FSD beta v9 was 4.18.12. I have a feeling 4.20.69 is going to be *special*. :D

I've been patiently waiting to see a version 4.20.x show up thinking there was no way that Tesla would let that go by without a easter egg in the software. If Tesla Fi is any indication - it looks like they may skip it entirely. Still holding out hope though to have a version of software that tokes.
