-### Unreleased

+### 4.8.0 - 2021-04-29
+
+* enhancements
+  * Devise now enables the upgrade of OmniAuth 2+. Previously Devise would raise an error if you'd try to upgrade. Please note that OmniAuth 2 is considered a security upgrade and recommended to everyone. You can read more about the details (and possible necessary changes to your app as part of the upgrade) in [their release notes](https://github.com/omniauth/omniauth/releases/tag/v2.0.0). [Devise's OmniAuth Overview wiki](https://github.com/heartcombo/devise/wiki/OmniAuth:-Overview) was also updated to cover OmniAuth 2.0 requirements.
+    - Note that the upgrade required Devise shared links that initiate the OmniAuth flow to be changed to `method: :post`, which is now a requirement for OmniAuth, part of the security improvement. If you have copied and customized the Devise shared links partial to your app, or if you have other links in your app that initiate the OmniAuth flow, they will have to be updated to use `method: :post`, or changed to use buttons (e.g. `button_to`) to work with OmniAuth 2. (if you're using links with `method: :post`, make sure your app has `rails-ujs` or `jquery-ujs` included in order for these links to work properly.)
+    - As part of the OmniAuth 2.0 upgrade you might also need to add the [`omniauth-rails_csrf_protection`](https://github.com/cookpad/omniauth-rails_csrf_protection) gem to your app if you don't have it already. (and you don't want to roll your own code to verify requests.) Check the OmniAuth v2 release notes for more info.
+  * Introduce `Lockable#reset_failed_attempts!` model method to reset failed attempts counter to 0 after the user signs in.
+    - This logic existed inside the lockable warden hook and is triggered automatically after the user signs in. The new model method is an extraction to allow you to override it in the application to implement things like switching to a write database if you're using the new multi-DB infrastructure from Rails for example, similar to how it's already possible with `Trackable#update_tracked_fields!`.
+  * Add support for Ruby 3.
+  * Add support for Rails 6.1.
+  * Move CI to GitHub Actions.
+
+* deprecations

+  * The second argument of `DatabaseAuthenticatable`'s `#update_with_password` and `#update_without_password` is deprecated and will be removed in the next major version. It was added to support a feature deprecated in Rails 4, so you can safely remove it from your code. (by @ihatov08)
+  * The `DeviseHelper.devise_error_messages!` is deprecated and will be removed in the next major version. Use the `devise/shared/error_messages` partial instead. (by @mracos)

The authentication can be done both through POST requests or HTTP Basic Authentication.

-* [Confirmable](http://www.rubydoc.info/github/plataformatec/devise/master/Devise/Models/Confirmable): sends emails with confirmation instructions and verifies whether an account is already confirmed during sign in.
-* [Recoverable](http://www.rubydoc.info/github/plataformatec/devise/master/Devise/Models/Recoverable): resets the user password and sends reset instructions.

-* [Validatable](http://www.rubydoc.info/github/plataformatec/devise/master/Devise/Models/Validatable): provides validations of email and password. It's optional and can be customized, so you're able to define your own validations.

 You will usually want to write tests for your changes.  To run the test suite, go into Devise's top-level directory and run `bundle install` and `bin/test`.
 Devise works with multiple Ruby and Rails versions, and ActiveRecord and Mongoid ORMs, which means you can run the test suite with some modifiers: `DEVISE_ORM` and `BUNDLE_GEMFILE`.
 
 ### DEVISE_ORM
-Since Devise support both Mongoid and ActiveRecord, we rely on this variable to run specific code for each ORM.
-The default value of `DEVISE_ORM` is `active_record`. To run the tests for mongoid, you can pass `mongoid`:

-## Additional information
+### Rails API Mode
 
-### Heroku
+Rails 5+ has a built-in [API Mode](https://edgeguides.rubyonrails.org/api_app.html) which optimizes Rails for use as an API (only). Devise is _somewhat_ able to handle applications that are built in this mode without additional modifications in the sense that it should not raise exceptions and the like. But some issues may still arise during `development`/`testing`, as we still don't know the full extent of this compatibility. (For more information, see [issue #4947](https://github.com/heartcombo/devise/issues/4947/))
 
-Using Devise on Heroku with Ruby on Rails 3.2 requires setting:
+#### Supported Authentication Strategies
+API-only applications don't support browser-based authentication via cookies, which is devise's default. Yet, devise can still provide authentication out of the box in those cases with the `http_authenticatable` strategy, which uses HTTP Basic Auth and authenticates the user on each request. (For more info, see this wiki article for [How To: Use HTTP Basic Authentication](https://github.com/heartcombo/devise/wiki/How-To:-Use-HTTP-Basic-Authentication))
+
+The devise default for HTTP Auth is disabled, so it will need to be enabled in the devise initializer for the database strategy:
 
 ```ruby
-config.assets.initialize_on_precompile = false
+config.http_authenticatable = [:database]
 ```
 
-Read more about the potential issues at http://guides.rubyonrails.org/asset_pipeline.html
+This restriction does not limit you from implementing custom warden strategies, either in your application or via gem-based extensions for devise.
+A common authentication strategy for APIs is token-based authentication. For more information on extending devise to support this type of authentication and others, see the wiki article for [Simple Token Authentication Examples and alternatives](https://github.com/heartcombo/devise/wiki/How-To:-Simple-Token-Authentication-Example#alternatives) or this blog post on [Custom authentication methods with Devise](http://blog.plataformatec.com.br/2019/01/custom-authentication-methods-with-devise/).
+
+#### Testing
+API Mode changes the order of the middleware stack, and this can cause problems for `Devise::Test::IntegrationHelpers`. This problem usually surfaces as an ```undefined method `[]=' for nil:NilClass``` error when using integration test helpers, such as `#sign_in`. The solution is simply to reorder the middlewares by adding the following to test.rb:
+
+```ruby
+Rails.application.config.middleware.insert_before Warden::Manager, ActionDispatch::Cookies
+Rails.application.config.middleware.insert_before Warden::Manager, ActionDispatch::Session::CookieStore
+```
+
+For a deeper understanding of this, review [this issue](https://github.com/heartcombo/devise/issues/4696).
+
+Additionally be mindful that without views supported, some email-based flows from Confirmable, Recoverable and Lockable are not supported directly at this time.
