In a few weeks, Sage will announce a New Plan that will allow customers that have very old MAS products to get caught up to the 3.7x version of the both Sage MAS 90 and Sage MAS 200.   The plan is called Sage Software MAS 90 and 200 3.x Value Plan.

The key development is that the retirement schedule of version 3.7x is now going to get extended to past 12/31/2008 as Sage states in the comment below:

"It is important to note that this new 3.x value plan will not include support for the Microsoft Vista operating system nor the MAS 200 SQL platform. As a result of this new plan, version 3.71 retirement will be extended past the previously announced target of 12/31/2008. The new target date will be communicated at a later date. Customers who purchase the 3.x value plan will be guaranteed version 3.71 support for the full year of the plan."
