What is included in the WordPress update?

The WordPress update “Tatum” to version 5.8 has been available for download since July 20, 2021. This WordPress update includes many new features, fixes 196 bugs and contains 95 extensions. In addition, from version 5.8 widgets become blocks, receive new editing views and can now be used freely in terms of content, but conversely all blocks in the areas for widgets can now be used.

We therefore recommend prompt installation of the WordPress update, but at the same time point out that the existing plug-ins and third-party tools are checked carefully. It may be useful to contact the plug-in provider/manufacturer if you are unsure.


This WordPress update is named after Art Tatum, an American jazz musician and piano virtuoso born on October 13, 1909 in Toledo, Ohio.

What’s new in WordPress 5.8 – “Tatum”?


Starting with version 5.8, widgets become blocks, which allows not only to use widgets in content, but also to use blocks in widget areas. To make this possible, views for widget editing were created and also adjusted in the Customizer. This functionality can be switched off using the “Classis Widgets” plugin.

With the new “Query Loop Block” it is possible to display a list of posts. Here you can filter by content type, categories, keywords, author and keyword. The difference to the “Recent posts block” here is that the list items themselves consist of blocks.

The new “Template Editor” allows you to edit post templates. In this way, the post can be composed of blocks in a template.

The new “Duotone Filter” enables coloring of the images and the “Cover Block”. Two colors can be chosen freely.

As of version 5.8, Internet Explorer 11 is no longer supported in the backend. Switching to the latest browser is strongly recommended here.
