"Nothing you code outside work is cleared for public release."
Locate that cluse in your employment contract and cross it out and initial before you sign it. I'm willing to bet this is entirely negotiable and nobody will even blink. I speak from experience. After all, you own intellectual property already and it needs maintenance. So no, they don't get to own work you do on your own time.
If the company pushes back you really don't want to work for them. Seriously.
