Mesh issues when using 4.2.2-r5

All E600s and E700 that meshed went down after 4.2.2-r5 upgrade.

The E600s were completely unavailable. The device wouldn’t ping and connected devices wouldn’t pass traffic. The e700s stayed meshed, but attached clients wouldn’t pass any traffic. Downgrading the mesh master fixes the issue.

Is anyone else seeing this?
Is there any setting changes needed when meshing in 4.2.2-r5?

There is one known issue in 4.2.2, if WLAN security is PSK and configured VLAN is other than VLAN-1. Issue will be fixed in upcoming builds
