Full-Site-Editing (FSE) is the umbrella term in WordPress, under which numerous functions can be found that affect the editor and thus the editing of pages. The new version 5.8, which is available immediately, brings even more blocks with it. These enable access to more areas of a page without the need for knowledge of the code, and come under FSE.
The update called Tatum (named after Art Tatum, a jazz pianist) comes with new blocks that are needed for building templates and template parts – for keywords, author and categories, for example. You can choose to deal with content for pages or post types. Editing the templates also results in an update of previously existing content. WordPress writes in the blog post that the innovation should be a “more complex Latest Post Block” that shows past posts. Blocks for widgets and the customizer, with which the layout is designed, are also new. This opens up new possibilities for developers to create content – “from no-code mini layouts to large libraries of core and third-party blocks”.
Support for WebP and no support for IE11
The new duotone block is located under the cover and picture blocks. This works like a black and white filter, which is then enriched with color. All innovations are already available in WordPress as beta and release candidates. It was also clear that version 5.8 supports the WebP graphic format; it produces smaller files than JPEG and PNG with the same quality.
The Global Styles and Global Settings APIs are available to developers. Here you can make settings on the editor via Theme.json, and adapt the design and other options more easily than before. WordPress has its own blog post with explanations.
Internet Explorer 11 is no longer supported for this. “If you use IE11, we strongly recommend upgrading to a more modern browser.” For the upcoming version of WordPress it is planned to offer whole themes based on blocks.
