v7.0.0-beta.0

• Note: this release has a number of BC breaks, which will only affect you if
  you wrote custom format parsers. See the wiki for more details.
• #326: State objects now have follow() and followAll() methods.
• #322: Add type, status, detail, instance properties to Problem
  class, for better support of [application/problem+json][6]. (@sazzer).
• #327: If a response is received with a Content-Location header, the
  response will now immediately get stored in the cache.
• Support for [draft-dalal-deprecation-header][7]. Ketting will now emit
  warnings if a Deprecation header is detected, and will also provide
  information from the Sunset header and include the uri of the deprecation
  link relation.
• Support for the latest [HAL-Forms][5] features, including target, step,
  min, max, type, minLength, maxLength, placeholder, cols, rows.
• Support multiple HAL Forms, as per the latest spec updates. Before only a
  'default' form was supported.
• Add textarea form field type.
• #324: Only use {cache: 'no-cache'} with .refresh(), not .get().
• Fixed a subtle URL resolving bug in browsers. (Node was not affected).

v6.2.0

• Updated fetch-mw-oauth2, which has a few new features:
  • Fixed a race condition where two 401's in quick succession could result
    in two OAuth2 refresh requests, ultimately causing 1 to fail.
  • Preemptively refresh if we know when the access token will expire.

v6.1.4

• #302: Templated links without template data don't work.

v6.1.3

• Add a getCache() function to Resource, which allows a user to get the
  latest Resource State in a synchronous manner.
• #292: Parse Siren's 'value' property in action fields.
• fetch-mw-oauth2 dependency had a bug related to refreshing tokens. This
  release ships with a version without that bug.

v6.1.2

• Update the fetch-mw-oauth2 dependency, which adds an onAuthError event.

v6.1.1

• state.links.delete() can now take a href argument to delete a specific
  link from its list.
• Improvements in error messaging.
• Upgrade to Webpack 5

v6.1.0

• Large changes in the actions/form system. This should still be considered
  experimental and could cause some minor BC breaks.
• Actions are now effectively a serialization of a HTML form, and it's now
  possible to introspect information such as the target, method,
  contentType, etc.
• Some refactoring in the State objects, simplifiying these significantly.

v6.0.4

• State objects now have an actions() method that return all defined
  actions.

v6.0.3

• #241: Add application/prs.hal-forms+json to Accept header and treat as
  HAL (@reda-alaoui).
• #260: action() could not be successfully called on a HAL action.
  (@reda-alaoui).
• Add action() function to State interface.

v6.0.2

• #248: Parse JSON objects that have an array at the top-level.
• #257: ETag and Last-Modified are now treated as 'Content headers', which
  means they will get returned from getContentHeaders().
