MediaWiki has been updated to 1.39 at FS Wiki

MediaWiki™ is the software which runs all of the wiki components on Fandom communities. Respecting our commitment to keep MediaWiki up to date on a regular basis after the implementation of the Unified Community Platform, we are running at least one major update every year. Those major updates are updating not only the MediaWiki version, also the extensions and functionalities used in the whole platform. The previous major update done in Fandom was the update to MediaWiki 1.37.

Changelog in MediaWiki 1.39[]

Important notes for admins[]

CSS customizations should work as previously in 1.37. This upgrade hasn't introduced relevant changes in this area and our engineers have applied changes on their own to avoid moving this work to the admins.

Security[]

SECURITY: HTMLUserTextField exposes existence of hidden users.
SECURITY: On action=rollback the message "alreadyrolled" can leak revision deleted user name.
SECURITY: ApiEditPage update title after redirects.

Articles and editing[]

Validate length of user email on Special:ChangeEmail/Special:CreateAccount.
Repair language selector for SVGs.
The auto-number headings feature was removed following a consultation due to performace reasons.
New deletetalk parameter on action=delete that allows you to delete the associated talk page of a subject page.
Similarly, new undeletetalk parameter on action=undelete that allows you to restore all revisions of the associated talk page.
The character > is included in the list of invalid username characters. It's a reserved delimiter for external user names.
Administrators now have the option to delete/undelete the associated Talk page when they are (un)deleting a given page. deletetalk and undeletetalk options were added to the delete and undelete actions APIs.
{{=}} is now a wikitext built-in magic word, expanding to =. This is conventionally used as an escape mechanism to allow the use of = in unnamed template arguments. Defining Template:= to expand to something other than = has been deprecated since 1.36, with affected pages put into a special tracking category for migration.
Bot passwords are now supported when using the REST API.
Usage of var() CSS function in inline styles has been re-enabled.

External libraries[]

Upgrade jQuery from 3.6.0 to 3.6.1.
Removed jquery.jStorage, deprecated since MW 1.28; use mediawiki.storage instead.
