[Cambium_Lena]

Cambium is officially releasing the PMP450x Radio 20.2.2 software.
Radio software and documentation can be found at https://support.cambiumnetworks.com/files/pmp450/.

It will be available on cmMaestro cloud within a few hours.

The main issue fixed in 20.2.2 is a new PMP MicroPoP Connectorized to get sync from the on-board GPS.

Note, we have found an issue with the NAT entries in 20.2.2. SMs in NAT mode should not run 20.2.2.

If you have a MicroPoP Connectorized AP, you will need 20.2.2 for GPS sync, all other products can stay on 20.2.1.

Sorry for the inconvenience, we will fix this ASAP in an upcoming release.
