How to get rid of dev build updates?

Ok, so I downloaded the beta version of Yosemite in September. I installed the golden master when it was released to the public. In the system updates it keeps asking me to update to build 14C68M. I don't want to be part of the beta testing anymore. I clean installed Yomisite, but it still asks me to update to a dev build. How do I get rid of this?
