Notable changes:

* buffer: (Breaking) Removed both 'raw' and 'raws' encoding types from Buffer,
  these have been deprecated for a long time (Sakthipriyan Vairamani) #2859.
* console: (Breaking) Values reported by console.time() now have 3 decimals of
  accuracy added (Michaël Zasso) #3166.
* fs:
  - fs.readFile*(), fs.writeFile*(), and fs.appendFile*() now also accept a file
    descriptor as their first argument (Johannes Wüller) #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.
  - (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.
* http:
  - Fixed a bug where pipelined http requests would stall (Fedor Indutny) #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.
  - (Breaking) The callback argument to OutgoingMessage#setTimeout() must be a
    function or a TypeError is thrown (James M Snell) #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.
* node:
  - (Breaking) Deprecated the _linklist module (Rich Trott) #3078.
  - (Breaking) Removed require.paths and require.registerExtension(), both had
    been previously set to throw Error when accessed
    (Sakthipriyan Vairamani) #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 for a list of major changes
  (Rebecca Turner) #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.
* 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.
* tls:
  - Added ALPN Support (Shigeki Ohtsu) #2564.
  - TLS options can now be passed in an object to createSecurePair()
    (Коренберг Марк) #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.
* util:
  - (Breaking) util.p() was deprecated for years, and has now been removed
    (Wyatt Preul) #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)`
