Version 8 of Tesla’s Autopilot shows 'material improvements': Elon Musk
During the press conference on the release of Tesla’s new P100D battery pack, CEO Elon Musk gave little away on what to expect with the forthcoming version 8 of the Autopilot system. Musk did mention that the software should now be going to final review and that there would be "material improvements in the autonomy of the car" with the work that has been done expected to show notable differences. 

If you don’t remember, we published our exclusive report on Tesla’s v8.0 software update at the end of June. That’s when it entered beta testing. We are now in late August and the update is still not available to Tesla owners. CEO Elon Musk warned that it was taking longer than usual, but now it sounds like the update is imminent.

During the press conference for the release of the new P100D battery pack, Musk refused to answer any question regarding Tesla’s Autopilot program, but he did briefly mention the upcoming v8.0 update:

“One thing I should say though is that with version 8 of the software, which is hopefully going to final review right now, there will be material improvements in the autonomy of the car. I think the amount of work that has been going into version 8.0 will be very noticeable. The improvements will on several dimensions, but that’s only a software update so it will be applicable to all cars.”

As we mentioned in our original report on v8.0, the beta test build was featuring what Tesla referred to as “the most important UI refresh since the launch of the Model S”. It also had highly requested new media and map updates, and as for the Autopilot, it featured automatic off-ramp with the turn signal and improved Autosteer.

That was the original beta build from almost 2 months ago. Tesla likely made some improvements to the update and we could potentially have a few surprises in the wide release.
