Some of you may be wondering about the status of Caliburn.  I'm presently working on the new version and am having great success making it compatible with both WPF and Silverlight.  It hasn't been easy, but it is going to work.  There's a lot of under-the-hood improvements in this new version and I think it's going to be great.  That said, even though I have decided to focus only on "Actions" for this first version, there is a lot of work that it takes to truly get it done right, and to provide decent test coverage.  My company has been busy lately doing some neat projects, including working with this ninja and also helping this company build some ground-breaking GIS goodness.  As a result, I've had to spend a little less time on Caliburn.  In spite of the slight loss of time, things are progressing well and I hope to commit the new code in about a month or so.  Thanks for your patience!
