Version 3.5.4
Added preliminary implementation of ES Harmony weak maps. Weak maps can be enabled by the flag --harmony_weakmaps.
Introduced a toplevel Makefile to support GYP-based building. GYP can be found at http://gyp.googlecode.com.
Fixed a bug in the length property of functions created by Function.prototype.bind.
Reduced malloc heap allocation on process startup.
Several important code generation bug fixes.
Performance improvements on all platforms.
