Well... I made the transition from 5.0.6 to 5.0.8 yesterday on our server. I'm very happy about the stability, bug fixing that has been done, speed has been increased and it's a very good thing.
On the other hand, I'm kind of worried about all the Yahoo marketing crap that's floating around now. I've paid for the license, the accounts, the archive feature... I don't think I need to have Yahoo flagged everywhere in my webclient, it feels almost like ads or advertising and users here are not very happy with it.
When you switch to one of the themes, it's even writen "Yahoo Mail" ? WTF ?
I know Zimbra is owned by Yahoo, but until Zimbra changes it's name, I want zimbra on it and not Yahoo thingy. Smileys already made the way on this release I see. I'm kind of worried.
