 	<ul>
-		<li>
+		<li>Applied 'align-content' and 'justify-content' to the <a>grid tracks</a> rather than to the <a>grid</a> as a monolithic unit, to allow justification of grid items across the grid container.
+		<li>Removed <css>stack</css> value from 'grid-auto-flow'.
+		<li>Added ''auto'' keyword to ''repeat()'' function for auto-filled tracks.
+		<li>Fixed handling of row-locked auto-placed items to correctly place sparsely.
+		<li>Ported special handling of fractional flex values from Flex Layout to Grid Layout.
+		<li>Fixed error in resolution of intrinsic track sizes that resulted in infinite growth limits.
+		<li>Defined error handling for too-large grids, placement conflicts, and missing named lines.
+		<li>Clarified handling of orthogonal flows, sizing of grid containers, and sizing of grid items.
+		<li>Various other layout clarifications and fixes.
