-	* Switched initial values to <css>normal</css> instead of <css>auto</css>.
-	* Renamed <css>true</css> to ''unsafe'' and made it the default in all layout modes.
-	* Fixed handling of ''justify-self: stretch'' (and 'align-self') to allow shrinking, as defined in Flexbox.
-	* Made justify/align-content:auto compute to their respective behaviors for flex and grid containers,
-		and fixed other computation / “behaves as” situations.
-	* Various bugfixes and editorial improvements.
+	* Make ''auto'' values of 'align-self' and 'justify-self' compute to themselves.
