Prepare for version 4.7.1

As reported in https://github.com/plataformatec/devise/issues/5071, if
for some reason, a user in the database had the `confirmation_token`
column as a blank string, Devise would confirm that user after receiving
a request with a blank `confirmation_token` parameter.
After this commit, a request sending a blank `confirmation_token`
parameter will receive a validation error.
For applications that have users with a blank `confirmation_token` in
the database, it's recommended to manually regenerate or to nullify
them.

+    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.

+# 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 `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:
+```bash
+bin/test test/models/trackable_test.rb
+```
+
+* Running a specific test given a regex:
+```bash
+bin/test test/models/trackable_test.rb:16

+Devise 4.0 works with Rails 4.1 onwards. Add the following line to your Gemfile:

 gem 'devise'

-After you install Devise and add it to your Gemfile, you need to run the generator:
+Next, you need to run the generator:
 
 ```console
 $ rails generate devise:install
 ```
 
-The generator will install an initializer which describes ALL of Devise's configuration options. It is *imperative* that you take a look at it. When you are done, you are ready to add Devise to any of your models using the generator:
-
-```console
-$ rails generate devise MODEL
-```
-
-Replace MODEL with the class name used for the application’s users (it’s frequently `User` but could also be `Admin`). This will create a model (if one does not exist) and configure it with the default Devise modules. The generator also configures your `config/routes.rb` file to point to the Devise controller.
-
-Next, check the MODEL for any additional configuration options you might want to add, such as confirmable or lockable. 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.  For example, if you add the confirmable option in the model, you'll need to uncomment the Confirmable section in the migration. Then run `rake db:migrate`
-

 ```ruby
 config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
 ```

+
+
+In the following command you will replace `MODEL` with the class name used for the application’s users (it’s frequently `User` but could also be `Admin`). This will create a model (if one does not exist) and configure it with the default Devise modules. The generator also configures your `config/routes.rb` file to point to the Devise controller.
+
+```console
+$ rails generate devise MODEL
+```
+
+Next, check the MODEL for any additional configuration options you might want to add, such as confirmable or lockable. 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.  For example, if you add the confirmable option in the model, you'll need to uncomment the Confirmable section in the migration.
+
+Then run `rails db:migrate`

+### 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
