It's been two years since this repo has been updated. A lot has happened since then. Everything's happening here these days for the 2018 onward (until M1) models: https://t2linux.org/

For the up-to-date state of support, see: https://wiki.t2linux.org/state/

If you could mention this near the top of the README, and maybe add a deprecation warning, that'd be great.
