   <strong>Things That Are Unstable</strong>
   Since implementation of parts of this module is effectively required
-  for shipping an implementation of CSS Writing Modes on the Web
+  for shipping an implementation of <a href="https://www.w3.org/TR/css-writing-modes-3/CSS Writing Modes</a> on the Web
   (in order to correctly implement the default HTML styles),
   The CSSWG resolved that although the draft is not very stable overall,
   the requisite features in
   <a href="#directional-keywords"></a> and <a href="#box"></a>
   are approved for shipping.
-  However, there are a number of unstable features in this draft
-  (which are not required for implementing the HTML default style sheet, incidentally),
-  and these are:
+  However, there are a few significant open issues:
   <ul>
-    <li><del>The 'float' and 'clear' keywords,
-        because it is not yet clear what the upcoming 2-dimensional syntax of 'float' will be.</del>
-        (This has been resolved as of April 2017.)
-    <li><del>The 'inset-*' properties,
-        because the name of the prefix is undecided.
-        (It used to be 'offset-*', but ended up conflicting with another CSS feature.)</del>
-        (This has been resolved as of June 2017.)
     <li>The ''border/logical'' keyword on shorthands,
         because the name of the keyword may change or it may be replaced by some other syntactic marker.
-    <li>The 'background-image-transform' and 'border-image-transform' properties,
-        because they have, as far as the editor is aware,
-        received no review from anyone and may or may not be well-designed.
+        (This feature will be deferred from this level for further development
+        if there is no clearly satisfactory mechanism proposed,
+        see <a href="https://github.com/w3c/csswg-drafts/issues/1282">Issue 1282</a>.)
+    <li>Whether flow-relative longhands inherit from their namesake on the parent,
+        or are mapped to a physical property and inherit from that property.
+        (See <a href="https://github.com/w3c/csswg-drafts/issues/3029">Issue 3029</a>.)
+    <li>Whether shorthands like 'margin' expand to both sets of longhands,
+        or only the ones that were set.
+        (See <a href="https://github.com/w3c/csswg-drafts/issues/3030">Issue 3030</a>.)
