+			  Finally, GLM 0.9.1 branch is reaching the status of stable with
+			  <link href="https://sourceforge.net/projects/ogl-math/files/glm-0.9.1.0/glm-0.9.1.0.zip/download">GLM 0.9.1.0</link>.

 		  <paragraph>
-			  The stable version, GLM 0.9.0.8, adds the operator * for quaternion products and deprecated the cross function previously used for the same purpose.
-			  Also, it clarifies that GLM is a header only library when a user try to build it. Once more, there is nothing to build.
+			  From GLM 0.9.1 beta, mainly bugs has been fixed. GLM has evolved on many sides since GLM 0.9.0:
+			  Improved documentation (manual and doxygen), better test framework, simplified setup/options/configration of GLM and new experimental SIMD API.
 		  </paragraph>
 		  <paragraph>
-			  The development version, GLM 0.9.1 beta, provides an improved <link href="http://glm.g-truc.net/html-0.9.1/index.html">API documentation</link> by

-			  author of <link href="http://www.arcsynthesis.org/gltut/">a great OpenGL tutorial</link> which uses GLM.
-			  This version also improves the SIMD extensions and it fixes many bugs.
+			  GLM 0.9.1.0 is not 100% backward compatile with

+			  but mainly advanced usages should be affected by the differencies.
