+  * The Make Page Printable template has changed (as per bug #11857). The HTML
+    is now consistent with other default Style templates. The Plain Black logo and
+    copyright info have been removed and a stylesheet was added to provide very
+    simple default formatting for text, header and footer (makepageprintable.css).
