I'm slightly confused. The new firmware for the EAP655-Wall (EAP655-Wall(EU)_V1_1.6.2 Build 20251107) requires an Omada Controller version that hasn't even been released yet as a hardware or software version (except perhaps as a beta)...

Recommended Omada Controller version 6.1 or above.

Do I now have to wait to update until Omada Controller version 6.1 is released, or is this a typo and it should be version 6.0.1?

If so, then the error has been carried over to the release notes for version 1.6.3.
