If they accepted a software update, I would assume it would be about things that are deliberately programmed in, rather than just fundamental limitations? But I agree it's a bit odd. The longer description says
> The FSD Beta system may allow the vehicle to act unsafe around intersections, such as traveling straight through an intersection while in a turn-only lane, entering a stop sign-controlled intersection without coming to a complete stop, or proceeding into an intersection during a steady yellow traffic signal without due caution. In addition, the system may respond insufficiently to changes in posted speed limits or not adequately account for the driver's adjustment of the vehicle's speed to exceed posted speed limit.

"entering a stop sign-controlled intersection without coming to a complete stop" sounds a lot like the thing they already issued a recall over in Janary 2020 (further down the same web page), so it seems a bit odd that it would still be an issue. And "due caution" to yellow lights seems like it could just be tuning some parameter. On the other hand, failing to recognize turn-only lanes sounds more like a failure of the computer vision system...
