The major new addition is the Preflight action enabling checks in the task sequence to help prevent the task sequence from proceeding based on the current state of the system. Info fields on the Input action, group membership detection for an authenticated user, a few additional detections, and few UI tweaks are also included.
For full details and to download the latest version, see the UI++ page.
Note that I temporarily removed the inclusion and exclusion functionality from the AppTree action. The code, as was, had too many unaccounted for fringe scenarios that caused all kinds of weird behavior. I’ll be working hard to bring it back though very soon.
