A minor release, but looks like some major improvements, such as a new SQL Server 2005 provider that takes advantage of some new features for better performance.

I've plugged Paul Wilson's O/R Mapper before, but I don't think it would hurt to reiterate that it is a fantastic tool.  I strongly encourage you to take it for a real test run (read: complete a small but real-world application with it).  Reading the feature list and taking it for a quick spin just won't do it justice.  If you've not used an O/R mapper before, it takes a little time to adopt the right mindset.  However, I think the benefits will become very clear once you see what it is capable of.  The beauty of WilsonORMapper is in its simplicity. 

I also recommend you try Paul Welter's CodeSmith templates for WilsonORMapper.  You can point CodeSmith at your database and generate a complete set of business classes ready to handle just about everything you need to do.  I have not yet tried the new CodeSmith templates from Jason Bunting.

Full list of changes can be found on Paul's blog.
