The first thing to look at to know that you don't already have the latest revision is the new tensioners have two holes where the install pin is inserted. Some tensioners look physically the same and the extra hole identifies the latest revision.

The differences are a slightly different arm angle where it attaches to the main bracket. The tension arm has more travel so the arm does not bottom out before the cam chain tightens. The tension spring is stronger, and the locking device is thicker, plus the locking pin has an extra angle bent into it so it provides a more secure locking to keep it from backing off.

Some of these differences were done on earlier revisions, so the best way to know is the extra hole in the side of the bracket, which indicates the latest version.
