What code changes which requires phx server restart

Hi,
In dev environment, what file changes (.ex or .exs) when made requires phoenix server shutdown (ctrl-c) and restart?

Thanks!

For 1.2 a rule of thumb was that you have to restart for everything outside of web.

I do not know if that changed for 1.3…

But you will need to restart for changes in mix.exs or the various config/* files (when they are loaded in your environment) regardless of your phoenix version. This is a limitation of how mix works.
