I am currently my RAK7258 (Firmware: 1.3.6_RAK b150, Mode: Packet Forwarder) with ChirpStack v3 and I would like to upgrade to ChirpStack v4? In the LoRa Network settings I can only select ChirpStack v3.
Is it compatible with v4 even when using v3? Or will there be a firmware upgrade in the near future to support v4?
