I am testing this right now with the 4.5.0 Cam/Cas. Right now I was able to upload the .tar for the client for 4.6.2.1 but when I download and install the file it still installs 4.5.1. I have no idea why. I will go check the support matrix.
I find this weird as in previous versions we could run diffent clients/ CAS versions. After running a manual update I got a new AV/AS list that does appear to support AVG 8.5.
