LGTM

Using only the major version number is the correct implementation (as @aemmadi has done). This will load the latest v4 minor and point releases, but not the next major release (v5).

Two change requests:

1. Remove the file path and name from the URL:

   <script src="//cdn.jsdelivr.net/npm/docsify@4"></script>

   JSDelivr will automatically deliver the file specified in package.json using the jsdelivr, browser or main property and minify it if necessary. Docsify specifies "main": "lib/docsify.js" in its package.json file, so specifying only //cdn.jsdelivr.net/npm/docsify@4 will result in the minified version of lib/docsify.js being delivered. The reason to do this is because it gives maintainers the ability to change the file location of the main file without requiring an update to the CDN URL. If interested, you can read more about it here: https://www.jsdelivr.com/features#publishing-packages

2. Add a docsify version to the stylesheet as well

   docsify-cli/lib/template/index.html

   Line 9 in 22314d3

   <link rel="stylesheet" href="//cdn.jsdelivr.net/npm/docsify/lib/themes/vue.css">

   Should be:

   <link rel="stylesheet" href="//cdn.jsdelivr.net/npm/docsify@4/lib/themes/vue.css">

   Note here that, unlike above, the full URL (path and filename) are required. This is because only one default file can be specified in package.json.

These same changes should be made in docsifyjs/docsify#1225.

Looks good!
