Nope, I only have one KSP install and that was downloaded after when 1.0 came out, and has all of the new parts and effects in, so I can confirm it is 1.0, and KAS still works, the only other mods I have installed are some of the USI mods that were updated, as well as mechjeb as I mentioned before. - - - Updated - - - After a bit of more experimentation, the only thing i have found not to work is the containers, they do not attach to anything in the VAB or SPH, and due to this i cannot obviously try them on a craft.
