title: Automate Release Notes using Jenkins and Github
body: <p>I have a Jenkins build that will create a pre-release with a tag and then upload an artifact. To add to this I would also like to create some basic release notes, so for now all the feature branches that have been created/merged into master since the last tag.</p>
  
  <h2>Update</h2>
  
  <p>I have found <code>git log --oneline --decorate</code> but can I just get the logs from the last tag? so the commits between tag <code>13.4.0</code> and <code>13.4.9</code> as an example</p>
  
  <p>I guess then after that I will need to parse the results into an array which I can then extract what I want from.</p>
