## 2.0.0 - 2014-12-16

### Backward incompatible changes

- [#448] Removes `doorkeeper_for` helper. Now we use
  `before_action :doorkeeper_authorize!`.
- [#469] Allow client applications to restrict the set of allowable scopes.
  Fixes #317. `oauth_applications` relation needs a new `scopes` string column,
  non nullable, which defaults to an empty string. To add the column run:

  ```
  rails generate doorkeeper:application_scopes
  ```

  If you’d rather do it by hand, your ActiveRecord migration should contain:

  ```ruby
  add_column :oauth_applications, :scopes, :string, null: false, default: ‘’
  ```

### Removed deprecations

- Removes `test_redirect_uri` option. It is now called `native_redirect_uri`.
- [#446] Removes `mount Doorkeeper::Engine`. Now we use `use_doorkeeper`.

### Others

- [#484] Performance improvement - avoid performing order_by when not required.
- [#450] When password is invalid in Password Credentials Grant, Doorkeeper
  returned 'invalid_resource_owner' instead of 'invalid_grant', as the spec
  declares. Fixes #444.
- [#452] Allows `revoked_at` to be set in the future, for future expiry.
  Rationale: https://github.com/doorkeeper-gem/doorkeeper/pull/452#issuecomment-51431459
- [#480] For Implicit grant flow, access tokens can now be reused. Fixes #421.
- [#491] Reworks of @jasl's #454 and #478. ORM refactor that allows doorkeeper
  to be extended more easily with unsupported ORMs. It also marks the boundaries
  between shared model code and ORM specifics inside of the gem.
- [#496] Tests with Rails 4.2.
- [#489] Adds `force_ssl_in_redirect_uri` to force the usage of the HTTPS
  protocol in non-native redirect uris.
- [#516] SECURITY: Adds `protect_from_forgery` to `Doorkeeper::ApplicationController`
- [#518] Fix random failures in mongodb.
