There never was one that was produced with the TMC chips... they couldn't do what we wanted. Instead we are going to use the AS5600 magnetic rotary encoder which communicates with the electronics via the I2C bus that we expose through the stock electronics.
We haven't released that specific code yet due to time, but it's coming, but the Mk4 upgrade details (which currently include the OLED display and the 3DClippy automatic filament cutter) are already available in the Getting Started forum.
