title: How do you release a bugfix to a previous version and tag it?
body: <p>We are trying to adopt gitflow into our process at work. Gitflow is pretty simple when it comes to hotfixes. However, I'm unclear on how I would fix a bug on a previous version of our system.</p>
  
  <p>For example, let's just say we're on version 8.1.3 and I need to make a bugfix to 7.1.5. I could create a branch based on the 7.1.5 tag, but then how do I get that back into master and tag it? Is that even possible using Git? I was thinking of just keeping the release branches and commit and tag there, but I'm not sure if that is the proper way to do things.</p>
