 The following changes were made since the <a href="http://www.w3.org/TR/2014/WD-geometry-1-20140918/">18 September 2014 Working Draft</a>.
 
 <ul>
+  <li>Changed {{DOMMatrixReadOnly}} and {{DOMMatrix}} to be compatible with
+  <code>WebKitCSSMatrix</code>:
+    <ul>
+      <li>Changed <a>rotate()</a> and <a>rotateSelf()</a> arguments from (angle, originX, originY)
+      to (rotX, rotY, rotZ).
+
+      <li>Changed the <a>scale()</a> and <a>scaleSelf()</a> methods to be more like the previous
+      <code>scaleNonUniform()</code>/<code>scaleNonUniformSelf()</code> methods, and dropped the
+      <code>scaleNonUniform*</code> methods.
+
+      <li>Made all arguments optional for {{DOMMatrix}}/{{DOMMatrixReadOnly}} methods, except for
+      <a>setMatrixValue()</a>.
+
+      <li>Changed <code>fromString()</code> static method to overloaded constructor.
+
+      <li>Added no-argument constructor.
+
+      <li>Defined <code>window.WebKitCSSMatrix</code> to alias {{DOMMatrix}}.
+    </ul>
   <li>Exposed <a interface>DOMPointReadOnly</a>, <a interface>DOMPoint</a>, <a interface>DOMRectReadOnly</a>, <a interface>DOMRect</a>, <a interface>DOMQuad</a>, <a interface>DOMMatrixReadOnly</a> and <a interface>DOMMatrix</a> to <code>Window</code> and <code>Worker</code>. Defined cloning of the interfaces.</li>
   <li>The live <code>bounds</code> attribute on {{DOMQuad}} was replaced with a non-live {{DOMQuad/getBounds()}} method. The "associated bounding rectangle" concept was also removed.
 </ul>
