= MediaWiki 1.38 = == MediaWiki 1.38.0-PRERELEASE == THIS IS NOT A RELEASE YET MediaWiki 1.38 is an alpha-quality development branch, and is not recommended for use in production. == Upgrading notes for 1.38 == 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 1.29. Some specific notes for MediaWiki 1.38 upgrades are below: * … For notes on 1.37.x and older releases, see HISTORY. === Configuration changes for system administrators in 1.38 === * Deprecate $wgAjaxUploadDestCheck, act as always-true * $wgInterwikiCache no longer supports the string value for CDB files. * … ==== New configuration ==== * $wgBrowserFormatDetection – This setting allows overriding browsers' automatic detection and handling of formats. It's initially used to prevent auto-linking of possible telephone numbers in wiki pages' output in Safari on iOS; this can be re-enabled if you wish, or locally extended for other browsers' quirks. * (T240685) $wgMetricsTarget, $wgMetricsFormat, $wgMetricsPrefix - Configuration for a new MetricsFactory service with support for the dogstatsd format, intended for integration with Prometheus integration. * $wgGroupInheritsPermissions – This setting allows inheriting permissions, both granted and revoked, from another group. * $wgForeignApiRepos – ForeignAPIRepo now has a apiMetadataExpiry option to control how long file metadata is cached. Additionally the default changed from 1 hour to 4 hours. * $wgSkinsPreferred – List of preferred skins to be listed higher in Special:Preferences * $wgEnableRemoteBagOStuffTests replaces the environment variable PHPUNIT_USE_BAGOSTUFF. * (T230211) $wgForceDeferredUpdatesPreSend – Force deferred updates to be run before sending a response to the client, instead of attempting to run them after sending the response. Setting this to true is useful for end-to-end testing, to ensure that the effects of a request are visible to any subsequent requests, even if they are made immediately after the first one. Note however that this does not ensure that database replication is complete, nor does it execute any jobs enqueued for later. * … ==== Changed configuration ==== * $wgMaxImageArea - This setting may now be set to false to disable size checking before scaling. Extensions can still override its value by using the BitmapHandlerCheckImageArea hook. * … ==== Removed configuration ==== * $wgShellLocale - This setting has been removed as it was a flawed solution to the problem of locale dependence, MediaWiki will now always set a locale of C.UTF-8 or C and works around the remaining problems of the C locale by not using escapeshellarg. This follows the direction of PHP 8.0, which sets a locale of C by default instead of respecting LC_CTYPE. * $wgLoggedOutMaxAge - Experiment removed, originally added in 1.35. (T293848) * $wgIncludejQueryMigrate - Deprecated in 1.36. We only support jQuery v3. * $wgUseCategoryBrowser - This experimental feature has been removed. If you still need to use this feature, please see [[mw:Extension:CategoryExplorer]]. * … === New user-facing features in 1.38 === * … === New operator/developer features in 1.38 === * EXPERIMENTAL: The environment variable MW_CONFIG_FILE can be used to specify the location of the settings file. This allows alternative settings files to be loaded depending on the environment. Settings files may be given as PHP files like the traditional LocalSettings.php file, or they may use JSON or YAML format. See https://www.mediawiki.org/wiki/Manual:YAML_settings_file_format * Added a deleteUserEmail maintenance script - This file enables the deletion of a given user's associated email address. It can be helpful for privacy-preserving operations. * Description array for constructing HTMLForm now can use 'disable-if' to disable fields on condition easily, supported expressions are the same as 'hide-if'. * New interface IForeignRepoWithMWApi. This allows you to mark extension file repos as supporting making API queries against the foreign file repo so that extensions like TimedMediaHandler that depend on this can stop hardcoding looking for specific class names. * Running QUnit tests for an individual test suite module is possible with `grunt qunit --qunit-component={componentName}`, where {componentName} is "MediaWiki" to run core's QUnit tests or the skin or extension name. * … === External library changes in 1.38 === ==== New external libraries ==== * symfony/yaml was promoted from development-only. * Added Codex v0.1.0-alpha.3 * … ===== New development-only external libraries ===== * … ==== Changed external libraries ==== * Updated OOUI from v0.42.0 to v0.43.1. * Updated WVUI from v0.3.0 to v0.3.5 * Upgraded Vue from 2.6.11 to 3.2.23 * Updated composer/semver from 3.2.5 to 3.2.6. * Updated guzzlehttp/guzzle from 7.2.0 to 7.4.1. * Updated pear/mail_mime from 1.10.9 to 1.10.11. * Updated pear/net_smtp from 1.9.2 to 1.10.0. * Updated psr/log from 1.1.3 to 1.1.4. * Updated wikimedia/assert from 0.5.0 to 0.5.1. * Updated wikimedia/cdb from 1.4.1 to 2.0.0. * Updated wikimedia/minify from 2.2.4 to 2.2.6. * Updated wikimedia/parsoid from v0.14.0-a14 to v0.15.0-a1. * Updated wikimedia/purtle from 1.0.7 to 1.0.8. * Updated wikimedia/shellbox from 2.0.0 to 3.0.0. * Updated wikimedia/wrappedstring from 3.2.0 to 4.0.1. * Updated psy/psysh from 0.10.5 to 0.11.1. * Updated symfony/polyfill-php80 from 1.23.1 to 1.24.0. * Updated wikimedia/ip-utils from 3.0.2 to 4.0.0. * Updated wikimedia/request-timeout from 1.1.0 to 1.2.0. * … ===== Changed development-only external libraries ===== * Updated composer/semver from 3.5.4 to 3.5.5. * Updated composer/spdx-licenses from 1.5.4 to 1.5.5. * Updated doctrine/dbal for PHP < 7.3 from 2.10.4 to 2.13.6. * Updated doctrine/dbal for PHP >= 7.3 from 3.0.0 to 3.1.5. * … ==== Removed external libraries ==== * jquery.jStorage, deprecated since MW 1.28; use "mediawiki.storage" instead. * … === Bug fixes in 1.38 === * … === Action API changes in 1.38 === * New `variant` parameter for all API actions, for specifying language variant (akin to the existing `variant` parameter for index.php).
