+        stack overflow exceptions.
+
+        Fixed bugs that caused catch variables and variables introduced by

 2008-12-11: Version 0.4.6
 
         Fixed exception reporting bug where certain exceptions were
         incorrectly reported as uncaught.
 
         Improved the memory allocation strategy used during compilation to
         make running out of memory when compiling huge scripts less
         likely.
 
         Optimized String.replace by avoiding the construction of certain
         sub strings.
 
         Fixed bug in code generation for large switch statements on ARM.
 
         Fixed bug that caused V8 to change the global object template
         passed in by the user.
 
         Changed the API for creating object groups used during garbage
         collection.  Entire object groups are now passed to V8 instead of
         individual members of the groups.

 2008-12-03: Version 0.4.5
 
         Added experimental API support for allocating V8 symbols as
         external strings.
 
         Fixed bugs in debugging support on ARM.
 
         Changed eval implementation to correctly detect whether or not a
         call to eval is aliased.
 
         Fixed bug caused by a combination of the compilation cache and
         dictionary probing in native code.  The bug caused us to sometimes
         call functions that had not yet been compiled.
 
         Added platform support for FreeBSD.
 
         Added support for building V8 on Windows with either the shared or
         static version of MSVCRT

         Added the v8::jscre namespace around the jscre functions to avoid
         link errors (duplicate symbols) when building Google Chrome.
 
         Added support for calling a JavaScript function with the current
         debugger execution context as its argument to the debugger
         interface.
 
         Changed the type of names of counters from wchar_t to char.

         Implemented shell support for passing arguments to a script from

         Fixed bug in date code that made certain date functions return -0
         instead of 0 for dates before the epoch.
 
         Restricted applications of eval so it can only be used in the
         context of the associated global object.
 
         Treat byte-order marks as whitespace characters.

 2008-11-04: Version 0.4.3
 
         Added support for API accessors that prohibit overwriting by
         accessors defined in JavaScript code by using __defineGetter__ and
         __defineSetter__.
 
         Improved handling of conditionals in test status files.
 
         Introduced access control in propertyIsEnumerable.
 
         Improved performance of some string operations by caching
         information about the type of the string between operations.
 
         Fixed bug in fast-case code for switch statements that only have
         integer labels.

         Improved performance of Array.prototype.concat by moving the

         Fixed heap growth policy to avoid growing old space to its maximum
         capacity before doing a garbage collection and fixed issue that
         would lead to artificial out of memory situations (issue 129).

         Changed the toString behavior on the built-in object constructors

         Improved handling of object literals by canonicalizing object
         literal maps.  This will allow JSON objects with the same set of
         properties to share the same map making inline caching work better
         for JSON objects.

         Generalized the EvalCache into a CompilationCache and enabled it

         whenever a mark-sweep collection is started.

         Improved performance of garbage collection by moving the
         function that updates pointers during compacting collection
         into the updating visitor.  This gives the compiler a better
         chance to inline and avoid a function call per (potential)
