Notable Changes in 5.0.0:
* buffer: (Breaking) Removed both 'raw' and 'raws' encoding types
from Buffer, these have been deprecated for a long time

3 decimals of accuracy added
* fs:
- fs.readFile*(), fs.writeFile*(), and fs.appendFile*() now also
accept a file descriptor as their first argument
- (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
- (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
* http:
- Fixed a bug where pipelined http requests would stall
- (Breaking) When parsing HTTP, don't add duplicates of the
following headers: Retry-After, ETag, Last-Modified, Server, Age,
Expires.
- (Breaking) The callback argument to OutgoingMessage#setTimeout()
must be a function or a TypeError is thrown
- (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.
* node:
- (Breaking) Deprecated the _linklist module
- (Breaking) Removed require.paths and require.registerExtension(),
both had been previously set to throw Error when accessed
* npm: Upgraded to version 3.3.6 from 2.14.7
* src: (Breaking) Bumped NODE_MODULE_VERSION to 47 from 46
* timers: Attempt to reuse the timer handle for setTimeout().unref().

- (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.
* util:
- (Breaking) util.p() was deprecated for years, and has now been
removed
