Thanks to Wayne Schulz for pointing out the availability.

This new roadmap document outlines the next 2 years or so of development.  There are a number of valuable enhancements moving into MAS 4.5 which many of our clients and prospects have been looking for, for quite some time. 

It looks as if the next major release, MAS 90 5.0 will be focused on stronger real time web integration, starting to create some pre-packaged workflows such as Purchase Order approvals. This release looks to be end of 2012/early 2013. 

It will also include the ability to automatically download patches and updates, although not likely install full blown upgrades.

Take a look below for more details
