Question with regard to the upcoming 1.05 update

[PawelM]

I was not following posts on the forthcoming update 1.05. I am only aware it is imminent...

I only wondered how it will affect all the PBEM games in progress in I update the game? For instance, should I expect issues even if both players update the game, i.e. if the game has been started on current 1.04?

I have quite a few large scenarios going (including team games), which are likely to take months to complete and I wondered it this means I have to keep a copy of 1.04 installed somewhere?

Anyone knows what to expect in this manner?
