Comments or guidance appreciated.
If you want to see if the newest version offers some new functionality you would find useful, a zero-risk situation would be installing the PORTABLE version of the latest in its own folder, and playing around with it to your heart's content, deleting it if the answer is "no."
Like frankz I apply every patch as soon as they come out and never had to back out of anything yet. I do keep a recent backup (again, portable) in easy reach in case I get too exuberant trying new layouts and paint myself into a corner!
