## [4.0.0](https://github.com/recurly/recurly-client-ruby/tree/4.0.0) (2021-03-01)


# Major Version Release

The 4.x major version of the client pairs with the `v2021-02-25` API version. This version of the client and the API contain breaking changes that should be considered before upgrading your integration.

## Breaking Changes in the API
All changes to the core API are documented in the [Developer Portal changelog](https://developers.recurly.com/api/changelog.html#v2021-02-25---current-ga-version)

## Breaking Changes in Client

- Remove `site_id` and `subdomain` from client initializer.  [#624]
- Remove `set_site_id` method from client.  [#627]
- Classify unexpected error responses from Recurly API via an HTTP status code mapping provided in `Recurly::Errors::ERROR_MAP`.  [#616]
- Remove `NetworkError` class. All error classes now extend the `APIError`. This means that the order of multiple rescue blocks will need to be re-considered.  [#616]

    ### 3.x
    
    ```ruby
    rescue Recurly::Errors::ValidationError => ex
      # catch a validation error
    rescue Recurly::Errors::APIError => ex
      # catch a generic api error
    rescue Recurly::Errors::TimeoutError => ex
      # catch a specific network error
    ```
    
    ### 4.x
    
    ```ruby
    rescue Recurly::Errors::ValidationError => ex
      # catch a validation error
    rescue Recurly::Errors::TimeoutError => ex
      # catch a specific network error
    rescue Recurly::Errors::APIError => ex
      # catch a generic api error
    ```

- Rename `InvalidResponseError` to `InvalidContentTypeError`.  [#616]
- Rename `UnavailableError` to `ServiceUnavailableError`.  [#616]
- Reorganize top-level keys of the optional parameters hash to improve clarity and create space for additional options.  [#619]

    ### 3.x
    
    ```ruby
    options = {
      limit: 200,
      headers: {
        'Accept-Language' => 'fr'
      }
    }
    accounts = @client.list_accounts(options)
    ```
    
    ### 4.x
    
    ```ruby
    options = {
      params: {
          limit: 200
      }
      headers: {
        'Accept-Language' => 'fr'
      }
    }
    accounts = @client.list_accounts(options)
    ```
