Version 1.06b is now available.
Crew voices (work in progress) have been added but disabled by default in version 1.05b. To enable them simply open default/hud/default.txt and change LogVoiceVolume=0 to a value between 0-1 for volume.
Major changes:
Torpedo tubes jamming is a little more generous, tubes can now jam at 20+ knots.
Wire breakage re-worked.
Found the last (we hope) of the AI submarine diving bugs, so now there should be no more diving into the sea floor or past crush depth by Soviet subs.
Torpedo homing logic now uses "lag" rather than "lead" logic so that targets being homed on cannot be outside the sensor cone.
Sinking vessels now become less of a target for homing torpedoes over time.
Improved some issues caused by terrain chunk drawing.
