## 2.0.0

### Removals

All API methods that were called directly on `RDStation::Client` (ex: `RDStation::Client.new('rdstation_token', 'auth_token').create_lead(lead_info)`) have been removed. See the [upgrading guide](#Upgrading-to-version-2.0.0) for a comprehensive guide on how to upgrade from version 1.2.x.

### Notable changes

#### RDStation::Client

Now `RDStation::Client` is facade to all available endpoints in the 2.0 API. It needs to be instantiated with an access_token and has accessors to those endpoints. Usage examples:

```ruby
  client = RDStation::Client.new((access_token: 'my_token')
  client.contacts.by_uuid('CONTACT_UUID')
  client.webhooks.all
  client.events.create(my_json_payload)
  client.fields.all
```

`RDStation::Contacts`, `RDStation::Events`, `RDStation::Fields` and `RDStation::Webhooks` are not suposed to be instantiated directly anymore. Use `RDStation::Client` to get them instead.

#### Error handling

Now specific errors are raised for each HTTP status:

- `RDStation::Error::BadRequest` (400)
- `RDStation::Error::Unauthorized` (401)
- `RDStation::Error::Forbidden` (403)
- `RDStation::Error::NotFound` (404)
- `RDStation::Error::MethodNotAllowed` (405)
- `RDStation::Error::NotAcceptable` (406)
- `RDStation::Error::Conflict` (409)
- `RDStation::Error::UnsupportedMediaType` (415)
- `RDStation::Error::UnprocessableEntity` (422)
- `RDStation::Error::InternalServerError` (500)
- `RDStation::Error::NotImplemented` (501)
- `RDStation::Error::BadGateway` (502)
- `RDStation::Error::ServiceUnavailable` (503)
- `RDStation::Error::ServerError` (which is returned for 5xx errors different than 500, 501, 502 or 503)

In case of a Bad Request (400), the following specific errors may be raised (those are subclasses of `RDStation::Error::BadRequest`):
- `RDStation::Error::ConflictingField`
- `RDStation::Error::InvalidEventType`

In cause of Unahtorized (401), the following specific errors may be raised (those are subclasses of `RDStation::Error::Unauthorized`):
- `RDStation::Error::ExpiredAccessToken`
- `RDStation::Error::ExpiredCodeGrant`
- `RDStation::Error::InvalidCredentials`

### Dependencies

`rdstation-ruby-client` now requires `ruby >= 2.0.0`.

## 1.2.1 

### Deprecations

All API methods that were called directly on `RDStation::Client` (ex: `RDStation::Client.new('rdstation_token', 'auth_token').create_lead(lead_info)`) are now deprecated. Those methods call RDSM's 1.3 API and will be removed in the next release.
