Release notes/1.32/fr

Problèmes connus

 * (T215566) Pour les nouvelles installations utilisant MySql/MariaDB, le programme d'installation ne peut pas créer la base de données. Les utilisateurs qui tentent d'installer MediaWiki 1.32 sur une nouvelle base de données doivent d'abord créer la base de données.

Changements depuis MediaWiki 1.32.0-rc.0

 * (T209885) Empêche le dysfonctionnement de populateSearchIndex.php une fois la migration de l'acteur démarrée.
 * (T210998) Initialise proprement $wgLanguageCode dans le LocalSettings.php généré si --lang est utilisé avec l'installeur en ligne de commande (install.php).

Nouvelle configuration

 * – La qualité des vignettes JPEG est dorénavant configurable avec ce paramètre. La valeur par défaut est 80, qui équivaut à la qualité des vignettes JPEG générées précédemment par ImageMagick. La qualité des vignettes JPEG générées par GD était de 95 avant, mais maintenant il utilise également le paramètre.
 * - Ceci détermine s'il faut installer un cookie quand un utilisateur IP est bloqué. Ainsi un utilisateur bloqué restera bloqué même s'il migre vers une nouvelle adresse IP.
 * – Ce nouveau paramètre de configuration est ajouté pour lister les messages qui sont affichés sous format brut HTML.
 * and – You can now define a "Content Security Policy" for your wiki. This adds a defense-in-depth feature to stop an attacker who has found a bug in the parser allowing them to insert malicious attributes. Disabled by default. (T135963)
 * – Un nouveau groupe utilisateur, 'interface-admin', est ajouté pour contrôler l'accès au CSS/JS sur tout le site (y compris la modification du CSS/JS des autres utilisateurs). Aucun autre groupe n'a 'editsitecss', 'editusercss', 'editsitejs' ou 'edituserjs' par défaut.
 * – Un nouveau groupe de droits, 'editsiteconfig', est ajouté pour attibuer les droits ci-dessus.
 * – Un groupe par défaut de base de données, utilisé par les scripts de maintenance.
 * – Ce nouveau paramètre de configuration vous permet le profiling côté client pour les modules JavaScript; il est positionné à off par défaut.
 * (T193868) — Ce paramètre temporaire de configuration permet aux administrateurs système de migrer graduellement le schéma des tables de la base de données en fonction du stockage des balises de modification.
 * (T199334) — This temporary configuration setting allows sysadmins to enable the caching of Special:Tags via the new change_tag_def table.

Configuration modifiée

 * – Ce paramètre obsolète en 1.31 est ignoré maintenant.
 * – The default watchlist view time (watchlistdays) has been increased from 3 to 7 days. (T194414)
 * – The right to edit sitewide Javascript (e.g. MediaWiki:Common.js), CSS or JSON was separated from 'editinterface' and is available under 'editsitejs'/'editsitecss'/'editsitejson'. Having 'editinterface' is still necessary to edit such pages.
 * now defaults to writing both the old and the new schema, but reading the new schema, so Multi-Content Revisions (MCR) are now functional per default. The new default value of the setting is SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW.
 * n'accepte plus MIGRATION_WRITE_BOTH ni MIGRATION_WRITE_NEW. A la place, il utilise SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_OLD and SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW pour les étapes intermédiaires de la migration.
 * – The default table options now use the binary charset. The default was already overridden in the installer-generated LocalSettings.php, and so is always set to binary after the installer UI option was removed. The default value is only used when the installer installs an extension.
 * — The location of the default popular passwords file has been moved to be in line with other non-PHP files used by libraries and classes.
 * is now disabled by default, as it opens up a hole for potential privacy leaks by administrators. You can check "MediaWiki:External image whitelist" on your wiki to see whether the feature was ever used, and whether it needs to be re-enabled.

Configuration supprimée

 * et – Ces paramètres, obsolètes en 1.31, ont été supprimés. (T115414)
 * – Ce paramètre n'est plus utilisé depuis la 1.5 et a été supprimé.
 * – Ce paramètre obsolète en 1.30, a été supprimé.
 * – This setting, deprecated since 1.30, was removed. The 'html5-legacy' value for is no longer accepted.
 * - Ce paramètre ignoré depuis 1.23 par MediaWiki et la plupart des extensions, n'est plus initialisé. A la place vous pouvez modifier le message système `emailsender`.
 * – Les pilotes Tidy expérimentaux Html5Internal et Html5Depurate ont été supprimés. RemexHtml, est le pilote par défaut et doit être utilisé en remplacement.
 * (T181318) The setting and its appendage to various script and style URLs in OutputPage, deprecated in 1.31, was removed.
 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed from ResourceLoader. Instead, use `@import` statements in LESS to import files directly from nearby directories within the same project.
 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated since 1.30, was removed. Instead, to expose variables from PHP to LESS, use the ResourceLoaderModule::getLessVars method.
 * – Ce paramètre n'est plus utilisé depuis MediaWiki 1.18 et a été supprimé.
 * Two temporary variables for deploying the feature of filters on change lists, introduced in MediaWiki 1.30 and  in 1.31, were removed.

Nouvelles fonctionnalités dans 1.32

 * (T112474) Generalized the ResourceLoader mechanism for overriding modules using a particular page during edit previews.
 * (T12331) Vous pouvez maintenant journaliser les événements de création de page en fixant à vrai.
 * Accroche 'ApiParseMakeOutputPage' ajoutée.
 * (T174313) Ajout d'une case à cocher sur Special:ListUsers pour n'afficher que les utilisateurs des groupes temporaires d'utilisateurs.
 * (T152462) Un cookie peut maintenant être installé quand un utilisateur IP est bloqué afin de tracer cet utilisateur s'il migre vers une nouvelle adresse IP. Ceci est désactivé par défaut.
 * (T194950) Accroche 'ApiMaxLagInfo' ajoutée.
 * SpecialPage::checkLoginSecurityLevel préserve dorénavant les données du POST lors de la réauthentification.
 * FormSpecialPage::execute appelle dorénavant checkLoginSecurityLevel si getLoginSecurityLevel rend une valeur différente de faux.
 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser, &$query and &$widthOption, allowing extensions even finer control over the resulting HTML code.
 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine if the [mark as patrolled] link should be shown at the footer of patrollable pages.
 * Le tableau des options cachées ($opts) passé à l'accroche 'SpecialSearchPowerBox' est maintenant passé par référence, ce qui permet aux extensions de le modifier ou même de le réinitialiser.
 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to modify the return value of OutputPage#getHeadLinksArray in order to add, remove or otherwise alter the elements to be output in the page.
 * (T28934) L'accroche 'HistoryPageToolLinks' permet aux extensions d'ajouter des liens supplémentaires au sous-titre d'une page historique.
 * The 'GetLinkColours' hook now receives an additional $title parameter, the Title object of the page being parsed, on which the links will be shown.
 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to render diffs between two Content objects, and DifferenceEngine::setRevisions to render diffs between two custom (potentially multi-content) revisions. Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
 * Ajout temporaire de action=mcrundo à l'interface utilisateur web, car la logique normale d'annulation ne peut pas encore traiter MCR et les échéances nous obligent à différer la résolution de ce problème. Cette action doit être considérée comme obsolète et ne doit pas être utilisée directement.
 * Les extensions qui réécrasent ContentHandler::getUndoContent devront être mises à jour à cause de la signature modifiée de la méthode.
 * Ajout d'une nouvelle accroche, 'UserGetRightsRemove', qui peut être utilisée pour supprimer des droits de l'utilisateur. A la différence de 'UserGetRights' elle garantit que les droits retirés ne seront pas rétablis.

Corrections de bugs dans 1.32

 * SpecialPage::execute will now only call checkLoginSecurityLevel if getLoginSecurityLevel returns non-false.
 * (T43720, T46197) Amélioration de la gestion de l'affichage du titre de page pour les pages de catégorie
 * (T65080) Fixed resetting options of some types via API action=options.

Modifications de l'API Action dans 1.32

 * Ajout de paramètres de modèle.
 * A module can define a templated parameter like "{fruit}-quantity", where the actual parameters recognized correspond to the values of a multi-valued parameter. Then clients can make requests like "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 * action=paraminfo will return templated parameter definitions separately from normal parameters. All parameter definitions now include an "index" key to allow clients to maintain parameter ordering when merging normal and templated parameters.
 * It is now an error to submit too many values for a multi-valued parameter. This has generated a warning since MediaWiki 1.14.
 * Assertion failures from the 'assert' and 'assertuser' parameters will no longer use the action module's custom response format, for the few modules that use custom formatters that handle errors.
 * (T198935) User list preferences such as `email-blacklist` and similar extension preferences are no longer represented as arrays when returned by action=query&meta=userinfo&uiprop=options.
 * 'missingparam' errors will now use the prefixed parameter name in the code and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather than "nofoo" and "The 'foo' parameter must be set".
 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the multi-content revision slots for which content should be returned. It also has a new rvprop, 'roles', to indicate which roles have slots. A deprecation warning will be issued if rvprop=content or rvprop=contentmodel are used without rvslots.
 * The rvcontentformat parameter to action=query&prop=revisions has been deprecated. Clients should be prepared to deal with the default format for relevant models.
 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse, rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and action=query&list=alldeletedrevisions are changed similarly to &prop=revisions (see the three previous items).
 * (T174032) « action=compare » supporte maintenant les révisions multi-contenu.
 * It has a 'slots' parameter to select diffing of individual slots. The default behavior is to return one combined diff.
 * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat', 'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters are deprecated. Specify the new 'fromslots' and 'toslots' to identify which slots have text supplied and the corresponding templated parameters for each slot.
 * The behavior of 'fromsection' and 'tosection' of extracting one section's content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}' instead expand the given text as if for a section edit. This effectively declines T183823 in favor of T185723.
 * (T198214) The 'disabletidy' parameter to action=parse has been deprecated; untidy output will not be supported by future wikitext parsers.
 * Ajouté intestactionsdetail à action=query&prop=info pour autoriser de récupérer les raisons pour lesquelles une action n'est pas autorisée.
 * Obsolète action=query&prop=info inprop=readable est remplacé par intestactions=read.

Changements internes de l'API "Action" dans 1.32

 * Accroche 'ApiParseMakeOutputPage' ajoutée.
 * Les noms de paramètres ne peuvent plus contenir '{' ni '}', qui sont réservés aux paramètres des modèles.
 * (T194950) Accroche 'ApiMaxLagInfo' ajoutée.
 * The following methods now take a RevisionRecord rather than a Revision. No external callers are known.
 * ApiFeedContributions::feedItemAuthor
 * ApiFeedContributions::feedItemDesc
 * ApiQueryRevisionsBase::extractRevisionInfo
 * Les méthodes obsolètes suivantes ont été supprimées :
 * ApiBase::profileIn
 * ApiBase::profileOut
 * ApiBase::safeProfileOut
 * ApiBase::profileDBIn
 * ApiBase::profileDBOut
 * ApiBase::dieUsage
 * ApiBase::dieUsageMsg

 * ApiPageSet::getInvalidTitles
 * ApiQueryLogEvents::addLogParams
 * ApiUsageException::getCodeString
 * ApiUsageException::getMessageArray
 * La classe UsageException, obsolète en 1.29, a été supprimée.
 * ApiErrorFormatter: Added getFormat and newWithFormat. In particular, you can now easily test $formatter->getFormat === 'bc', and then call $formatter->newWithFormat( 'plaintext' ) to get a non-BC formatter.

Langues mises à jour dans 1.32
MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Phabricator reports.

 * The return value of OutputPage::adaptCdnTTL has been removed. The value returned was misleading and probably not what any caller would have wanted.
 * Toutes les variables des membres statiques de MagicWord ont été supprimées. Utilisez les accroches appropriées ou les méthodes de MagicWordFactory à la place.
 * MagicWord::clearCache a été supprimé. A la place, créez un nouveau MagicWordFactory, en appelant resetServiceForTesting( 'MagicWordFactory' ) sur un MediaWikiServices.

 * 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
 * LanguageCode::bcp47 now always returns a valid BCP 47 code. This means that some MediaWiki-specific language codes, such as `simple`, are mapped into valid BCP 47 codes (eg `en-simple`).
 * The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters', deprecated in 1.23, were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'. The ChangesListSpecialPage code for these legacy hooks, and their use in SpecialRecentchanges.php and SpecialWatchlist, was also removed:
 * ChangesListSpecialPage->getCustomFilters
 * ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters
 * ChangesListSpecialPage::customFilters
 * The global function wfUseMW, deprecated since 1.26, has now been removed. Use the "requires" property of static extension registration instead.
 * no longer accepts array syntax, deprecated since 1.18.
 * Le constructeur MailAddress ne peut plus être appelé avec un objet User, ce comportement était obsolète depuis 1.24.
 * LBFactory, obsolète depuis 1.28, a été supprimé. Remplacez par Wikimedia\Rdbms\LBFactory.

 * The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
 * DeferredUpdates::setImmediateMode, deprecated since 1.29, has been removed.
 * File / MediaHandler::getStreamHeaders, deprecated since 1.30, was removed.
 * The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use the hook 'SkinEditSectionLinks' instead.
 * The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
 * The global function wfRunHooks, deprecated since 1.25, has now been removed. Use Hooks::run.
 * The hook 'UnknownAction', deprecated since 1.19, has now been removed.

 * ApiUsageException::getCodeString
 * ApiUsageException::getMessageArray
 * Class UsageException, deprecated in 1.29, has been removed.
 * MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The old "bulletin board style toolbar", known as "the 2006 wikitext editor", has been removed, and instead sysadmins will be required to choose one (or more) of the several extensions available for this purpose if they need the functionality. The MediaWiki "tarball" releases have included the replacement extension for this, the WikiEditor extension aka "the 2010 wikitext editor", for many years now. As part of this, several parts of MediaWiki have been removed or simplified:
 * The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer available; if an extension adds a toolbar via the EditPageBeforeEditToolbar hook, it will be shown; extensions should provide a specific user preference to disable themselves as needed.
 * The public methods Language::getImageFile and ::getImageFiles, and the related specification of $imageFiles within individual languages' code file, as well as the referenced static media assets, all of which were only used inside MediaWiki itself for providing the icons for the old toolbar, have been removed without explicit deprecation.
 * The internal ResourceLoader module "mediawiki.toolbar", which is unused except by MediaWiki itself and back-compatibility code, has been removed.
 * La classe interne ResourceLoaderEditToolbarModule a été supprimée.

Obsolescences dans 1.32

 * HTMLForm::setSubmitProgressive est obsolète. Pas besoin de l'appeler. Le bouton Soumettre est déjà marqué comme progressif.
 * Skin::setupSkinUserCss est obsolète. L'ajout de modules à charger a été centralisé dans Skin::getDefaultModules, qui est maintenant capable de mettre également en file d'attente les modules de style.
 * OutputPage::addModuleScripts et ParserOutput::addModuleScripts sont obsolètes. Utilisez addModules à la place.
 * Remplacer SearchEngine::{searchText,searchTitle,searchArchiveTitle} dans l'extension des classes est obsolète. Élargissez les méthodes doSearch* associées.
 * Les modules de plug-in 'mediawiki.api' suivants ont été fusionnés dans mediawiki.api et obsolètes:mediawiki.api.category, mediawiki.api.edit, mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse, mediawiki .api.upload, mediawiki.api.user, mediawiki.api.watch, mediawiki.api.messages et mediawiki.api.rollback.
 * ApiBase::truncateArray est obsolète. Pas de remplacement, car rien n'est connu pour l'utiliser.
 * WatchAction::getUnwatchToken est obsolète. Utilisez WatchAction::getWatchToken avec le paramètre d'action 'unsatch' à la place.
 * IcuCollation::getICUVersion est obsolète, vous pouvez simplement utiliser la constante PHP INTL_ICU_VERSION directement dans toutes les versions prises en charge par MediaWiki.
 * Parser::fetchFile est obsolète. Utilisez ::fetchFileAndTitle à la place.
 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor of the namespaced classes provided by the wikimedia/xmp-reader library.
 * SearchResultSet::{next,rewind} are deprecated. Calling code should use foreach on the SearchResultSet, or the extractResults method. Extending code should override extractResults.
 * Instantiating SearchResultSet directly is deprecated. SearchEngine implementations must subclass SearchResultSet for their purposes.
 * SearchResult::setExtensionData argument has been changed from accepting an array to accepting a Closure that returns the array when called.
 * Class CryptRand, everything in MWCryptRand except generateHex and function MediaWikiServices::getCryptRand are deprecated, use random_bytes to generate cryptographically secure random byte sequences.
 * Parser::getConverterLanguage is deprecated. Use ::getTargetLanguage instead.
 * Language::markNoConversion is deprecated. It confused readers because it had unexpected behavior (only marking text if it looked like a URL) and was only used in a single place in the code.  Use LanguageConverter::markNoConversion instead.
 * (T197492) Language::truncate was soft deprecated in 1.31 and is hard deprecated in this release. It has been split into two similar methods, Language::truncateForVisual and Language::truncateForDatabase, which measure length in characters and bytes, respectively.  Use Language::truncateForVisual when possible to provide equity to users of multibyte scripts.
 * (T176526) EditPage::getContextTitle falling back to when the context title is unset is now deprecated; anything creating an EditPage instance should set the context title via ::setContextTitle.
 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 * ResourceLoaderStartUpModule::getStartupModules and ::getLegacyModules are deprecated. These concepts are obsolete and have no replacement.
 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.

 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use $formDescriptor instead.
 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior to running searchText. This method was mainly implemented to support the 'prefix' URI param in SpecialSearch, but there are no reasons to expose this logic as it should be handled internally by SearchEngine implementations supporting this feature. SearchEngine implementations should no longer override this methods.
 * SearchEngine::replacePrefixes( $query ) should no longer be called prior to running searchText/searchTitle.
 * (T199657) Messages for labels should be no longer be in the 'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.

 * The global is deprecated and nonfunctional. Set  instead.
 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev, mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded, mTextLoaded and mCacheHit is deprecated. Use getOldid / getNewid / getOldRevision / getNewRevision for the first four (note that the revision ones return a RevisionRecord, not a Revision), do your own lookup for page/content.
 * The value 'wikidiff2' is deprecated. To use wikidiff2 just enable the PHP extension, and it will be autodetected.
 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods setContent, generateContentDiffBody, generateTextDiffBody and textDiff are deprecated. To interact with a single slot, use a SlotDiffRenderer (and subclass it to customize diff rendering); to diff custom (e.g. unsaved) content, use setRevisions. Subclassing DifferenceEngine should only be done to customize page-level diff properties (such as the navigation header).
 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 * All MagicWord static methods are now deprecated. Use the MagicWordFactory methods instead.
 * PasswordFactory::init is deprecated. To get a password factory with the standard configuration, use MediaWikiServices::getPasswordFactory.

 * is deprecated, use MediaWikiServices::getParser instead.
 * wfGetMainCache is deprecated, use ObjectCache::getLocalClusterInstance instead.
 * wfGetCache est obsolète, utilisez ObjectCache::getInstance à la place.
 * All SpecialPageFactory static methods are deprecated. Instead, call the methods on a SpecialPageFactory instance, which may be obtained from MediaWikiServices.
 * mw.user.stickyRandomId was renamed to the more explicit mw.user.getPageviewToken to better capture its function.

 * Content::getSecondaryDataUpdates has been deprecated in favor of ContentHandler::getSecondaryDataUpdates for overriding by extensions (T194038). Application logic should call WikiPage::doSecondaryDataUpdates (T194037).
 * Content::getDeletionUpdates has been deprecated in favor of ContentHandler::getDeletionUpdates for overriding by extensions (T194038). Application logic should call WikiPage::doSecondaryDataUpdates (T194037).
 * (T198214) Old Tidy-related configuration settings, which were soft-deprecated in MediaWiki 1.26, have now been hard deprecated. This affects, , , , , and . Use instead.
 * All Tidy configurations other than Remex have been hard deprecated; future parsers will not emit compatible output for these configurations. In particular, running MediaWiki with tidy disabled has been deprecated.
 * (T198214) OutputPage::addWikiText, OutputPage::addWikiTextWithTitle, and OutputPage::addWikiTextTitle have been deprecated, since they can result in untidy output. In addition OutputPage::addWikiTextTidy and OutputPage::addWikiTextTitleTidy was deprecated to make naming new methods consistent.  Use OutputPage::addWikiTextAsInterface or OutputPage::addWikiTextAsContent instead, which ensures the output is tidy and clarifies whether content-language specific postprocessing should be done on the text.
 * OutputPage::parse and OutputPage::parseInline have been deprecated due to untidy output and inconsistent handling of wrapper divs and interface/content language defaults. Use OutputPage::parseAsContent, OutputPage::parseAsInterface, or OutputPage::parseInlineAsInterface as appropriate.
 * QuickTemplate::msgHtml and BaseTemplate::msgHtml have been deprecated as they promote bad practises. I18n messages should always be properly escaped.
 * Skin::getDynamicStylesheetQuery has been deprecated. It always returns action=raw&ctype=text/css which callers should use directly.
 * Class LegacyFormatter is deprecated.
 * Use of CommentStore::insertWithTempTable with 'img_description' is deprecated. Use CommentStore::insert instead.
 * Language::setCode is deprecated as public function. Use Language::factory to create a new Language object with a different language code.
 * Several classes have been moved from the MediaWiki\Storage\ namespace to the MediaWiki\Revision\ namespace. The old class names are aliased for compatibility, but are deprecated. Classes are IncompleteRevisionException, MutableRevisionRecord, MutableRevisionSlots, RevisionAccessException, RevisionArchiveRecord, RevisionFactory, RevisionLookup, RevisionRecord, RevisionSlots, RevisionStore, RevisionStoreRecord, SlotRecord, and SuppressedDataException.
 * When using OOUI HTMLForm containing an 'info' field which uses the 'rawrow' option, it is now deprecated to give its contents (the 'default' option) as a string. They should be given as a OOUI\FieldLayout object instead. Notably, this affects fields defined in the 'GetPreferences' hook, because Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
 * In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is deprecated. For the $lang parameter, types other than Language are deprecated.
 * The configuration option and the OutputPage::getKeyHeader method have been deprecated; the relevant draft IETF spec expired without becoming a standard.
 * Deprecated API action=query&prop=info inprop=readable in favor of intestactions=read.

Autres modifications en 1.32

 * (T198811) The following tables have had their UNIQUE indexes turned into proper PRIMARY KEYs for increased maintainability: interwiki, page_props, protected_titles and site_identifiers.
 * OOUI HTMLForm will now display help text inline after the input field, rather than in a popup. Previous behavior can be restored by using `'help-inline' => false`.
 * The archive table's ar_rev_id field is now unique.
 * Special:BotPasswords now requires reauthentication.
 * (T174023) Multi-Content Revision (MCR) capabilities were introduced into the storage layer and have basic support for display. No user interface exists yet for creating or managing content in slots beides the main slot. See  for more information.
 * The image_comment_temp database table has been removed. Since all access should be mediated by the CommentStore class, this change shouldn't affect external code.
 * (T206147) Database::close ne validera plus aucune transaction ouverte.

Compatibilité
MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 7.0.0 or later for long term support. MediaWiki requires that the mbstring, xml, ctype, json, iconv and fileinfo PHP extensions are loaded to work.

MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used, but support for them is somewhat less mature. There is experimental support for Oracle and Microsoft SQL Server.

Les versions prises en charge sont :
 * MySQL 5.5.8+
 * PostgreSQL 9.2+
 * SQLite 3.3.7+
 * Oracle 9.0.1+
 * Microsoft SQL Server 2005 (9.00.1399)

Mise à jour
1.32 has several database changes since 1.31, and will not work without schema updates. Note that due to changes to some very large tables like the revision table, the schema update may take quite long (minutes on a medium sized site, many hours on a large site).

N'oubliez pas de faire toujours une sauvegarde de votre base de données avant de procéder à la mise à jour !

Voir le fichier UPGRADE pour des instructions de mise à jour plus détaillées, y compris les informations importantes pour la mise à jour des versions antérieures à la 1.11.

Pour les notes concernant 1.31.x et les versions plus anciennes, voir HISTORY.
