Changes between Version 7 and Version 9 of Ticket #31436

v7	v9
9	9	For the previously-reported issue specific for handling conflicts between editing widgets on the widget admin page, see #12722.
10	10
	11	For the introduction of concurrency locking for options pages (settings API), see #32202.
	12
11	13	Some enhancements for a feature plugin: The Customizer UI would benefit from having a list of users currently in the Customizer appearing somewhere, with a list of the changes each user has made. If someone left their Customizer session open, this list would also allow an administrator to sign the user out, using something like the [https://wordpress.org/plugins/user-session-control/ User Session Control] plugin; or the Customizer UI could provide a way to boot a user from the Customizer.
