Satellite 5.4.1 -> 5.5 on RHEL 6.4

So it looks like 6.4 dropped overnight.  Just so happens that I had the upgrade from 5.4.1 to 5.5 scheduled for tonight. 

Has anyone done this upgrade yet? (Perhaps during the 6.4 beta?)

If I end up being the first to do so I'll be sure to post about it here afterward.
