 ## Detailed changes:
 
 - Thermal runaway protection enabled
-- TMC2208 configured in standalone mode
 - Stepper orientation flipped (you don't have to flip the connectors on the board anymore)
 - Linear advance enabled (Off by default. [Research, calibrate](http://marlinfw.org/docs/features/lin_advance.html) and then enable with `M900 Kx`)
 - S-Curve Acceleration enabled
