After one day with the newest release:

It's nice to finally be able to re-size the font for the interface - I ended up not changing it because I've gotten so used to it, but it's nice to have the option for days when my poor old eyes don't feel like working so hard.

It seems to start much faster: from clicking on the icon to being able to start working is about 5-6 seconds now, before it was 20-30 seconds on my system.

I lost all my smart content due to the change in the content management system from Valentina to PostGres (until I can figure out how to reimport it) but I didn't really use that feature much.

That's about it - I haven't noticed any other changes since I never ran into any of the issues that were fixed.
