@primer/react@38.46.0

Minor Changes

• #8592 0ae18d3 Thanks @liuliu-dev! - Card: Add optional shadows, regular (16px) and spacious (24px) padding in either layout, and heading links and buttons with opt-in full-card hit areas using fullCardHitArea. Existing normal padding and defaults are unchanged.

• #8692 918d7cf Thanks @copilot-swe-agent! - Stack: Add balance as a value for the wrap prop.

Patch Changes

• #8748 324b0aa Thanks @mattcosta7! - Breadcrumbs: Collapse crumbs that render more than one element (such as a link with a sibling button) when they no longer fit, instead of overflowing the container.

• #8683 32d5061 Thanks @mattcosta7! - Breadcrumbs: Improve the performance of overflow="menu" and "menu-with-root" on mount, resize and navigation. Server-rendered markup now applies the collapse rules before hydration, and the overflow menu trigger is a <button>.

• #8592 0ae18d3 Thanks @liuliu-dev! - Card: Improve shrinking and equal-height layouts, keep secondary controls accessible in custom whole-card compositions, and keep images edge-to-edge across padding options.

• #8679 dbf2ac1 Thanks @llastflowers! - Breadcrumbs: Close the overflow menu when Escape is pressed while its tooltip is open.

• #8628 41f29c8 Thanks @joshblack! - SkeletonAvatar, SkeletonText: Preserve the requested size and shape regardless of stylesheet load order

• #8681 8a9013e Thanks @mattcosta7! - SkeletonBox, SkeletonText, SkeletonAvatar, ProgressBar: Run the loading shimmer animation on the compositor to reduce main-thread work while skeletons are visible

• #8562 ee46232 Thanks @joshblack! - useOnEscapePress, useOnOutsideClick: Improve performance when callbacks change between renders.

• #8609 da90227 Thanks @tay1orjones! - ActionList.LinkItem, NavList.Item: Preserve keyboard focus and running child animations when links rerender.

• #8684 35ff497 Thanks @mattcosta7! - TreeView: Reduce mount and hydration cost for large trees. Server-rendered trees now have a single tab stop and named subtrees before hydration.
