Product Availability Matrix says V2.4.1 is the latest release but it is out of support.
Is there a newer version, has the name changed or something else?

It is going out of support for z/OS 1.12 on 2014-09-30,
but only because this is the “platform retirement” date.

Which OS are you referring to ?

We are zVSE 4.2

z/VSE 4.2 is out of maintenance by IBM, when you match up the product availability in Empower and the z/VSE Service & Support site you’ll see they are in sync, the latter says

So the next question is: why is SQL42 not listed as available for Z/VSE 4.3 and 5.1, this I can’t tell you so you’ll please have to talk to your friendly support rep and/or contact in logistics, I’m afraid.

Thanks Wolfgang. Yes according to Empower Product Availability Matrix V2.4.1 is the latest release regardless of Operating System. Are you saying there is a later release. Hopefully one that supports ADABAS 8.2 features?
