“What’s new in GutenbergGutenbergThe Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc.
https://wordpress.org/gutenberg/…” posts (labeled with the #gutenberg-new tag) are posted following every Gutenberg release on a biweekly basis, showcasing new features included in each release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Editor.
This release introduces responsive global blockBlockBlock is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. styles with states, brings further improvements to the experimental Content Types management screens, and adds a wave of accessibilityAccessibilityAccessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers). (https://en.wikipedia.org/wiki/Accessibility) refinements to the RevisionsRevisionsThe WordPress revisions system stores a record of each saved draft or published update. The revision system allows you to see what changes were made in each revision by dragging a slider (or using the Next/Previous buttons). The display indicates what has changed in each revision. interface. The @wordpress/ui package gains a new SelectControl and motion design tokens, while modals now render as bottom sheets on mobile. Other changes include shortcodeShortcodeA shortcode is a placeholder used within a WordPress post, page, or widget to insert a form or function generated by a plugin in a specific location on your site.-to-block transforms, Grid component enhancements, Connectors refinements, and continued Real-time Collaboration reliability fixes.
You can now customize how individual blocks look on different screen sizes, right from Global Styles.
Head to Global Styles → Blocks, and you’ll find a new States dropdown on each block with Tablet and Mobile options. Select a state, make your style changes, and they’ll apply only to that breakpoint.
This allows theme developers and site builders to define different block styles depending on viewport size and interaction state, paving the way for more adaptive designs managed entirely through the editor. (#77513)
Add motion design tokens (duration and easing) to wordpress/theme
Adds motion design tokens to @wordpress/theme — a set of duration and easing curve tokens for standardizing animation timing across components — and adopts them in Dialog, Modal, and Menu/DropdownMenu.
Modal renders as a bottom sheet on mobile
The Modal component now adapts to narrow viewports by rendering as a bottom sheet, providing a more touch-friendly experience on phones and small tablets. (#77956)
With the new position, important actions are easier to reach with one hand.
Other Notable Highlights
Content Types management improvements (experimental): The experimental Content Types screens are extended with several refinements: taxonomyTaxonomyA taxonomy is a way to group things together. In WordPress, some common taxonomies are category, link, tag, or post format. https://codex.wordpress.org/Taxonomies#Default_Taxonomies. visibility fields let you control where taxonomies appear (#77835), slugs are now auto-filled from the singular label (#77938), and new term/post type count fields provide an at-a-glance view of content usage (#78157). Additional quality-of-life actions—duplicate, view, and quick-edit—round out the management experience.
SelectControl added to @wordpress/ui. A new SelectControl primitive joins the design-system package, offering a consistent select input across the editor and adminadmin(and super admin) surfaces. (#77809)
Shortcode-to-block transforms. The Embed block now recognizes [ embed ] shortcodes (#77937), and the Shortcode block offers block-specific transforms when the text matches a registered shortcode (#77944).
Grid component improvements. The @wordpress/grid package gains a renderResizeHandle render prop (#77811), an edit-mode overlay for DashboardGrid and DashboardLanes (#78199), document cursor lock during resize (#77813), and resize-runaway prevention near the viewport edge (#77854).
Revisions accessibility improvements. Diff markers now enforce a 24×24 px minimum target size per WCAGWCAGWCAG is an acronym for Web Content Accessibility Guidelines. These guidelines are helping make sure the internet is accessible to all people no matter how they would need to access the internet (screen-reader, keyboard only, etc) https://www.w3.org/TR/WCAG21/. 2.5.8 (#77671), use diagonal stripe patterns to avoid color-only distinction (#77904), and display tooltips (#77690). The revisions slider now paginates by 100 per page for better performance (#77200).
Real-time Collaboration reliability fixes. Title divergence between users on page refresh has been resolved (#77666), a race condition on room creation that could split the update log is fixed (#77675), and find_canonical_storage_post_id() no longer returns null incorrectly (#78053).
Connectors refinements.PluginPluginA 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. registration now supports an is_active callback (#77897), settings are only auto-registered when the referenced plugin is actually installed and active (#77273), and the Connectors page works on read-only file systems (#77521).
