I’ve upgraded and if you are seeing this, then the process was the normal easy, couple of clicks upgrade. So far the interface looks cleaner and I’m liking the fact that finally the updates is at the top of the main dashboard menu rather than being buried in a couple of menus and not in the obvious place. It was weird that plugin upgrades were not under the upgrade option in 2.9.2
Let me know if anything isn’t working – I’ll be upgrading the other sites in the next couple of days – it will be interesting to see what is discussed at Wordcamp/Podcamp Ohio on Saturday.
