title: Autodesk Forge Viewer v7: MarkupsCore Extension
body: <p>I couldn't find any documentation for <strong>MarkupsCore</strong> Extension for the <strong>Viewer v7</strong> from <a href="https://forge.autodesk.com/en/docs/viewer/v7/developers_guide/overview/" rel="nofollow noreferrer">here</a>.</p>
  <p>Is there any reason or did I miss something?</p>
  <p>I want to know can I refer to previous versions documentation even if I'm using the Viewer v7?</p>
