We have been waiting a while with even considering upgrading 2.0, since we read for example here and here that the number of unknown bugs in new beta versions were with 2.0 much higher then normal. There were even downgrade tools from 2.0 to 1.5 ! Especially many of the old plugins where not competible (which is a pain) .
So.. with the release of 2.01, is now the time to upgrade ? We think the wiki meta integration is a must, looking at the bugreport now and further plans, I think it’s time.
Ps. did you know about the WordPress Maps [here, here and here (incl. competitors)] or the relation between 1.5 Strayhorn and 2.0 Duke?
update: another one.
I am still having some problems / bugs on a few of my websites. So I will wait a while before I upgrade this website.
Some mayor bugs:
htaccess not working in 2.01 !!

Can’t Upload Files/Images

It seems that this bug is a overule conflict on some servers on others it just works fine.
