title: Github releases - are they private for private repo?
body: <p>I think this is a really stupid question but I can't find the answer.</p>
  
  <p>I have a private repo on github. If I create a new release and "publish" it, does anything become public?</p>
  
  <p>I want to keep it all private/internal and I'm not clear whether "release" means public release in any way.</p>
