Downloaded new GUI Wallet, it's looking fine, but in the about column I see: Sia UI version: 0.4.0, Sia version: 0.4.0
Yeah we forgot to bump the version numbers. We'll fix it tomorrow (we're taking it easy today - long week).
OK, it's not a big issue, but I didn't set any password to my wallet, now it's locked, and I have no idea which password to enter.
