Just wanted to let folks know that we actually released Unity 1.1 last Friday, along with Entlib 4. Then folks promptly went on vacation and we forgot to update the codeplex site. Sorry!
A new release has been added
to the release pages here. It's primarily bug fixes; the only new feature is much better error message when resolving an object fails. In addition, we've improved the performance when resolving singleton objects quite a bit.
