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

Changed:

  • Buffer
    • The length optional third parameter was added to Buffer.write()
  • child_process
    • 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.
  • dgram
    • The 'unix_dgram' type to the dgram.createSocket() is no longer supported.
  • events
    • C++ node::EventEmitter has been removed. Instead use node::MakeCallback()
    • EventEmitter.removeAllListeners() allows to remove all listeners at once.
  • fs
    • 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
    • http.request() and http.get() use Connection: Keep-Alive by default.
    • http.Agent.appendMessage was removed.
    • http.getAgent() was removed. Use http.globalAgent instead.
    • Not httpAgent but http.ClientRequest emits 'upgrade' event.
  • https
    • https.request() and https.get() with default Agent ignore key, cert and ca options. Use custom Agent.
  • Module system
    • The require.paths have been removed (use NODE_PATH environment variable instead).
  • net
    • net.Server.listenFD() was no longer supported.
  • process
    • 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.
    • process.memoryUsage().vsize was removed. You don't need it.
  • tls
    • tls.CleartextStream does not emit 'end' event. Use 'close' event instead.
  • V8 (v3.1 to v3.7)
    • RegExp was no longer a Function. Use RegExp.exec() instead.

Added:

  • assert
    • assert(val) as a shorthand for assert.ok(val)
  • Buffer
    • 'hex' encoding.
    • Buffer.readInt8()/readInt16BE()/readInt16LE()/readInt32LE()/readInt32BE()
    • Buffer.readUInt8()/readUInt16BE()/readUInt16LE()/rreadUInt32LE()/readUInt32BE()
    • Buffer.readFloatBE()/readFloadLE()/readDoubleBE()/readDoubleLE()
    • Buffer.writeInt8()/writeInt16BE()/writeInt16LE()/write32BE()/write32LE()
    • Buffer.writeUInt8()/writeUInt16BE()/writeUInt16LE()/writeU32BE()/writeU32LE()
    • Buffer.writeFloatBE()/writeFloatLE()/writeDoubleBE()/writeDoubleLE()
    • Buffer.fill()
    • Typed Arrays
  • child_process
    • child_process.fork()
  • crypto
    • crypto.createDiffieHellman(), crypto.pbkdf2(), crypto.randomBytes()
  • fs
    • fs.utimes()/utimesSync(), fs.futimes()/futimesSync()
    • fs.watch
    • start option to fs.createReadStream() and fs.createWriteStream().
  • http
    • http.ClientRequest.setTimeout()/setNoDelay()/setSocketKeepAlive()
  • Module system
    • .json module.
    • module.require()
  • net
    • net.connect()
    • net.Socket.remotePort, bytesRead, bytesWrite
  • os
    • os.arch(), os.platform(), os.uptime(), os.getNetworkInterfaces()
  • path
    • path.relative()
  • process
    • process.arch, process.uptime()
  • tls
  • util
    • util.format()
  • zlib module http://nodejs.org/docs/latest/api/zlib.html
