Hi there,

I love Discourse and the community. Here is a quick question: Say I’ve made some changes to app.yaml, like modifying SMTP settings, is the only and correct way of updating the running config via the `./launcher rebuild app`?

Or is there another way to reload the config without taking the entire site down for a moment?
