A couple of people have noticed that there appears to be a new version of the Flash Player (126.96.36.199). However, this version only includes the debug, standalone and External (test movie) players.
There is a technote listing the currently player versions which you can read here. From the technote:
Builds 6,0,47,0 and 6,0,50,0 are functionally identical.
I hope that clears things up.
