title: Add a commit to a release that was created before the commit
body: <p>I've just created a new release for my repo on GitHub (<a href="https://github.com/Lrnk/self-esteem-snake/releases" rel="nofollow">https://github.com/Lrnk/self-esteem-snake/releases</a>) and almost immediately afterwards realised that I'd forgotten to commit a change that I wanted to be in this release. I have now committed that change.</p>
  
  <p>Is there any way to add commits to releases/tags after they've been released? Or is my best bet making a new release with the changes included?</p>
