Version 3.4.9.
Added support for debugger inspection of locals in optimized frames (issue 1140).
Fixed SConstruct to pass correct defines to samples/preparser when building with library=shared.
Made date parser handle ES5 Date Time Strings correctly (issue 1498).
Fixed a bug in Object.defineProperty on the arguments object.
Performance improvetments on all platforms.
