was removed.
  46   The 'html5-legacy' value for $wgFragmentMode is no longer accepted.
  47 * $wgPasswordSenderName - This setting, ignored since 1.23 by MediaWiki and
  48   most extensions, is no longer set. Instead, you can modify the system
  49   message `emailsender`.
  50 * $wgTidyConfig – The experimental Html5Internal and Html5Depurate tidy drivers
  51   were removed. RemexHtml, which is the default, should be used instead.
  52
  53 === New features in 1.32 ===
  54 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  55   using a particular page during edit previews.
  56 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  57   to true.
  58 * Added 'ApiParseMakeOutputPage' hook.
  59 * (T174313) Added checkbox on Special:ListUsers to display only users in
  60   temporary user groups.
  61 * (T152462) A cookie can now be set when an IP user is blocked to track that
  62   user if they move to a new IP address. This is disabled by default.
  63 * (T194950) Added 'ApiMaxLagInfo' hook.
  64 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  65   reauthenticating.
  66 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  67   getLoginSecurityLevel() returns non-false.
  68 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  69   &$query and &$widthOption, allowing extensions even finer control over the
  70   resulting HTML code.
  71 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
  72   if the [mark as patrolled] link should be shown at the footer of patrollable
  73   pages.
  74 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
  75   is now passed by reference, allowing extensions to modify or even unset it.
  76 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
  77   modify the return value of OutputPage#getHeadLinksArray in order to add,
  78   remove or otherwise alter the elements to be output in the page <head>.
  79 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
  80   additional links to the subtitle of a history page.
  81 * The 'GetLinkColours' hook now receives an additional $title parameter,
  82   the Title object of the page being parsed, on which the links will be shown.
  83 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
  84   render diffs between two Content objects, and DifferenceEngine::setRevisions()
  85   to render diffs between two custom (potentially multi-content) revisions.
  86   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
  87 * Added a temporary action=mcrundo to the web UI, as the normal undo logic
  88   can't yet handle MCR and deadlines are forcing is to put off fixing that.
  89   This action should be considered deprecated and should not be used directly.
  90 * Extensions overriding ContentHandler::getUndoContent() will need to be
  91   updated for the changed method signature.
  92
  93 === External library changes in 1.32 ===
  94
  95 ==== New external libraries ====
  96 * Added wikimedia/xmp-reader 0.6.0
  97 * …
  98
  99 ==== Changed external libraries ====
 100 * Updated qunitjs from 2.4.0 to 2.6.2.
 101 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
 102 ** ScopedCallback objects can no longer be serialized.
 103 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
 104 * Updated mediawiki/mediawiki-codesniffer from v20.0.0 to v21.0.0.
 105 * Updated composer/spdx-licenses from 1.3.0 to 1.4.0.

 108 * Updated wikimedia/remex-html from 1.0.3 to 2.0.0.
 109 * Updated jquery from v3.2.1 to v3.3.1.
 110
 111 ==== Removed external libraries ====
 112 * …
 113
 114 === Bug fixes in 1.32 ===
 115 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 116   getLoginSecurityLevel() returns non-false.
 117
 118 === Action API changes in 1.32 ===
 119 * Added templated parameters.
 120   * A module can define a templated parameter like "{fruit}-quantity", where
 121     the actual parameters recognized correspond to the values of a multi-valued
 122     parameter. Then clients can make requests like
 123     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 124   * action=paraminfo will return templated parameter definitions separately
 125     from normal parameters. All parameter definitions now include an "index"
 126     key to allow clients to maintain parameter ordering when merging normal and
 127     templated parameters.
 128 * It is now an error to submit too many values for a multi-valued parameter.
 129   This has generated a warning since MediaWiki 1.14.
 130 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 131   longer use the action module's custom response format, for the few modules
 132   that use custom formatters that handle errors.
 133 * (T198935) User list preferences such as `email-blacklist` and similar
 134   extension preferences are no longer represented as arrays when returned by
 135   action=query&meta=userinfo&uiprop=options.
 136 * 'missingparam' errors will now use the prefixed parameter name in the code
 137   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 138   than "nofoo" and "The 'foo' parameter must be set".
 139 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 140   multi-content revision slots for which content should be returned. It also
 141   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 142   warning will be issued if rvprop=content or rvprop=contentmodel are used
 143   without rvslots.
 144 * The rvcontentformat parameter to action=query&prop=revisions has been
 145   deprecated. Clients should be prepared to deal with the default format for
 146   relevant models.
 147 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 148   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 149   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 150 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 151   action=query&list=alldeletedrevisions are changed similarly to
 152   &prop=revisions (see the three previous items).
 153 * (T174032) action=compare now supports multi-content revisions.
 154   * It has a 'slots' parameter to select diffing of individual slots. The
 155     default behavior is to return one combined diff.
 156   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 157     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 158     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 159     slots have text supplied and the corresponding templated parameters for
 160     each slot.
 161   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 162     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 163     instead expand the given text as if for a section edit. This effectively
 164     declines T183823 in favor of T185723.
 165
 166 === Action API internal changes in 1.32 ===
 167 * Added 'ApiParseMakeOutputPage' hook.
 168 * Parameter names may no longer contain '{' or '}', as these are now used for
 169   templated parameters.
 170 * (T194950) Added 'ApiMaxLagInfo' hook.
 171 * Added 'ApiParseMakeOutputPage' hook.
 172 * The following methods now take a RevisionRecord rather than a Revision. No
 173   external callers are known.
 174   * ApiFeedContributions::feedItemAuthor()
 175   * ApiFeedContributions::feedItemDesc()
 176   * ApiQueryRevisionsBase::extractRevisionInfo()
 177
 178 === Languages updated in 1.32 ===
 179 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 180 Below only new and removed languages are listed, as well as changes to languages
 181 because of Phabricator reports.
 182
 183 * (T193566) Added language support for Ambonese Malay (abs).
 184 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 185 * (T195940) Added language support for Batak Mandailing (btm).
 186 * (T137491) Added language support for Standard Moroccan Amazigh (zgh).
 187 * (T198132) Added language support for Manipuri (mni).
 188 * (T201276) Added language support for Western Armenian (hyw).
 189 * (T201583) Added language support for Mon (mnw).
 190
 191 === Breaking changes in 1.32 ===

 208   * Revision::getRawUser()
 209   * Revision::getRawUserText()
 210   * Revision::getRawComment()
 211 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use

 213 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 214   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 215 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
 216   jquery.accessKeyLabel instead.
 217 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 218 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 219   with the Balancer tidy implementation. Both implementations were experimental,
 220   and were replaced by RemexHtml.
 221 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 222   removed. Use JobQueueGroup::singleton()->push() instead.
 223 * The jquery.footHovzer module, for mediawiki.debug, was removed.
 224 * The es5-shim module, empty and deprecated since 1.29, was removed.
 225 * the dom-level2-shim module, empty and deprecated since 1.29, was removed.
 226 * the json module, empty and deprecated since 1.29, was removed.
 227 * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was

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

 233 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 234   any HTMLForm object rather than PreferencesForm.
 235 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 236   Use Wikimedia\Timestamp\TimestampException instead.
 237 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 238   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 239   The UtfNormal\Utils class from the utfnormal library should be used instead.
 240 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 241   from the UtfNormal\Constants class from the utfnormal library should be used
 242 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 243   from ResourceLoader. Instead, use `@import` statements in LESS to import
 244   files directly from nearby directories within the same project.
 245 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
 246   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
 247   the ResourceLoaderModule::getLessVars() method.
 248 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 249   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 250   values `true` and `false` respectively.
 251 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 252   were removed. Use the ParserCache class instead.
 253 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 254   instead.
 255 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 256   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 257 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 258   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 259   is no longer loaded by default. The Vector and MonoBook skins have made a
 260   minor change to implement the toggle feature with CSS instead. To restore
 261   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 262   or refer to T195256 for details on how to make the same change.
 263 * Hook 'EditPageBeforeEditChecks' was removed;
 264   use 'EditPageGetCheckboxesDefinition' instead.
 265 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 266   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 267 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 268   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 269   instead.
 270 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 271   CapsuleMultiselectWidget. The following methods may no longer be used:
 272   * setItemsFromData: Use setValue instead
 273   * getItemsData: Use getItems instead and get the data property
 274 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 275   removed.  Use addLink() instead.
 276 * Another two OutputPage methods, setPageTitleActionText() and
 277   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 278   ten years).  Use setHTMLTitle() directly.
 279 * All MagicWord static member variables have been removed.  Use appropriate
 280   hooks or MagicWordFactory methods instead.
 281 * MagicWord::clearCache() has been removed.  Instead, create a new
 282   MagicWordFactory, such as by calling
 283   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 284 * mw.util.init() has been removed. This function is not needed anymore and was
 285   a no-op function since 1.30.
 286 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 287   instead.
 288 * MediaWiki no longer supports a StartProfiler.php file.
 289   Define $wgProfiler via LocalSettings.php instead.
 290 * The mw.loader.addSource() is now considered a private method, and no longer
 291   supports the `id, url` signature. Use the `Object` parameter instead.
 292
 293 === Deprecations in 1.32 ===
 294 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 295   button is already marked as progressive.
 296 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 297   has been centralised to Skin::getDefaultModules(), which is now capable
 298   of queueing style modules as well.
 299 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 300   deprecated. Use addModules() instead.
 301 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 302   in extending classes is deprecated.  Extend related doSearch* methods
 303   instead.
 304 * CollationFa has been removed completely as it's not needed anymore
 305 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 306   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 307   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 308   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 309   mediawiki.api.messages, and mediawiki.api.rollback.
 310 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 311   to use it.
 312 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 313   with the 'unwatch' action parameter instead.
 314 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 315   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 316 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 317 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 318 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 319   of the namespaced classes provided by the wikimedia/xmp-reader library.
 320 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 321   use foreach on the SearchResultSet, or the extractResults method. Extending
 322   code should override extractResults.
 323 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 324   implementations must subclass SearchResultSet for their purposes.
 325 * SearchResult::setExtensionData argument has been changed from accepting an
 326   array to accepting a Closure that returns the array when called.
 327 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 328   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 329   generate cryptographically secure random byte sequences.
 330 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 331   instead.
 332 * Language::markNoConversion() is deprecated.  It confused readers because
 333   it had unexpected behavior (only marking text if it looked like a URL)
 334   and was only used in a single place in the code.  Use
 335   LanguageConverter::markNoConversion() instead.
 336 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 337   hard deprecated in this release.  It has been split into two similar
 338   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 339   which measure length in characters and bytes, respectively.  Use
 340   Language::truncateForVisual() when possible to provide equity to users
 341   of multibyte scripts.
 342 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 343   context title is unset is now deprecated; anything creating an EditPage
 344   instance should set the context title via ::setContextTitle().
 345 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 346 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 347   are deprecated. These concepts are obsolete and have no replacement.
 348 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 349 * The following methods of OutputPage are now deprecated in favour
 350   of using showFatalError directly: OutputPage::showFileDeleteError()
 351   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 352   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 353 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 354   classes are now deprecated. Use a Closure instead.
 355 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 356   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 357 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 358   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 359   the Parsoid v3 API in May 2015.
 360 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 361   $formDescriptor instead.
 362 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 363   to running searchText. This method was mainly implemented to support the
 364   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 365   logic as it should be handled internally by SearchEngine implementations
 366   supporting this feature. SearchEngine implementations should no longer
 367   override this methods.
 368 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 369   to running searchText/searchTitle.
 370 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 371   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 372 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 373   use array_filter() directly.
 374 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 375   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 376 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 377   Set $wgShowExceptionDetails instead.
 378 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 379   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 380   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 381   getOldRevision() / getNewRevision() for the first four (note that the
 382   revision ones return a RevisionRecord, not a Revision), do your own lookup
 383   for page/content.
 384 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 385   just enable the PHP extension, and it will be autodetected.
 386 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 387   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 388   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 389   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 390   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 391   to customize page-level diff properties (such as the navigation header).
 392 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 393 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 394   methods instead.
 395 * PasswordFactory::init is deprecated. To get a password factory with the
 396   standard configuration, use MediaWikiServices::getPasswordFactory.
 397 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 398   instead.
 399 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 400 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 401   instead.
 402 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 403 * All SpecialPageFactory static methods are deprecated. Instead, call the
 404   methods on a SpecialPageFactory instance, which may be obtained from
 405   MediaWikiServices.
 406 * mw.user.stickyRandomId was renamed to the more explicit
 407   mw.user.getPageviewToken to better capture its function.
 408 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 409   Content object should be passed instead.
 410 * (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
 411   previously used by OOUI HTMLForm fields, are now deprecated. Use
 412   'help', 'help-message', 'help-messages' instead.
 413 * (T197179) HTMLFormField::getNotices() is now deprecated.
 414 * The jquery.localize module is now deprecated. Use jquery.i18n instead.
 415
 416 === Other changes in 1.32 ===
 417 * (T198811) The following tables have had their UNIQUE indexes turned into
 418   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 419   protected_titles and site_identifiers.
 420 * OOUI HTMLForm will now display help text inline after the input field,
 421   rather than in a popup. Previous behavior can be restored by using
 422   `'help-inline' => false`.
 423 * The archive table's ar_rev_id field is now unique.
 424 * Special:BotPasswords now requires reauthentication.
 425 * …

 427 == Compatibility ==
 428 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 429 supported, it is generally advised to use PHP 7.0.0 or later for long term
 430 support.
 431
 432 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 433 but support for them is somewhat less mature. There is experimental support for
 434 Oracle and Microsoft SQL Server.
 435
 436 The supported versions are:
 437
 438 * MySQL 5.5.8 or later
 439 * PostgreSQL 9.2 or later
 440 * SQLite 3.3.7 or later
 441 * Oracle 9.0.1 or later
 442 * Microsoft SQL Server 2005 (9.00.1399)
 443
 444 == Upgrading ==
 445 1.32 has several database changes since 1.31, and will not work without schema
 446 updates. Note that due to changes to some very large tables like the revision
 447 table, the schema update may take quite long (minutes on a medium sized site,
 448 many hours on a large site).
 449
 450 Don't forget to always back up your database before upgrading!
 451
 452 See the file UPGRADE for more detailed upgrade instructions, including
 453 important information when upgrading from versions prior to 1.11.
