Not sure if there's even any correlation or requirements between the server versions and the agent versions.
The AE Compatibility Matrix (253_WA_AE_Support_Matrix.pdf) available though docops.ca.com has a table "Agent Compatibility Matrix" give you the agent versions and the supported WAAE server versions. Not quite the handy dandy cross reference desired but it does help.
You can start from these links:
About what System Agent release is shipped by any CA WAAE release:
When you expand the .iso image of the CA WAAE scheduler DVD, select your platform, then select the "AGT" directory, then "patches".
For example, on the CA WAAE 11.3.6 SP6 image, this "patches" directory name is "1-SP7" which in fact contains the files used to install/upgrade the System Agent to 11.3 SP7
If you repeat the same exercise with the CA WAAE 11.3.6 SP5 DVD, you'll see that it brings up the System Agent to 11.3 SP6
With the CA WAAE 11.3.5 DVD, for Linux, the "patches" directory contains 1-RO51863.
This patch is is about: LNX-CA WA AGENT R11.3 SP1 CUMULATIVE 1
i believe you are looking for the hyper email. you need to sign up for it if you want notification.
the compatibility matrix is what you need to know what you can use.. db type. autosys version wcc version eem version and agent versions.
In addition to my last updates, I am going to ask Product Management to add the maintenance level of the different embedded products like the System Agent, EEM, CCS in the GA announcement letter of any New Release or Service pack
