Hi
The next release is a bit late, we've been working in the hydroachoustics, new sky code, hydrophones (hydrophones arrays + equipment (and their screens + characteristics obviously) depend on the uboat type, and period of war). The new sky code is already implemented, and working. The night sky still needs work however. There's major work going on with some of the infrastructure, work that had to be done in order to have better AI, and provide accurate detection characteristics, in relation to the equipment type that you can have (equipment that once again, depends on uboat type, period of war, etc...). There were also some fixes so that dangerdeep now builds (and runs) fine on x86-64 (and with gcc 4.1). Freebsd ports are also included, and there are more features (rangefinder "e-cards" for UZO and periscope), the sea code was changed a bit too i think, and well as the convoys code (new tanker is working already).
As for a release, it should be as soon as the new detection code and done, and the hydrophones are working.
Btw, a mission editor is in place too, but this is mostly for developers use. But, this is going to be a major release, at least if you compare it with our last release (0.1), there are tons of new stuff implemented (and being implemented).
Stay tuned, i'll post some news here as we approach a release
