This release is a foundation layer for resolving several issues widely discussed in the support forums for older versions. Although 3.1.0 will inter-operate with any other 3.x.x version of the BBHN software in the same ham band and with the same SSID, users should move to the 3.1.0 to get all mesh nodes on a stable platform and to enable additions like the tunnel feature and software upgrades. WPA3 via Unifi APs. So I know quite a few people around here use the unifi APs.. Figured drop a little note in case anyone is interested.. With release of their controller 6.1.51 (beta) they have finally enabled wpa3 for most of their AP.. There is a list of all that are supported on their forum post about the release.
