title: How can I move a tag on a git branch to a different commit?
body: <p>I created a tag on the master branch called <code>v0.1</code> like this:</p>
  
  <pre><code>git tag -a v0.1
  </code></pre>
  
  <p>But then I realized there were still some changes I needed to merge into master for release 0.1, so I did that. But now my <code>v0.1</code> tag is stuck on (to invoke the post-it note analogy) the wrong commit. I want it to be stuck on the most recent commit on master, but instead it is stuck on the second most recent commit on master.</p>
  
  <p>How can I move it to the most recent commit on master?</p>
