"We made a number of hardware improvements from the Librem 5 Aspen to the Librem 5 Birch batch. We have a much improved antennae design, shield protectors across all components on the PCBA, rubber bumpers to help tighten up the fit of component placement, strong clips to secure the WiFi and Cellular cards, shorter cables to clean-up the cable routing, tighter overall tolerance, improved thermal dissipation into the case."
Ezek azért elég komoly változtatások, nem bánom hogy várok :)
