Any astute visitors to my website will have noticed a few changes today. And for those who didn't I don't really blame you, they aren't that obvious. First off, I've upgraded my site to be running Umbraco 4 RC 1. It's been out for a while so I thought it was time I joined the hip crowd and started running it. I have been using it since Beta 2 on another site, but now I have my own running it as well.
