Upgraded from WP 2.1 to WP 2.1.2
Dreamhost made it pretty easy to upgrade. Push the button. Wait a while. Tada. :-)
At first blush, it looks like performance is much improved :-))
Update: Ah. Performance increased because Dreamhost automatically upgraded my WP-Cache from 2.0 to 2.1. It appears that WP 2.1 wasn’t compatible with WP-Cache 2.0. All is speedy now.
Update. It was to 2.1.1… now it’s 2.1.2
