Nodejs was updated to v4.0.0, bringing features, bug and security fixes.

* 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.
* node: Rename "io.js" code to "Node.js".
* 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.
* npm: Upgrade to version 2.14.2 from 2.13.3, includes a security
update.
* timers: Improved timer performance from porting the 0.12
implementation, plus minor fixes.
* 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.
* v8: Upgrade to version 4.5.103.30 from 4.4.63.30
