ChangeLog

+2012-02-28: Version 3.9.12
+
+        Fix the negative lookup stub to handle deleted entries in a dictionary.
+        (issue 1964)
+
+        Add a new API where the host can supply a callback function. The
+        callback function can resolve the location of a return address on stack
+        to the location where a return-address rewriting profiler stashed the
+        original return address.
+
+        When compiling for-in pass correct context value to the increment
+        instruction. (Chromium issue http://crbug.com/115646)
+
+        Update breakpoints set with partial file name after compile.
+        (issue 1853)
+
+
 2012-02-27: Version 3.9.11
