Lots of folks trying to play vassal on the old version but I want to let everyone know that there's a mandatory upgrade to version 6.0 to play.

It has more accurate firing arcs but is not compatible with 5.7

Team covenant website has the info.

Anyone doing vassal has to update.otherwise you'll set up a game only to find out the firing arcs are not working

I made a thread about it (with a more direct link to the module version information). It got eclipsed down to page 2 quite fast, though.
