This week Microsoft released the latest version of the Microsoft Desktop Optimization Pack for Software Assurance (MDOP) on http://licensing.microsoft.com, including the SoftGrid 4.2 Client and Sequencer which add Vista compatibility.
The CD image also contains the Diagnostic and Recovery Toolkit, Asset Inventory Service, Advanced Group Policy Management and System Center Desktop Error Monitoring.
The SoftGrid versions in the mdop2007.ISO image include:
The SoftGrid Virtual Application Server (VAS) version 184.108.40.2062
The SoftGrid Client version 220.127.116.112
The SoftGrid Sequencer version 18.104.22.1683
Note that only the Client and Sequencer needed to be updated to include Vista compatibility - the VAS version is the same as in 4.1 SP1.
