+<h1>Mesa 10.1.3 Release Notes / (May 9, 2014)</h1>
+
+<p>
+Mesa 10.1.3 is a bug fix release which fixes bugs found since the 10.1.2 release.
+</p>
+
+<p>
+Note: Mesa 10.1.3 is being released sooner than originally scheduled to make
+available a fix for a performance rgression that was inadvertently introduced
+to Mesa 10.1.2. The performance regression is reported to make vmware
+swapbuffers fall back to software. 
+</p>
+
+<p>
+Mesa 10.1.3 implements the OpenGL 3.3 API, but the version reported by
+glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
+glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 3.3.  OpenGL
+3.3 is <strong>only</strong> available if requested at context creation
+because compatibility contexts are not supported.
+</p>

 <h2>Changes</h2>
 
 <ul>
+<li>Renamed <i>--with-llvm-shared-libs</i> to <i>--enable-llvm-shared-libs</i></li>
+<p>
+The option is used to control how mesa is linked against LLVM, and now
+defaults to enabled (shared linking).
+</p>
+
+<li>Split <i>libxatracker.so</i> into a standalone library which can be used
+with any gallium driver.</li>
+<p>
+Previously the library was linked statically against vmware's virtual gpu
+driver(svga), whereas now it loads a shared pipe_*.so driver. Provide the
+following options during configure, if you would like support for svga driver
+<i>--enable-xa --with-gallium-drivers=svga</i>
+</p>
+
+<p>
+Note: The files are installed in $(libdir)/gallium-pipe/ and the interface
+between them and libxatracker.so is <strong>not</strong> stable.
