Firmware 7.0 2.9.68 which my SC installed last month, states in the release notes "the auto windshield-wiping logic has been improved".
I've been pleased with the more accurate intermittent wiper handling of water volume changes against the windshield, especially as the drizzle is slowing down. I also don't remember the wiper speed going temporarily nuts like it used to, as I've driven around in the last few days of rain we've finally had here in SoCal. I do though, still have chatter on the lower driver-side blade even after a physical adjustment by the SC (I believe that requires Tesla prioritizing Engineering specifying a new blade that is more rigid like my former Lexus SUV had).
