Add ‘advanced app bar‘ CSS. This component is not an extension of the existing app bar but a new component with more possibilities for structure and customization.
Add ‘double arrow‘ icons in regular and bold weight.
Add icon-only ‘split button‘.
Changed
Add support for multiple buttons in empty state area.
Adapt button group coloring to comply with specs.
Update theming examples to use the advanced app bar (and document necessary color variables).
Remove fixed font-size in ‘paragraph‘ and ‘small paragraph‘ elements and corresponding classes since they don’t align with text in non-typographic markup such as divs, spans etc.
