= 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 1.36.x and older releases, see HISTORY. === Configuration changes for system administrators in 1.38 === * Deprecate $wgAjaxUploadDestCheck, act as always-true * … ==== 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. * $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. * … ==== 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. * … === New user-facing features in 1.38 === * … === New developer features in 1.38 === * 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'. * … === External library changes in 1.38 === ==== New external libraries ==== * symfony/yaml was promoted from development-only. * … ===== New development-only external libraries ===== * … ==== Changed external libraries ==== * Updated guzzlehttp/guzzle from 7.2.0 to 7.4.0. * Updated OOUI from v0.42.0 to v0.42.1 * Updated WVUI from v0.3.0 to v0.3.4 * Upgraded Vue from 2.6.11 to 3.2.23 * 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 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/minify from 2.2.4 to 2.2.6. * Updated wikimedia/wrappedstring from 3.2.0 to 4.0.1. * Updated composer/semver from 3.2.5 to 3.2.6. * … ===== Changed development-only external libraries ===== * Updated doctrine/dbal for PHP < 7.3 from 2.10.4 to 2.13.4. * Updated doctrine/dbal for PHP >= 7.3 from 3.0.0 to 3.1.3. * Updated composer/spdx-licenses from 1.5.4 to 1.5.5. * Updated composer/semver from 3.5.4 to 3.5.5. * … ==== 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).
