“What’s new in Gutenberg…” posts (labeled with the #gutenberg-new tag) are posted following every Gutenberg release on a biweekly basis, showcasing new features included in the release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Site Editor project (formerly called Full Site Editing).
Gutenberg 15.1 has been released and is available for download!
This release sees the integration of Openverse through the Media tab, the addition of custom CSS per block via the styles sidebar and theme.json, navigation menus in the browse mode sidebar, and the facility to add shadow presets in global styles.
