System - System version wrong

I have loaded Volumio 4.073 for a Raspberry Pi 3B. Checking System / System version shows version 3.886 Dated 11/12/25. What version am I actually running - how can I check?

Version 3.886.
You did flash a new SD with V4?

I’m pretty sure I did. I was doing 3 different Pi’s at the same time so it’s possible I got something wrong. Can I check from checking the Linux version from SSH / Terminal?

 cat /etc/os-release | grep VOLUMIO_VERSION

Argh - this is my error. It looks like I loaded version 3 in error. I now have v 4.084 running on my Pi5 and I’ll load that onto my Pi3b later.
