So if you recently picked up a new Model 3, you may notice it seems to be running an outdated and uncommon firmware 2019.7.105. This iteration is missing sentry mode, enhanced summon, and NoA free lane change. According to a Tesla rep, the features are "there", but not "turned on" due to being on a new hardware. Apparently the firmware from HW2.5 is not totally compatible with the HW3 chip.
That being said, HW3 owners use this thread to communicate about firmware updates, and please share if you have any additional info.
