Version 0.21 released!

Changelog:

AI controlled ships can now move around, and warships will actively hunt down your submarine if you are detected. Sonar is now simulated for all warships which were historically equipped with it. Anti submarine weapons are also simulated: many warships are equipped with depth charges, ASROC missiles or mortar systems like the RBU-6000. Evading destroyers is now a real challenge! If detected it's best to stay submerged, move slowly (less than 5 knots is best) and try to either escape or reach a position where you can launch a torpedo at the attacker.
Passive sonar is now simulated for your submarine. Note that the sonar display is clearest while moving slowly and completely submerged - moving quickly, especially while surfaced, will add a lot of noise to the display and make identifying contacts difficult. Your sonar has a 'blind spot' directly behind your submarine due to interference from the submarine itself. No active sonar, narrowband info or towed arrays yet but they're planned for future updates.
Related environmental effects are also simulated, like the thermal layer in water which can distort sonar signals. The depth of the thermal layer varies with ambient temperature, currents etc but it is generally shallow (or non-existent) near the poles and deep near the equator. It is marked in blue on your depth gauge.
Bilge pumps have been added. Select them like a control panel and press + or - to turn the pump up or down, or Z to toggle the pump fully on/fully off. Pumps are more effective at shallow depths.
The submarine layout has been changed slightly.
It is now possible to replace lost coolant fluid in the nuclear reactors. The coolant reservoir is simulated (part of the primary coolant pump) and will take damage over time as coolant leaks out. Stopping the leak then repairing the reservoir will replace the coolant. It's important to identify the source of the leak and fix it BEFORE you repair the reservoir, otherwise the coolant may leak out faster than you can refill it.
Added a couple more ship classes and weapon types.
Made explosions slightly less common and slightly more damaging.
Several other bugfixes, including tweaking the rates for oxygen use in the diesel engines and the rate crewmen breathe.

Enjoy! As a special request, could you please let me know how difficult (or how easy) you find fighting destroyers, frigates etc?
(A good way to get some quick action is to play as West Germany and immediately sail east to Rostock, where you will almost always find some East German ships)
