This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

@primer/react@38.28.0

Minor Changes

• #788845be31b Thanks @TylerJDev! - AnchoredOverlay: Extend cssAnchorPositioningSettings with a fallbackStrategy ('default' | 'none' | 'opposite-side') to control CSS anchor positioning fallback behavior when native CSS anchor positioning is active.

• #79236a7e130 Thanks @dylanatsmith! - Card: Add layout="compact" prop for a compact card layout with tighter spacing, no icon background, and smaller title

• #792255b7b04 Thanks @dylanatsmith! - InlineMessage: Make variant prop optional, defaulting to the standard foreground color with an info icon

• #78893af5edc Thanks @llastflowers! - Add data-component attributes and associated tests for PageHeader, PageLayout, Pagehead, Popover, Portal, and ProgressBar

• #79640f0f79f Thanks @TylerJDev! - AnchoredOverlay: Add cssAnchorPositioningSettings prop to allow opting out of native CSS anchor positioning (via disable), and use it in SelectPanel so the modal variant stays manually centered instead of being repositioned by CSS anchor positioning.

Patch Changes

• #791895986ce Thanks @jonrohan! - Autocomplete: Keep the typed text instead of restoring the full inline suggestion when the input loses focus, matching the behavior of pressing Escape

• #79712087e87 Thanks @francinelucca! - ThemeProvider: Skip rendering the SSR handoff script when the primer_react_theme_provider_remove_ssr_handoff feature flag is enabled

• #79100c38cfa Thanks @janmaarten-a11y! - Timeline: Add primer_react_timeline_list_semantics feature flag to opt into list semantics

  When the primer_react_timeline_list_semantics feature flag is enabled, Timeline renders as <ol role="list"> and Timeline.Item / Timeline.Break render as <li> so screen reader users get list navigation (total item count, position in sequence). The default behavior is unchanged — Timeline and its subcomponents still render as <div> until the flag is opted into.

  Enable the flag with the FeatureFlags provider:

  import{FeatureFlags}from'@primer/react/experimental';<FeatureFlagsflags={{primer_react_timeline_list_semantics: true}}><Timeline>…</Timeline></FeatureFlags>

@primer/mcp@0.3.3

Patch Changes

• Updated dependencies [45be31b, 95986ce, 6a7e130, 55b7b04, 3af5edc, 2087e87, 0f0f79f, 0c38cfa]:
