I don't remember too much for this version, but there have been substantial changes to the Chandrasekhar Battlecruiser to flesh out its functionality:

• Point defence cannons have been added across the ship's hull, able to intercept incoming missiles or attack the player should they come too close.
• HP values have been adjusted so that higher maximum HP is possible, but the Chandrasekhar in the Shipyard mission has a percentage of that maximum HP owing to its unfinished condition. Additionally, when that level is further developed, destroying the ship will be unecessary.

As for other changes that I remember:

• Missile trail effects have been fixed to work properly with the shifting world origin- no longer will they jut out or disappear.
• Missile afterburners and trails only display when the missile's engine has started up properly (about a second after launch), and the SFX timing has been improved.
• Point defence cannon targeting has been fixed- they will now never get stuck flicking between two targets but never shooting.
• Buffed Altus pitch strength slightly
• A bug that caused having one pip of power in weapons to have the same effect as having emergency power to weapons has been fixed- now having one pip of power will cause weapon power to stagnate.
• Nerfed Asag pitch strength- this makes it more possible to dogfight an Asag without perpetually looping between headons. (so long as you make good use of the stabiliser)
• Buffed HEP missile acceleration
• Added new VFX and SFX for the course 3 escape sequence
• SFX have been added for successfully docking
• The AI test scenario is now available in the build, but does not provide any new gameplay. You can watch the AI navigate a tunnel, try that out for yourself, and/or fight a Chandrasekhar.
