= MediaWiki 1.43 =
== MediaWiki 1.43.0-PRERELEASE ==
THIS IS NOT A RELEASE YET
MediaWiki 1.43 is an alpha-quality development branch, and is not recommended
for use in production.
== Upgrading notes for 1.43 ==
Don't forget to always back up your database before upgrading!
See the file UPGRADE for more detailed per-version upgrade instructions from the
oldest supported upgrading version, MediaWiki 1.35.
Some specific notes for MediaWiki 1.43 upgrades are below:
* It is now necessary that the OpenSSL PHP extension is installed.
* …
For notes on 1.42.x and older releases, see HISTORY.
=== Configuration changes for system administrators in 1.43 ===
* $wgBlockTargetMigrationStage, which was introduced in 1.42, is now deprecated
and has no effect.
* …
==== New configuration ====
* (T13555) $wgParserEnableLegacyHeadingDOM - Defaults to `true`, can be set to
`false` to enable new, more accessible HTML markup for wikitext headings.
Note that each skin must also use the 'supportsMwHeading' option to allow it.
More information: https://www.mediawiki.org/wiki/Heading_HTML_changes
In a future release the new markup will become the default,
and later this option will be removed.
* (T12347) $wgEnableProtectionIndicators - Defaults to false, setting it to true
shows a lock icon indicator on protected pages.
* (T373480) $wgSortedCategories - Defaults to false, setting it to true will
sort the categories shown on article pages. This is an experimental setting;
its future will depend on community adoption and feedback on the phab task
is welcome.
* (T45646) $wgAllowRawHtmlCopyrightMessages - Defaults to true, can be set to
false to disable the use of the localisation messages 'copyright' and
'history_copyright' and the hook 'SkinCopyrightFooter', which have been
deprecated in this release. This helps protect your wiki against attacks by
a rogue administrator account and will become the default in the future.
* …
==== Changed configuration ====
* wgPageLinksSchemaMigrationStage – (T299947) This temporary setting, which
controls the database schema migration for the page links table, is now set
by default to write to both old and new data and read from the new data.
* wgFooterIcons – (T256190) The default "Powered by MediaWiki" button icon has
been updated to an SVG icon, and the footer icons are now wrapped as buttons
in HTML, rather than faking it within the icons themselves. You should adjust
any footer icons you provide or over-ride to match.
* The "error-json" channel, configurable via $wgDebugLogGroups, has been
removed. For structured logging, use the "error" channel directly instead.
Since MediaWiki 1.25, structured logging is supported via Monolog for all
channels, including the "error" channel. For silenced errors, you use the
"silenced-error" channel added in MediaWiki 1.42. (T193472)
* wgResourceLoaderUseObjectCacheForDeps - (T343492) This is now enabled by
default. This means ResourceLoader writes information to the MainStash
instead of a core database table, which can be set to a separate database
via wgMainStash. If you find issues, please drop a comment on T343492.
It is now deprecated and will be removed in MediaWiki 1.44.
* …
==== Removed configuration ====
* wgSessionInsecureSecrets has been removed since OpenSSL is now a required
PHP extension.
* $wgTemplateLinksSchemaMigrationStage has been removed.
* $wgSamplingStatsdClient has been removed. It was introduced in MW 1.28 for
use in the Wikibase extension, but never used. The new StatsFactory service
should be used for new instrumentations, which already supports sampling.
Beware that sampling is generally not needed even at scale, and that sampling
does not significantly reduce runtime overhead, thus making it slow to
instrument very hot code even with built-in sampling.
* (T294397) The 'writeapi' userright, which controlled access to some API
modules, has been removed.
* …
=== New user-facing features in 1.43 ===
* (T338341) Support reading XMP and EXIF from WebP files
* (T365636) Wiki's with wgAllowExternalImages enabled now detect urls
with AVIF, SVG and WebP images.
* (T242346) Special:TalkPage is a new special page that will redirect to the
associated talk namespace page, e.g. [[Special:TalkPage/Foo]] redirects to
[[Talk:Foo]]; [[Special:TalkPage/Project:Foo]] goes to [[Project talk:Foo]].
This allows for links by templates and tools without having to parse what
namespaces are valid and have associated talk pages.
* New preference: "Send password reset emails only when both email address
and username are provided."
* (T4085) Added new magic word {{USERLANGUAGE}} which returns the language code
of the interface set by the user.
* …
=== New features for sysadmins in 1.43 ===
* …
=== New developer features in 1.43 ===
* StatusValue class gained new method getMessages(): MessageSpecifier[],
allowing the errors to be inspected and displayed more easily, for example:
foreach ( $status->getMessages() as $msg ) {
if ( $msg->getKey() !== 'ignored-message' ) {
$this->getOutput()->addWikiMsg( $msg );
}
}
* The REST API framework now supports defining redirects in route definition
files. See MediaWiki\Rest\Handler\RedirectHandler for details.
* (T13555) Skins can enable the 'supportsMwHeading' option for new, more
accessible HTML markup for wikitext headings. MediaWiki's own styles and
scripts have been updated to support it, but your skin may also need updates.
More information: https://www.mediawiki.org/wiki/Heading_HTML_changes
A future release will emit deprecation warnings for skins with
'supportsMwHeading' set to false.
* The AuthPreserveQueryParams hook was added.
* (T219397) New `Language::formatDurationBetweenTimestamps()` function added
which takes two timestamps and a precision in order to calculate a more
accurate text representation of duration.
* Added an interactive mode to the install.php maintenance script.
* The ResourceLoaderModifyEmbeddedSourceUrls hook was added.
* The AuthManagerFilterProviders hook was added.
* The AuthManagerVerifyAuthentication hook was added.
* The OutputPageRenderCategoryLink hook was added, as a replacement for the
deprecated OutputPageMakeCategoryLinks hook.
* PreAuthenticationProvider, PrimaryAuthenticationProvider, and
SecondaryAuthenticationProvider now receive a `canAlwaysAutocreate` flag in
the options of the `testUserForCreation` invocation. This flag is true when
the session provider is exempt from autocreate user permissions checks.
* The CentralIdLookup service gained the isOwned() method, which can be used
to check if a local username is reserved for a central user, even if a local
user account does not exist yet. This can be used by extensions to look
up information about the central user.
* (T251790) A Jest-based test suite has been introduced for testing front-end
code such as Vue components. Tests can be run via `npm run jest`, and test
files live in `tests/jest/`. See https://www.mediawiki.org/wiki/Jest
for more information.
* The SpreadAnyEditBlock hook was added.
* The ConditionalDefaultOptionsAddCondition hook was added.
* …
=== External library changes in 1.43 ===
* The OOjs Router library has been merged into core and will be archived
upstream.
==== New external libraries ====
* …
===== New development-only external libraries =====
* (T251790) Some development-only external libraries have been added for the new
testing tools for front-end Vue components:
* Added jest and jest-environment-jsdom at v29.7.0.
* Added @vue/test-utils v2.4.6.
* Added @vue/vue3-jest v29.2.6.
* Added @babel/preset-env v7.25.4.
* Added pinia v2.0.16 (already available via ResourceLoader).
* Added @pinia/testing v0.0.12.
* Codex, already available via ResourceLoader, now has the npm versions, i.e.
@wikimedia/codex and @wikimedia/codex-icons, also installed for testing.
* …
==== Changed external libraries ====

* Overriding MWException::getHTML(), ::getText(), ::getPageTitle(), and

longer supported.
* In PageHandlerTestTrait, the newRouter() method was renamed to
newRouterForPageHandler() to avoid a conflict with a method of the same
name in RestTestTrait. Also, PageHandlerTestTrait is no longer marked as
"stable to use". It was marked this way by accident, the functionality it
provides is specific to certain handlers implemented in MediaWiki core.
* MediaWikiIntegrationTestCase::addCoreDBData(), deprecated since 1.41, has
been removed.

hooks are: ContribsPager__reallyDoQueryHook, ContribsPager__getQueryInfoHook,
ContributionsLineEndingHook, SpecialContributions__formatRow__flagsHook.
* Hooks that were run from DeletedContribsPager are now run from the parent,
ContributionsPager. If a pager is passed in, it is a ContributionsPager type,
and documentation and type comparisons may need to be updated. Affected
hooks are: DeletedContribsPager__reallyDoQueryHook and
DeletedContributionsLineEndingHook.
* The public method ContributionsSpecialPage::getUserLinks has been made
protected. Although not marked @internal, the method was public to be called
from SpecialDeletedContributions (call now removed), and was not called from

Linker::tocUnindent(), Linker::tocLine(), Linker::tocLineEnd(), and
Linker::tocList(), deprecated in 1.42, have been removed.
* Linker::formatComment(), Linker::formatLinksInComment(),
Linker::commentBlock(), and Linker::revComment(), deprecated in 1.38,

It existed for internal use by SqlBagOStuff only.
* Support for WinCache as local server cache has been removed, because WinCache
is not available for supported versions of PHP. The WinCacheBagOStuff class
has been removed. Use MediaWikiServices::getLocalServerObjectCache() instead,
or the CACHE_ACCEL type instead, which automatically selects APCu when
available.
The "wincache" cache type (e.g. to ObjectCache::getInstance, and in
"wg*CacheType" configuration) remains supported as an alias for CACHE_ACCEL.
* LockManager::sha1Base16Absolute(), has been removed without deprecation.
* The "options" parameter to User::createNew() and the $data parameter to

* The setStats() method in MediaWiki\Rest\Router now expects a StatsFactory
rather than a StatsdDataFactoryInterface. The method has been marked @internal
and should not be called by extensions.
* All `@width-breakpoint-*` Less variables have been removed. Use
`@min-width-breakpoint-*`/`@max-width-breakpoint-*` instead.
* The MessageContent class, deprecated since 1.38, is now removed. This also

manually sourcing SQL files, but if you are doing this, run
`update.php --initial` instead of sourcing update-keys.sql.
* MediaWikiVersionFetcher, deprecated since 1.42 has been removed.
* …
=== Deprecations in 1.43 ===
* The methods StatusValue::getErrors() and StatusValue::getErrorsByType(),
as well as Status::getErrorsArray() and Status::getWarningsArray(), have
been deprecated in favor of new method StatusValue::getMessages().
* PermissionManager::getPermissionErrors() has been deprecated in favor
of getPermissionStatus().
* PermissionStatus::toLegacyErrorArray() is deprecated with no replacement.
* PermissionsError properties $errors and $permission are deprecated.
To display the error, throw it or use ->report().
* (T166010) All PHP code in MediaWiki is slowly being moved to be in a class
namespace as appropriate, so that we can use PSR-4 auto-loading, which will
speed up general code loading of MediaWiki. The old global namespace class
names are being left behind as deprecated aliases.
