you should move but its not really recommended since there is a bug that doesnt let you get any other signal BUT mars, just wait until full release of 0.8
I would recommend that you stay on your current version for the time being. This release is a test release for public feedback. Stuff will be broken, changes may not be liked, and so on so forth. I would recommend waiting for a stable build rather than moving just yet.
You know you won't hold back, will switch to 0.8.0, and then will get your experience ruined by the game-breaking bugs. So don't even ask, go impulsive, and satisfy your curiosity, it's 0.8.0!
