 Changes</h2>
 
-	The following significant changes were made since the
-	<a href=https://www.w3.org/TR/2015/WD-css-grid-1-20150806/>6 August 2015 Working Draft</a>.
-
-	* Renamed <css>row-gap</css>/<css>column-gap</css> to 'grid-row-gap'/'grid-column-gap'
-		to avoid having multicol and grid share 'column-gap'.
-		This also preserves <css>grid-</css> as a prefix across these properties and their shorthand.
-	* Split ''auto'' into ''auto-fill'' and ''auto-fit'' keywords for ''repeat()'' notation,
-		adjusted grammar to guarantee a definite number of repetitions,
-		and allowed minimum sizes to increase the number of repetitions past one to fulfill the minimum.
-	* Reduced <<auto-repeat>> syntax to accept only a single track size, for simplicity.
-	* Added information on the speech and navigation impact of reordering with grid placement or 'order'
-		vs. reordering the underlying source.
-	* Removed <css>grid-template</css> shorthand.
-
-	A partial <a href="https://drafts.csswg.org/css-grid-1/issues-wd-20150805">Disposition of Comments</a> is available.

+	<ul>
+		<li>
+			Internal table cell display types are <a>blockified</a>
+			instead of wrapped in an anonymous table.
+			(Updated to match changes to <a href="http://www.w3.org/TR/css-flexbox-1/">Flexbox</a>.)
+		<li>
+			Added <a href="#item-margins"></a>
+			and undefined whether percentages are calculated
+			against the block or inline axis of grid item’s containing block.
+		<li>
+			Added <a href="#order-accessibility"></a>
+		<li>
+			Fixed incorrect “Animation” lines in the property definition tables.
+		<li>
+			Allow <<fixed-size>> to accept ''minmax()'' notation.
+		<li>
+			Disallow <<flex>> sizes as minimum of ''minmax()'' function.
+			(Plan to allow it later, once we figure out how to make it work
+			in a manner consistent with <a href="https://lists.w3.org/Archives/Public/www-style/2016Mar/0333.html">author expectations</a>)
+		<li>
+			Fix errors and add clarifications to <a href="#auto-repeat">auto-repeat</a> definition.
+		<li>
+			Fix handling of assumed names of <a>implicit grid lines</a>
+			to account for the “search direction”.
+		<li>
+			Added back error handling for when the start and end lines are identical.
+		<li>
+			Corrected errors in finding the size of the implicit grid
+			in the <a>placement algorithm</a>.
+		<li>
+			Auto-place into the <a>implicit grid</a> rather than the <a>explicit grid</a>.
+		<li>
+			Don't follow ''auto'' values of 'align-self' or 'justify-self'
+			on absolutely-positioned children;
+			just default to ''start'' alignment.
+			(Properties set on the grid container
+			usually aren't meant to affect absolutely-positioned children.)
+		<li>
+			Clarify that negative gutters are invalid.
+		<li>
+			Specify that gutters are omitted at fragmentation breaks.
+		<li>
+			Define location of a <a>grid line</a> when ther eare no <a>grid tracks</a>.
+		<li>
+			Correct sizing of the grid under
+			a <a lt="min-content constraint">min-content</a> or <a>max-content constraint</a>.
+		<li>
+			Allow 'max-width'/'max-height' to affect track sizing in a sensible way.
+		<li>
+			Allow fragmentation breaks between grid columns.
+		<li>
+			Various editorial improvements.
