The last known critical bugs in the jQuery UI version have been fixed and we plan to roll out to the stable channel in the coming days.
If you have a chance please check out the dev channel by switching release channels from your account. It would help to have as many eyes as possible looking at this in case anything critical is missed.
If you encounter any issues please either report them to the list or the github issue tracker.
I've added a legacy channel for those that prefer to stay on the ExtJs version. There shouldn't be any reason to stay on that version but it's there just in case. Eventually the Extjs version will be phased out if there are no serious objections.
