* **node**: --no-browser-globals configure flag (Fedor Indutny) [#5853](https://github.com/nodejs/node/pull/5853)
* **npm**: Upgrade to v3.8.3. Fixes a security flaw in the use of authentication tokens in HTTP requests that
  would allow an attacker to set up a server that could collect tokens from users of the command-line interface.
  Authentication tokens have previously been sent with every request made by the CLI for logged-in users,
  regardless of the destination of the request. This update fixes this by only including those tokens for requests
  made against the registry or registries used for the current install. (Forrest L Norvell) [npm/node#6](https://github.com/npm/node/pull/6)

## 2016-03-08, Version 5.8.0 (Stable), @Fishrock123

### Notable changes

* **child_process**: `send()` now accepts an options parameter (cjihrig) [#5283](https://github.com/nodejs/node/pull/5283).
  - Currently the only option is `keepOpen`, which keeps the underlying socket open after the message is sent.
* **constants**: `ENGINE_METHOD_RSA` is now correctly exposed (Sam Roberts) [#5463](https://github.com/nodejs/node/pull/5463).
* Fixed two regressions which originated in v5.7.0:
  - **http**: Errors inside of http client callbacks now propagate correctly (Trevor Norris) [#5591](https://github.com/nodejs/node/pull/5591).
  - **path**: Fixed normalization of absolute paths (Evan Lucas) [#5589](https://github.com/nodejs/node/pull/5589).
* **repl**: `start()` no longer requires an options parameter (cjihrig) [#5388](https://github.com/nodejs/node/pull/5388).
* **util**: Improved `format()` performance 50-300% (Evan Lucas) [#5360](https://github.com/nodejs/node/pull/5360).

## 2016-03-02, Version 5.7.1 (Stable), @Fishrock123

### Notable changes

* **governance**: The Core Technical Committee (CTC) added four new members to help guide Node.js core development: Evan Lucas, Rich Trott, Ali Ijaz Sheikh and Сковорода Никита Андреевич (Nikita Skovoroda).
* **openssl**: Upgrade from 1.0.2f to 1.0.2g (Ben Noordhuis) [#5507](https://github.com/nodejs/node/pull/5507).
  - Fix a double-free defect in parsing malformed DSA keys that may potentially be used for DoS or memory corruption attacks. It is likely to be very difficult to use this defect for a practical attack and is therefore considered low severity for Node.js users. More info is available at [CVE-2016-0705](https://www.openssl.org/news/vulnerabilities.html#2016-0705).
  - Fix a defect that can cause memory corruption in certain very rare cases relating to the internal `BN_hex2bn()` and `BN_dec2bn()` functions. It is believed that Node.js is not invoking the code paths that use these functions so practical attacks via Node.js using this defect are _unlikely_ to be possible. More info is available at [CVE-2016-0797](https://www.openssl.org/news/vulnerabilities.html#2016-0797).
  - Fix a defect that makes the _[CacheBleed Attack](https://ssrg.nicta.com.au/projects/TS/cachebleed/)_ possible. This defect enables attackers to execute side-channel attacks leading to the potential recovery of entire RSA private keys. It only affects the Intel Sandy Bridge (and possibly older) microarchitecture when using hyper-threading. Newer microarchitectures, including Haswell, are unaffected. More info is available at [CVE-2016-0702](https://www.openssl.org/news/vulnerabilities.html#2016-0702).
* Fixed several regressions that appeared in v5.7.0:
  - **`path.relative()`**:
    - Output is no longer unnecessarily verbose (Brian White) [#5389](https://github.com/nodejs/node/pull/5389).
    - Resolving UNC paths on Windows now works correctly (Owen Smith) [#5456](https://github.com/nodejs/node/pull/5456).
    - Resolving paths with prefixes now works correctly from the root directory (Owen Smith) [#5490](https://github.com/nodejs/node/pull/5490).
  - **url**: Fixed an off-by-one error with `parse()` (Brian White) [#5394](https://github.com/nodejs/node/pull/5394).
  - **dgram**: Now correctly handles a default address case when offset and length are specified (Matteo Collina) [#5407](https://github.com/nodejs/node/pull/5407).

## 2016-02-23, Version 5.7.0 (Stable), @rvagg

### Notable changes

* **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](https://nodejs.org/api/buffer.html#buffer_buf_fill_value_offset_end_encoding) for details on how this works. (Trevor Norris) [#4935](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/4598)
* **http_parser**: Update to http-parser 2.6.2 to fix an unintentionally strict limitation of allowable header characters (James M Snell) [#5237](https://github.com/nodejs/node/pull/5237)
* **dgram**: `socket.send()` now supports accepts an array of Buffers or Strings as the first argument. See the [API docs](https://nodejs.org/download/nightly/v6.0.0-nightly201602102848f84332/docs/api/dgram.html#dgram_socket_send_msg_offset_length_port_address_callback) for details on how this works. (Matteo Collina) [#4374](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/4337)
* **net**: Added a `listening` Boolean property to `net` and `http` servers to indicate whether the server is listening for connections. (José Moreira) [#4743](https://github.com/nodejs/node/pull/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](https://github.com/nodejs/node/pull/4507)
* **tls**: Add a new `tlsSocket.getProtocol()` method to get the negotiated TLS protocol version of the current connection. (Brian White) [#4995](https://github.com/nodejs/node/pull/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](https://nodejs.org/api/vm.html#vm_new_vm_script_code_options) for details. (Fedor Indutny) [#4777](https://github.com/nodejs/node/pull/4777)
* **performance**: Improvements in:
  - `process.nextTick()` (Ruben Bridgewater) [#5092](https://github.com/nodejs/node/pull/5092)
  - `path` module (Brian White) [#5123](https://github.com/nodejs/node/pull/5123)
  - `querystring` module (Brian White) [#5012](https://github.com/nodejs/node/pull/5012)
  - `streams` module when processing small chunks (Matteo Collina) [#4354](https://github.com/nodejs/node/pull/4354)

## 2016-02-09, Version 5.6.0 (Stable), @jasnell

This is an important security release. All Node.js users should consult the security release summary at nodejs.org for details on patched vulnerabilities.

### Notable changes

* **http**: fix defects in HTTP header parsing for requests and responses that can allow request smuggling (CVE-2016-2086) or response splitting (CVE-2016-2216). HTTP header parsing now aligns more closely with the HTTP spec including restricting the acceptable characters.
* **http-parser**: upgrade from 2.6.0 to 2.6.1
* **npm**: upgrade npm from 3.3.12 to 3.6.0 (Rebecca Turner) [#4958](https://github.com/nodejs/node/pull/4958)
* **openssl**: upgrade from 1.0.2e to 1.0.2f. To mitigate against the Logjam attack, TLS clients now reject Diffie-Hellman handshakes with parameters shorter than 1024-bits, up from the previous limit of 768-bits.

  - **assert**: deepEqual is now speedier when comparing TypedArrays (Claudio Rodriguez) [#4330](https://github.com/nodejs/node/pull/4330).
  - **lib**: Use arrow functions instead of bind where possible (Minwoo Jung) [node#3622](https://github.com/nodejs/node/pull/3622).
  - **node**: Improved accessor perf of `process.env` (Trevor Norris) [#3780](https://github.com/nodejs/node/pull/3780).
  - **node**: Improved performance of `process.hrtime()` (Trevor Norris) [#3780](https://github.com/nodejs/node/pull/3780), (Evan Lucas) [#4484](https://github.com/nodejs/node/pull/4484).
  - **node**: Improved GetActiveHandles performance (Trevor Norris) [#3780](https://github.com/nodejs/node/pull/3780).
  - **util**: Use faster iteration in `util.format()` (Jackson Tian) [#3964](https://github.com/nodejs/node/pull/3964).

### 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).

  - `Buffer.prototype.includes()` has been added to keep parity with TypedArrays. (Alexander Martin) [#3567](https://github.com/nodejs/node/pull/3567).
* **domains**:
  - Fix handling of uncaught exceptions. (Julien Gilli) [#3654](https://github.com/nodejs/node/pull/3654).
* **https**:
  - Added support for disabling session caching. (Fedor Indutny) [#4252](https://github.com/nodejs/node/pull/4252).
* **repl**:
  - Allow third party modules to be imported using `require()`. This corrects a regression from 5.2.0. (Ben Noordhuis) [#4215](https://github.com/nodejs/node/pull/4215).
* **deps**:
  - Upgrade libuv to 1.8.0. (Saúl Ibarra Corretgé) [#4276](https://github.com/nodejs/node/pull/4276).


### 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).

## 2015-12-09, Version 5.2.0 (Stable), @rvagg

### Notable changes

* **build**:
  - 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).
  - Properly enable V8 snapshots by default. Due to a configuration error, snapshots have been kept off by default when the intention is for the feature to be enabled. (Fedor Indutny) [#3962](https://github.com/nodejs/node/pull/3962).
* **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).
  - Multiple CA certificates can now be passed with the `ca` option to TLS methods as an array of strings or in a single new-line separated string. (Ben Noordhuis) [#4099](https://github.com/nodejs/node/pull/4099)
* **tools**: Include a tick processor in core, exposed via the `--prof-process` command-line argument which can be used to process V8 profiling output files generated when using the `--prof` command-line argument. (Matt Loring) [#4021](https://github.com/nodejs/node/pull/4021).


### 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)

* 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).

## 2015-12-04, Version 5.1.1 (Stable), @rvagg

### Notable changes

* **http**: Fix CVE-2015-8027, a bug whereby an HTTP socket may no longer have a parser associated with it but a pipelined request attempts to trigger a pause or resume on the non-existent parser, a potential denial-of-service vulnerability. (Fedor Indutny)
* **openssl**: Upgrade to 1.0.2e, containing fixes for:
  - CVE-2015-3193 "BN_mod_exp may produce incorrect results on x86_64", an attack may be possible against a Node.js TLS server using DHE key exchange. Details are available at <http://openssl.org/news/secadv/20151203.txt>.
  - CVE-2015-3194 "Certificate verify crash with missing PSS parameter", a potential denial-of-service vector for Node.js TLS servers using client certificate authentication; TLS clients are also impacted. Details are available at <http://openssl.org/news/secadv/20151203.txt>.
  (Shigeki Ohtsu) [#4134](https://github.com/nodejs/node/pull/4134)
* **v8**: Backport fix for CVE-2015-6764, a bug in `JSON.stringify()` that can result in out-of-bounds reads for arrays. (Ben Noordhuis)

### 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).

<a id="5.1.0"></a>
## 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 (Minqi Pan) [#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).

## 2015-10-29, Version 5.0.0 (Stable), @rvagg

### Notable Changes

* **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).
