Tesla CEO Elon Musk confirmed on Twitter on Wednesday that version 8.0 of Tesla’s software for the Model X and Model S will begin rolling out gradually tonight. The software will includes several changes, the most prominent of which is improvements to Autopilot to make the system safer for drivers.

As Tesla noted back in September, version 8 of its software will include “more advanced signal processing to create a picture of the world using onboard radar,” which was added two years ago. Radar, Tesla says, was “only meant to be a supplementary sensor” but is now playing a bigger role in allowing the car to better understand its surroundings. ”

Software 8.0 unlocks access to six times as many radar objects with the same hardware with a lot more information per object,” Tesla said earlier this month.

On Twitter, Musk discussed a few other features including “always-on max temp control for keeping kids and pets safe from overheating.” Musk said this can automatically keep the temperature below 105 degrees Fahrenheit.

Musk said it will be a gradual roll out, so you may not see the update tonight, that’s just when it will begin.

Here’s a look at the full list of changes to Autopilot that were first discussed earlier this month:

Additional Autopilot Release Notes

  • TACC braking max ramp rate increased and latency reduced by a factor of five
  • Now controls for two cars ahead using radar echo, improving cut-out response and reaction time to otherwise-invisible heavy braking events
  • Will take highway exit if indicator on (8.0) or if nav system active (8.1). Available in the United States initially
  • Car offsets in lane when overtaking a slower vehicle driving close to its lane edge
  • Interface alerts are much more prominent, including flashing white border on instrument panel
  • Improved cut-in detection using blinker on vehicle ahead
  • Reduced likelihood of overtaking in right lane in Europe
  • Improved auto lane change availability
  • Car will not allow reengagement of Autosteer until parked if user ignores repeated warnings
  • Automatic braking will now amplify user braking in emergencies
  • In manual mode, alerts driver if about to leave the road and no torque on steering wheel has been detected since Autosteer was deactivated
  • With further data gathering, car will activate Autosteer to avoid collision when probability ~100%
  • Curve speed adaptation now uses fleet-learned roadway curvature
  • Approximately 200 small enhancements that aren’t worth a bullet point
