How do we tell if our game is the latest version? There appears to be no version number in any of the opening screens.

I bought mine on Steam and so assumed the patch had been applied automatically. However, one of the issues fixed by the patch is not fixed in my game, so I want to check whether the game was patched by my Steam client.

Grateful for advice.

Usually when you hit Escape or whatever key gets your main HUD menu up, on one of the corners of that window is the Version Number.
