Firmware 8.6 update

Peplink Balance One router on 8.54 firmware. Cannot upgrade automatically to firmware 8.6. Should I download and update manually?

The Balance One will not be getting the 8.6 firmware update. Only maintenance releases.

Right up at the top of the Downloads web page:

Further major firmware updates will NOT support the following models. They will receive Firmware 8.5.x maintenance releases as needed.
Balance … / One HW1-3 / One Core HW1
