Service Pack 4 for Dynamics GP 9.0 is out! Looks like this is the last Service Pack for GP 9.0. On one hand I find that a little strange since GP 9.0 will be supported until 2011. On the other hand, GP 9.0 is very stable and I really don’t hear of too many things that need fixing.
The complete list of all GP 9.0 service packs will have some additional information on versions, etc.
