sidebar — the mobile collapse breakpoint is no longer hard-coded to 768px. It now reads from the project’s components config (sidebar.root.props.mobile), so each project can override the threshold without forking the component.

popover — customWidth prop renamed to fullWidth and the semantics are inverted. Before, the popover width defaulted to the configured popoverConfig.width; now it sizes to its content by default and only stretches to the configured width when fullWidth is true. Migration: drop customWidth={false} (matches the new default); replace customWidth={true} with no prop, or pass fullWidth if you want the popover to stretch to the trigger width.
select, multiselect — new fullWidth prop (non-breaking) so the listbox can stretch to the trigger.

actionbar — the hard-coded density = "compact" default has been removed; when no density prop is passed the component now derives it from the isLg breakpoint check. Migration: if you were relying on the implicit "compact" default at all sizes, pass density="compact" explicitly.
