-	The following significant changes were made since the
-	<a href=http://www.w3.org/TR/2014/WD-css-grid-1-20140513/>13 May 2014 Working Draft</a>.
-
-	<ul>
-		<li>Added first draft of grid container <a href="#pagination">fragmenting rules</a>.
-		<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>Changed definition of ''auto'' track sizes to look at the 'min-width'/'max-width' properties
-		    instead of always using the min-content size.
-		<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>Fixed error in resolution of intrinsic track sizes that resulted in infinite growth limits.
-		<li>Enforced <a>growth limit</a> >= <a>base size</a> throughout the <a>track sizing algorithm</a>.
-		<li>Various other layout clarifications and fixes.
-	</ul>
+	* Applied 'min-width'/'min-height' ''min-width/auto'' behavior to grid items,
+		redefined what ''grid-template-rows/auto'' means as a track size.
+	* Defined absolutely-positioned grid item placement error cases.
+	* Changed grid placement conflict handling to swap mis-assigned lines
+		instead of ignoring the end value.
+	* Use placement to find static position when grid item is both parent and containing block.
+	* Make ''repeat(auto)'' honor 'max-width'/'max-height'.
+	* Specify that only ''grid-template-rows/auto''-sized tracks are stretched by ''justify-content/stretch''.
+	* Defined <a>grid formatting context</a>.
+	* Defined that grid containers don't provide a <a>first formatted line</a>.
+	* Defined that grid containers always have at least one grid line,
+		to give placement a starting point.
+	* Clarified the term <a>implicit grid</a> and defined <a>implicit grid line</a>
+	* Miscellaneous small fixes and clarifications.
