Latest RHF76-052 Firmware please

My original Seeeduino LoRaWan boards have modem firmware version 2.1.18. Some newer boards I bought recently have version 3.3.1. I would like to update the older boards. Could you please provide the latest RHF76-052 firmware? Possibly add the file to the “Resources” section of the Wiki page https://wiki.seeedstudio.com/Seeeduino_LoRAWAN/#resources ?

Many thanks, Dave
