First, because of my obsessive-compulsive disorder, every time I see updates in the background, I feel uncomfortable. Second, I think about it when I see an uncomfortable situation, the plug-in and system will be upgraded after the upgrade.

So if you have obsessive-compulsive disorder, add it to your favorites!

Note: update_core indicates system upgrade, update_plugins indicates plug-in upgrade, and update_themes indicates subject upgrade.
