Went to Admin Dashboard, showed I needed an update.
When to Update, showed Docker and Discourse needed the update.
Updated Docker.
Verified the site still worked.
Went to the Dashboard, to the Update, updated Discourse.
Clicked the Dashboard link (left sidebar) and it took me back to the dashboard, but showed me as still using the old version. Refreshed the page, and the updated information appeared.
So some sort of caching issue as far as what it shows, but since this is a very natural thing to do after an Update (click that Dashboard link), it should be handled in a better way.
Thanks.
