Plain core. I don't think the laptop is very up-to-date, that core version is probably a few years old. And that one actually gets left off for periods of time, switched on occasionally to update the chain backup to current. The Pi is always on, and runs mempool as well - which is always up on one of my screens, so I know fairly quickly if it is having any issues.

I think I updated the core version on that last week, maybe the week before. It was about a year out of date. Actually I know I updated mempool, because now I can reverse the direction of the blocks on the display. I checked for updates on everything else, and I think I updated core and lnd because they were behind.
