material 3.0.4

Fixed

• A tooltip's arrow is the colour of the tooltip's own surface, in every variant and both
  themes (#77).
  The arrow grows out of the container, so it has to read as that surface. A rich tooltip paints
  surface-container, but its arrow kept the base inverse-surface; a plain tooltip paints
  inverse-surface, but its arrow still painted the surface-container-high of a surface the
  variant had dropped. On each of the twelve placements that draw an arrow, the arrow showed as a
  triangle in a colour that was not the tooltip's own. Every direction now takes its colour from
  the variant's surface — inverse-surface by default and for plain, surface-container for rich.
  Geometry, transitions and the surfaces themselves are unchanged.

• An uncontained carousel lays every item out at the configured item size, stepping by
  itemWidth + gap and flowing past the container's edge (#78).
  The uncontained layout was placed through the multi-browse keyline model: after the first one or
  two items, slides were scaled down toward a 10 px anchor, so each showed as a sliver a few pixels
  wide and consecutive items stepped 28.8 px apart instead of 288. That bunched the tail of the row
  into a fraction of its width and left the row ending well before the container's right edge.
  Items are now laid out at the configured width, at itemWidth + gap steps, and cut only by the
  container edge — never shrunk into a sliver. How much of an item the edge leaves showing depends
  on the container width and the scroll position. An item that sits fully past the edge stays laid
  out and is not hidden. Snap positions are those steps, so a slide's scroll offset is its index
  times itemWidth + gap; the scrollable extent is wider, because the row is now as long as its
  slides. The contained variants — multi-browse, hero, center-aligned hero and fullscreen — keep
  their keyline layout, and under reduced motion they behave as before.
