Node.js 今天发布两个更新版本，分别是：
4.4.0
SEMVER-MINOR 变化包括：
deps:
An update to v8 that introduces a new flag --perf_basic_prof_only_functions (Ali Ijaz Sheikh) #3609
http:
A new feature in http(s) agent that catches errors on keep alived connections (José F. Romaniello) #4482
src:
Better support for Big-Endian systems (Bryon Leung) #3410
tls:
A new feature that allows you to pass common SSL options to tls.createSecurePair (Коренберг Марк) #2441
tools:
a new flag --prof-process which will execute the tick processor on the provided isolate files (Matt Loring) #4021
Notable semver patch changes include:
build:
Support python path that includes spaces. This should be of particular interest to our Windows users who may have python living in c:/Program Files (Felix Becker) #4841
https:
A potential fix for #3692 HTTP/HTTPS client requests throwing EPROTO (Fedor Indutny) #4982
installer:
More readable profiling information from isolate tick logs (Matt Loring) #3032
npm:
upgrade to npm 2.14.20 (Kat Marchán) #5510
process:
Add support for symbols in event emitters. Symbols didn't exist when it was written ¯_(ツ)_/¯ (cjihrig) #4798
querystring:
querystring.parse() is now 13-22% faster! (Brian White) #4675
streams:
performance improvements for moving small buffers that shows a 5% throughput gain. IoT projects have been seen to be as much as 10% faster with this change! (Matteo Collina) #4354
tools:
eslint has been updated to version 2.1.0 (Rich Trott) #5214
5.8.0 值得关注的改进内容：
child_process: send() now accepts an options parameter (cjihrig) #5283.
Currently the only option is keepOpen, which keeps the underlying socket open after the message is sent.
constants: ENGINE_METHOD_RSA is now correctly exposed (Sam Roberts) #5463.
Fixed two regressions which originated in v5.7.0:
http: Errors inside of http client callbacks now propagate correctly (Trevor Norris) #5591.
path: Fixed normalization of absolute paths (Evan Lucas) #5589.
repl: start() no longer requires an options parameter (cjihrig) #5388.
util: Improved format() performance 50-300% (Evan Lucas) #5360.
