CatOS 8.2.2 GLX - supported Catalysts?

I was looking at doing a routine CatOS upgrade of my switches and
found that the CatOS 8.2 train has been renamed to 8.2.x GLX.
According to the release notes, the GLX was added to indicate this
train is not intended for Cat6Ks.

I am having trouble understanding about which Catalysts this train IS
supported on, since the release notes don't seem to mention the older
switches. Can anyone tell me if 8.2.2 GLX is intended for:
4003 w/ sup1
2980G
2848 (the notes say 2948G, but I believe
that is the new 48p gb box)

In fact the code loads and runs on all these boxes, but I'd hate to
have a problem and have the TAC tell me I shouldn't be running this
level.

TIA,
