Release 4.2.1

Otherwise we'd be mistakenly displaying the original email in the
message (which is the same we're sending the message to).

Also tweak the messaging a bit in this case, to show that the email "is
being changed" (the change hasn't taken effect yet).

Related to #4455.

-### 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/plataformatec/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/plataformatec/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 [opensource@plataformatec.com.br](mailto:opensource@plataformatec.com.br)
+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/plataformatec/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 feeback 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!

If you add an option, be sure to inspect the migration file (created by the generator if your ORM supports them) and uncomment the appropriate section.

-There are two things that are important to keep in mind:
+If you are testing Devise internal controllers or a controller that inherits
+from Devise's, you need to tell Devise which mapping should be used before a

+but since controller tests do not pass through the router, it needs to be stated

+  @request.env['devise.mapping'] = Devise.mappings[:user]
 
-2. If you are testing Devise internal controllers or a controller that inherits from Devise's, you need to tell Devise which mapping should be used before a request. This is necessary because Devise gets this information from the router, but since functional tests do not pass through the router, it needs to be stated explicitly. For example, if you are testing the user scope, simply use:
+  # Use the sign_in helper to sign in a fixture `User` record.
+  sign_in users(:alice)
 
-    ```ruby
-    @request.env["devise.mapping"] = Devise.mappings[:user]
-    get :new
-    ```
+  get :new
+
+  # assert something
+end
+```
+
+### Integration tests
+
+Integration test helpers are available by including the
+`Devise::Test::IntegrationHelpers` module.
+
+```ruby
+class PostsTests < ActionDispatch::IntegrationTest
+  include Devise::Test::IntegrationHelpers
+end
+```
+
+Now you can use the following `sign_in` and `sign_out` methods in your integration
+tests:
+
+```ruby
+sign_in users(:bob)
+sign_in users(:bob), scope: :admin
+
+sign_out :user
+```
+
+RSpec users can include the `IntegrationHelpers` module on their `:feature` specs.
+
+```ruby
+RSpec.configure do |config|
+  config.include Devise::Test::IntegrationHelpers, type: :feature
+end
+```
+
+Unlike controller tests, integration tests do not need to supply the
+`devise.mapping` `env` value, as the mapping can be inferred by the routes that
+are executed in your tests.
