Mapster 2.0 Released!

We’ve released Mapster 2.0, and it’s looking really good!  This definitely puts Mapster back on top as the best, most complete, fast .Net mapper out there.  If you need something that won’t get bogged down under heavy load but has very rich features, this one’s for you.

Huge shout to Chaowlert, who took this project and ran with it, adding all of the new updates and optimizations.
