As far as I know, the Framework team had to update the type C expansion cards for the FW 16 model.
The old ones were designed for 100W on the power lines via USB-PD, while the FW 16 requires testing and certification for 240W for the new USB-PD-EPR standard it uses.
Higher voltages (48V vs 20V) require better insulation and shielding against electromagnetic interference from the power lines.
