 	Changes since the <a href="https://www.w3.org/TR/2017/WD-css-display-3-20170720/">20 July 2017 Working Draft</a> include:
 
-	* Moved back the section about becomming a formatting context to css-contain
+	* Tightened up rules for the <a>blockification</a> of ''display/inline-block'' / ''inline flow-root''
+		to ensure compatibility with CSS2.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1246">Issue 1246</a>)
+		Updated handling of ''run-in flow-root'' to match.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1715">Issue 1715</a>)
+	* Adjusted grammar of 'display' to list the ''display/list-item'' keyword last. This affects the expected serialization order.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1621">Issue 1621</a>)
+	* Added better definition of interaction between <a>block formatting contexts</a> and <a>inline formatting contexts</a> in block containers that establish inline formatting contexts.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1553">Issue 1553</a>)
+	* More clearly defined the way property values are reflected
+		between an element and its boxes (in the case of an element generating multiple boxes).
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1643">Issue 1643</a>)
+	* Clarified that empty text objects are ignored for CSS rendering.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1808">Issue 1808</a>)
+	* Clarified that 'display' has no effect on document semantics, since this is a common bug in UAs.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/2355">Issue 2355</a>)
+	* Fixed error in definition of 'display'’s <a>computed value</a>
+		(which is definitely not “as specified”, due to <a>blockification</a> and <a>inlinification</a> rules triggered by various properties).
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1716">Issue 1716</a>)
+	* Added definition for <a>document order</a>.
+	* Added missing SVG elements to <a hrerf="#unbox">Appendix B</a>’s details on ''display: contents''.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/2118">Issue 2118</a>)
+	* Added some <a href="#box-guidance">guidance</a> to future spec authors of anonymous box construction rules.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/1643">Issue 1643</a>)
+	* Pushed the section about “becoming a formatting context” back to <a href="https://www.w3.org/TR/css-contain-1/">CSS Containment</a> where it is used.
+	* Various minor wording fixes and clarifications.
