How can I stop getting update notifications for El Cap beta updates?

[buckingham2015]

Hey guys, just before El Capitan came out I signed up for the beta, downloaded and installed it. When the full release came around, I downloaded it and reinstalled it. What's annoying now though, is that every day I get an "Updates Ready to Install" box at the top right, urging me to install the 10.11.1 beta. How do I stop getting these notifications? I don't want to install beta software anymore.

System Preferences -> App Store -> Download pre-release software (or something like that).

There should be an option to disenroll from receiving beta-updates.

That fixed it, thank you!
