CentOS 6.1 released - how can I take advantage?

I've been on Linode all of 10 hours so far, and what a thrilling ride. Went from install of CentOS 6 32bit to a LEMP install, ssh keys and all my DNS configured and everything running great. If part of the premise of Linux it to have a lot of fun, we're doing fine.

Of course, today CentOS announced immediate availability of Cent OS 6.1.

I have a similar CentOS 6 install on a VM on my MacBook Air I'm using as a test/dev server, so, I'd make the changes there first, and could roll anything back, but, how can I update my installs to take advantage of the new 6.1 packages?

I figure this is a great time to do it, since I have not really started developing up the new site, so, if we were going to trash the system, this would seem to the be the time to do it, lol. The only thing at risk right now is my configuration, which I could redo in a few hours, and my old site is still up for a couple of weeks if I had to point the DNS back at it. So, let's do this!

Are Linode backups free or do they cost money? My site is small and I'm a video/multimedia/web guy, so, I would be (and have been) fine on a $6 shared host really, but this Linode thing really feeds my inner geek.

EDIT: I'm guessing this could be it?

But is this the way to do it?

Thanks.
