Right there with you, but have a feeling we will be waiting a long time. Did your install nag go away recently as well? I just have the little yellow download icon now, but no longer the pop-up.

Haha snap! I was excited about a Christmas update until I saw it had nothing in it apart from some new visualisations. Have been holding out since then for something more meaningful and for them to fix the instrument cluster to make the icons a better size again.
I find it pops up the download icon for a couple of weeks, then gets bored and downloads over LTE (I don't have WiFi in range of where I park so previously downloaded via mobile hotspot), nags for a couple of weeks and then a new version comes out and it starts all over again

Ahhh, Thanks for the info. I'm pretty disconnected when it comes to twitter. Is it worth getting one just to hear about updates, or is it really more for entertainment than information?
Receiving 2021.4.12 now, so it seems there is another small push of this update underway. Previously on 2021.4.11.
No problem. I rarely use Twitter, it's so annoying and also super fast moving. Honestly it's not worth signing up for Twitter if you haven't already. Elon will use it as a soapbox to speak to the masses or just say random crap... The thing is sometimes that random crap turns into actual product/an update/etc. If you're on the forum here then I think you'll be good enough.
This "Button" thing was a tweet from Elon and the Tesla fan boys blew up over it.

I fully expect when we do get "THE BUTTON" and we press it it will surely just FART.
This update seems to be picking up pace - TeslaFi shows 400+ cars receiving this version now (and growing) - up from 20 when my car got it earlier.
Yes. He's one of the smartest, most accomplished people on earth in most regards. But he is a complete doofus in what he has said about FSD over the years. Not the technical challenges, but the way he has misled early FSD purchasers.
Um, am I wrong? Maybe I am since I own two of his company's cars but if there was something that could compete with them (honestly right now there's not) then I'd own that. C'mon Rivian!
**Off topic** It's a love/hate & shut up already relationship with Elon. I'm grateful for the car and whatnot and awesome ideas but STFU on Twitter... I'm tired of having to listen to co-workers as me about what stupid crap Elon said on Twitter just because I own a Tesla.

What changes with regen in cold temps? Does anyone who has an app like Scan My Tesla have the update to report on changes in regen braking levels in colder temps? Right now we've found that below about 70° regen starts dropping significantly. With a battery temp of 68° or below approximately regen drops to around only 35 kW or less. Regen dashes on our Model S appear once the regen drops below 35 kW I believe.
Here is a report of the similar 2021.4.11 update and regen from a guy who used SMT. If cell min temp is above -1.5C you now get regen. It's short term as driving down long hills will restrict regen if battery is cold. As for charging it seems battery must be closer to 5C to be able to charge, but short bursts if regen is allowed at about 5C lower temps than pre 4.11. You also get higher regen at higher soc. I tested with 4.11 and at 93% soc max charge is 8kW (on a 12kW charger), but I had about 25kW regen (1/3). After 36 hours at 0C and 40% soc and no charging/preheat I had about 25kW regen. From the attached curve I guess min celltemp was 2C. I drove 50meters to a SC and got 0.5kW charging for 5mins, then it started to climb so it seems you need about 5C for SC.

Max Regen and Max charging power is now higher than before at cold battery temperatures. It's still zero under freezing temperatures but it ramps up faster than before when you cross over freezing. I've observed similar results on my car, with ScanMyTesla.

I got this one last night too. The cold weather reference may relate to the reported poor performance of the 2021 3P in cold temps. The last update helped by lowering the voltage floor resulting in more power in cold weather at a low SOC. This is being discussed in the battery thread. Perhaps this is an evolution of that. Do people actually skip these updates? I’m new to all of this.
