Changelog:

• AI ships now form battlegroups. These groups range in size from pairs of destroyers to large task force fleets with submarine escorts, and are usually tasked with either defending their homeland or seizing strategically important areas of sea.
• Numerous improvements to the world map. Land is now in colour (both on the map and when viewed through periscope) so you can sea deserts, snow etc. The positions of several coastal cities have also been fixed, and several narrow straits which were previously impassible have been opened.
• Mouse controls have been overhauled and significantly improved. The controls are now similar to most RTS games - click a crewman to select him, right click to give orders. Mouse controls should now work properly in fullscreen mode too.
• Acceleration of AI ships now depends on their engine power and mass.
• AI ships are now aware of torpedoes and will accelerate to try to dodge them.
• Added Virginia Class Cruiser, Sariwon Class Corvette, Lupo class frigate, Georges Leygues Class Frigate and Kortenaer Class Frigate
• Changed the way flooding occurs when the sub is surfaced. Now water will still leak in through damaged walls, rather than unrealistically rushing out of the sub like it used to.
• Water can now leak in through damaged floor tiles.
• Significantly improved rendering performance, especially when viewing the world map.
• Added Norway, with cities Oslo and Narvik.
• Added 3 new zoom levels to map for easier navigation. Number keys 1-6 control the zoom level.
• Increased size of US, Soviet, British and Chinese navies to roughly historical sizes.
• US and USSR strategic AI now consider controlling the North Sea and Norwegian Sea their primary objectives, reflecting actual cold war doctrine.
• Mechanism to automatically shut Main Induction Valve if flooding is detected is now simulated. It can sometimes fail - in this case the valve can still be opened and closed manually.
• Added sound effect for opening and closing Main Induction Valve.
• Increased damage from explosions, in particular those caused by 120mm+ shells.
• Cargo ships now dock at port more often.
• Reduced power consumption of electrolysis system.
• Electrolysis system no longer automatically switches off when the submarine switches to battery power.
• Nuclear meltdowns now completely destroy the reactor core every time.
• Nations added in the last couple of patches (netherlands, taiwan, etc) now use the correct military aircraft.
• Changed several pieces of UI text to be more descriptive.
  
• Fixed a bug which prevented Chinese Luda class destroyer from appearing.
• Fixed a bug causing submerged submarines to appear on surface search radar.
• Fixed a bug which occasionally caused AI ships to move over land when engaging the player near a coastline.
• Fixed mouse controls for bilge pumps.
• Fixed crash when viewing map near north pole.
• Fixed bugs causing sunken ships to appear on sonar.
• Fixed bugs causing recently sunken ships to be reported as visual contacts.
• Fixed a bug which sometimes caused the "Exit y/n" prompt to disappear before a key was pressed.
• Fixed rare graphical glitch on Weapons Systems Control Panel.
• Fixed rare bug where water flowing out of broken machinery could sometimes pass through walls.
• Fixed bug causing a small amount of water to appear inside lightly damaged walls.
• Fixed a bug where the player sub would constantly try to steer north after sailing under north pole.
• Changed default "cursor toggle" key to F1

Enjoy!
