After a much longer wait than what I wanted, a preview of the Physics Update is now available on a new branch called "beta-build". Technically, this is preview is the same as the new demo version (which has also been updated). I published the demo to the beta branch just in case those who have bought the game are unable to run the Demo. Over the next few weeks, I intend to update the beta branch to the full version as I reimplement the features for the full version. There will be another announcement once the Physics Update goes onto the main branch.

Change Highlights:

• New Terrain Generation for more natural-looking Terrain.
• Superstructure Assembly no longer uses Unity's joint system, which should allow for smoother rotation around larger distances.
• Gravity simulation below planet's radius reduces gravity linearly with ratio towards center. Gravity above planet's radius is unchanged.
• Hopefully a bunch of performance enhancements.
• In-game axis assignments!
• Input response viewer.
• More control assignments (eg: custom zoom controls).
• Can disable joysticks in-game.
  

• Reduced number of planets for progression to just one.
  

• Visual orbit indicator now draws the entire orbit (unless the orbit is an ejection orbit).
• Docking port on command module modified for easier docking.
