(Windows 10 pro, Finale 25)
Having made the upgrade, I am disappointed to find that one old problem remains, and others may have appeared.
I tried to renumber my bars using "Edit Measure Number Regions" and was unable to do so reliably. Regions appeared to be numbered almost at random. Eventually I used the Patterson utilities, and was successful.
It seems not to be possible to distribute bars on pages when in page view after defining measure number reasons other than the default. This was also a problem with Finale 2014, all versions.
I also notice that, whenever I use Finale, my keyboard switches to a US layout. I live in the UK and work with a UK layout, so this is a pain!
It is probably a "feature" of my monitor setup, but the cursor disappears off the edge of the screen when using 75% zoom.
