Version 0.22 released!

Changelog:

• Aircraft are now simulated in much greater detail. They can be selected (targeted) with LShift+T - although obviously they can't be hurt with torpedoes. There are currently 8 types of aircraft in game with many more planned.
• Weapon graphics in the periscope view have been redone. The little red dots have been replaced with proper graphics for missiles, torpedoes, depth charges and cannon shells.
• Overhauled the anti-submarine weapons of AI ships. Now they will fire proper depth charges at you, which you will see sinking through the water around your sub and detonating. Much more realistic and it also looks really cool.
• Added Sweden, Finland and Canada to the game. All 3 nations are playable.
• Added 6 new cities, bringing the total to 65.
• Added many, MANY more crew names and ship names for almost every nation. A BIG THANK YOU TO THE FACEPUNCH COMMUNITY FOR HELPING CREATE THESE NEW NAME FILES!
• Better hydrodynamics modelling has been implemented. Modern nuclear submarines are designed to be submerged most of the time - their hull design means they are most efficient when fully underwater. Your top speed is now effectively limited when surfaced or near the surface.
• Moved a lot of formerly hard-coded data to ini files. It is now possible to create custom submarines - a submarine development toolkit will be available for download soon.
• Sonar range has been increased by 25%.
• Crew AI has been improved. Crew will now avoid fires better and are slightly better at judging risks.
• A mission log has been added. While you play the game, it will record important events to "mission_log.txt" in the game folder. After the mission ends you can read this, make copies of it or whatever. I suggest making a folder to keep copies of your best missions / worst disasters
  *Note that the mission log is erased every time you start a new game*
• SCBA gear (self contained breathing apparatus) has been added. This allows crew to survive indefinitely in low oxygen environments. 2 sets are available in the equipment storage.
• As a temporary solution to the "equipment stuck on dead crew" problem, pieces of equipment will now teleport back into storage if their owner dies.
• Aircraft and ship AI improvements.
• Fixed the radio message bug.
• It is now possible to restart the game without quitting. Simply press R on the pause menu - this will start a new game and randomise everything. You will lose all progress and the mission log will be overwritten.
• Fixed a number of damage models, including the infamous torpedo fuel tanks. Now, as long as the fuel ventilation system is intact, the tanks will never explode. Numerous other systems were tweaked or fixed also.
• The diesel generators will now switch off when you refit at a port, fixing an interesting bug pointed out on the Bay12 forums.
• Fire suppression malfunctions now have a small chance of blowing up the Misc Systems Control Panel.
• Fixed a bug where the game would freeze when playing as a completely neutral nation, because it couldn't figure out whose ships you should be sinking.
• Numerous other bugfixes.
