io.js 2.0.1 发布，此版本值得关注的更新如下：

• async_wrap: (Trevor Norris) #1614

  • it is now possible to filter by providers

  • bit flags have been removed and replaced with method calls on the binding object

  • note that this is an unstable API so feature additions and breaking changes won't change io.js semver

• libuv: resolves numerous io.js issues:

  • #862 prevent spawning child processes with invalid stdio file descriptors

  • #1397 fix EPERM error with fs.access(W_OK) on Windows

  • #1621 build errors associated with the bundled libuv

  • #1512 should properly fix Windows termination errors

• addons: the NODE_DEPRECATED macro was causing problems when compiling addons with older compilers, this should now be resolved (Ben Noordhuis) #1626

• V8: upgrade V8 from 4.2.77.18 to 4.2.77.20 with minor fixes, including a bug preventing builds on FreeBSD
