 *              `div` tags to `dl`, `dt` and `dd` tags. Support more than one gallery on the
 *              same page.
 * @since 2.9.0 Added support for `include` and `exclude` to shortcode.
 * @since 3.5.0 Use get_post() instead of global `$post`. Handle mapping of `ids` to `include`
 *              and `orderby`.
 * @since 3.6.0 Added validation for tags used in gallery shortcode. Add orientation information to items.
 * @since 3.7.0 Introduced the `link` attribute.
 * @since 3.9.0 `html5` gallery support, accepting 'itemtag', 'icontag', and 'captiontag' attributes.
 * @since 4.0.0 Removed use of `extract()`.
 * @since 4.1.0 Added attribute to `wp_get_attachment_link()` to output `aria-describedby`.
 * @since 4.2.0 Passed the shortcode instance ID to `post_gallery` and `post_playlist` filters.
 * @since 4.6.0 Standardized filter docs to match documentation standards for PHP.
 * @since 5.1.0 Code cleanup for WPCS 1.0.0 coding standards.
 * @since 5.3.0 Saved progress of intermediate image creation after upload.
 * @since 5.5.0 Ensured that galleries can be output as a list of links in feeds.
