How to stop getting macOS beta updates?

Previously I was using Catalina Beta

A few days back Catalina came out, and I upgraded to it.

My guess is that I am still enrolled in the developer beta testing program, and so I continue to receive betas.

If this is correct, how to remove myself from the beta program?

And if not, what's going on?

Solution 1:

In Software update preferences, click on details under the gear icon and un-enroll there. This stops beta updates.

Emails and feedback assistant features are still there which need to be removed after signing into
