+  New in JsonCpp 0.6.0:
+  ---------------------
+
+* Compilation
+
+  - LD_LIBRARY_PATH and LIBRARY_PATH environment variables are now propagated to the build
+    environment as this is required for some compiler installation.
+
+  - Added support for Microsoft Visual Studio 2008 (bug #2930462): 
+    The platform "msvc90" has been added.
+
+    Notes: you need to setup the environment by running vcvars32.bat 
+    (e.g. MSVC 2008 command prompt in start menu) before running scons.
