Does anyone know (or have tested) what this "regenerative braking at low temperatures" improvement is?
For example, if they allow the amount of regen to be the sum of the battery's regen limit plus the amount that can be used for pack/cabin heating, that would be a great improvement. The older versions set the regen limit as the amount the battery could accept, but then used what was needed for pack/cabin heating, and only the remainder (battery limit minus pack/cabin heating) went into regen battery charging.

More likely they just increased how much you could do, possibly back to what it used to be in 6.2 which several people say wasn't quite as aggressive at limiting the regen in the cold

I thought the "as aggressive at limiting the regen in the cold" was simply a byproduct of v7 being less aggressive at heating the battery pack beyond minimum requirements (particularly with range mode on)?

Maybe that's what they changed, who knows, Tesla isn't well known for their transparency on such things.
I had to leave unexpectedly this morning, so I wasn't able to preheat the battery. Due to that its hard for me to say what impact the update had. However, the limit felt like it cleared very quickly. I'll preheat tomorrow and based off todays experience I'm wondering if the regen limit will be gone after I preheat. My car is garaged and normally its 40-45º F inside.

When you felt like the regen limit cleared quickly today were you driving with range mode on or off?
Thanks.

v7.1 (2.12.22)
My SP90DL was just updated from v7.1 (2.9.154) to v7.1 (2.12.22). I seem to be the first one listed on the Firmware Tracker. Did anyone else get it?

Tesla is clearly on a tear with the second digit for the build number. We just got a report of 2.12.22 in the firmware tracker (from a P90DL with a 100k VIN number), received OTA. Apparently still 7.1, which now spans 2.9.x - 2.12.x

Was a quick update - the only thing listed in the "with this update" section (the upper portion of the release notes that isn't the same as prior) is that now Creep settings will update with driver profiles. Previously, the creep setting wasn't part of the driver profile.
Also - this update enables autopilot on pre-50,000 VIN cars.
(one of these things is not true)

Looks like I was the first recipient of 2.12.22 to post on the Firmware Tracker, so I'll get the honor to name this release. Wow, I feel like I won the lottery! I just took photos of the extensive Release Notes and I'll post them here shortly.

It would be great if people would add entries to the firmware tracker at Tesla Firmware Upgrade Tracker Web App

I got a new update on my car last night while it was at the service center, not sure what it was but I will update the tracker when they drop off my car today.

To warrant the update, any revision might also "fix" some previously undisclosed "features", right?
