- [added] The `Sensors`, `PeopleNowPresentSensor` and `TemperatureSensor`
  structs now derive `Default` (#84)
- [added] Basic support for the new v14 API (#85, #87, #89, #90, #91) This is a
  breaking change since it changes the `api` field of `Status` to

  * Add `xmpp` field to `Keymaster`
  * Rename jabber to xmpp in contact field
  * Add xmpp to contact/keymasters
  * Deprecate contacts.google, issue\_report\_channels, radio\_show,
    spacefed.spacephone and stream keys
  * Add `mumble`, `matrix`, `mastodon` and `gopher` to `Contact`
  * Add `mastodon` field to `Keymaster`
  * Make `state` field optional and disallow `null` for `state.open`
