I just noticed that Sage have updated their online support area accessed by consultants who are supporting their Sage MAS 90 and 200 products.
The update provides information on the following end of life dates for their products (which as far as I can see is unchanged from prior publication):
Version 3.71 – 9/30/10
Version 4.00 – 9/30/11
Version 4.05 – 9/30/11
Version 4.10 – 9/30/11
According to the update posted on Sage’s site:
Sage ERP MAS 90 version 3.71 will be retired as of September 30, 2010. After this date, product updates (including year end) and telephone support will no longer be provided by Sage. However, customers who stay with a maintenance plan will continue to have access to the knowledgebase with articles about the retired versions. For more information, see the Supported Versions document and the Sage ERP MAS 90 Roadmap.
This seems to apply that customers on older versions which while they may no longer be supported with product fixes could continue paying software maintenance in order to access the support knowledgebase.
