Hello and Happy New Year (I was being away for a while).
Hmm, do you have any changelog yet? I installed over my previous installation, and it denied my free license (I had 3 months before it expires). After a couple of times trying to downgrade back to the free version it said "something went wrong, please retry bla-bla". I had to use one of the public free keys to downgrade, but now only 1 device is protected with it. With my previous free key, they were 3 devices and I added my Android phone to it as well. At least, the license now is for another 365 days.
But the most strange thing I've noticed is that despite I am using the Free version I have Firewall and Intrusion Prevention. How is that possible? I doubt they added them to the free version. Probably the program still think I am using the Standard version instead?
At least the Firefox add-on is green again instead of gray.
