Breakdance 3.0 Beta 4 is available for testing and includes fixes for issues reported during the 3.0 beta period. For comprehensive details on version 3.0, see the Beta 1 announcement.
Builder
- Breakdance Doctor: broken data used to stop a page from opening in the builder. Now, the Doctor automatically repairs the page and shows you exactly what it fixed.
- Accessibility: the builder’s toolbar buttons, panel headers, properties panel tabs and accordions, popout openers, Add panel tiles, and the Structure panel tree now expose proper ARIA roles and labels. Screen readers get a real accessibility tree, and AI agents driving the builder can find controls by name instead of clicking coordinates
Gutenberg
- Blocks migrated to apiVersion 3: the Breakdance launcher and Global Block blocks are now compatible with the WordPress 6.9 iframe editor.
- Breakdance Zero theme now ships editor styles, so Gutenberg matches the theme instead of defaulting to a serif font
MCP Server
- New preview-global-settings-css tool lets agents inspect the CSS generated from global settings
- insert-stylesheet now replaces a selector’s properties per breakpoint: importing a
@media rule for an existing selector no longer wipes the selector’s base properties
- insert-stylesheet and html-to-page now warn when an imported CSS rule drops properties a selector already had, listing the selector, breakpoint, and exactly which properties went missing
- edit-post now validates dynamic data bindings, and malformed dynamic data are rejected with a clear error instead of silently rendering nothing
- set-template-conditions gained a
disabled flag, so agents can enable or disable an existing template
- The CSS importer now classifies modern color functions (
oklch(), lab(), color-mix(), and friends) as color variables
@supports was never officially supported by the CSS importer; it’s now disabled with a warning instead of being preserved verbatim, and may be revisited in the future- Loop guidance now tells agents to never set a custom query on an archive template’s primary loop, because custom queries break archive pagination
Bug Fixes
- Fundamental Image no longer drops custom alt text when the image source is set to URL
