 	Changes since the <a href="https://www.w3.org/TR/2016/WD-css-align-3-20160614/">previous Working Draft</a> include:
 
+	* Add shorthands.
+	* Drop fallback alignments, because they interfere with shorthanding.
+		(Alternative syntaxes for the functionality are under investigation.)
 	* Make ''align-self/auto'' values of 'align-self' and 'justify-self' compute to themselves.
+	* Rework baseline alignment rules wrt synthesizing baselines; drop concept of block-axis baseline propagation.
 	* Use the intrinsic size on grid items with an intrinsic aspect ratio so that we honor their aspect ratio by default (i.e. when 'align-self' and 'justify-self' are ''align-self/normal'').
+	* Fix Applies-to errors.
+	* Handle baselines of scroll containers per CSS2.1 errata; mark as an issue.
+	* Apply 'justify-content' to column boxes in multi-column elements.
+	* Drop hyphen in first/last baseline alignment keywords in order to avoid combinatorial explosion in related properties for inline alignment.
+	* Miscellaneous fixes and clarifications. See <a href="https://hg.csswg.org/drafts/log/tip/css-align/Overview.bs">detailed history</a>.
