io.js 1.6.1 发布，此版本值得关注的更新如下：
path: New type-checking on path.resolve() #1153 uncovered some edge-cases being relied upon in the wild, most notably path.dirname(undefined). Type-checking has been loosened for path.dirname(), path.basename(), and path.extname() (Colin Ihrig) #1216.
querystring：对 querystring.parse() 和 querystring.stringify() 进行了内部优化 #847 prevented Number literals from being properly converted via querystring.escape() #1208, exposing a blind-spot in the test suite. The bug and the tests have now been fixed (Jeremiah Senkpiel) #1213.
IO.js 是为 V8 引擎编写的基于事件 IO 的实现。
