The latest release of WordPress has just come out (2.0.3 – I’m on 2.0.2 at the moment) so hold tight and think happy thoughts. I might need them. What’s the worst that could happen?
Update – Much to my disappointment it was a very easy upgrade. These WordPress people know what they’re on about!
My fire alarm went off during my upgrade… but (also to my disappointment) it was unrelated.
