[dependabot]

Bumps @wordpress/block-library from 10.3.0 to 10.4.0.

Changelog

Sourced from @​wordpress/block-library's changelog.

10.4.0 (2026-08-12)

Internal

• Embed: Use the new @wordpress/kebab-case package instead of unlocking the kebabCase utility from the @wordpress/components private APIs (#81294).

Enhancements

• Playlist Track: Use a dedicated icon for the block toolbar. (#80959)
• Playlist: Expose the parent "Add track" toolbar control to selected Playlist Track child blocks via block toolbar sharing (#80368).
• Playlist: Allow selecting audio tracks individually in the Media Library without holding Shift or Command, transform multiple Audio blocks into a Playlist, and transform a one-track Playlist into Audio. (#80926)
• Page List: Rename the "Edit" action to "Detach", and confirm it in a dialog explaining that the list will keep its current pages but stop adding new ones automatically, matching the Gallery block (#80847).
• Tabs: Start new tabs with an empty label showing a "Tab title" placeholder instead of a generic "Tab" (#81009).
• Tab Panel: Show the tab's title in the Document Overview instead of the generic block title, so tabs can be told apart (#81427).

Bug Fixes

• Footnotes: Treat unreadable footnotes post meta as no footnotes instead of throwing, so the block shows its placeholder rather than the block crash warning (#81201).
• Playlist Track: Show the upload loading indicator inline with the track row.
• Playlist: Improve handling of declarative waveform player configuration (#81342).
• Playlist: Update @arraypress/waveform-player to ^1.26.0, disable automatic initialization, and prevent custom SVG icons from being configured through HTML data attributes.
• Cover: Pass 'full' instead of null as the featured image size for parallax and repeated backgrounds, so a null array offset is no longer reached on PHP 8.5 (#81444).

Internal

• Details: Import withIgnoreIMEEvents from @wordpress/keycodes instead of unlocking it from @wordpress/components (#81343).
