Ubiquiti UniFi Firmware Release Notes: 3.9.27.8537-4.0.21.9965

Sorting out all the different software releases from Ubiquiti can leave one in a bit of a tizzy (or at least it did me at first). Essentially things break down like this:

  • Most UniFi Equipment (APs, switches) – gets the general firmware release
  • UniFi Cloud Controller – this is the control software, the other software is installed on the individual devices, this is the management UI you use
  • UniFi Security Gateways – get their own firmware
