RPi 4 GPIO on OS 5.10

Hi all,

Are there any changes between 4.17 and 5.10 that might impact my ability to use the RPi4 GPIO? Someone mentioned it in a comment on the release thread, but I can’t see anything mentioned elsewhere to back it up.

Specifically, I use a fan HAT to provide active cooling and I’d rather it wasn’t broken by the upgrade:

switch:
  - platform: rpi_gpio
    ports:
      18: RPI Cooling Fan

climate:
  - platform: generic_thermostat
    name: RPI Cooling Fan Controller
    heater: switch.rpi_cooling_fan
    target_sensor: sensor.cpu_temp
    min_temp: 55
    max_temp: 80
    ac_mode: true
    target_temp: 65
    cold_tolerance: 0.1
    hot_tolerance: 0.1
    min_cycle_duration:
      seconds: 30
    keep_alive:
      minutes: 5
    initial_hvac_mode: "cool"

Many thanks!
