Ok, I have long since forgot the answer to this, hence my posting.
Presently my car is running on 2020.4.1 xxxxxxxxx
2020 is the year, 4 is the week it was created. What does the 1 stand for?
1 = the first buggy update of week 4.
Got it. Thanks.
Any insight on what the other numbers stand for? For my car it’s 4a4ad401858f
It's likely some kind of checksum on encoding only Tesla knows. It's not important outside of Tesla. Everyone with the same version has the same hex number following it. It's not unique to a car.
I am just amazed that I got an update so soon after it was created. I think this is the fastest I have received an update in 6 years.
The last hex digits is what’s called the “build number”, not sure if it used to list which modules that were used during the ‘make’ command line when creating the update.
Every identical version has an identical hex build number, so I don’t know why Tesla even shows that in the UI.
EVRider, I am compared to probably most here, not really software savvy. Is the hex build number the actual software code “name”.
As an Electrical Engineer that spent most of my career programming new computers to verify they met their specifications, the fact that it is in hexadecimal tells me it is a checksum / hash that is used to to verify the integrity of the binary program file.. Why it is displayed to the outside world is beyond me. I thought it was strange the first time it was displayed.
