Some of the key improvements and features in this version include:


  • Buffers are now created in JavaScript, rather than C++. This increases the speed of buffer creation
  • Buffer#slice() now uses Uint8Array#subarray() internally, increasing slice() performance 


  • fs.utimes() now properly converts numeric strings, NaN, and Infinity.
  • fs.WriteStream now implements _writev, allowing for super-fast bulk writes. 

http: Fixed an issue with certain write() sizes causing errors when using http.request()

npm: Upgrade to version 2.14.3, see for more details

src: V8 cpu profiling no longer erroneously shows idle time

timers: #ref() and #unref() now return the timer they belong to
