Traveller is an odd one to list as a stable version.
It actually changed quite a bit and strayed from the original quite a bit, if you were close to the game, if you weren't they did look very similar. Except Traveller 5th edition (not the 5e D&D version upcoming, but that actual 5th version of the Traveller rules) which I think was obviously different while still being somewhat compatible.
Then there is T20 and the GURPS versions (yes TWO!).
Then Mongoose went back to much closer to original Traveller with their own subtle but great changes (imho) and it's drifted some from there.
