A couple of things I have noticed.
1. No speaking of "alt-tab" between screens.
2. Automatic speaking of auto-completed addresses in Internet Explorer.
3. The settings transfer from JFW 2018 included not only settings but third-party scripts for my out-dated email client. Hur raw!
4. When in an edit field including more than one line, JFW now says 'multi-line",.
So far it is very stable and wonderfully cooperative.
