I upgraded to Wordpress 2.2 today. It does’t really seem like there are a lot of new user-visible features, but they are really starting to make more regular releases, so we should see more gradual improvements.

One of the good features is better support for the One True Syndication Format Atom. Atom support was a bit rough in previous versions, so you could only do post feeds and not comment feeds by default. They’re also supporting the Atom 1.0 spec now which is the latest and greatest.

On the Admin side they’ve integrated Widgets for managing sidebar content. I haven’t played with it much, but it’s full of Ajaxy drag-n-drop goodness.
