Subject says most of it
I have looked around the site but have come up empty. Does it matter?
I ask because I had a nagging, repeated issue where version 5 constantly deleted cookies I require for my bank which forced me to re-authenticate myself and my computer to my bank over and over. I have downloaded the latest beta for version 5 but have yet to run it.
Fwiw, version 4 still seems to run like the champ it has always been so perhaps that is an argument to not even bother with version 5.
