The firing rules have been updated as well, to provide clearer and better explanations for how things work.
Notable rules changes:
*Group fires are now a thing, suitable for larger platoons with a lot of attached support.
*Bonus dice versus targets in the open.
*Reaction fire is now not restricted if you fired (to fit the new turn sequence better) but troops suffering ANY status effect may not react.
*Units can snap fire multiple times in a turn (which I think is the way everyone played anyways)
Probably a few other little things.
Go download the new file. Do note there'll be new chapters added for Recovery/Rallying tonight or tomorrow so maybe don't print it out just yet.
Also note, during the update process, rules chapters that haven't been updated yet may have inconsistencies. Updated rules take precedent.
