For these updates that were just released, the most important piece seems to be the Webapp security update. For those of us running 19.1 and not using the Webapp, is there any reason to update? i.e. were any other Windoze related bug fixes included in this update? If I update my 19.1 Studio and one of my customers doesn't update their 19.1 runtime, then I have a mismatch for that customer which I think has been stated isn't recommended.

Clarification?
