+## 2015-08-01, Version 3.0.0, @rvagg
+
+### Notable changes
+
+* **buffer**:
+  - Due to changes in V8, it has been necessary to reimplement `Buffer` on top of V8's `Uint8Array`. While every effort has been made to maintain performance, users are likely to experience a different performance profile depending on how `Buffer` is used. (Trevor Norris) [#1825](https://github.com/nodejs/io.js/pull/1825).
+  - `Buffer` can now take `ArrayBuffer`s as a constructor argument (Trevor Norris) [#2002](https://github.com/nodejs/io.js/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/io.js/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/io.js/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/io.js/pull/1796)
+* **freelist**: Deprecate the undocumented `freelist` core module (Sakthipriyan Vairamani) [#2176](https://github.com/nodejs/io.js/pull/2176).
+* **http**:
+  - 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/io.js/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/io.js/pull/1617).
+* **node**:
+  - `NODE_MODULE_VERSION` has been bumped to `45` to reflect the break in ABI (Rod Vagg) [#2096](https://github.com/nodejs/io.js/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/io.js/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/io.js/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/io.js/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/io.js/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/io.js/pull/2227).
+* **v8**: Upgraded to 4.4.63.26
+  - ES6: Enabled [computed property names](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#Computed_property_names)
+  - 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.
+  - Added support for PPC
+
+### Known issues
+
+See https://github.com/nodejs/io.js/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/io.js/issues/1264).
+* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/io.js/issues/690)
+* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/nodejs/io.js/issues/760).
+* 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/io.js/issues/894)
+* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/io.js/issues/1435).
