What's my Game version

So after christmas I bought the goty edition of borderlands 2 and I tried to find out the version number and I read somewhere that if you go to the matchmaking browser than the game version would be in the bottom left of the browser. So I did this and it said 1.0.11 but I read that the ps3 version goes all the way to 1.5.0 and it says I have the latest updates. So what version do I have it’s really confusing

Last update was October 2015, which you can read about here.

I think that all the updates have been version 1.0.x, not 1.x, so it sounds to me like you probably have the latest version.
