- Add support for Intel's VTune JIT profiling when compiled with `--enable-vtune-profiling`. For more information about VTune, see <https://software.intel.com/en-us/node/544211>. (Chunyang Dai) [#3785](https://github.com/nodejs/node/pull/3785).

* **crypto**:
- Simplify use of ECDH (Elliptic Curve Diffie-Hellman) objects (created via `crypto.createECDH(curve_name)`) with private keys that are not dynamically generated via `generateKeys()`. The public key is now computed when explicitly setting a private key. Added validity checks to reduce the possibility of computing weak or invalid shared secrets. Also, deprecated the `setPublicKey()` method for ECDH objects as its usage is unnecessary and can lead to inconsistent state. (Michael Ruddy) [#3511](https://github.com/nodejs/node/pull/3511).
- Update root certificates from the current list stored maintained by Mozilla NSS. (Ben Noordhuis) [#3951](https://github.com/nodejs/node/pull/3951).

Security Update
### Notable changes
* build: Add support for Microsoft Visual Studio 2015
* npm: Upgrade to v1.4.29 from v1.4.28. A special one-off release as part of the strategy to get a version of npm into Node.js v0.10.x that works with the current registry (https://github.com/nodejs/LTS/issues/37). This version of npm prints out a banner each time it is run. The banner warns that the next standard release of Node.js v0.10.x will ship with a version of npm v2.

## 2015-11-17, Version 5.1.0 (Stable), @Fishrock123
### Notable changes
* **buffer**: The `noAssert` option for many buffer functions will now silently drop invalid write values rather than crashing (P.S.V.R) [#3767](https://github.com/nodejs/node/pull/3767).
- This makes the behavior match what the docs suggest.
* **child_process**: `child.send()` now properly returns a boolean like the docs suggest (Rich Trott) [#3577](https://github.com/nodejs/node/pull/3577).
* **doc**: All of the API docs have been re-ordered so as to read in alphabetical order (Tristian Flanagan) [#3662](https://github.com/nodejs/node/pull/3662).
* **http_parser**: update http-parser to 2.6.0 from 2.5.0 (James M Snell) [#3569](https://github.com/nodejs/node/pull/3569).
- Now supports the following HTTP methods: `LINK`, `UNLINK`, `BIND`, `REBIND`, `UNBIND`.
- Also added ACL and IPv6 Zone ID support.
* **npm**: upgrade npm to 3.3.12 from v3.3.6 (Rebecca Turner) [#3685](https://github.com/nodejs/node/pull/3685).
- See the release notes for [v3.3.7](https://github.com/npm/npm/releases/tag/v3.3.7), [v3.3.8](https://github.com/npm/npm/releases/tag/v3.3.8), [v3.3.9](https://github.com/npm/npm/releases/tag/v3.3.9), [v3.3.10](https://github.com/npm/npm/releases/tag/v3.3.10), [v3.3.11](https://github.com/npm/npm/releases/tag/v3.3.11), and [v3.3.12](https://github.com/npm/npm/releases/tag/v3.3.12) for more details.
* **repl**: The REPL no longer crashes if the [persistent history](https://nodejs.org/api/repl.html#repl_persistent_history) file cannot be opened (Evan Lucas) [#3630](https://github.com/nodejs/node/pull/3630).
* **tls**: The default `sessionIdContext` now uses SHA1 in FIPS mode rather than MD5 (Stefan Budeanu) [#3755](https://github.com/nodejs/node/pull/3755).
* **v8**: Added some more useful post-mortem data (Fedor Indutny) [#3779](https://github.com/nodejs/node/pull/3779).

* **buffer**: _(Breaking)_ Removed both `'raw'` and `'raws'` encoding types from `Buffer`, these have been deprecated for a long time (Sakthipriyan Vairamani) [#2859](https://github.com/nodejs/node/pull/2859).
* **console**: _(Breaking)_ Values reported by `console.time()` now have 3 decimals of accuracy added (Michaël Zasso) [#3166](https://github.com/nodejs/node/pull/3166).
* **fs**:
-`fs.readFile*()`, `fs.writeFile*()`, and `fs.appendFile*()` now also accept a file descriptor as their first argument (Johannes Wüller) [#3163](https://github.com/nodejs/node/pull/3163).
- _(Breaking)_ In `fs.readFile()`, if an encoding is specified and the internal `toString()` fails the error is no longer _thrown_ but is passed to the callback (Evan Lucas) [#3485](https://github.com/nodejs/node/pull/3485).
- _(Breaking)_ In `fs.read()` (using the `fs.read(fd, length, position, encoding, callback)` form), if the internal `toString()` fails the error is no longer _thrown_ but is passed to the callback (Evan Lucas) [#3503](https://github.com/nodejs/node/pull/3503).
* **http**:
- Fixed a bug where pipelined http requests would stall (Fedor Indutny) [#3342](https://github.com/nodejs/node/pull/3342).
- _(Breaking)_ When parsing HTTP, don't add duplicates of the following headers: `Retry-After`, `ETag`, `Last-Modified`, `Server`, `Age`, `Expires`. This is in addition to the following headers which already block duplicates: `Content-Type`, `Content-Length`, `User-Agent`, `Referer`, `Host`, `Authorization`, `Proxy-Authorization`, `If-Modified-Since`, `If-Unmodified-Since`, `From`, `Location`, `Max-Forwards` (James M Snell) [#3090](https://github.com/nodejs/node/pull/3090).
- _(Breaking)_ The `callback` argument to `OutgoingMessage#setTimeout()` must be a function or a `TypeError` is thrown (James M Snell) [#3090](https://github.com/nodejs/node/pull/3090).
- _(Breaking)_ HTTP methods and header names must now conform to the RFC 2616 "token" rule, a list of allowed characters that excludes control characters and a number of _separator_ characters. Specifically, methods and header names must now match ```/^[a-zA-Z0-9_!#$%&'*+.^`|~-]+$/``` or a `TypeError` will be thrown (James M Snell) [#2526](https://github.com/nodejs/node/pull/2526).
* **node**:
- _(Breaking)_ Deprecated the `_linklist` module (Rich Trott) [#3078](https://github.com/nodejs/node/pull/3078).
- _(Breaking)_ Removed `require.paths` and `require.registerExtension()`, both had been previously set to throw `Error` when accessed (Sakthipriyan Vairamani) [#2922](https://github.com/nodejs/node/pull/2922).
* **npm**: Upgraded to version 3.3.6 from 2.14.7, see https://github.com/npm/npm/releases/tag/v3.3.6 for more details. This is a major version bump for npm and it has seen a significant amount of change. Please see the original [npm v3.0.0 release notes](https://github.com/npm/npm/blob/master/CHANGELOG.md#v300-2015-06-25) for a list of major changes (Rebecca Turner) [#3310](https://github.com/nodejs/node/pull/3310).
* **src**: _(Breaking)_ Bumped `NODE_MODULE_VERSION` to `47` from `46`, this is necessary due to the V8 upgrade. Native add-ons will need to be recompiled (Rod Vagg) [#3400](https://github.com/nodejs/node/pull/3400).
* **timers**: Attempt to reuse the timer handle for `setTimeout().unref()`. This fixes a long-standing known issue where unrefed timers would perviously hold `beforeExit` open (Fedor Indutny) [#3407](https://github.com/nodejs/node/pull/3407).
* **tls**:
- Added ALPN Support (Shigeki Ohtsu) [#2564](https://github.com/nodejs/node/pull/2564).
- TLS options can now be passed in an object to `createSecurePair()` (Коренберг Марк) [#2441](https://github.com/nodejs/node/pull/2441).
- _(Breaking)_ The default minimum DH key size for `tls.connect()` is now 1024 bits and a warning is shown when DH key size is less than 2048 bits. This a security consideration to prevent "logjam" attacks. A new `minDHSize` TLS option can be used to override the default. (Shigeki Ohtsu) [#1831](https://github.com/nodejs/node/pull/1831).
* **util**:
- _(Breaking)_ `util.p()` was deprecated for years, and has now been removed (Wyatt Preul) [#3432](https://github.com/nodejs/node/pull/3432).
- _(Breaking)_ `util.inherits()` can now work with ES6 classes. This is considered a breaking change because of potential subtle side-effects caused by a change from directly reassigning the prototype of the constructor using `ctor.prototype = Object.create(superCtor.prototype, { constructor: { ... } })` to using `Object.setPrototypeOf(ctor.prototype, superCtor.prototype)` (Michaël Zasso) [#3455](https://github.com/nodejs/node/pull/3455).
* **v8**: _(Breaking)_ Upgraded to 4.6.85.25 from 4.5.103.35 (Ali Ijaz Sheikh) [#3351](https://github.com/nodejs/node/pull/3351).
- Implements the spread operator, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator for further information.
- Implements `new.target`, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/new.target for further information.
* **zlib**: Decompression now throws on truncated input (e.g. unexpected end of file) (Yuval Brik) [#2595](https://github.com/nodejs/node/pull/2595).
### Known issues
* 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).
* Unicode characters in filesystem paths are not handled consistently across platforms or Node.js APIs. See [#2088](https://github.com/nodejs/node/issues/2088), [#3401](https://github.com/nodejs/node/issues/3401) and [#3519](https://github.com/nodejs/node/issues/3519).

### Known issues
* When a server queues a large amount of data to send to a client over a pipelined HTTP connection, the underlying socket may be destroyed. See [#3332](https://github.com/nodejs/node/issues/3332) and [#3342](https://github.com/nodejs/node/pull/3342).
* 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).

* **buffer**: Fixed a bug introduced in v4.1.0 where allocating a new zero-length buffer can result in the _next_ allocation of a TypedArray in JavaScript not being zero-filled. In certain circumstances this could result in data leakage via reuse of memory space in TypedArrays, breaking the normally safe assumption that TypedArrays should be always zero-filled. (Trevor Norris) [#2931](https://github.com/nodejs/node/pull/2931).
* **http**: Guard against response-splitting of HTTP trailing headers added via [`response.addTrailers()`](https://nodejs.org/api/http.html#http_response_addtrailers_headers) by removing new-line (`[\r\n]`) characters from values. Note that standard header values are already stripped of new-line characters. The expected security impact is low because trailing headers are rarely used. (Ben Noordhuis) [#2945](https://github.com/nodejs/node/pull/2945).
* **npm**: Upgrade to npm 2.14.4 from 2.14.3, see [release notes](https://github.com/npm/npm/releases/tag/v2.14.4) for full details (Kat Marchán) [#2958](https://github.com/nodejs/node/pull/2958)

## 2015-09-17, Version 4.1.0 (Stable), @Fishrock123
### Notable changes
* **buffer**:
- Buffers are now created in JavaScript, rather than C++. This increases the speed of buffer creation (Trevor Norris) [#2866](https://github.com/nodejs/node/pull/2866).
-`fs.utimes()` now properly converts numeric strings, `NaN`, and `Infinity` (Yazhong Liu) [#2387](https://github.com/nodejs/node/pull/2387).
-`fs.WriteStream` now implements `_writev`, allowing for super-fast bulk writes (Ron Korving) [#2167](https://github.com/nodejs/node/pull/2167).
* **http**: Fixed an issue with certain `write()` sizes causing errors when using `http.request()` (Fedor Indutny) [#2824](https://github.com/nodejs/node/pull/2824).
* **npm**: Upgrade to version 2.14.3, see https://github.com/npm/npm/releases/tag/v2.14.3 for more details (Kat Marchán) [#2822](https://github.com/nodejs/node/pull/2822).
* **src**: V8 cpu profiling no longer erroneously shows idle time (Oleksandr Chekhovskyi) [#2324](https://github.com/nodejs/node/pull/2324).
* **timers**: `#ref()` and `#unref()` now return the timer they belong to (Sam Roberts) [#2905](https://github.com/nodejs/node/pull/2905).
* **v8**: Lateral upgrade to 4.5.103.33 from 4.5.103.30, contains minor fixes (Ali Ijaz Sheikh) [#2870](https://github.com/nodejs/node/pull/2870).
- This fixes a previously known bug where some computed object shorthand properties did not work correctly ([#2507](https://github.com/nodejs/node/issues/2507)).
### Known issues
See https://github.com/nodejs/node/labels/confirmed-bug for complete and current list of known issues.
* 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).

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](https://github.com/nodejs/node/pull/2620).
* **node**: Rename "io.js" code to "Node.js" (cjihrig) [#2367](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/2696).
* **timers**: Improved timer performance from porting the 0.12 implementation, plus minor fixes (Jeremiah Senkpiel) [#2540](https://github.com/nodejs/node/pull/2540), (Julien Gilli) [nodejs/node-v0.x-archive#8751](https://github.com/nodejs/node-v0.x-archive/pull/8751) [nodejs/node-v0.x-archive#8905](https://github.com/nodejs/node-v0.x-archive/pull/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](https://github.com/nodejs/node/pull/2447).
* **v8**: Upgrade to version 4.5.103.30 from 4.4.63.30 (Ali Ijaz Sheikh) [#2632](https://github.com/nodejs/node/pull/2632).

* **tools**: The v8 tick processor now comes bundled with node (Matt Loring) [#2090](https://github.com/nodejs/node/pull/2090).
- This can be used by producing performance profiling output by running node with `--perf`, then running your appropriate platform's script on the output as found in [tools/v8-prof](https://github.com/nodejs/node/tree/master/tools/v8-prof).
* **util**: `util.inspect(obj)` now prints the constructor name of the object if there is one (Christopher Monsanto) [#1935](https://github.com/nodejs/io.js/pull/1935).

* [[`fb0f5d733f`](https://github.com/nodejs/node/commit/fb0f5d733f)] - **(SEMVER-MINOR)** **tools**: run the tick processor without building v8 (Matt Loring) [#2090](https://github.com/nodejs/node/pull/2090)
- Due to changes in V8, it has been necessary to reimplement `Buffer` on top of V8's `Uint8Array`. Every effort has been made to minimize the performance impact, however `Buffer` instantiation is measurably slower. Access operations may be faster in some circumstances but the exact performance profile and difference over previous versions will depend on how `Buffer` is used within applications. (Trevor Norris) [#1825](https://github.com/nodejs/node/pull/1825).
-`Buffer` can now take `ArrayBuffer`s as a constructor argument (Trevor Norris) [#2002](https://github.com/nodejs/node/pull/2002).
- When a single buffer is passed to `Buffer.concat()`, a new, copied `Buffer` object will be returned; previous behavior was to return the original `Buffer` object (Sakthipriyan Vairamani) [#1937](https://github.com/nodejs/node/pull/1937).
* **build**: PPC support has been added to core to allow compiling on pLinux BE and LE (AIX support coming soon) (Michael Dawson) [#2124](https://github.com/nodejs/node/pull/2124).
* **dgram**: If an error occurs within `socket.send()` and a callback has been provided, the error is only passed as the first argument to the callback and not emitted on the `socket` object; previous behavior was to do both (Matteo Collina & Chris Dickinson) [#1796](https://github.com/nodejs/node/pull/1796)
- Status codes now all use the official [IANA names](http://www.iana.org/assignments/http-status-codes) as per [RFC7231](https://tools.ietf.org/html/rfc7231), e.g. `http.STATUS_CODES[414]` now returns `'URI Too Long'` rather than `'Request-URI Too Large'` (jomo) [#1470](https://github.com/nodejs/node/pull/1470).
- Calling .getName() on an HTTP agent no longer returns a trailing colon, HTTPS agents will no longer return an extra colon near the middle of the string (Brendan Ashworth) [#1617](https://github.com/nodejs/node/pull/1617).
-`NODE_MODULE_VERSION` has been bumped to `45` to reflect the break in ABI (Rod Vagg) [#2096](https://github.com/nodejs/node/pull/2096).
- Introduce a new `process.release` object that contains a `name` property set to `'io.js'` and `sourceUrl`, `headersUrl` and `libUrl` (Windows only) properties containing URLs for the relevant resources; this is intended to be used by node-gyp (Rod Vagg) [#2154](https://github.com/nodejs/node/pull/2154).
- The version of node-gyp bundled with io.js now downloads and uses a tarball of header files from iojs.org rather than the full source for compiling native add-ons; it is hoped this is a temporary floating patch and the change will be upstreamed to node-gyp soon (Rod Vagg) [#2066](https://github.com/nodejs/node/pull/2066).
* **repl**: Persistent history is now enabled by default. The history file is located at ~/.node_repl_history, which can be overridden by the new environment variable `NODE_REPL_HISTORY`. This deprecates the previous `NODE_REPL_HISTORY_FILE` variable. Additionally, the format of the file has been changed to plain text to better handle file corruption. (Jeremiah Senkpiel) [#2224](https://github.com/nodejs/node/pull/2224).
* **smalloc**: The `smalloc` module has been removed as it is no longer possible to provide the API due to changes in V8 (Ben Noordhuis) [#2022](https://github.com/nodejs/node/pull/2022).
* **tls**: Add `server.getTicketKeys()` and `server.setTicketKeys()` methods for [TLS session key](https://www.ietf.org/rfc/rfc5077.txt) rotation (Fedor Indutny) [#2227](https://github.com/nodejs/node/pull/2227).
- ES6: `Array` can now be subclassed in strict mode
- ES6: Implement [rest parameters](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Functions/rest_parameters) in staging, use the `--harmony-rest-parameters` command line flag
- ES6: Implement the [spread operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator) in staging, use the `--harmony-spreadcalls` command line flag
- Removed `SetIndexedPropertiesToExternalArrayData` and related APIs, forcing a shift to `Buffer` to be reimplemented based on `Uint8Array`
- Introduction of `Maybe` and `MaybeLocal` C++ API for objects which _may_ or _may not_ have a value.

* **http**: Reverts the move of the `client` property of `IncomingMessage` to its prototype. Although undocumented, this property was used and assumed to be an "own property" in the wild, most notably by [request](https://github.com/request/request) which is used by npm. (Michaël Zasso) [#1852](https://github.com/nodejs/node/pull/1852).
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/node/issues/1264).

*`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).
* **node**: Speed-up `require()` by replacing usage of `fs.statSync()` and `fs.readFileSync()` with internal variants that are faster for this use-case and do not create as many objects for the garbage collector to clean up. The primary two benefits are: significant increase in application start-up time on typical applications and better start-up time for the debugger by eliminating almost all of the thousands of exception events. (Ben Noordhuis) [#1801](https://github.com/nodejs/node/pull/1801).
* **node**: Resolution of pre-load modules (`-r` or `--require`) now follows the standard `require()` rules rather than just resolving paths, so you can now pre-load modules in node_modules. (Ali Ijaz Sheikh) [#1812](https://github.com/nodejs/node/pull/1812).
* **npm**: Upgraded npm to v2.11.0. New hooks for `preversion`, `version`, and `postversion` lifecycle events, some SPDX-related license changes and license file inclusions. See the [release notes](https://github.com/npm/npm/releases/tag/v2.11.0) for full details.

* **crypto**: Diffie-Hellman key exchange (DHE) parameters (`'dhparams'`) must now be 1024 bits or longer or an error will be thrown. A warning will also be printed to the console if you supply less than 2048 bits. See https://weakdh.org/ for further context on this security concern. (Shigeki Ohtsu) [#1739](https://github.com/nodejs/node/pull/1739).

* **node**: To allow for chaining of methods, the `setTimeout()`, `setKeepAlive()`, `setNoDelay()`, `ref()` and `unref()` methods used in `'net'`, `'dgram'`, `'http'`, `'https'` and `'tls'` now return the current instance instead of `undefined` (Roman Reiss & Evan Lucas) [#1699](https://github.com/nodejs/node/pull/1699) [#1768](https://github.com/nodejs/node/pull/1768) [#1779](https://github.com/nodejs/node/pull/1779).

* **tls**: default ciphers have been updated to use gcm and aes128 (Mike MacCana) [#1660](https://github.com/nodejs/node/pull/1660)
* **build**: v8 snapshots have been re-enabled by default as suggested by the v8 team, since prior security issues have been resolved. This should give some perf improvements to both startup and vm context creation. (Trevor Norris) [#1663](https://github.com/nodejs/node/pull/1663)

* While not a *breaking change* the 'smalloc' module has been deprecated in anticipation of it becoming unsupportable with a future upgrade to V8 4.4. See [#1451](https://github.com/nodejs/node/issues/1451) for further information.
_Note: a new version of the 'url' module was reverted prior to release as it was decided the potential for breakage across the npm ecosystem was too great and that more compatibility work needed to be done before releasing it. See [#1602](https://github.com/nodejs/node/pull/1602) for further information._
* **net**: `socket.connect()` now accepts a `'lookup'` option for a custom DNS resolution mechanism, defaults to `dns.lookup()` (Evan Lucas) [#1505](https://github.com/nodejs/node/pull/1505)
* **npm**: Upgrade npm to 2.9.0. See the [v2.8.4](https://github.com/npm/npm/releases/tag/v2.8.4) and [v2.9.0](https://github.com/npm/npm/releases/tag/v2.9.0) release notes for details. Notable items:
- Add support for default author field to make `npm init -y` work without user-input (@othiym23) [npm/npm/d8eee6cf9d](https://github.com/npm/npm/commit/d8eee6cf9d2ff7aca68dfaed2de76824a3e0d9af)
- Include local modules in `npm outdated` and `npm update` (@ArnaudRinquin) [npm/npm#7426](https://github.com/npm/npm/issues/7426)
- The prefix used before the version number on `npm version` is now configurable via `tag-version-prefix` (@kkragenbrink) [npm/npm#8014](https://github.com/npm/npm/issues/8014)
* **os**: `os.tmpdir()` is now cross-platform consistent and will no longer returns a path with a trailing slash on any platform (Christian Tellnes) [#747](https://github.com/nodejs/node/pull/747)
-`process.nextTick()` performance has been improved by between 2-42% across the benchmark suite, notable because this is heavily used across core (Brian White) [#1571](https://github.com/nodejs/node/pull/1571)
- New `process.geteuid()`, `process.seteuid(id)`, `process.getegid()` and `process.setegid(id)` methods allow you to get and set effective UID and GID of the process (Evan Lucas) [#1536](https://github.com/nodejs/node/pull/1536)
- REPL history can be persisted across sessions if the `NODE_REPL_HISTORY_FILE` environment variable is set to a user accessible file, `NODE_REPL_HISTORY_SIZE` can set the maximum history size and defaults to `1000` (Chris Dickinson) [#1513](https://github.com/nodejs/node/pull/1513)
- The REPL can be placed in to one of three modes using the `NODE_REPL_MODE` environment variable: `sloppy`, `strict` or `magic` (default); the new `magic` mode will automatically run "strict mode only" statements in strict mode (Chris Dickinson) [#1513](https://github.com/nodejs/node/pull/1513)
* **V8**: upgrade to 4.2.77.18, see the [ChangeLog](https://chromium.googlesource.com/v8/v8/+/refs/heads/4.2.77/ChangeLog) for full details. Notable items:
- Classes have moved out of staging; the `class` keyword is now usable in strict mode without flags
- Object literal enhancements have moved out of staging; shorthand method and property syntax is now usable (`{ method() { }, property }`)
- Rest parameters (`function(...args) {}`) are implemented in staging behind the `--harmony-rest-parameters` flag
- Computed property names (`{['foo'+'bar']:'bam'}`) are implemented in staging behind the `--harmony-computed-property-names` flag
- Unicode escapes (`'\u{xxxx}'`) are implemented in staging behind the `--harmony_unicode` flag and the `--harmony_unicode_regexps` flag for use in regular expressions
- Random process termination on Windows fixed (Fedor Indutny) [#1512](https://github.com/nodejs/node/issues/1512) / [#1563](https://github.com/nodejs/node/pull/1563)
- The delay-load hook introduced to fix issues with process naming (iojs.exe / node.exe) has been made opt-out for native add-ons.

* **C++ API**: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js. `SealHandleScope` allows a C++ add-on author to _seal_ a `HandleScope` to prevent further, unintended allocations within it. Currently only enabled for debug builds of io.js. This feature helped detect the leak in [#1075](https://github.com/nodejs/node/issues/1075) and is now activated on the root `HandleScope` in io.js. (Fedor Indutny) [#1395](https://github.com/nodejs/node/pull/1395).
* **ARM**: This release includes significant work to improve the state of ARM support for builds and tests. The io.js CI cluster's ARMv6, ARMv7 and ARMv8 build servers are now all (mostly) reporting passing builds and tests.
* ARMv8 64-bit (AARCH64) is now properly supported, including a backported fix in libuv that was mistakenly detecting the existence of `epoll_wait()`. (Ben Noordhuis) [#1365](https://github.com/nodejs/node/pull/1365).
* ARMv6: [#1376](https://github.com/nodejs/node/issues/1376) reported a problem with `Math.exp()` on ARMv6 (incl Raspberry Pi). The culprit is erroneous codegen for ARMv6 when using the "fast math" feature of V8. `--nofast_math` has been turned on for all ARMv6 variants by default to avoid this, fast math can be turned back on with `--fast_math`. (Ben Noordhuis) [#1398](https://github.com/nodejs/node/pull/1398).
* Tests: timeouts have been tuned specifically for slower platforms, detected as ARMv6 and ARMv7. (Roman Reiss) [#1366](https://github.com/nodejs/node/pull/1366).
* **npm**: Upgrade npm to 2.7.6. See the [release notes](https://github.com/npm/npm/releases/tag/v2.7.6) for details. Summary:
* [`b747593`](https://github.com/npm/npm/commit/b7475936f473f029e6a027ba1b16277523747d0b)[#7630](https://github.com/npm/npm/issues/7630) Don't automatically log all git failures as errors. `maybeGithub` needs to be able to fail without logging to support its fallback logic. ([@othiym23](https://github.com/othiym23))
* [`78005eb`](https://github.com/npm/npm/commit/78005ebb6f4103c20f077669c3929b7ea46a4c0d)[#7743](https://github.com/npm/npm/issues/7743) Always quote arguments passed to `npm run-script`. This allows build systems and the like to safely escape glob patterns passed as arguments to `run-scripts` with `npm run-script <script> -- <arguments>`. This is a tricky change to test, and may be reverted or moved to `npm@3` if it turns out it breaks things for users. ([@mantoni](https://github.com/mantoni))
* [`da015ee`](https://github.com/npm/npm/commit/da015eee45f6daf384598151d06a9b57ffce136e)[#7074](https://github.com/npm/npm/issues/7074) `read-package-json@1.3.3`: `read-package-json` no longer caches `package.json` files, which trades a very small performance loss for the elimination of a large class of really annoying race conditions. See [#7074](https://github.com/npm/npm/issues/7074) for the grisly details. ([@othiym23](https://github.com/othiym23))

* **openssl**: preliminary work has been done for an upcoming upgrade to OpenSSL 1.0.2a [#1325](https://github.com/nodejs/node/pull/1325) (Shigeki Ohtsu). See [#589](https://github.com/nodejs/node/issues/589) for additional details.
* **timers**: a minor memory leak when timers are unreferenced was fixed, alongside some related timers issues [#1330](https://github.com/nodejs/node/pull/1330) (Fedor Indutny). This appears to have fixed the remaining leak reported in [#1075](https://github.com/nodejs/node/issues/1075).
* **android**: it is now possible to compile io.js for Android and related devices [#1307](https://github.com/nodejs/node/pull/1307) (Giovanny Andres Gongora Granada).
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/node/issues/1264).

* **fs**: corruption can be caused by `fs.writeFileSync()` and append-mode `fs.writeFile()` and `fs.writeFileSync()` under certain circumstances, reported in [#1058](https://github.com/nodejs/node/issues/1058), fixed in [#1063](https://github.com/nodejs/node/pull/1063) (Olov Lassus).
* **iojs**: an "internal modules" API has been introduced to allow core code to share JavaScript modules internally only without having to expose them as a public API, this feature is for core-only [#848](https://github.com/nodejs/node/pull/848) (Vladimir Kurchatkin).
-`Timer#close()` is now properly idempotent [#1288](https://github.com/nodejs/node/issues/1288) (Petka Antonov).
-`setTimeout()` will only run the callback once now after an `unref()` during the callback [#1231](https://github.com/nodejs/node/pull/1231) (Roman Reiss).
- NOTE: there are still other unresolved concerns with the timers code, such as [#1152](https://github.com/nodejs/node/pull/1152).
* **Windows**: a "delay-load hook" has been added for compiled add-ons on Windows that should alleviate some of the problems that Windows users may be experiencing with add-ons in io.js [#1251](https://github.com/nodejs/node/pull/1251) (Bert Belder).
* **V8**: minor bug-fix upgrade for V8 to 4.1.0.27.
* **npm**: upgrade npm to 2.7.4. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v274-2015-03-20) for details. Summary:
* [`1549106`](https://github.com/npm/npm/commit/1549106f518000633915686f5f1ccc6afcf77f8f) [#7641](https://github.com/npm/npm/issues/7641) Due to 448efd0, running `npm shrinkwrap --dev` caused production dependencies to no longer be included in `npm-shrinkwrap.json`. Whoopsie! ([@othiym23](https://github.com/othiym23))
* [`fb0ac26`](https://github.com/npm/npm/commit/fb0ac26eecdd76f6eaa4a96a865b7c6f52ce5aa5) [#7579](https://github.com/npm/npm/issues/7579) Only block removing files and links when we're sure npm isn't responsible for them. This change is hard to summarize, because if things are working correctly you should never see it, but if you want more context, just [go read the commit message](https://github.com/npm/npm/commit/fb0ac26eecdd76f6eaa4a96a865b7c6f52ce5aa5), which lays it all out.

* [`051c473`](https://github.com/npm/npm/commit/051c4738486a826300f205b71590781ce7744f01) [#7552](https://github.com/npm/npm/issues/7552) `bundledDependencies` are now properly included in the installation context. This is another fantastically hard-to-summarize bug, and once again, I encourage you to [read the commit message](https://github.com/npm/npm/commit/051c4738486a826300f205b71590781ce7744f01) if you're curious about the details.

* **Windows**: The ongoing work in improving the state of Windows support has resulted in full test suite passes once again. As noted in the release notes for v1.4.2, CI system and configuration problems prevented it from properly reporting problems with the Windows tests, the problems with the CI and the codebase appear to have been fully resolved.
* **FreeBSD**: A [kernel bug](https://lists.freebsd.org/pipermail/freebsd-current/2015-March/055043.html) impacting io.js/Node.js was [discovered](https://github.com/joyent/node/issues/9326) and a patch has been introduced to prevent it causing problems for io.js (Fedor Indutny) [#1218](https://github.com/nodejs/node/pull/1218).
* **module**: you can now `require('.')` instead of having to `require('./')`, this is considered a bugfix (Michaël Zasso) [#1185](https://github.com/nodejs/node/pull/1185).
* **v8**: updated to 4.1.0.25 including patches for `--max_old_space_size` values above `4096` and Solaris support, both of which are already included in io.js.
* Possible small memory leak(s) may still exist but have yet to be properly identified, details at [#1075](https://github.com/nodejs/node/issues/1075).
* Surrogate pair in REPL can freeze terminal [#690](https://github.com/nodejs/node/issues/690)

* **path**: New type-checking on `path.resolve()` [#1153](https://github.com/nodejs/node/pull/1153) uncovered some edge-cases being relied upon in the wild, most notably `path.dirname(undefined)`. Type-checking has been loosened for `path.dirname()`, `path.basename()`, and `path.extname()` (Colin Ihrig) [#1216](https://github.com/nodejs/node/pull/1216).
* **querystring**: Internal optimizations in `querystring.parse()` and `querystring.stringify()` [#847](https://github.com/nodejs/node/pull/847) prevented `Number` literals from being properly converted via `querystring.escape()` [#1208](https://github.com/nodejs/node/issues/1208), exposing a blind-spot in the test suite. The bug and the tests have now been fixed (Jeremiah Senkpiel) [#1213](https://github.com/nodejs/node/pull/1213).
* Possible remaining TLS-related memory leak(s), details at [#1075](https://github.com/nodejs/node/issues/1075).

* **node**: a new `-r` or `--require` command-line option can be used to pre-load modules at start-up (Ali Ijaz Sheikh) [#881](https://github.com/nodejs/node/pull/881).
* **querystring**: `parse()` and `stringify()` are now faster (Brian White) [#847](https://github.com/nodejs/node/pull/847).
* **http**: the `http.ClientRequest#flush()` method has been deprecated and replaced with `http.ClientRequest#flushHeaders()` to match the same change now in Node.js v0.12 as per [joyent/node#9048](https://github.com/joyent/node/pull/9048) (Yosuke Furukawa) [#1156](https://github.com/nodejs/node/pull/1156).
* **net**: allow `server.listen()` to accept a `String` option for `port`, e.g. `{ port: "1234" }`, to match the same option being accepted in `net.connect()` as of [joyent/node#9268](https://github.com/joyent/node/pull/9268) (Ben Noordhuis) [#1116](https://github.com/nodejs/node/pull/1116).
* **tls**: further work on the reported memory leak although there appears to be a minor leak remaining for the use-case in question, track progress at [#1075](https://github.com/nodejs/node/issues/1075).
* **v8**: backport a fix for an integer overflow when `--max_old_space_size` values above `4096` are used (Ben Noordhuis) [#1166](https://github.com/nodejs/node/pull/1166).
* **platforms**: the io.js CI system now reports passes on **FreeBSD** and **SmartOS** (_Solaris_).
* **npm**: upgrade npm to 2.7.1. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v271-2015-03-05) for details. Summary:
* [`6823807`](https://github.com/npm/npm/commit/6823807bba) [#7121](https://github.com/npm/npm/issues/7121) `npm install --save` for Git dependencies saves the URL passed in, instead of the temporary directory used to clone the remote repo. Fixes using Git dependencies when shrinkwwapping. In the process, rewrote the Git dependency caching code. Again. No more single-letter variable names, and a much clearer workflow.

_Note: version **1.4.0** was tagged and built but not released. A libuv bug was discovered in the process so the release was aborted. The tag was straight after [`a558cd0a61`](https://github.com/nodejs/node/commit/a558cd0a61) but has since been removed. We have jumped to 1.4.1 to avoid confusion._
* **process** / **promises**: An `'unhandledRejection'` event is now emitted on `process` whenever a `Promise` is rejected and no error handler is attached to the `Promise` within a turn of the event loop. A `'rejectionHandled'` event is now emitted whenever a `Promise` was rejected and an error handler was attached to it later than after an event loop turn. See the [process](https://iojs.org/api/process.html) documentation for more detail. [#758](https://github.com/nodejs/node/pull/758) (Petka Antonov)

- Simpler stream construction, see [readable-stream/issues#102](https://github.com/nodejs/readable-stream/issues/102) for details. This extends the streams base objects to make their constructors accept default implementation methods, reducing the boilerplate required to implement custom streams. An updated version of readable-stream will eventually be released to match this change in core. (@sonewman)

- The V8 JavaScript engine bundled with io.js was upgraded dramatically, from version 3.14.5.9 in Node.js v0.10.35 and 3.26.33 in Node.js v0.11.14 to 3.31.74.1 for io.js v1.0.0. This brings along many fixes and performance improvements, as well as additional support for new ES6 language features! For more information on this, check out [the io.js ES6 page](https://iojs.org/es6.html).
- Added `buf.writeUIntLE`, `buf.writeUIntBE`, `buf.writeIntLE`, `buf.writeIntBE`, `buf.readUIntLE`, `buf.readUIntBE`, `buf.readIntLE` and `buf.readIntBE` methods that read and write value up to 6 bytes.
- Updated the output of `buffer.toJSON()` to not be the same as an array. Instead it is an object specifically tagged as a buffer, which can be recovered by passing it to (a new overload of) the `Buffer` constructor.
- Added synchronous counterparts for the child process functions: `child_process.spawnSync`, `child_process.execSync`, and `child_process.execFileSync`.
- Added chaining support to `EventEmitter.setMaxListeners`.
- Updated `require('events')` to return the `EventEmitter` constructor, allowing the module to be used like `var EventEmitter = require('events')` instead of `var EventEmitter = require('events').EventEmitter`.
- Added MAC addresses, netmasks and scope IDs for IPv6 addresses to `os.networkInterfaces` method output.
- Updated `os.tmpdir` on Windows to use the `%SystemRoot%` or `%WINDIR%` environment variables instead of the hard-coded value of `c:\windows` when determining the temporary directory location.
data is returned as a result of a `.read` call that data will *also* be emitted on the `"data"` event.
As before, adding a listener for the `"readable"` or `"data"` event will start flowing the stream; as
will piping to another stream.
#### Writable streams
The ability to "bulk write" to underlying resources has been added to `Writable` streams. For stream
implementers, one can signal that a stream is bulk-writable by specifying a [_writev](https://iojs.org/api/stream.html#stream_writable_writev_chunks_callback) method.
Bulk writes will occur in two situations:
1. When a bulk-writable stream is clearing its backlog of buffered write requests,
2. or if an end user has made use of the new `.cork()` and `.uncork()` API methods.
`.cork` and `.uncork` allow the end user to control the buffering behavior of writable streams separate
from exerting backpressure. `.cork` indicates that the stream should accept new writes (up to `highWaterMark`),
while `.uncork` resets that behavior and attempts to bulk-write all buffered writes to the underlying resource.
The only core stream API that **currently** implements `_writev` is `net.Socket`.
In addition to the bulk-write changes, the performance of repeated small writes to non-bulk-writable streams
(such as `fs.WriteStream`) has been drastically improved. Users piping high volume log streams to disk should
see an improvement.
For a detailed overview of how streams3 interact, [see this diagram](https://cloud.githubusercontent.com/assets/37303/5728694/f9a3e300-9b20-11e4-9e14-a6938b3327f0.png).
The `vm` module has been rewritten to work better, based on the excellent [Contextify](https://github.com/brianmcd/contextify) native module. All of the functionality of Contextify is now in core, with improvements!
- Added `vm.isContext(object)` method to determine whether `object` has been contextified.
- Added `vm.runInDebugContext(code)` method to compile and execute `code` inside the V8 debug context.
- Updated `vm.createContext(sandbox)` to "contextify" the sandbox, making it suitable for use as a global for `vm` scripts, and then return it. It no longer creates a separate context object.
- Updated most `vm` and `vm.Script` methods to accept an `options` object, allowing you to configure a timeout for the script, the error display behavior, and sometimes the filename (for stack traces).
- Updated the supplied sandbox object to be used directly as the global, remove error-prone copying of properties back and forth between the supplied sandbox object and the global that appears inside the scripts run by the `vm` module.
In general it is recommended that you use [NAN](https://github.com/rvagg/nan) as a compatibility layer for your addons. This will also help with future changes in the V8 and Node/io.js C++ API. Most of the following changes are already handled by NAN-specific wrappers.
- Exposed method signature has changed from `Handle<Value> Method(const Arguments& args)` to `void Method(const v8::FunctionCallbackInfo<Value>& args)` with the newly introduced `FunctionCallbackInfo` also taking the return value via `args.GetReturnValue().Set(value)` instead of `scope.Close(value)`, `Arguments` has been removed.
- Similar changes have been made to property enumerators, property deleters, property query, index getter, index setter, index enumerator, index deleter, index query.
- V8 objects instantiated in C++ now require an `Isolate*` argument as the first argument. In most cases it is OK to simply pass `v8::Isolate::GetCurrent()`, e.g. `Date::New(Isolate::GetCurrent(), time)`, or `String::NewFromUtf8(Isolate::GetCurrent(), "foobar")`.
-`HandleScope scope` now requires an `Isolate*` argument, i.e. `HandleScope scope(isolate)`, in most cases `v8::Isolate::GetCurrent()` is OK.
- Similar changes have been made to `Locker` and `Unlocker`.
- V8 objects that need to "escape" a scope should be enclosed in a `EscapableHandleScope` rather than a `HandleScope` and should be returned with `scope.Escape(value)`.
- Exceptions are now thrown from isolates with `isolate->ThrowException(ExceptionObject)`.
-`Context::GetCurrent()` must now be done on an isolate, e.g. `Isolate::GetCurrent()->GetCurrentContext()`.
-`String::NewSymbol()` has been removed, use plain strings instead.
-`String::New()` has been removed, use `String::NewFromUtf8()` instead.
-`Persistent` objects no longer inherit from `Handle` and cannot be instantiated with another object. Instead, the `Persistent` should simply be declared, e.g. `Persistent<Type> handle` and then have a `Local` assigned to it with `handle.Reset(isolate, value)`. To get a `Local` from a `Persistent` you must instantiate it as the argument, i.e. `Local::New(Isolate*, Persistent)`.
