The Daildalos team has continued working on official patches for our beloved IL2 1946. Just about a week ago they finally released patch # 4.12 which contains a lot of new stuff and changes. As far as I know there have been no words from the HSFX team when they will include 4.12 into the a new HSFX version, but normally it takes 2-3 months. Considering it's summer time, I would say that we have to wait a bit longer for that - but who knows.
You DO have vanilla backup for 4.11, don't you fellas? :)
