从node分离出来农民起义的iojs终于取得了革命胜利。现在node的版本一下从0.12.x飞升到了4.0.0。

Node.js ChangeLog
2015-09-08, Version 4.0.0 (Stable), @rvagg

Notable changes

This list of changes is relative to the last io.js v3.x branch release, v3.3.0. Please see the list of notable changes in the v3.x, v2.x and v1.x releases for a more complete list of changes from 0.12.x. Note, that some changes in the v3.x series as well as major breaking changes in this release constitute changes required for full convergence of the Node.js and io.js projects.

child_process: ChildProcess.prototype.send() and process.send() operate asynchronously across all platforms so an optional callback parameter has been introduced that will be invoked once the message has been sent, i.e. .send(message[, sendHandle][, callback]) (Ben Noordhuis) #2620.
node: Rename "io.js" code to "Node.js" (cjihrig) #2367.
node-gyp: This release bundles an updated version of node-gyp that works with all versions of Node.js and io.js including nightly and release candidate builds. From io.js v3 and Node.js v4 onward, it will only download a headers tarball when building addons rather than the entire source. (Rod Vagg) #2700
npm: Upgrade to version 2.14.2 from 2.13.3, includes a security update, see https://github.com/npm/npm/releases/tag/v2.14.2 for more details, (Kat Marchán) #2696.
timers: Improved timer performance from porting the 0.12 implementation, plus minor fixes (Jeremiah Senkpiel) #2540, (Julien Gilli) nodejs/node-v0.x-archive#8751 nodejs/node-v0.x-archive#8905
util: The util.is*() functions have been deprecated, beginning with deprecation warnings in the documentation for this release, users are encouraged to seek more robust alternatives in the npm registry, (Sakthipriyan Vairamani) #2447.
v8: Upgrade to version 4.5.103.30 from 4.4.63.30 (Ali Ijaz Sheikh) #2632.
Implement new TypedArray prototype methods: copyWithin(), every(), fill(), filter(), find(), findIndex(), forEach(), indexOf(), join(), lastIndexOf(), map(), reduce(), reduceRight(), reverse(), slice(), some(), sort(). See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray for further information.
Implement new TypedArray.from() and TypedArray.of() functions. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray for further information.
Implement arrow functions, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions for further information.

以上是搬过来的changeLog，同时在changeLog页面往下翻一番，全都是iojs之前的版本号，很明显node原本的项目是直接被iojs项目覆盖掉了，注意这一行

node: Rename "io.js" code to "Node.js" (cjihrig) #2367.

iojs重命名为nodejs，革命军变成了正规军，推翻了原本的帝国统治。

现在点开iojs.org官网里的changelog也是直接跳转到https://github.com/nodejs/node/blob/master/CHANGELOG.md,也就是node的changelog。

这对native mod开发者来说是个福音，不用再去考虑兼容iojs和node携带的两个版本差距悬殊的v8版本了。
