the ui vm has a UI_GETAPIVERSION but the others do not. if you wanted to make everything automatic, you would need to check that for 3 or so (I think it was) before starting up the server. which is kinda messy.
the other vms have no api version info, thus any incompatibilities WILL result in issues.
I don't know what the protocol changes would actually be. at a guess probably just reorganising the entity/player state structures and reordering/resizing the network representation of them. quite probably clc_move got rewritten too. wouldn't surprise me. other than those I've no idea what there is in the protocol that would be worth actually changing, its quite a simple protocol really, once you get past the huffman and bitwise stuff.
I seem to remember two variations on CG_GETGLCONFIG too, but don't recall anything more than that.
