+### 4.6.2 - 2019-03-26
+
+* bug fixes
+  * Revert "Set `encrypted_password` to `nil` when `password` is set to `nil`" since it broke backward compatibility with existing applications. See more on https://github.com/plataformatec/devise/issues/5033#issuecomment-476386275 (by @mracos)
+
+### 4.6.1 - 2019-02-11
+
+* bug fixes
+  * Check if `root_path` is defined with `#respond_to?` instead of `#present` (by @tegon)
+
+### 4.6.0 - 2019-02-07
+
+* enhancements
+  * Allow to skip email and password change notifications (by @iorme1)
+  * Include the use of `nil` for `allow_unconfirmed_access_for` in the docs (by @joaumg)
+  * Ignore useless files into the `.gem` file (by @huacnlee)
+  * Explain the code that prevents enumeration attacks inside `Devise::Strategies::DatabaseAuthenticatable` (by @tegon)
+  * Refactor the `devise_error_messages!` helper to render a partial (by @prograhamer)
+  * Add an option (`Devise.sign_in_after_change_password`) to not automatically sign in a user after changing a password (by @knjko)
+
+* bug fixes
+  * Fix missing comma in Simple Form generator (by @colinross)
+  * Fix error with migration generator in Rails 6 (by @oystersauce8)
+  * Set `encrypted_password` to `nil` when `password` is set to `nil` (by @sivagollapalli)

+  * Sanitize parameters inside `Devise::Models::Authenticatable#find_or_initialize_with_errors` (by @rlue)
+  * `#after_database_authentication` callback was not called after authentication on password reset (by @kanmaniselvan)

+* 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)

+  * 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.

+
+* 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)

+# 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
+## Reporting Issues
+
+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/plataformatec/devise/issues).
+
+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.
+
+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/plataformatec/devise/issues?q=i18n) regarding
+internationalization.
+
+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).
+
+**If you find a security bug, do not report it through GitHub. Please send an
 e-mail to [opensource@plataformatec.com.br](mailto:opensource@plataformatec.com.br)
-instead.
+instead.**
 
-3) If possible, replicate your issue with our
-[guides/bug_report_templates/integration_test.rb](test case example), and attach
-it to your issue or Pull Request - this way we have an isolated way to replicate
-your issue and investigate it further.
+## Sending Pull Requests
 
-4) Otherwise, please provide a fresh new Rails application that replicates your
-issue on a public GitHub repository, as some scenarios might not be possible to
-replicate using the standalone test case example.
+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.
 
-5) Do a small search on the issues tracker before submitting your issue to see
-if it was already reported / fixed. Duplicated issues will be closed to avoid
-too much noise/duplication in the issue tracker.
+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.
 
-6) When reporting an issue, include Rails, Devise and Warden versions. If you
-are getting exceptions, please include the full backtrace.
+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.
 
-7) Please do not attempt to translate Devise built in views. The views are meant
-to be a starting point and not a final version. For historical references,
-please look into closed issues/Pull regarding i18n.
+When adding new settings, you can take advantage of the [`Devise::Models.config`](https://github.com/plataformatec/devise/blob/245b1f9de0b3386b7913e14b60ea24f43b77feb0/lib/devise/models.rb#L13-L50) method to add class and instance level fallbacks
+to the new setting.
 
-8) Notice that all of your interactions in the project are expected to follow
-our [Code of Conduct](CODE_OF_CONDUCT.md)
+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.
 
-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.
+## Other ways to contribute
 
-Thanks!
+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/plataformatec/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!

-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 "rake".  For the tests to pass, you will need to have a MongoDB server (version 2.0 or newer) running on your system.
+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`:
+```
+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/plataformatec/devise/tree/master/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 on Travis 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
+```
+
+### Running tests
+Devise uses [Mini Test](https://github.com/seattlerb/minitest) as test framework.
+
+* Running all tests:
+```bash
+bin/test
+```
+
+* Running tests for an specific file:

+### Rails API Mode
+
+Rails 5+ has a built-in [API Mode](https://edgeguides.rubyonrails.org/api_app.html) which optimizes Rails for use as an API (only). One of the side effects is that it 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
