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
