+### shortcodes
+
+We've made some changes to [the Gist shortcode](https://en.support.wordpress.com/gist/) in this release. It should now be fully compatible with the AMP plugin.
+
+To test this, try installing the AMP plugin on your site (either the current Stable version or [the Beta](https://github.com/Automattic/amp-wp/releases/tag/1.0-RC1-built)), and try adding Gists, using different formats, to one of your posts. Here are some examples:
