-	* Require end-edge [=padding=] to be included

-		this was previously optional for [=block containers=] with ''align-content/normal'' [=content distribution=],
-		pending Web-compatibility investigations.
-		(<a href="https://github.com/w3c/csswg-drafts/issues/129#issuecomment-1113489051">Issue 129</a>)
-	* More precisely define the interaction of '-webkit-line-clamp'
-		and the various 'line-clamp' longhands. See [[css-overflow-4#webkit-line-clamp]].
-		(<a href="https://github.com/w3c/csswg-drafts/issues/6842">Issue 6842</a>)
-	* Clarified that [=region breaks=] are what trigger discarding of subsequent content
-		for ''continue: discard'' (and that other types of breaks do not);
-		and gave examples of what triggers a [=region break=] on such a box.
-	* Minor clarifications:
-		* Annotate <<length-percentage>> value definitions using [=CSS bracketed range notation=].
