 == New Experimental Features ==
 
- * `hg diff` now takes an experimental `--merge` flag which causes `hg
-    diff --change` to show the changes relative to an automerge for
-    merge changesets. This makes it easier to detect and review manual
-    changes performed in merge changesets.
+ * There's a new `diff.merge` config option to show the changes
+    relative to an automerge for merge changesets. This makes it
+    easier to detect and review manual changes performed in merge
+    changesets. It is only supported by `hg diff --change` so far.
