I’m upgrading to a new version of WordPress. If you see any errors or the page is rendering weird, that it is why.

[Update]
Although there was one minor hang up, the upgrade went relatively smoothly. It also meant that I went through and got the latest updates to my plugins, which is a major plus. This was a good, solid update. The WordPress team has done a really good job of making upgrades practically painless. I should have upgraded a long time ago.
