I received my update to 2021.32.21 from the factory firmware 2021.3.106 on Monday evening. Which makes it my first software update. I noticed in the release notes, that it included a number of other releases too. I'm not sure if it's in my head but Autopilot is a lot more squirelly now. It closes in on cars at the stop light really close before it initiates any braking and today it veered too close to a semi truck in the right lane, given the freeway was being resurfaced so instead of lines, it had the temporary reflector tabs. I had to force the car away before it disengaged. AP seemed to be more predictable and easier to trust/use before the update.
