Node.js v6.3.0 Release Brief

by:

in Node.js on Jul 06 2016

This v6 release is the result of an enormous amount of work done recently, combined with the recent security releases which caused a feature hold-up.

As with all releases within major version lines, minor and patch upgrades should be drop-in replacements for previous versions.

Overview

Of a total of 155 commits:

32 were documentation-only commits.
18 only modify tests and 9 only affect internal tooling.
8 of the commits are related to dependencies as follows:
- npm was upgraded to 3.10.2, and then 3.10.3 By (Kat Marchán) #7515 & (Rebecca Turner) #7410 respectively.
- ICU was updated to include the data files for punycode handling. - (James M Snell) #7355
- v8_inspector was imported in #6792, #7385, #7302, & #7118.
One commit was back-ported onto V8:
- 7dfb5beeec as c544213717 - (Myles Borins) #7348
  - This fixes the typeof null === "undefined" JIT bug in V8.

src:
- Added a node::FreeEnvironment public C++ API. (Cheng Zhao) #3098
- Refactored require('constants'), constants are now available directly from their respective modules. (James M Snell) #6534
stream: Improved readable.read() performance by up to 70%. (Brian White) #7077
timers: setImmediate() is now up to 150% faster in some situations. (Andras) #6436
