Main changes:

The save file now weighs 6 times less. A lot of the data that was stored inside the file earlier is no longer needed.
Added a «Restart» action to quickly restart a race. The default key on the keyboard is R (can be rebind in the control settings). Not currently available on gamepad due to issues updating the Steam Input action list.
The death animation with smoke can now be skipped not only with the «Pause» button, but also with the «Jump» button.
«Abort the test» button. If you press the button 3 times, the inscription "hold" appears next to it.

Track:

Stage 5-2. The monitor that appears under the aerocycle has become more visible.
Stage 5-3. Fixed a rail break that occurred when quickly activating a monitor.
Stage 5-3. The monitor that appears under the aerocycle has become more visible.
Stage 12-3. Jumping on the finishing ramp just got a little easier.

There should no longer be a "jerky" effect when dashing onto a hanging platform. The aerocycle should now jump smoothly from one platform to another.
Pulling to platforms now works more correctly.
The dash to the left / right has become less sharp.
]The sideward flight distance has been decreased.

Removed all Bit achievements as unnecessary.
Added 2 new achievements that can be obtained by interacting with items inside offices.

Crashes at the time of death should become less frequent. (probably)
The office could crash if you re-view the glass part of the track.
Shadows in the office are temporarily disabled, as they caused crashes for one of the players. Need to do research.
