Tough to say...so far seems as stable as the official 386 release and internal/external network speeds are more or less the same. All of my settings from the official 386 release carried over into the newest beta just fine. Although I'm guessing here, I think the UI hang-up is caused by my somewhat lengthy manual DHCP assignment list. That's the only factor I saw trigger the issue back in the RC2-10 beta firmware.
Then what are the advantages from the released firmware? Security fixes?
