IO.js 服务器端 JS 引擎
IO.js 是为 V8 引擎编写的基于事件 IO 的实现。io.js可以说是彻底从NodeJS里分离出来的一条分支。既然是分支，io.js便也基本兼容NodeJS的各种API，连执行指令也依旧兼容Node的 node XXX （新指令是 iojs XXX ）。不过io.js采纳了最新版本的V8引擎，并也将会时刻跟进V8的更新，也因此我们可以轻松地在io.js上抢先使用那些JavaScript ECMA-262规范上的新特性。
io.js 1.6.4 发布，此版本值得关注的更新如下：
npm: upgrade npm to 2.7.5. See npm CHANGELOG.md for details. Includes two important security fixes. Summary:
300834etar@2.0.0: Normalize symbolic links that point to targets outside the extraction root. This prevents packages containing symbolic links from overwriting targets outside the expected paths for a package. Thanks to Tim Cuthbertson and the team at Lift Security for working with the npm team to identify this issue. (@othiym23)
0dc6875semver@4.3.2: Package versions can be no more than 256 characters long. This prevents a situation in which parsing the version number can use exponentially more time and memory to parse, leading to a potential denial of service. Thanks to Adam Baldwin at Lift Security for bringing this to our attention. (@isaacs)
eab6184#7766 One last tweak to ensure that GitHub shortcuts work with private repositories. (@iarna)
a840a13#7746 Only fix up git URL paths when there are paths to fix up. (@othiym23)
openssl: preliminary work has been done for an upcoming upgrade to OpenSSL 1.0.2a #1325 (Shigeki Ohtsu). See #589 for additional details.
timers: a minor memory leak when timers are unreferenced was fixed, alongside some related timers issues #1330 (Fedor Indutny). This appears to have fixed the remaining leak reported in #1075.
android: it is now possible to compile io.js for Android and related devices #1307 (Giovanny Andres Gongora Granada).
