I made a thread on reddit before I found these notes (apologies), but from what I can tell, thrusters have simply undergone a massive nerf, rather than buff.
I had taken screenshots of my ship recently and after patching (coincidentally), and in essence, all my thurster related values were reduced by 76-77%.
Brake: 188.5 -> 43.7
Yaw: 1.51 -> .36
Pitch 1.95 -> .46
Roll 1.59 -> .37
I did some testing in creative, and took 5 sheets in layers, then combined them, and they reduced the net thrust. Meaning they had a reduction in thrust tied to a reduction in surface area independant to volume.
The way I read the notes, I didn't think I would lose the ability to have a nimble ship, and hope this isn't the only direction past a certain size.
