I’ve taken the plunge. For one its speedy. Secondly it includes the widgets plug-in which is nice (although I was already using it). The biggest difference I can see is the speed improvement. However this was the first opportunity I had to test my new DEV server procedure. I’ve had WordPress 2.2 on http://dev.aldrichfamily.org since about 5 minutes after it was released. I’ve played around a little bit, made sure all the plug-ins I want to use still work. After I was sure I had a database backup of the current install (via the daily scheduled backups now) I decided it was time to take the plunge. Probably the easiest upgrade thus far.
