2015-05-31 io.js v2.2.0 Release

PR-URL: nodejs#1808

Notable Changes:

* 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) nodejs#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) nodejs#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 for full details.

 # io.js ChangeLog
 
+## 2015-05-31, Version 2.2.0, @rvagg
+
+### Notable changes
+
+* **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/io.js/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/io.js/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.
+
+### 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) and fix in [#774](https://github.com/nodejs/io.js/issues/774)
+* 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).
