A really big day for Wargame Design Studio

[berto]

From the change log for France '40 4.00:

Revised default optional rules...Alternative Indirect Fire Resolution, Alternative Air Strike Resolution and Alternative Direct Fire Resolution have been removed.

I'm assuming this means they have been removed as defaults, not that they've been removed from the options available to players, but please tell me if otherwise?

The rules have not been removed.  Rather, defaulting to those rules has been changed.  In all cases, once you have set your preferred rules, that is saved and carried over to future games.
