<h4>PSA: The classic WP Popular Posts widget has reached End-of-Life</h4>
The classic WP Popular Posts widget doesn’t work very well / at all with the <a href="https://wordpress.org/documentation/article/block-based-widgets-editor/" rel="ugc">block-based Widgets editor</a> introduced with WordPress 5.8.
This new Widgets editor expects <a href="https://wordpress.org/documentation/article/blocks-list/" rel="ugc">WordPress blocks</a> instead of regular WordPress widgets. If you’re using the classic WP Popular Posts widget please replace it with the <a href="https://cabrerahector.com/wordpress/wordpress-popular-posts-5-3-improved-php-8-support-retina-display-support-and-more/#block-editor-support" rel="nofollow ugc">WP Popular Posts block</a> instead – it has the same features and functionality as the “classic” widget so you won’t be missing anything at all. See the <a href="https://cabrerahector.com/wordpress/migrating-from-the-classic-popular-posts-widget/" rel="nofollow ugc">Migration Guide</a> for more details.
Bjorn from wplearninglab.com was kind enough to create a video explaining how to use the new block for all of you visual learners:

If you cannot (or do not want to) use WordPress blocks on your website then please replace your classic widget with the <a href="https://github.com/cabrerahector/wordpress-popular-posts/wiki/1.-Using-WPP-on-posts-&-pages#the-wpp-shortcode" rel="nofollow ugc">[wpp] shortcode</a>.
