值得关注的改进包括：

buffer:

You can now supply an encoding argument when filling a Buffer Buffer#fill(string[, start[, end]][, encoding]), supplying an existing Buffer will also work with Buffer#fill(buffer[, start[, end]]). See the API documentation for details on how this works. (Trevor Norris) #4935
Buffer#indexOf() no longer requires a byteOffset argument if you also wish to specify an encoding: Buffer#indexOf(val[, byteOffset][, encoding]). (Trevor Norris) #4803

child_process: spawn() and spawnSync() now support a 'shell' option to allow for optional execution of the given command inside a shell. If set to true, cmd.exe will be used on Windows and /bin/sh elsewhere. A path to a custom shell can also be passed to override these defaults. On Windows, this option allows .bat. and .cmd files to be executed with spawn() and spawnSync(). (Colin Ihrig) #4598
http_parser: Update to http-parser 2.6.2 to fix an unintentionally strict limitation of allowable header characters (James M Snell) #5237
dgram: socket.send() now supports accepts an array of Buffers or Strings as the first argument. See the API docs for details on how this works. (Matteo Collina) #4374
http: Fix a bug where handling headers will mistakenly trigger an 'upgrade' event where the server is just advertising its protocols. This bug can prevent HTTP clients from communicating with HTTP/2 enabled servers. (Fedor Indutny) #4337
net: Added a listening Boolean property to net and http servers to indicate whether the server is listening for connections. (José Moreira) #4743
node: The C++ node::MakeCallback() API is now reentrant and calling it from inside another MakeCallback() call no longer causes the nextTick queue or Promises microtask queue to be processed out of order. (Trevor Norris) #4507
tls: Add a new tlsSocket.getProtocol() method to get the negotiated TLS protocol version of the current connection. (Brian White) #4995
vm: Introduce new 'produceCachedData' and 'cachedData' options to new vm.Script() to interact with V8's code cache. When a new vm.Script object is created with the 'produceCachedData' set to true a Buffer with V8's code cache data will be produced and stored in cachedData property of the returned object. This data in turn may be supplied back to another vm.Script() object with a 'cachedData' option if the supplied source is the same. Successfully executing a script from cached data can speed up instantiation time. See the API docs for details. (Fedor Indutny) #4777
performance: Improvements in:

process.nextTick() (Ruben Bridgewater) #5092
path module (Brian White) #5123
querystring module (Brian White) #5012
streams module when processing small chunks (Matteo Collina) #4354
