The Forgotten Hope Mod has released the .66 version this morning.
The list of mirrors hosting the 295MB incremental patch are here
A listing of all of the changes to the mod is at .65 to .66 Change Log
There is also a very useful FH instructional page at Forgotten Hope School which highlights some of the major changes in play between the mod and Vanilla BF42. I learned a few things here, and you could too.
Lets go play!
