 		Major changes since the <a href="https://www.w3.org/TR/2019/WD-css-sizing-3-20190522/">22 May 2019 Working Draft</a> include:
 
 	<ul>
-		<li>...
-		<li>Switched default sizing of an object with an intrinsic aspect ratio to use the ICB size instead of 300px&times;150px.
+		<li>
+			Defined that ''width/min-content'' and ''width/max-content''
+			do not necessarily behave the same as the property’s initial value
+			if otherwise specified (by the relevant layout module).
+			(<a href="https://github.com/w3c/csswg-drafts/issues/3973">Issue 3973</a>)
+
+		<li>
+			Switched intrinsic contribution of ''fit-content()''
+			to treat its argument as that argument would be treated alone
+			for intrinsic contribution calculations
+			and resolve the fit-content formula accordingly,
+			rather than having special behavior for ''fit-content()'' resolution
+			when calculating intrinsic contributions.
+			(<a href="https://github.com/w3c/csswg-drafts/issues/3731">Issue 3731</a>)
+
+		<li>
+			Changed the [=max-content size=] of replaced boxes
+			without an intrinsic size
+			to use their [=minimum size=] in place of ICB or 300px&times;150px
+			only when it is a <<length>>.
+			(<a href="https://github.com/w3c/csswg-drafts/issues/4217">Issue 4217</a>)
