Hi there, this is more out of curiosity than anything. We bought a 2020 with a build date in August. I know there was a pause due to the battery post recall, but in addition to that I'm aware of at least one other change that happened to 2020s built at the end of the year - the cover added over the front "cyclops" ACC sensor. Are there any other changes you are aware of? I know in prior years late MY changes have been made to address safety issues et al, so just curious. Thanks!
