ChangeLog

@@ -1,3 +1,80 @@
+2014-10-02: Version 3.30.2
+
+        Fix Hydrogen's BuildStore() (Chromium issue 417508).
+
+        Move unit tests to test/unittests (issue 3489).
+
+        Changes to ALLOW_UNUSED to match upcoming changes to the Chromium trunk:
+        * Eliminate usage of ALLOW_UNUSED to define COMPILE_ASSERT and just use
+        static_assert() in all cases now that all platforms build with C++11. *
+        Convert remaining uses of ALLOW_UNUSED to ALLOW_UNUSED_TYPE to match how
+        Chromium will be splitting this functionality.  (In Chromium we'll have
+        both   ALLOW_UNUSED_TYPE and ALLOW_UNUSED_LOCAL, which have different
+        syntax to   enable us to use these with MSVC.) (Chromium issue 81439).
+
+        Performance and stability improvements on all platforms.
+
+
+2014-10-01: Version 3.30.1
+
+        Introduce PromiseRejectCallback (issue 3093).
+
+        ES6: Implement object literal property shorthand (issue 3584).
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-30: Version 3.29.93
+
+        Add a getter for the address and size of the code range to the pulic API
+        (issue 3598).
+
+        Convert `obj` ToObject in Object.keys() (issue 3587).
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-29: Version 3.29.92
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-26: Version 3.29.91
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-25: Version 3.29.88
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-24: Version 3.29.87
+
+        Preserve message when rethrowing exception (issue 3583).
+
+        Fix escaped index JSON parsing (Chromium issue 416449).
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-23: Version 3.29.84
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-23: Version 3.29.83
+
+        Performance and stability improvements on all platforms.
+
+
+2014-09-23: Version 3.29.82
+
+        Fix escaped index JSON parsing (Chromium issue 416449).
+
+        Performance and stability improvements on all platforms.
+
+
 2014-09-17: Version 3.29.70
 
         Enable ES6 generators (issue 2355).
