Given the strong integrations between Dynamics GP and Microsoft CRM, I thought that I would mention that CRM 4.0 was released to manufacturing on December 14th. That and I like acronyms and this title had plenty of them!
It will be a few more weeks before the download bits are available and the launch parties will start in March. Various versions (Pro, Enterprise, etc.) will dribble out over the next six months. You can hit up Ben Volmer's site for more CRM stuff.
