Key features delivered include: 1) Title component enhancements with the withDivider prop to hide the default separator, plus CSS/React/docs/tests updates and a container-based margin refactor with consistent BEM naming (commits e9a44a691f..., 08c66ef6dd56...). 2) Design system styling refinements, notably updating the Table header background to align with design system variables and refinements to ghost/ghost-reverse button variants (icon sizing, padding and spacing) (commits 5f80bbdf5696..., 8ed551708bed...). 3) Timeline component layout and docs improvements with grid-based spacing for responsiveness and updated Storybook data/docs for timeline dates (commit a08fe48a7576...). Major fixes included correcting Title bottom margin and timeline spacing/documentation regressions (corresponding fix commits 08c66ef6dd56... and a08fe48a7576...).
