Freshen up the look of the quote, verse, and post content blocks using the new background image feature.

Previously, options for background images were limited to container blocks like the Cover and Group blocks, but with the feature now supported across several blocks, it’s easier for users to attain the look they want without nesting blocks.

DataViews: Extensibilty APIs

Very early work on extensibility for DataViews was shipped in this release.

‘DataViews’ is the component that powers the post listing views available in the Site Editor, and in the future will become an important part of the new adminadmin (and super admin) design project.

The APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. being explored will allow the registration of actions for different ‘entities’ (post types and other types of data represented by the listings). Right now, the API is private to the Gutenberg PluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party and will undergo further development and testing before being made public for third parties.
