Tesla will begin rolling out its latest software update, Version 8.0, on Wednesday evening.
CEO Elon Musk revealed details about Tesla 8.0, which is the company's biggest software upgrade to date, during a press call earlier this month.
"This is a major overhaul on almost every level compared to V7," Musk said via Twitter on Wednesday.
The release will be gradual so that the company can ensure there aren't any "small regressions," Musk said on Twitter.

The update will include significant updates to Tesla's semiautonomous-driving system called Autopilot. In fact, Musk claims the update will make Tesla vehicles three times safer than cars without Autopilot.
"I think it will make the Model S and Model X by far the safest cars on the road. I don’t think there would be a car that is even within a multiple of the S and the X," Musk said during the press call

Musk said Tesla has improved the accuracy of Autopilot by making more use of the radar sensor on Tesla vehicles. Until now, the radar sensor has been a supplementary sensor, but now it will play a greater role in determining whether an object is a danger. The camera and imaging-processing system that currently powers the semiautonomous system will still be used, but the data collected by the radar will carry more weight when deciding how the car should react when in Autopilot.
Musk said that he believes that the change could have prevented the fatal accident that occurred in May, when 40-year-old Joshua Brown crashed into a semitruck while driving down the highway using Autopilot.
As part of the software update, Tesla's Autopilot will also be able to automatically take off-ramp exits and will have improved Autosteering.
Because Tesla cars are connected to the cloud, the company can push out over-the-air software updates to give its cars new features. The electric-car maker rolled out its last big update, Tesla 7.1, in January.
