+        <dd>
+          <ul>

+            <li>Fixed the location of prebuilt STLport binaries in the NDK release package.
+            A bug in the packaging script placed them in the wrong location.</li>
+            <li>Fixed <code>atexit()</code> usage in shared libraries with the x86standalone
+            toolchain.</li>
+            <li>Fixed <code>make-standalone-toolchain.sh --arch=x86</code>. It used to fail
+            to copy the proper GNU libstdc++ binaries to the right location.</li>
+            <li>Fixed the standalone toolchain linker warnings about missing the definition and
+            size for the <code>__dso_handle</code> symbol (ARM only).</li>
+            <li>Fixed the inclusion order of <code>$(SYSROOT)/usr/include</code> for x86 builds.
+            See the <a href="http://code.google.com/p/android/issues/detail?id=18540">bug</a> for
+            more information.</li>
+            <li>Fixed the definitions of <code>ptrdiff_t</code> and <code>size_t</code> in
