== Upgrading notes for 1.46 ==
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 1.39.

For notes on 1.45.x and older releases, see HISTORY.

=== Configuration changes for system administrators in 1.46 ===

* $wgSVGConverter inkscape now requires Inkscape 1.0 or newer
* $wgSVGConverter presets sodipodi and imgserv were removed
* (T246054) $wgLogos['1.5x'] is no longer used. Devices that previously
displayed the 1.5x logo will use $wgLogos['1x'] instead.

==== New configuration ====

* $wgEnableWatchlistLabels - Feature flag to enable the new watchlist labels
feature (see https://www.mediawiki.org/wiki/Help:Watchlist_labels for info).
Note that the two new database tables for watchlist labels will be created
regardless of the value of this flag. Defaults to false.
* $wgUserJsPrefLimit – (T408733) This setting lets you limit the maximum number
of supported custom JS preferences each user can have, to reduce load. The
default value is 100.
* $wgBotPasswordsLimit - This setting allows administrators to configure the
maximum number of bot passwords a user can create. The default value is 100.
* $wgNamespacesWithoutAutoSummaries - (T376557) Defaults to `[]`, can be set to
a list of namespace numbers in which automatic edit summaries should
be disabled. This avoids users who have access to recent changes but no
access to a particular namespace from reading contents of limited pages
from edit summaries.

==== Changed configuration ====

* $wgSVGNativeRendering now defaults to true. This means that uploaded SVGs are
rendered directly by the browser most of the time. MediaWiki applies several
filters on uploaded SVGs to protect against malicious SVGs.
The browser adds restrictions on the SVG when included as an <img> for
additional protection. We do advise configuring CSP headers to protect users
in case they open a SVG file directly in the browser.
* $wgThumbLimits has two new entries by default, 220px and 400px. This
matches the configuration used by WMF in production. Since the default
user thumbsize option is an index into this list (currently, '5'), this
has the effect of changing the user default thumbnail size from 300px
to 250px; again matching current WMF production defaults.

==== Removed configuration ====

* (T276975) $wgAPIRequestLog, ignored since 1.43, has now been fully removed.
* $wgBlockTargetMigrationStage, ignored since 1.43, has now been fully removed.
* (T413867) $wgEnableSpecialMute and $wgEnableUserEmailMuteList feature flags
have been removed.

=== New user-facing features in 1.46 ===

* (T413375) A new parser function has been added, {{#isbn}}, which replaces
the ISBN "magic link" functionality for those wikis which have chosen to
disable it.
* (T420600) A new tag has been added called "Edited other user's JS". It is
automatically applied to edits to JavaScript pages in userspace that are not
subpages of the user making the edit.
* (T12814) Special:MovePage can now move over existing pages when moving the
talk page (following the same logic as for moving the subject page).
* (T12814) Special:MovePage will now fail loudly if you ask to move the
the talk page but it couldn't be moved (rather than not moving the
talk page and displaying an easy-to-miss error message)
* (T85393) Special:MovePage will now require explicit confirmation if the
page you are trying to move to is protected against creation.
* (T413867) Special:Mute is always unconditionally enabled.
* (T381455) Special:NamespaceInfo will now display aliases defined through
$wgNamespaceAliases.

=== New features for sysadmins in 1.46 ===

* The 'arrays' localisation cache backend is more compact: a redundant list of
message keys, and fallback data from other languages, are now deduplicated.
Old cache files should either auto-update or continue to be readable where
unchanged.
* The update.php maintenance script and the web-based schema updater now skips
messages about schema updates that were already applied in earlier MediaWiki
versions.
* A new "postprocessing" cache has been added in addition to the parser cache.
This is enabled by default for Parsoid but not for the legacy parser; use
$wgParserCacheFilterConfig to enable or disable use of this new cache.

=== New developer features in 1.46 ===

* Various functions are now marked with the #[\NoDiscard] attribute, which will
cause PHP 8.5 (and Phan) to emit warnings when their return values are not
used, as that is usually a mistake. This has no effect when running on PHP
8.4 or earlier.
* mw.message( ... ).parseDom() is now part of mediawiki.base and will return a
jQuery object wrapping a text node with the unparsed message contents if
mediawiki.jqueryMsg is not loaded.
* The LinkerMakeExternalLinkWithContext hook has been added as an improved and
slightly modernized version of the LinkerMakeExternalLink hook. Developers
are encouraged to migrate to the new hook.

=== External library changes in 1.46 ===

=== Action API changes in 1.46 ===

* In the `action=parse` API endpoint, the value `prop=sections` has been
deprecated. Use `prop=tocdata` instead (T319141). The `prop=tocdata`
schema is documented at [[mw:API:Parsing_wikitext/TOCData]].
* When specifying the Action API output format as `xml` or `xmlfm`, the
`xslt` parameter has been removed. No alternative is provided.
* (T359634) An SBOM in the CycloneDX 1.6 format can now be generated via the
`sbom` prop of meta=siteinfo.

=== Action API internal changes in 1.46 ===

* Overriding ApiBase::deprecationMsg() instead of ::isDeprecated() allows
you to provide a message describing the deprecation and recommended
replacement, which will then be visible in [[Special:ApiSandbox]] and
other human-readable descriptions of the API. Using:
$this->addDeprecation( $this->deprecationMsg(), ... );
in your ::execute() method will then ensure that a consistent message
is reported in API results as well.
See ApiQueryDeletedrevs.php for an example of this best practice.

=== Languages updated in 1.46 ===
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.

* (T407507) Updated namespace translations for Igbo (ig) language.
* (T409708) Added language support for Bole (bol).
* (T409393) Added language support for Javanese (Javanese script) (jv-java).
* (T411884) Added language support for Nawat (ppl).
* (T419373) Added language support for Lakota (lkt).
* (T423174) Added language support for East Frisian Low Saxon (frs).

=== Breaking changes in 1.46 ===

* The SpecialWatchlistGetNonRevisionTypesHook has been removed. Instead,
extensions should ensure that rc_this_oldid is set to zero on recent changes
entries that do not relate to any particular revision.
* MutableRevisionRecord::setSha1() has been removed without deprecation.
* Localizations of behavior switches must begin and end with double
underscore (`_` or U+FF3F). Some localizations present in 1.45 which
did not do so have been removed; check the category named by
[[MediaWiki::Bad-double-underscore-category]] before upgrade to see
if your local wiki contains affected wikitext.
* Passing something other than an Authority for the $performer parameter to
WatchlistManager methods clearTitleUserNotifications() and
clearAllUserNotifications, deprecated since 1.37, will now throw. User
implements Authority and so is still permitted.
* Passing something other than a PageReference for the $title parameter to
WatchlistManager::getTitleNotificationTimestamp and
clearTitleUserNotifications, deprecated since 1.37, will now throw.
* Many WatchedItemStore methods took either PageIdentity or LinkTarget, with
LinkTarget being deprecated since 1.37. Passing a LinkTarget which is not a
PageReference will now throw.
* Added an `isLegacy()` method to the `LogEntry` interface. All implementors in
core already defined this method, and the interface is not stable to
implement.
* WatchedItemQueryService::getWatchedItemsWithRecentChangeInfo, deprecated since
1.45, has been removed. The associated constants, which were used as
parameters to that method, like WatchedItemQueryService::FILTER_MINOR, have
also been removed.
* The CategoryMembershipChangeJob global namespace alias for the internal
MediaWiki\RecentChanges\CategoryMembershipChangeJob class,
deprecated since 1.44, has been removed.
* The following methods of SpecialUserRights, deprecated in 1.45, have been
removed: userCanChangeRights, expiryToTimestamp, doSaveUserGroups,
fetchUser, changeableGroups. Callers should now use the equivalent methods
from UserGroupAssignmentService or MultiFormatUserIdentityLookup.
* UserGroupsSpecialPage::canProcessExpiries (formerly
SpecialUserRights::canProcessExpiries), deprecated in 1.45, has been removed.
There's no replacement; the special page always assumes it can process
expiries.
* The tests/phpunit/phpunit.php entrypoint, deprecated in 1.41, has been
removed. Use `composer phpunit` instead.
* The tests/phpunit/suite.xml configuration file and
tests/phpunit/bootstrap.integration.php bootstrap, deprecated in 1.42, have
been removed. Use phpunit.xml.dist and bootstrap.php instead.
* The phpunit.xml.dist configuration file has been removed. MediaWiki now
provides a phpunit.xml.template file that will be used to generate a local
configuration file dependent on the wiki config. The local configuration
can be generated manually by running `composer phpunit:config`, or
automatically when running tests via `composer phpunit`.
* The tables represented by subclasses of TitleLinksTable are now expected to
be normalized to use the linktarget table. If they are not, they should
override the linksTargetNormalizationStage method to return MIGRATION_OLD.
* MimeAnalyzer::isPHPImageType, deprecated in 1.40, has been removed.
* FileRepo no longer implements getUploadStash(), only LocalRepo does.
* EtcdConfig::setLogger(), deprecated in 1.41, has been removed.
* Deprecated functions in DatabaseBlock have been removed.
- DatabaseBlock::delete(), deprecated in 1.36, has been removed. Please use
DatabaseBlockStore::deleteBlock instead.
- DatabaseBlock::update(), deprecated in 1.36, has been removed. Use the
replacement DatabaseBlockStore::updateBlock instead.
- DatabaseBlock::insert(), deprecated in 1.36, has been removed. Use the
replacement DatabaseBlockStore::insertBlock instead.
* The Result class has been removed; it was an unused alias of
Shellbox\Command\UnboxedResult since 1.36.
* The PageContentSave hook, deprecated in 1.35, has been removed.
* The MagicWordwgVariableIDs hook, deprecated in 1.35, has been removed.

* The hooks 'AbortTalkPageEmailNotification' and 'AbortEmailNotification'
(deprecated in 1.44 and 1.45) have been removed.
* The hooks 'UpdateUserMailerFormattedPageStatus' and
'SendWatchlistEmailNotification' (deprecated in 1.45) have been removed.
* The related method RecentChangeNotifier::getPageStatus() has been removed.
* Constructing SpecialRedirectWithAction without a SearchEngineFactory argument
will now trigger a PHP type error; omitting this was deprecated in 1.39.
* The PrefixSearchBackend hook, deprecated in 1.27, has been dropped.
* Parser::getDefaultSort(), deprecated in 1.38, has been removed.
* WatchedItem::getLinkTarget(), deprecated in 1.36, has been removed. Instead,
use ::getTarget() (and cast if needed).
* The AddNewAccount hook, deprecated in 1.27, has been dropped.
* wfMatchesDomainsList(), deprecated in 1.39, has been removed. Instead, use
UrlUtils::matchesDomainList().
* The PSR-7 (HTTP request/response) interfaces have been updated from the
1.1 version of the spec to 2.0, adding return type hints. The copycat
interface MediaWiki\Rest\ResponseInterface has been likewise updated.
* The global function wfAssembleUrl(), deprecated in 1.39, has been removed.
Instead, use UrlUtils::assemble().
* The global function wfArrayDiff2(), deprecated in 1.43, has been removed.
* Parser::Options(), deprecated in 1.35, has been dropped. Instead, use the
::getOptions() and ::setOptions() methods.
* DefaultSettings.php, deprecated in 1.39, has been removed.
* $wgRCEngines and remaining behaviour has been removed. This was deprecated
in 1.38.
* $wgRCFeeds now explicitly requires a class parameter. The fallback behaviour
has been deprecated since 1.38 and has been dropped.
* Various deprecated Parser class functions have been dropped.
- Parser::OutputType(), deprecated in 1.35. Use ::getOutputType() and
::setOutputType() instead.
- Parser::getFunctionLang(), deprecated in 1.40. Use ::getTargetLanguage().
- Parser::doBlockLevels(), deprecated in 1.35. Internal-only replacement
is provided by BlockLevelPass::doBlockLevels().
- Parser::attributeStripCallback(), deprecated with warnings in 1.35.
This was never intended to be public.
- Parser::enableOOUI(), deprecated with warnings in 1.35. Use
$parser->getOutput()->setEnableOOUI() instead.
- Parser::getPage() never returns null. Calling ::getPage() without
a title set was deprecated in 1.34 and has emitted warnings when
returning null since 1.41.
- Parser::getOutput() never returns null. Calling ::getOutput() before
the initialization of ParserOutput has been deprecated with warnings
since 1.43.
- Parser::setCacheTime() no longer accepts -1 to mean "not cacheable".
This has emitted deprecation warnings since 1.36.
* ContentSerializationException no longer extends deprecated MWException.
* ContentHandler::checkFormat() and AbstractContent::checkFormat() now
throw UnsupportedContentFormatException instead of deprecated MWException.
* wfMergeErrorArrays(), deprecated in 1.43, has been dropped.
* Article::getRedirectHeaderHtml(), deprecated in 1.41, has been dropped.
Instead, use LinkRenderer::makeRedirectHeader().

instead of Status. There are no known callers outside of core.
* Various deprecated global functions for handling URLs have been dropped.
- wfParseUrl(), deprecated in 1.39, has been dropped. Instead, use
UrlUtils::parse().
- wfExpandUrl(), deprecated in 1.39, has been dropped. Instead, use
UrlUtils::expand().
- wfUrlProtocolsWithoutProtRel(), deprecated in 1.39, has been dropped.
Instead, use UrlUtils::validAbsoluteProtocols().
- wfUrlProtocols(), deprecated in 1.39, has been dropped. Instead,
use UrlUtils::validProtocols().
* The 'vform' HTMLForm display format, deprecated in 1.45, has been removed.
Use the 'codex' display format introduced in 1.41, or the 'ooui' format
if you need form fields that are not supported by Codex yet.
* The VFormHTMLForm class and the HTMLFormField::getVForm() method
have been removed.
* ContentHandler::checkModelID() and AbstractContent::checkModelID() now
throw UnexpectedContentModelException instead of deprecated MWException.
* The mediawiki.ui module, deprecated in 1.41 and unused, was removed.
Instead, use Codex modules.
* The mediawiki.ui.input module, deprecated in 1.41 and unused, was removed.
Instead, use Codex modules.
* The mediawiki.ui.checkbox module, deprecated in 1.41 and unused, was removed.

=== Deprecations in 1.46 ===

* (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.

In this release of MediaWiki, 2987 classes now have a namespace and 26 do
not yet (99% done, up from 89% in MediaWiki 1.45.0). The following have newly
