Is there a changelog for all the hardware changes in the Model 3 over the years? I can't seem to find one. I made my own, but I haven't gotten everything for the Highland refresh. If we don't, we as a community should make a list of all changes that has happened, along with a list of references if possible.
*Important: Tesla makes running changes throughout the year, so a 2019 car may not have everything under the 2019 list of changes depending on the month you got it. If the time of change is known, it'll be added. Otherwise, it's unknown what month the change happened.
