-== trunk (2.1.0.rc2)
+### Unreleased
+
+### 3.4.1

 * enhancements
+  * Devise default views now have a similar markup to Rails scaffold views. (by @udaysinghcode, @cllns)
+  * Passing `now: true` to the `set_flash_message` helper now sets the message into
+    the `flash.now` Hash. (by @hbriggs)
+* bugfixes
+  * Fixed an regression with translation of flash messages for when the `authentication_keys`
+  config is a Hash. (by @lucasmazza)
+
+### 3.4.0
+
+* enhancements
+  * Support added for Rails 4.2. Devise now depends on the `responders` gem due
+    the extraction of the `respond_with` API from Rails. (by @lucasmazza)
+  * The Simple Form templates follow the same change from 3.3.0 by using `Log in` and adding
+    a hint about the minimum password length when `validatable` is enabled. (by @aried3r)
+  * Controller generator added as `devise:controllers SCOPE`. You can use the `-c` flag
+    to pick which controllers (`unlocks`, `confirmations`, etc) you want to generate. (by @Chun-Yang)
+  * Removed the hardcoded references for "email" in the flash messages. If you are using
+    different attributes as the `authentication_keys` they will be interpolated in the
+    messages instead. (by @timoschilling)
+* bug fix
+  * Fixed a regression where the devise generator would fail with a `ConnectionNotEstablished`
+    exception when executed inside a mountable engine. (by @lucasmazza)
+  * Ensure to return symbols in find_scope! fixing a previous regression from 3.3.0 (by @micat)
+  * Ensure all causes of failed login have the same error message (by @pjungwir)
+  * The `last_attempt_warning` now takes effect when generating the unauthenticated
+    message for your users. To keep the current behavior, this flag is now `true`
+    by default. (by @lucasmazza)
+
+### 3.3.0
+
+* enhancements
+  * Support multiple warden configuration blocks on devise configuration. (by @rossta)
+  * Previously, when a user signed out, all remember me tokens for all sessions/browsers would be
+    invalidated, and this behavior could not be changed. This behavior is now configurable via
+    `expire_all_remember_me_on_sign_out`. The default continues to be true. (by @laurocaetano)
+  * Default email messages was updated with grammar fixes, check the diff on
+    #2906 for the updated copy (by @p-originate)
+  * Allow a resource to be found based on its encrypted password token (by @karlentwistle)
+  * Adds `devise_group`, a macro to define controller helpers for multiple mappings at once. (by @dropletzz)
+  * The default views now use `Log in` instead of `Sign in` and have a hint about the minimum password length if
+    the current scope is using the `validatable` module (by @alexsoble)
+
+* bug fix
+  * Check if there is a signed in user before executing the `SessionsController#destroy`.
+  * `SessionsController#destroy` no longer yields the `resource` to receiving block,
+    since the resource isn't loaded in the action. If you need access to the current
+    resource when overring the action use the scope helper (like `current_user`) before
+    calling `super`
+  * Serialize the `last_request_at` entry as an Integer
+  * Ensure registration controller block yields happen on failure in addition to success (by @dpehrson)
+  * Only valid paths will be stored for redirections (by @parallel588)
+
+### 3.2.4
+
+* enhancements
+  * `bcrypt` dependency updated due https://github.com/codahale/bcrypt-ruby/pull/86.
+  * View generator now can generate specific views with the `-v` flag, like `rails g devise:views -v sessions` (by @kayline)
+
+### 3.2.3
+
+* enhancements
+  * Devise will use the `secret_key_base` on Rails 4+ applications as its `secret_key`.
+    You can change this and use your own secret by changing the `devise.rb` initializer.
+
+* bug fix
+  * Migrations will be properly generated when using rails 4.1.0.
+
+### 3.2.2
+
+* bug fix
+  * Ensure timeoutable works when `sign_out_all_scopes` is false (by @louman)
+  * Keep the query string when storing location (by @csexton)
+  * Require rails generator base class in devise generators
+
+### 3.2.1
+
+Security announcement: http://blog.plataformatec.com.br/2013/11/e-mail-enumeration-in-devise-in-paranoid-mode
+
+* enhancements
+  * Add `store_location_for` helper and ensure it is safe (by @matthewrudy and @homakov)
+  * Add `yield` around resource methods in Devise controllers (by @edelpero)
+
+* bug fix
+  * Bring `password_digest` back to fix compatibility with `devise-encryptable`
+  * Avoid e-mail enumeration on sign in when in paranoid mode
+
+### 3.2.0
+
+* enhancements
+  * Previously deprecated token authenticatable and insecure lookups have been removed
+  * Add a class method so you can encrypt passwords from fixtures (by @tenderlove)
+  * Send custom message when user enters invalid password and it has only one attempt
+  to enter correct password before their account will be locked (by @Lightpower)
+  * Prevent mutation of values assigned to case and whitespace santitized members (by @iamvery)
+  * Separate redirects and flash messages in `navigational_formats` and `flashing_formats` (by @ssendev)
+
+* bug fix
+  * A GET to sign_in page shouldn't extend the session (by @drewish)
+  * Splat the arguments to `strong_parameters#permit` to work around a limitation in the `strong_parameters` gem (by @memberful)
+  * Omniauth now uses `mapping.fullpath` when generating routes. This means if you call `devise_for :users` inside a scope, like `scope "/api"`, the scope will now apply to the omniauth route (by @AlexanderZaytsev)
+  * Ensure timeoutable hook respects `Devise.sign_out_all_scopes` configuration
+
+* deprecations
+  * `expire_session_data_after_sign_in!` has been deprecated in favor of `expire_data_after_sign_in!`
+
+### 3.1.1
+
+* bug fix
+  * Improve default message which asked users to sign in even when they were already signed (by @gregates)
+  * Improve error message for when the config.secret_key is missing
+
+### 3.1.0
+
+Security announcement: http://blog.plataformatec.com.br/2013/08/devise-3-1-now-with-more-secure-defaults/
+
+* backwards incompatible changes
+  * Do not store confirmation, unlock and reset password tokens directly in the database. This means tokens previously stored in the database are no longer valid. You can reenable this temporarily by setting `config.allow_insecure_token_lookup = true` in your configuration file. It is recommended to keep this configuration set to true just temporarily in your production servers only to aid migration
+  * The Devise mailer and its views were changed to explicitly receive a token argument as `@token`. You will need to update your mailers and re-copy the views to your application with `rails g devise:views`
+  * Sanitization of parameters should be done by calling `devise_parameter_sanitizer.sanitize(:action)` instead of `devise_parameter_sanitizer.for(:action)`
+
+* deprecations
+  * Token authentication is deprecated
+
+* enhancements
+  * Better security defaults
+  * Allow easier customization of parameter sanitizer (by @alexpeattie)
+
+* bug fix
+  * Do not confirm e-mail after password reset (by @moll)
+  * Do not sign in after confirmation
+  * Do not store confirmation, unlock and reset password tokens directly in the database
+  * Do not compare directly against confirmation, unlock and reset password tokens
+  * Skip storage for cookies on unverified requests
+
+### 3.0.2
+
+* bug fix
+  * Skip storage for cookies on unverified requests
+
+### 3.0.1
+
+Security announcement: http://blog.plataformatec.com.br/2013/08/csrf-token-fixation-attacks-in-devise/
+
+* enhancements
+  * Add after_confirmation callback
+
+* bug fix
+  * When using rails 3.2, the generator adds 'attr_accessible' to the model (by @jcoyne)
+  * Clean up CSRF token after authentication (by @homakov). Notice this change will clean up the CSRF Token after authentication (sign in, sign up, etc). So if you are using AJAX for such features, you will need to fetch a new CSRF token from the server.
+
+### 3.0.0
+
+* enhancements
+  * Rails 4 and Strong Parameters compatibility (by @carlosantoniodasilva, @josevalim, @latortuga, @lucasmazza, @nashby, @rafaelfranca, @spastorino)
+  * Drop support for Rails < 3.2 and Ruby < 1.9.3
+  * Enable to skip sending reconfirmation email when reconfirmable is on and `skip_confirmation_notification!` is invoked (by @tkhr)
+
+* bug fix
+  * Errors on unlock are now properly reflected on the first `unlock_keys`
+
+### 2.2.4
+
+* enhancements
+  * Add `destroy_with_password` to `DatabaseAuthenticatable`. Allows destroying a record when `:current_password` matches, similarly to how `update_with_password` works. (by @michiel3)
+  * Allow to override path after password resetting (by @worker8)
+  * Add `#skip_confirmation_notification!` method to `Confirmable`. Allows skipping confirmation email without auto-confirming. (by @gregates)
+  * allow_unconfirmed_access_for config from `:confirmable` module can be set to `nil` that means unconfirmed access for unlimited time. (by @nashby)
+  * Support Rails' token strategy on authentication (by @robhurring)
+  * Support explicitly setting the http authentication key via `config.http_authentication_key` (by @neo)
+
+* bug fix
+  * Do not redirect when accessing devise API via JSON. (by @sebastianwr)
+  * Generating scoped devise views now uses the correct scoped shared links partial instead of the default devise one (by @nashby)
+  * Fix inheriting mailer templates from `Devise::Mailer`
+  * Fix a bug when procs are used as default mailer in Devise (by @tomasv)
+
+* backwards incompatible changes
+  * Changes on session storage will expire all existing sessions on upgrade. For those storing the session in the DB, they can be upgraded according to this gist: https://gist.github.com/moll/6417606
+
+### 2.2.3
+
+Security announcement: http://blog.plataformatec.com.br/2013/01/security-announcement-devise-v2-2-3-v2-1-3-v2-0-5-and-v1-5-3-released/

+* bug fix
+  * Fix regression with case_insensitive_keys
+  * Fix regression when password is blank when it is invalid
+
+### 2.2.0
+
+* backwards incompatible changes
+  * `headers_for` is deprecated, customize the mailer directly instead
+  * All mailer methods now expect a second argument with delivery options
+  * Default minimum password length is now 8 (by @carlosgaldino)
+  * Support alternate sign in error message when email record does not exist (this adds a new I18n key to the locale file) (by @gabetax)
+  * DeviseController responds only to HTML requests by default (call `DeviseController.respond_to` or `ApplicationController.respond_to` to add new formats)
+  * Support Mongoid 3 onwards (by @durran)
+
+* enhancements
+  * Fix unlockable which could leak account existence on paranoid mode (by @latortuga)
+  * Confirmable now has a confirm_within option to set a period while the confirmation token is still valid (by @promisedlandt)
+  * Flash messages in controller now respects `resource_name` (by @latortuga)
+  * Separate `sign_in` and `sign_up` on RegistrationsController (by @rubynortheast)
+  * Add autofocus to default views (by @Radagaisus)
+  * Unlock user on password reset (by @marcinb)

-### Configuring multiple models
+### Strong Parameters

-Devise allows you to set up as many roles as you want. For example, you may have a User model and also want an Admin model with just authentication and timeoutable features. If so, just follow these steps:
+When you customize your own views, you may end up adding new attributes to forms. Rails 4 moved the parameter sanitization from the model to the controller, causing Devise to handle this concern at the controller as well.
+
+There are just three actions in Devise that allows any set of parameters to be passed down to the model, therefore requiring sanitization. Their names and the permitted parameters by default are:
+
+* `sign_in` (`Devise::SessionsController#create`) - Permits only the authentication keys (like `email`)
+* `sign_up` (`Devise::RegistrationsController#create`) - Permits authentication keys plus `password` and `password_confirmation`
+* `account_update` (`Devise::RegistrationsController#update`) - Permits authentication keys plus `password`, `password_confirmation` and `current_password`
+
+In case you want to permit additional parameters (the lazy way™) you can do with a simple before filter in your `ApplicationController`:

 ```ruby
-# Create a migration with the required fields
-create_table :admins do |t|
-  t.string :email
-  t.string :encrypted_password
-  t.timestamps
+class ApplicationController < ActionController::Base
+  before_action :configure_permitted_parameters, if: :devise_controller?
+
+  protected
+
+  def configure_permitted_parameters
+    devise_parameter_sanitizer.for(:sign_up) << :username
+  end
 end
-
-# Inside your Admin model
-devise :database_authenticatable, :timeoutable
-
-# Inside your routes
-devise_for :admins
-
-# Inside your protected controller
-before_filter :authenticate_admin!
-
-# Inside your controllers and views
-admin_signed_in?
-current_admin
-admin_session
 ```

-On the other hand, you can simply run the generator!
+The above works for any additional fields where the parameters are simple scalar types. If you have nested attributes (say you're using `accepts_nested_attributes_for`), then you will need to tell devise about those nestings and types. Devise allows you to completely change Devise defaults or invoke custom behaviour by passing a block:
+
+To permit simple scalar values for username and email, use this
+
+```ruby
+def configure_permitted_parameters
+  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :email) }
+end
+```
+
+If you have some checkboxes that express the roles a user may take on registration, the browser will send those selected checkboxes as an array. An array is not one of Strong Parameters permitted scalars, so we need to configure Devise thusly:
+
+```ruby
+def configure_permitted_parameters
+  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit({ roles: [] }, :email, :password, :password_confirmation) }
+end
+```
+For the list of permitted scalars, and how to declare permitted keys in nested hashes and arrays, see
+
+https://github.com/rails/strong_parameters#nested-parameters
+
+If you have multiple Devise models, you may want to set up different parameter sanitizer per model. In this case, we recommend inheriting from `Devise::ParameterSanitizer` and add your own logic:
+
+```ruby
+class User::ParameterSanitizer < Devise::ParameterSanitizer
+  def sign_in
+    default_params.permit(:username, :email)
+  end
+end
+```
+
+And then configure your controllers to use it:
+
+```ruby
+class ApplicationController < ActionController::Base
+  protected
+
+  def devise_parameter_sanitizer
+    if resource_class == User
+      User::ParameterSanitizer.new(User, :user, params)
+    else
+      super # Use the default one
+    end
+  end
+end
+```
+
+The example above overrides the permitted parameters for the user to be both `:username` and `:email`. The non-lazy way to configure parameters would be by defining the before filter above in a custom controller. We detail how to configure and customize controllers in some sections below.

+After doing so, you will be able to have views based on the role like `users/sessions/new` and `admins/sessions/new`. If no view is found within the scope, Devise will use the default view at `devise/sessions/new`. You can also use the generator to generate scoped views:

 ```

+If you want to generate only a few set of views, like the ones for the `registrable` and `confirmable` module,
+you can pass a list of modules to the generator with the `-v` flag.
+
+```console
+rails generate devise:views -v registrations confirmations
+```
+
 ### Configuring controllers

 If the customization at the views level is not enough, you can customize each controller by following these steps:

-1) Create your custom controller, for example a Admins::SessionsController:
+1. Create your custom controllers using the generator which requires a scope:

-```ruby
-class Admins::SessionsController < Devise::SessionsController
-end
-```
+    ```console
+    rails generate devise:controllers [scope]
+    ```

-2) Tell the router to use this controller:
+    If you specify `users` as the scope, controllers will be created in `app/controllers/users/`.
+    And the sessions controller will look like this:

-```ruby
-devise_for :admins, :controllers => { :sessions => "admins/sessions" }
-```
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      # GET /resource/sign_in
+      # def new
+      #   super
+      # end
+      ...
+    end
+    ```

-3) And since we changed the controller, it won't use the "devise/sessions" views, so remember to copy "devise/sessions" to "admin/sessions".
+2. Tell the router to use this controller:

-Remember that Devise uses flash messages to let users know if sign in was successful or failed. Devise expects your application to call "flash[:notice]" and "flash[:alert]" as appropriate.
+    ```ruby
+    devise_for :users, controllers: { sessions: "users/sessions" }
+    ```
+
+3. Copy the views from `devise/sessions` to `users/sessions`. Since the controller was changed, it won't use the default views located in `devise/sessions`.
+
+4. Finally, change or extend the desired controller actions.
+
+    You can completely override a controller action:
+
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      def create
+        # custom sign-in code
+      end
+    end
+    ```
+
+    Or you can simply add new behaviour to it:
+
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      def create
+        super do |resource|
+          BackgroundWorker.trigger(resource)
+        end
+      end
+    end
+    ```
+
+    This is useful for triggering background jobs or logging events during certain actions.
+
+Remember that Devise uses flash messages to let users know if sign in was successful or failed. Devise expects your application to call `flash[:notice]` and `flash[:alert]` as appropriate. Do not print the entire flash hash, print only specific keys. In some circumstances, Devise adds a `:timedout` key to the flash hash, which is not meant for display. Remove this key from the hash if you intend to print the entire hash.

 ### Configuring routes

 Devise also ships with default routes. If you need to customize them, you should probably be able to do it through the devise_for method. It accepts several options like :class_name, :path_prefix and so on, including the possibility to change path names for I18n:

 ```ruby
-devise_for :users, :path => "usuarios", :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification', :unlock => 'unblock', :registration => 'register', :sign_up => 'cmon_let_me_in' }
+devise_for :users, path: "auth", path_names: { sign_in: 'login', sign_out: 'logout', password: 'secret', confirmation: 'verification', unlock: 'unblock', registration: 'register', sign_up: 'cmon_let_me_in' }
 ```

 Be sure to check `devise_for` documentation for details.

+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 told explicitly. For example, if you are testing the user scope, simply do:

-```ruby
-RSpec.configure do |config|
-  config.include Devise::TestHelpers, :type => :controller
-end
-```
-

+Devise comes with Omniauth support out of the box to authenticate with other providers. To use it, just specify your omniauth configuration in `config/initializers/devise.rb`:

+```
+
+You can read more about Omniauth support in the wiki:

 * https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview

+### Configuring multiple models
+
+Devise allows you to set up as many Devise models as you want. If you want to have an Admin model with just authentication and timeout features, in addition to the User model above, just run:
+
+```ruby
+# Create a migration with the required fields
+create_table :admins do |t|
+  t.string :email
+  t.string :encrypted_password
+  t.timestamps
+end
+
+# Inside your Admin model
+devise :database_authenticatable, :timeoutable
+
+# Inside your routes
+devise_for :admins
+
+# Inside your protected controller
+before_filter :authenticate_admin!
+
+# Inside your controllers and views
+admin_signed_in?
+current_admin
+admin_session
+```
+
+Alternatively, you can simply run the Devise generator.
+
+Keep in mind that those models will have completely different routes. They **do not** and **cannot** share the same controller for sign in, sign out and so on. In case you want to have different roles sharing the same actions, we recommend you to use a role-based approach, by either providing a role column or using a dedicated gem for authorization.
+
+### ActiveJob Integration
+
+If you are using Rails 4.2 and ActiveJob to deliver ActionMailer messages in the
+background through a queueing backend, you can send Devise emails through your
+existing queue by overriding the `send_devise_notification` method in your model.
+
+```ruby
+def send_devise_notification(notification, *args)
+  devise_mailer.send(notification, self, *args).deliver_later
+end
+```
+
 ### Other ORMs

 Devise supports ActiveRecord (default) and Mongoid. To choose other ORM, you just need to require it in the initializer file.

-### Migrating from other solutions
-
-Devise implements encryption strategies for Clearance, Authlogic and Restful-Authentication. To make use of these strategies, you need set the desired encryptor in the encryptor initializer config option and add :encryptable to your model. You might also need to rename your encrypted password and salt columns to match Devise's fields (encrypted_password and password_salt).

+    # ==== Routes integration
+    #
+    # +devise_for+ is meant to play nicely with other routes methods. For example,
+    # by calling +devise_for+ inside a namespace, it automatically nests your devise
+    # controllers:
+    #
+    #     namespace :publisher do
+    #       devise_for :account
+    #     end
+    #
+    # The snippet above will use publisher/sessions controller instead of devise/sessions
+    # controller. You can revert this change or configure it directly by passing the :module
+    # option described below to +devise_for+.
+    #
+    # Also note that when you use a namespace it will affect all the helpers and methods
+    # for controllers and views. For example, using the above setup you'll end with
+    # following methods: current_publisher_account, authenticate_publisher_account!,
+    # publisher_account_signed_in, etc.
+    #
+    # The only aspect not affect by the router configuration is the model name. The
+    # model name can be explicitly set via the :class_name option.
    #
    # ==== Options
    #
    # You can configure your routes with some options:
    #
-    #  * :class_name => setup a different class to be looked up by devise, if it cannot be
+    #  * class_name: setup a different class to be looked up by devise, if it cannot be
    #    properly found by the route name.
    #
-    #      devise_for :users, :class_name => 'Account'
+    #      devise_for :users, class_name: 'Account'
    #
-    #  * :path => allows you to setup path name that will be used, as rails routes does.
+    #  * path: allows you to setup path name that will be used, as rails routes does.
    #    The following route configuration would setup your route as /accounts instead of /users:
    #
-    #      devise_for :users, :path => 'accounts'
+    #      devise_for :users, path: 'accounts'
    #
-    #  * :singular => setup the singular name for the given resource. This is used as the instance variable
+    #  * singular: setup the singular name for the given resource. This is used as the instance variable
    #    name in controller, as the name in routes and the scope given to warden.
    #
-    #      devise_for :users, :singular => :user
+    #      devise_for :users, singular: :user
    #
-    #  * :path_names => configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
+    #  * path_names: configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
    #    :password, :confirmation, :unlock.

+    #        registration: 'register', edit: 'edit/profile'
+    #      }

-    #  * :failure_app => a rack app which is invoked whenever there is a failure. Strings representing a given
+    #  * failure_app: a rack app which is invoked whenever there is a failure. Strings representing a given
    #    are also allowed as parameter.
    #
-    #  * :sign_out_via => the HTTP method(s) accepted for the :sign_out action (default: :get),
+    #  * sign_out_via: the HTTP method(s) accepted for the :sign_out action (default: :get),

    #
-    #      devise_for :users, :sign_out_via => [ :post, :delete ]
+    #      devise_for :users, sign_out_via: [ :post, :delete ]
    #
    #    You need to make sure that your sign_out controls trigger a request with a matching HTTP method.

+    #  * module: the namespace to find controllers (default: "devise", thus
    #    accessing devise/sessions, devise/registrations, and so on). If you want

-    #      end
+    #      devise_for :users, skip: :sessions

-    #    this by providing the :module option to devise_for.
+    #  * only: the opposite of :skip, tell which controllers only to generate routes to:
    #
-    #    Also pay attention that when you use a namespace it will affect all the helpers and methods for controllers
-    #    and views. For example, using the above setup you'll end with following methods:
-    #    current_publisher_account, authenticate_publisher_account!, publisher_account_signed_in, etc.
+    #      devise_for :users, only: :sessions
    #

+    #  * skip_helpers: skip generating Devise url helpers like new_session_path(@user).
    #    This is useful to avoid conflicts with previous routes and is false by default.
    #    It accepts true as option, meaning it will skip all the helpers for the controllers
    #    given in :skip but it also accepts specific helpers to be skipped:

-    #      devise_for :users, :skip => [:registrations, :confirmations], :skip_helpers => true
-    #      devise_for :users, :skip_helpers => [:registrations, :confirmations]
