The main feature left to implement are autoupdate for which the code is already there and all I need to do is find time to test against the GotDotNet server before it goes public. Actually that's not true, there's also the issue of how to handle rolling back bad updates.

Another feature which I'd also like to see us get to before providing an official v1.1 release is support for a plugin architecture which at the minimium should include Simon Fell's BlogThis proposal.
