Here's a list that I've been putting together through the whole beta/rc cycle for the various bits for Microsoft Office Sharepoint Server(or Windows Sharepoint Services V3)
Note: Individual components have progressed in their own realm but until the next release of Office 2007 BXXX (or RC 1), then these are the compatible respective components.In the end - all the products and components will be aligned with each other's current version. Until then we have to crawl along a little at a time. Try doing 14 months of this.....
Time to get cracking......:)
