Detailed Updates List
CRAM - Point Defense Weapon
Ships can now be equiped with CRAMs, low-caliber but rapidly-firing point defense weapons. They don't do much damage to ships but provide a good layer of defense against missiles. They can also selectively be used to target ships, but can only damage sensitive modules located externally on a ship.
Radar Updates
The radar is much more engaging. Players can enter passive or active mode. Passive uses infrared (heat detection) which doesn't alert enemies of your presence. Active mode usings your radar, sending out pings that can alert ships of your rough location, if they are equiped with the proper sensors. From the radar system, players can lock onto targets, providing the ship pilot and any players in weapons with detailed information like velocity tracking and location of the selected target. The radar operator can also launch missiles at tracked tarets.

Pipe Damage Mechanic
Pipes will leak hydrogen, oxygen, water, or steam. They will leak continuously until the resource is depleted, a player shuts off a pipe valve, or the leak is repaired. To repair, players must first flatten out the section of pipe that has been damaged via a wrench. Players then must weld the pipe to stop the leak.
