title: Why Does GitHub Create Releases for New Tags When I Push Them to It?
body: <p>GitHub seems to be creating releases out of tags whenever I push those tags up to a GitHub repository that I've cloned to my own machine.  How do I prevent GitHub from doing this?  If I wanted a release, I'd go into GitHub and <em>create</em> one from a <em>pre-existing</em> tag, but I don't want <em>all</em> of my tags to be associated with releases!  </p>
