Explanation:
This code snippet uses the WP_Query class to fetch all published release notes. The post_type parameter is set to 'release-note' to query only the release note post type. The post_status parameter is set to 'publish' to fetch only published release notes. The posts_per_page parameter is set to -1 to retrieve all release notes.
Inside the loop, each release note is displayed in a <div> container with its title, content, and a "Learn More" link. The the_title() and the_content() functions are used to output the title and content of each release note respectively. The the_permalink() function is used to generate the URL for the "Learn More" link.
After the loop, the wp_reset_postdata() function is called to restore the global post data to the main query. This is necessary to prevent any conflicts with other queries on the page.
If no release notes are found, the code displays a message stating "No release notes found."
You can place this code snippet in your theme's template file or in a custom shortcode or widget to display the release notes on the front end.
