What is the difference between supervisorctl reread and update?

Question

linux

Hello. Can you please explain what is the difference between these commands?
I updated the worker code (added several functions), do I still need to restart (I didn’t update the config)? And in what cases can they be used? I read it, but I still can't figure it out. Thank you.

This command only updates the changes. It does not restart any of the managed applications, even if their configuration has changed. New application configurations cannot be started, neither. (See the “update” command below)
Restarts the applications whose configuration has changed.
Note: After the update command, new application configurations becomes available to start, but do not start automatically until the supervisor service restarts or system reboots (even if autostart option is not disabled). In order to start new application, eg app2, simply use the following command:
// EDIT
Well, let's chew.)
We changed the code of the workers - restart.
Changed the configuration (number of processes, logs, etc.) - reread (gives the supervisor information that the config has changed) + update (restart only those workers for which the configuration has changed).
If you have any questions - write more.
