I just got a digest email alerting me to a change in the article https://community.intersystems.com/post/studio-tip-running-cos-commands-...
and when I use the list-style view of the dashboard it appears at the top with a recent "updated" timestamp:
But when I open the article the date info on the article and on all of the comments all points to changes 5 or 6 months ago.
I wonder if someone voted up the article earlier today and perhaps that triggered the update notification. If so, I think that's a bug. I don't want to know every time someone votes up (or down) an article.
