The Tesla CEO tweeted out this weekend that the forthcoming Version 9 software update for Tesla vehicles will "begin to enable full self-driving features." It's likely that this is in reference to the "Full Self-Driving Capability" that Tesla offers as a $3,000 upgrade over its Enhanced Autopilot package, which costs $5,000.

When asked for an elaboration on his tweets, a Tesla spokesperson said the tweet is the extent of what they're sharing for the moment.
