-### Unreleased
+### 4.9.4 - 2024-04-10
+
+* enhancements
+  * Add support for Ruby 3.3. (no changes needed)
+
+* bug fixes
+  * Respect locale set by controller in failure app. Devise will carry over the current I18n.locale option when triggering authentication, and will wrap the failure app call with it. [#5567](https://github.com/heartcombo/devise/pull/5567)
+
+### 4.9.3 - 2023-10-11
+
+* enhancements
+  * Add support for Rails 7.1.
+  * Add `Devise.deprecator` to integrate with new application deprecators in Rails 7.1. (@soartec-lab, @etiennebarrie)
+
+### 4.9.2 - 2023-04-03
+
+* deprecations
+  * Bring back `Devise.activerecord51?` and deprecate it, in order to avoid breakage with some libraries that apparently relied on it.
+
+### 4.9.1 - 2023-03-31
+
+* enhancements
+  * Allow resource class scopes to override the global configuration for `sign_in_after_reset_password` behaviour. [#5429](https://github.com/heartcombo/devise/pull/5429) [@mattr](https://github.com/mattr)
+  * Refactor conditional dirty tracking logic to a centralized module to simplify usage throughout the codebase. [#5575](https://github.com/heartcombo/devise/pull/5575)
+  * Improve support for Devise in apps with Active Record and Mongoid ORMs loaded, so it does not incorrectly uses new Active Record dirty tracking APIs with a Mongoid Devise model. [#5576](https://github.com/heartcombo/devise/pull/5576)
+
+* bug fixes
+  * Failure app will respond with configured `redirect_status` instead of `error_status` if the recall app returns a redirect status (300..399) [#5573](https://github.com/heartcombo/devise/pull/5573)
+  * Fix frozen string exception in validatable. [#5563](https://github.com/heartcombo/devise/pull/5563) [#5465](https://github.com/heartcombo/devise/pull/5465) [@mameier](https://github.com/mameier)
+
+### 4.9.0 - 2023-02-17
+
+* enhancements
+  * Add support for Ruby 3.1/3.2.
+  * Add support for Hotwire + Turbo, default in Rails 7+.
+    * Devise uses the latest `responders` version (v3.1.0 or higher), which allows configuring the status used for validation error responses (`error_status`) and for redirects after POST/PUT/PATCH/DELETE requests (`redirect_status`). For backwards compatibility, Devise keeps `error_status` as `:ok` which returns a `200 OK` response, and `redirect_status` to `:found` which returns a `302 Found` response, but you can configure it to return `422 Unprocessable Entity` and `303 See Other` respectively, to match the behavior expected by Hotwire/Turbo:
+
+      ```ruby
+      # config/initializers/devise.rb
+      Devise.setup do |config|
+        # ...
+        config.responder.error_status = :unprocessable_entity
+        config.responder.redirect_status = :see_other
+        # ...
+      end
+      ```
+
+      These configs are already generated by default with new apps, and existing apps may opt-in as described above. Trying to set these with an older version of `responders` will issue a warning and have no effect, so please upgrade the `responders` version if you're upgrading Devise for this integration. Note that these defaults may change in future versions of Devise, to better match the Rails + Hotwire/Turbo defaults across the board.
+    * If you have a custom responder set on your application and expect it to affect Devise as well, you may need to override the Devise responder entirely with `config.responder = MyApplicationResponder`, so that it uses your custom one. The main reason Devise uses a custom responder is to be able to configure the statuses as described above, but you can also change that config on your own responder if you want. Check the `responders` readme for more info on that.
+    * If you have created a custom responder and/or failure app just to customize responses for better Hotwire/Turbo integration, they should no longer be necessary.
+    * `:turbo_stream` is now treated as a navigational format, so it works like HTML navigation when using Turbo. Note: if you relied on `:turbo_stream` to be treated as a non-navigational format before, you can reconfigure your `navigational_formats` in the Devise initializer file to exclude it.
+    * OmniAuth "Sign in with" links were changed to buttons that generate HTML forms with method=POST, instead of using link + method=POST that required rails-ujs to work. Since rails-ujs is no longer the default for new Rails apps, this allows the OmniAuth buttons to work in any scenario, with or without rails-ujs and/or Turbo. This only affects apps that are using the default `devise/shared/_links.html.erb` partial from Devise with OmniAuth enabled.
+    * The "Cancel my account" button was changed to include the `data-turbo-confirm` option, so that it works with both rails-ujs and Turbo by default.
+    * Devise does not provide "sign out" links/buttons in its shared views, but if you're using `sign_out_via` with `:delete` (the default), and are using links with `method: :delete`, those need to be updated with `data: { turbo_method: :delete }` instead for Turbo.
+    * Check [this upgrade guide](https://github.com/heartcombo/devise/wiki/How-To:-Upgrade-to-Devise-4.9.0-[Hotwire-Turbo-integration]) for more detailed information.
+
+### 4.8.1 - 2021-12-16
+
+* enhancements
+  * Add support for Rails 7.0. Please note that Turbo integration is not fully supported by Devise yet.
+
+### 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
+  * `Devise::Models::Authenticatable::BLACKLIST_FOR_SERIALIZATION` is deprecated in favor of `Devise::Models::Authenticatable::UNSAFE_ATTRIBUTES_FOR_SERIALIZATION` (@hanachin)

+
+### 4.6.1 - 2019-02-11
+
+* bug fixes
+  * Check if `root_path` is defined with `#respond_to?` instead of `#present` (by @tegon)

+  * Fix undefined method `rails5?` for Devise::Test:Module (by @tegon)
+  * Fix: secret key was being required to be set inside credentials on Rails 5.2 (by @tegon)

+### 4.4.2 - 2018-03-15
+
+* enhancements
+  * Support for :credentials on Rails v5.2.x. (by @gencer)
+  * Improve documentation about the test suite. (by @tegon)
+  * Test with Rails 5.2.rc1 on Travis. (by @jcoyne)
+  * Allow test with Rails 6. (by @Fudoshiki)
+  * Creating a new section for controller configuration on `devise.rb` template (by @Danilo-Araujo-Silva)
+
+* bug fixes
+  * Preserve content_type for unauthenticated tests (by @gmcnaughton)
+  * Check if the resource is persisted in `update_tracked_fields!` instead of performing validations (by @tegon)
+  * Revert "Replace log_process_action to append_info_to_payload" (by @tegon)
+
+### 4.4.1 - 2018-01-23
+
+* bug fixes
+  * Ensure Gemspec is loaded as utf-8. (by @segiddins)
+  * Fix `ActiveRecord` check on `Confirmable`. (by @tegon)
+  * Fix `signed_in?` docs without running auth hooks. by (@machty)
+
+### 4.4.0 - 2017-12-29
+
+* enhancements
+  * Add `frozen_string_literal` pragma comment to all Ruby files. (by @pat)
+  * Use `set_flash_method!` instead of `set_flash_method` in `Devise::OmniauthCallbacksController#failure`. (by @saichander17)
+  * Clarify how `store_location_for` modifies URIs. (by @olivierlacan)
+  * Move `failed_attempts` increment into its own function. by (@mobilutz)

+  * Validations were being ignored on singup in the `Trackable#update_tracked_fields!` method. (by @AshleyFoster)
+  * Do not modify options for `#serializable_hash`. (by @guigs)
+  * Email confirmations were being sent on sign in/sign out for application using `mongoid` and `mongoid-paperclip` gems. This is because previously we were checking if a model is from Active Record by checking if the method `after_commit` was defined - since `mongoid` doesn' have one - but `mongoid-paperclip` gem does define one, which cause this issue. (by @fjg)
+
+### 4.3.0 - 2017-05-14
+
+* Enhancements
+  * Dependency support added for Rails 5.1.x.
+
+### 4.2.1 - 2017-03-15
+
+* removals
+  * `Devise::Mailer#scope_name` and `Devise::Mailer#resource` are now protected
+    methods instead of public.
+* bug fixes
+  * Attempt to reset password without the password field in the request now results in a `:blank` validation error.
+    Before this change, Devise would accept the reset password request and log the user in, without validating/changing
+    the password. (by @victor-am)
+  * Confirmation links now expire based on UTC time, working properly when using different timezones. (by @jjuliano)
+* enhancements
+  * Notify the original email when it is changed with a new `Devise.send_email_changed_notification` setting.
+    When using `reconfirmable`, the notification will be sent right away instead of when the unconfirmed email is confirmed.
+    (original change by @ethirajsrinivasan)
+
+### 4.2.0 - 2016-07-01
+
+* removals
+  * Remove the deprecated `Devise::ParameterSanitizer` API from Devise 3.
+    Please use the `#permit` and `#sanitize` methods over `#for`.
+  * Remove the deprecated OmniAuth URL helpers. Use the fully qualified helpers
+    (`user_facebook_omniauth_authorize_path`) over the scope based helpers
+    ( `user_omniauth_authorize_path(:facebook)`).
+  * Remove the `Devise.bcrypt` method, use `Devise::Encryptor.digest` instead.
+  * Remove the `Devise::Models::Confirmable#confirm!` method, use `confirm` instead.
+  * Remove the `Devise::Models::Recoverable#reset_password!` method, use `reset_password` instead.
+  * Remove the `Devise::Models::Recoverable#after_password_reset` method.
+* bug fixes
+  * Fix an `ActionDispatch::IllegalStateError` when testing controllers with Rails 5 rc 2(by @hamadata).
+  * Use `ActiveSupport.on_load` hooks to include Devise on `ActiveRecord` and `Mongoid`,
+    avoiding autoloading these constants too soon (by @lucasmazza, @rafaelfranca).
+* enhancements
+  * Display the minimum password length on `registrations/edit` view (by @Yanchek99).
+  * You can disable Devise's routes reloading on boot by through the `reload_routes = false` config.
+    This can reduce the time taken to boot the application but it might trigger
+    some errors if you application (mostly your controllers) requires that
+    Devise mappings be loaded during boot time (by @sidonath).
+  * Added `Devise::Test::IntegrationHelpers` to bypass the sign in process using
+    Warden test API (by @lucasmazza).
+  * Define `inspect` in `Devise::Models::Authenticatable` to help ensure password hashes
+    aren't included in exceptions or otherwise accidentally serialized (by @tkrajcar).
+  * Add missing support of `Rails.application.config.action_controller.relative_url_root` (by @kosdiamantis).
+* deprecations
+  * `Devise::TestHelpers` is deprecated in favor of `Devise::Test::ControllerHelpers`
+    (by @lucasmazza).
+  * The `sign_in` test helper has changed to use keyword arguments when passing
+    a scope. `sign_in :admin, users(:alice)` should be rewritten as
+    `sign_in users(:alice), scope: :admin` (by @lucasmazza).
+  * The option `bypass` of `Devise::Controllers::SignInOut#sign_in` method is
+    deprecated in favor of `Devise::Controllers::SignInOut#bypass_sign_in`
+    method (by @ulissesalmeida).
+
+### 4.1.1 - 2016-05-15
+
+* bug fixes
+  * Fix overwriting the remember_token when a valid one already exists (by @ralinchimev).
+
+### 4.1.0
+
+* bug fixes
+  * Fix race condition of sending the confirmation instructions e-mail using background jobs.
+    Using the previous `after_create` callback, the e-mail can be sent before
+    the record be committed on database, generating a `ActiveRecord::NotFound` error.
+    Now the confirmation e-mail will be only sent after the database commit,
+    using the `after_commit` callback.
+    It may break your test suite on Rails 4 if you are testing the sent e-mails
+    or enqueued jobs using transactional fixtures enabled or `DatabaseCleaner` with `transaction` strategy.
+    You can easily fix your test suite using the gem
+    [test_after_commit](https://github.com/grosser/test_after_commit). For example, put in your Gemfile:
+
+    ```ruby
+      gem 'test_after_commit', :group => :test
+    ```
+
+    On Rails 5 `after_commit` callbacks are triggered even using transactional
+    fixtures, then this fix will not break your test suite. If you are using `DatabaseCleaner` with the `deletion` or `truncation` strategies it may not break your tests. (by @allenwq)
+  * Fix strategy checking in `Lockable#unlock_strategy_enabled?` for `:none` and
+  `:undefined` strategies. (by @f3ndot)
+* features
+  * Humanize authentication keys in failure flash message (by @byzg)
+    When you are configuring the translations of `devise.failure.invalid`, the
+    `authentication_keys` is translated now.
+* deprecations
+  * Remove code supporting old session serialization format (by @fphilipe).
+  * Now the `email_regexp` default uses a more permissive regex:
+    `/\A[^@\s]+@[^@\s]+\z/` (by @kimgb)
+  * Now the `strip_whitespace_keys` default is `[:email]` (by @ulissesalmeida)
+  * Now the `reconfirmable` default is `true` (by @ulissesalmeida)
+  * Now the `skip_session_storage` default is `[:http_auth]` (by @ulissesalmeida)
+  * Now the `sign_out_via` default is `:delete` (by @ulissesalmeida)
+* improvements
+  * Avoids extra computation of friendly token for confirmation token (by @sbc100)
+

-### Please read before contributing
+# How to contribute to Devise
 
-1) Do not post questions in the issues tracker. If you have any questions about Devise, search the [Wiki](https://github.com/plataformatec/devise/wiki) or use the [Mailing List](https://groups.google.com/group/plataformatec-devise) or [Stack Overflow](http://stackoverflow.com/questions/tagged/devise).
+Thanks for your interest on contributing to Devise! Here are a few general
+guidelines on contributing and reporting bugs to Devise that we ask you to
+take a look first. Notice that all of your interactions in the project are
+expected to follow our [Code of Conduct](CODE_OF_CONDUCT.md).
 
-2) If you find a security bug, **DO NOT** submit an issue here. Please send an e-mail to [opensource@plataformatec.com.br](mailto:opensource@plataformatec.com.br) instead.
+## Reporting Issues
 
-3) Do a small search on the issues tracker before submitting your issue to see if it was already reported / fixed.
+Before reporting a new issue, please be sure that the issue wasn't already
+reported or fixed by searching on GitHub through our [issues](https://github.com/heartcombo/devise/issues).
 
-4) When reporting an issue, include Rails, Devise and Warden versions. If you are getting exceptions, please include the full backtrace.
+When creating a new issue, be sure to include a **title and clear description**,
+as much relevant information as possible, and either a test case example or
+even better a **sample Rails app that replicates the issue** - Devise has a lot
+of moving parts and it's functionality can be affected by third party gems, so
+we need as much context and details as possible to identify what might be broken
+for you. We have a [test case template](guides/bug_report_templates/integration_test.rb)
+that can be used to replicate issues with minimal setup.
 
-5) Notice that all of your interactions in the project are expected to follow our [Code of Conduct](CODE_OF_CONDUCT.md)
+Please do not attempt to translate Devise built in views. The views are meant
+to be a starting point for fresh apps and not production material - eventually
+all applications will require custom views where you can write your own copy and
+translate it if the application requires it . For historical references, please look into closed
+[Issues/Pull Requests](https://github.com/heartcombo/devise/issues?q=i18n) regarding
+internationalization.
 
-That's it! The more information you give, the easier it becomes for us to track it down and fix it.
-Ideally, you should provide an application that reproduces the error or a test case to Devise's suite.
+Avoid opening new issues to ask questions in our issues tracker. Please go through
+the project wiki, documentation and source code first, or try to ask your question
+on [Stack Overflow](http://stackoverflow.com/questions/tagged/devise).
 
-Thanks!
+**If you find a security bug, do not report it through GitHub. Please send an
+e-mail to [heartcombo@googlegroups.com](mailto:heartcombo@googlegroups.com)
+instead.**
+
+## Sending Pull Requests
+
+Before sending a new Pull Request, take a look on existing Pull Requests and Issues
+to see if the proposed change or fix has been discussed in the past, or if the
+change was already implemented but not yet released.
+
+We expect new Pull Requests to include enough tests for new or changed behavior,
+and we aim to maintain everything as most backwards compatible as possible,
+reserving breaking changes to be ship in major releases when necessary - you
+can wrap the new code path with a setting toggle from the `Devise` module defined
+as `false` by default to require developers to opt-in for the new behavior.
+
+If your Pull Request includes new or changed behavior, be sure that the changes
+are beneficial to a wide range of use cases or it's an application specific change
+that might not be so valuable to other applications. Some changes can be introduced
+as a new `devise-something` gem instead of belonging to the main codebase.
+
+When adding new settings, you can take advantage of the [`Devise::Models.config`](https://github.com/heartcombo/devise/blob/245b1f9de0b3386b7913e14b60ea24f43b77feb0/lib/devise/models.rb#L13-L50) method to add class and instance level fallbacks
+to the new setting.
+
+We also welcome Pull Requests that improve our existing documentation (both our
+`README.md` and the RDoc sections in the source code) or improve existing rough
+edges in our API that might be blocking existing integrations or 3rd party gems.
+
+## Other ways to contribute
+
+We welcome anyone that wants to contribute to Devise to triage and reply to
+open issues to help troubleshoot and fix existing bugs on Devise. Here is what
+you can do:
+
+* Help ensure that existing issues follows the recommendations from the
+_[Reporting Issues](#reporting-issues)_ section, providing feedback to the issue's
+author on what might be missing.
+* Review and update the existing content of our [Wiki](https://github.com/heartcombo/devise/wiki)
+with up to date instructions and code samples - the wiki was grown with several
+different tutorials and references that we can't keep track of everything, so if
+there is a page that showcases an integration or customization that you are
+familiar with feel free to update it as necessary.
+* Review existing Pull Requests, and testing patches against real existing
+applications that use Devise.
+
+Thanks again for your interest on contributing to the project!

 It's composed of 10 modules:
 
-* [Database Authenticatable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/DatabaseAuthenticatable): hashes and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.
-* [Omniauthable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Omniauthable): adds OmniAuth (https://github.com/intridea/omniauth) support.
-* [Confirmable](http://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://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Recoverable): resets the user password and sends reset instructions.
-* [Registerable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Registerable): handles signing up users through a registration process, also allowing them to edit and destroy their account.
-* [Rememberable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Rememberable): manages generating and clearing a token for remembering the user from a saved cookie.
-* [Trackable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Trackable): tracks sign in count, timestamps and IP address.
-* [Timeoutable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Timeoutable): expires sessions that have not been active in a specified period of time.
-* [Validatable](http://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.
-* [Lockable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Lockable): locks an account after a specified number of failed sign-in attempts. Can unlock via email or after a specified time period.

+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 supports 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`:
+```
+DEVISE_ORM=mongoid bin/test
+
+==> Devise.orm = :mongoid
+```
+When running the tests for Mongoid, you will need to have a MongoDB server (version 2.0 or newer) running on your system.
+
+Please note that the command output will show the variable value being used.
+
+### BUNDLE_GEMFILE
+We can use this variable to tell bundler what Gemfile it should use (instead of the one in the current directory).
+Inside the [gemfiles](https://github.com/heartcombo/devise/tree/main/gemfiles) directory, we have one for each version of Rails we support. When you send us a pull request, it may happen that the test suite breaks using some of them. If that's the case, you can simulate the same environment using the `BUNDLE_GEMFILE` variable.
+For example, if the tests broke using Ruby 2.4.2 and Rails 4.1, you can do the following:
+```bash
+rbenv shell 2.4.2 # or rvm use 2.4.2
+BUNDLE_GEMFILE=gemfiles/Gemfile.rails-4.1-stable bundle install
+BUNDLE_GEMFILE=gemfiles/Gemfile.rails-4.1-stable bin/test
+```
+
+You can also combine both of them if the tests broke for Mongoid:
+```bash
+BUNDLE_GEMFILE=gemfiles/Gemfile.rails-4.1-stable bundle install
+BUNDLE_GEMFILE=gemfiles/Gemfile.rails-4.1-stable DEVISE_ORM=mongoid bin/test
+```

 If you have the need for more deep customization, for instance to also allow "/sign_in" besides "/users/sign_in", all you need to do is create your routes normally and wrap them in a `devise_scope` block in the router:
 
 ```ruby
 devise_scope :user do
-  get "sign_in", to: "devise/sessions#new"
+  get 'sign_in', to: 'devise/sessions#new'
 end
 ```
 
 This way, you tell Devise to use the scope `:user` when "/sign_in" is accessed. Notice `devise_scope` is also aliased as `as` in your router.

+### Hotwire/Turbo
+
+Devise integrates with Hotwire/Turbo by treating such requests as navigational, and configuring certain responses for errors and redirects to match the expected behavior. New apps are generated with the following response configuration by default, and existing apps may opt-in by adding the config to their Devise initializers:
+
+```ruby
+Devise.setup do |config|
+  # ...
+  # When using Devise with Hotwire/Turbo, the http status for error responses
+  # and some redirects must match the following. The default in Devise for existing
+  # apps is `200 OK` and `302 Found` respectively, but new apps are generated with
+  # these new defaults that match Hotwire/Turbo behavior.
+  # Note: These might become the new default in future versions of Devise.
+  config.responder.error_status = :unprocessable_entity
+  config.responder.redirect_status = :see_other
+end
+```
+
+**Important**: these custom responses require the `responders` gem version to be `3.1.0` or higher, please make sure you update it if you're going to use this configuration. Check [this upgrade guide](https://github.com/heartcombo/devise/wiki/How-To:-Upgrade-to-Devise-4.9.0-[Hotwire-Turbo-integration]) for more info.
+
+_Note_: the above statuses configuration may become the default for Devise in a future release.
+
+There are a couple other changes you might need to make in your app to work with Hotwire/Turbo, if you're migrating from rails-ujs:
+
+* The `data-confirm` option that adds a confirmation modal to buttons/forms before submission needs to change to `data-turbo-confirm`, so that Turbo handles those appropriately.
+* The `data-method` option that sets the request method for link submissions needs to change to `data-turbo-method`. This is not necessary for `button_to` or `form`s since Turbo can handle those.
+
+If you're setting up Devise to sign out via `:delete`, and you're using links (instead of buttons wrapped in a form) to sign out with the `method: :delete` option, they will need to be updated as described above. (Devise does not provide sign out links/buttons in its shared views.)
+
+Make sure to inspect your views looking for those, and change appropriately.

+```ruby

+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.
