When editing this page please be as detailed as possible. Examples are encouraged!

Changed:

  • The customFds option to the child_process.spawn method is deprecated. Only the values -1, 0, 1, 2 will work with customFds now and only if those are TTY file descriptors. You can however use the stdinStream, stdoutStream, and stderrStream options to achieve similar functionality.
  • You can no longer send a file descriptor through a unix pipe. Instead you can send a handle via child_process.fork.
  • The 'unix_dgram' type to the dgram.createSocket() is no longer supported.
  • fs.symlink takes an optional mode argument, which can either be 'dir' or 'file'. The default is 'file'. This argument is only needed for Windows (it's ignored on other platforms).
  • http.Agent.appendMessage was removed.
  • http.getAgent() was removed. Use http.globalAgent instead.
  • Not httpAgent but http.ClientRequest emits 'upgrade' event.
  • https.request() and https.get() with default Agent ignore key, cert and ca options. Use custom Agent.
  • net.Server.listenFD() was no longer supported.
  • The require.paths have been removed (use NODE_PATH environment variable instead).
  • C++ node::EventEmitter has been removed. Instead use node::MakeCallback()
  • EventEmitter.removeAllListeners() allows to remove all listeners at once.
  • process.ENV was removed. Use process.env instead.
  • process.ARGV was removed. Use process.argv instead.
  • process.binding('stdio') was removed. This was a private API. You shouldn't have been using it in the first place.
  • process.stdin, process.stdout and process.stderr are getters now.
  • [V8] RegExp was no longer a Function.

  • assert(val) as a shorthand for assert.ok(val)
  • Buffer supports 'hex' encoding.
