title: What is the difference between Continuous deployment trigger and Pull request trigger?
body: <p>Azure DevOps Release pipeline artifact settings has 2 options:</p>
  
  <ol>
  <li>Continuous deployment trigger - Enabling the trigger will create a new release every time <strong>a new build is available</strong>.</li>
  <li>Pull request trigger - Enabling this will create a release every time a <strong>selected artifact is available</strong> as part of a pull request workflow</li>
  </ol>
  
  <p>I am trying to understand what is the difference between these options with respect to the highlighted parts and whether the build validation policy causes release to trigger with both options, if so then why do we have pull request trigger?</p>
