buffer:
-
You can now supply an encoding argument when filling a BufferBuffer#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 withspawn() 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

process.nextTick() (Ruben Bridgewater) #5092
-
path module (Brian White) #5123
-
querystring module (Brian White) #5012
-
