2015-09-08, Version 4.0.0 (Stable) Releasev4.0.0

This list of changes is relative to the last io.js v3.x branch
release, v3.3.0. Please see the list of notable changes in the v3.x,
v2.x and v1.x releases for a more complete list of changes from
0.12.x. Note, that some changes in the v3.x series as well as major
breaking changes in this release constitute changes required for full
convergence of the Node.js and io.js projects.

* 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, i.e. .send(message[, sendHandle][, callback])
  (Ben Noordhuis) #2620.
* node: Rename "io.js" code to "Node.js" (cjihrig) #2367.
* 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. (Rod Vagg) #2700.
* npm: Upgrade to version 2.14.2 from 2.13.3, includes a security
  update, see https://github.com/npm/npm/releases/tag/v2.14.2 for more
  details, (Kat Marchán) #2696.
* timers: Improved timer performance from porting the 0.12
  implementation, plus minor fixes (Jeremiah Senkpiel) #2540,
  (Julien Gilli) nodejs/node-v0.x-archive#8751 nodejs/node-v0.x-archive#8905
* 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,
  (Sakthipriyan Vairamani) #2447.
* v8: Upgrade to version 4.5.103.30 from 4.4.63.30 (Ali Ijaz Sheikh) #2632.
  - Implement new TypedArray prototype methods: copyWithin(), every(),
    fill(), filter(), find(), findIndex(), forEach(), indexOf(),
    join(), lastIndexOf(), map(), reduce(), reduceRight(), reverse(),
    slice(), some(), sort(). See
    https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray
    for further information.
  - Implement new TypedArray.from() and TypedArray.of() functions. See
    https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray
    for further information.
  - Implement arrow functions. See
    https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions

Note, that some changes in the v3.x series as well as major breaking changes in this release constitute changes required for full convergence of the Node.js and io.js projects.
+
+* **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, i.e. `.send(message[, sendHandle][, callback])` (Ben Noordhuis) [#2620](https://github.com/nodejs/node/pull/2620).

+
+### Known issues
+
+See https://github.com/nodejs/node/labels/confirmed-bug for complete and current list of known issues.
+
+* Some uses of computed object shorthand properties are not handled correctly by the current version of V8. e.g. `[{ [prop]: val }]` evaluates to `[{}]`. [#2507](https://github.com/nodejs/node/issues/2507)
+* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/node/issues/1264).
+* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/node/issues/690)
+* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/node/issues/894)
+* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/node/issues/1435).
