Today I installed 36.2.1 in my pre raven MS 100D FSD. I have HW2.5 and I definitely see bright orange traffic cones. All other visualizations are better as well. Also, I notice an extra loud chime when reversing out of my rather tight garage door...
These are supposedly HW3 indicators but I am sure I have HW2.5 because I have a service appointment scheduled to upgrade. I just received a second confirmation text that they will do the upgrade at my house next week and that I will be receiving a software update a day or so before and NOT to install it.
