I have just recently started using rails for a project and have never had to upgrade before.

I wish they would go over how to upgrade rails in their announcement or link to their own guide. I imagine its just a one-liner. Searching their own site for upgrade doesn't show anything immediate either.

Of course I can look it up very quickly with Google, so its not a problem, but it seems like something they should do.

(I commented there requesting the same)

You just need to change the version of Rails in your Gemfile from 3.0.5 to 3.0.6 and run bundle. Or, if you have

    gem "rails", "~>3.0"

in the Gemfile then I think you just need to run bundle to get it updated.

You usually need to run "bundle update rails" when updating the Rails gem instead of "bundle update", but it will gripe at you and let you know if you try to just run "bundle update".
