No caching plugin. but my host, EasyWP, does have a Clear Cache option that I run after notable updates.
re: “what exact version do you use? I think I broke something with 9.2.0, so you should definitely use 9.2.1!”
I’m on version 9.2.1, which was updated on 8/3, and my most recent new post was on 8/6, after I updated the plugin.
