Critical vulnerability in Grin 1.0.1 and older (fixed in 1.0.2)

This post goes unanswered for a month, finally gets and answer, but which doesn’t explain much, and everyone wonders why there are still people running the old node versions. We’re not all linux wizards. I haven’t found clear instruction for newbs about how to upgrade the wallet and node versions. So, don’t be surprised if the network has insecure nodes.
