What’s new in Gutenberg? (28 August)

With the date of the WordPress 5.3 beta release approaching, testing Gutenberg is increasingly more critical. Any help testing the plugin is much appreciated as it may avoid bugs in a future WordPress beta release.

The Gutenberg 6.4 release brings some interesting highlights.

The Cover block got two new significant functionalities: the ability to be resized and the ability to use a solid color as a background instead of a video or an image.

Recently we added an API that allows themes and plugin developers to create block styles using just PHP calls. In this release, we continued the improvements to the block styles and added the ability for the users to select their preferred default style per block. Each time the user inserts a block, the preferred style is automatically applied.

Another relevant improvement in this release is the introduction of the “Typewriter experience“. We hope this makes writing more “fun” and overall more comfortable, especially on mobile.
