It looks like you’ve upgraded just fine?

You may want to update your cordova like it says, via npm install -g cordova. Aside from that though it looks like you’re updated.

it doesnt say

Ionic Framework Version: 2.0.0@rc5 or whatever like i expected… how do i know i am on release candidate 5?

Ionic 2 Final was just released an hour or so ago. No need to be on RC5.
