Lee:

According to the z900 announcement letter, the following VM
releases were supported at GA.

    * z/VM 3.1.0
    * VM/ESA 2.4.0
    * VM/ESA 2.3.0
    * VM/ESA 2.2.0

According to the z800 announcement letter, the following VM
releases were supported at GA.

    * VM/ESA 2.4.0 with APARs VM62676, VM62811, VM62942 and VM62665
    * z/VM 3.1.0
    * z/VM 4.1.0
    * z/VM 4.2.0 with APARs VM62938 and PQ51738 for HiperSockets

As you may remember, we announced z/VM 3.1 with the z900 and then
quickly repackaged (and repriced) the product as z/VM 4.1/4.2.
All three releases shipped in 2001.
