How to detect firmware version for RAK7268

Thank you! My 7268 is on firmware version 1.0.1_RAK rRAK-96aa330 .

Should I upgrade the firmware - and if so - how do I find out what the latest version is, where to get it, and how to install it?

The reason I am wondering about the firmware version is because last month I had 10 to 20 times the normal amount of cellular data usage for 2 days (20 the 40 MB/day instead of 2 MB/day) and had to disconnect the gateway.

When i look at this forum post:RAK7249 - Large Data Usage Problem - #11 by kwinz the solution is was “Updating the gateway firmware to WisGateOS V1.2.3 fixed the problem for me.”

Thanks for the help!
