The tenth stage of the "Van Kanigem" tournament.

I think it's 1.4, 1.41, 1.5, or 1.6.

I'm not sure about something else. The last time I played was at the 5th stage of the Kanigam tournament in Heroes 5. I think we were playing on version 1.5. Since then, I haven't done anything with updates and haven't played Heroes 5 at all. Now, when I launch the game, it says the version is 1.5. So, does that mean I only need to install patch 1.6 now? I just don't understand why people are saying that we're playing on the same version as the 5th stage?
