+2009-07-30: Version 1.3.1
+
+        Speed improvements to accessors and interceptors.
+
+        Added support for capturing stack information on custom errors.
+
+        Added support for morphing an object into a pixel array where its
+        indexed properties are stored in an external byte array. Values written
+        are always clamped to the 0..255 interval.
+
+        Profiler on x64 now handles C/C++ functions from shared libraries.
+
+        Changed the debugger to avoid stepping into function.call/apply if the
+        function is a built-in.
+
+        Initial implementation of constructor heap profile for JS objects.
+                  
+        More fine grained control of profiling aspects through the API.
+                    
+        Optimized the called as constructor check for API calls.

 2009-07-27: Version 1.3.0
