Updates to Model S since refresh?

[mnewman]

Sorry if this already exists, but is there a list of updates to the refreshed Model S since introduction? For example, models manufactured after XYZ have a central mounted horn and models manufactured after XYZ have updated taillights? Are there any other updates to the refreshed car?

Mid February Taillights, Headlights, Radar Removed. Center Horn button November (no firmware yet). Probably lots of other hidden stuff. Some later cars have trailer brake controller connector under dash.
