Previously, the Cover block only allowed users to add a heading, button, or paragraph block. Users had resorted to employing clunky solutions to get around the restrictions, such as using the group block with a custom class and using CSS to add backgrounds and overlay styling. The restrictions have now been removed to give users greater flexibility in styling these blocks.
Another new user-facing feature in 6.2 is the ability to customize the link target of the Button block, enabling users to designate the link to open in a new tab. Gutenberg Phase 2 lead Riad Benguella said this small improvement was a frequently requested feature.
Gutenberg 6.2 includes more than two dozen enhancements and bug fixes, along with many mobile and documentation improvements. Check out the changelog in the release post for more details.
