The warning came from a repair shop that specializes in Meridian equipment.

I've looked at the firmware release notes page, and it seems to only reference version information for the configuration and update programs, not the products (speakers, processors etc). I recall seeing a page, which I can't find now, that showed v5.2 and 5.4, but nothing before that. I thought that there might be somewhere that contained the whole list of firmware notes.
