Regrettably we don't log version number. I just see that there is much less logging - this is how I know.
As I mentioned before, it's is safe to move out old packages and let VCD regenerated them. That's what fix in 5.1.2 does. Of course you would need to do it for every cell and you may face sysprep complications if you use XP/2003 OSes.
