v6.0.0-alpha.3

• Resources implement EventEmitter, and can emit stale, update and
  delete events.
• The 'body' property on State is now 'data'
• #141: Added head() function and ability to follow links just through HEAD
  methods via the Link header.
• Added a NeverCache and ShortCache if automatically storing every State
  object until invalidation is not desired.
• When calling put() with a new State object, that object will now be placed
  in cache.
• When refreshing, fetch() is now given the 'reload' cache setting, so that
  refresh() is a true Refresh, even with a browser cache.
• #130: Support relative bookmark URIs when using Ketting in a browser.
• Siren was not correctly parsed.
• Add .clone() method to all State object.

v6.0.0-alpha.2

• State is now exported.
• #184: Added a new postFollow() function that takes over the role of
  post(). post() is now intended for RPC-like operations and form
  submissions.

v6.0.0-alpha.1

• Re-release. The build contained a few older files that weren't meant to be
  packaged.

v6.0.0-alpha.0

• Big BC-breaking rewrite. Changes are numerous, but the important ones are
  listed here.
• Resource.get() now returns a State object instead of just a response
  body. This object has methods to make it easier to manipulate and get
  information about the response, including links. It's also a stable,
  non-async object.
• Ketting class is now called Client. It's still exposed as Ketting
  as well for BC purposes.
• Client.getResource() has been removed. Use Client.go() instead.
• A HTTP Fetch middleware system has been added, for easier manipulation of
  requests and responses. Middlewares can be added for every request, or
  for specific origins (domains).
• All authentication settings have been removed, and reimplemented as
  fetch middlewares. They take roughly the same options, but the setup
  has changed.
• Resource.get(), Resource.put(), etc. can now all take custom headers
  and other options to manipulate the request.
• In the past you could just send a body with Resource.post(), .put(),
  .patch(). Now this body must be a wrapped in an object with at least a .body
  property. This is an annoying BC break but will allow for more flexibility
  that was previous impossible.
• Proper support for 'binary' resources.
• Hal Links will now be reserialized on put().
• Resource.link, Resource.links and Resource.hasLink has been deprecated,
  but not removed.
• Link objects are now a simple typescript type, and no longer implemented
  as a class.
• FollowerOne is now FollowPromiseOne and FollowerMany is now
  FollowPromiseMany.
• All things called Representor has been removed, and rewritten with
  a completely new API. A HAL representor is now a HalState.
• #175: Nested embedded items are now also placed in the cache.

v5.2.1

• Use the title= attribute from the HTTP Link header, if it exists.

v5.2.0

• Added 'finally()' to custom follower promises.
• All representors are now exported in the representor namespace.

v5.1.2

• Correct return type on followAll, so it may be chained with preFetch.
  This was only an issue when doing 'multiple hops'.

v5.1.1

• #173: De-duplicate HAL links if they appear in _embedded and _links.

v5.1.0

• Support for the Collection+json format.
• Added a preferTransclude() method on the Follower objects. This
  automatically adds a Prefer: tranclude="rel" header.

v5.0.1

• Update all dependencies.
