-== 3.0.0.rc
+### Unreleased
+
+### 3.2.4
+
+* enchancements
+  * `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
-  * Rails 4 and Strong Parameters compatibility. (@carlosantoniodasilva, @josevalim, @latortuga, @lucasmazza, @nashby, @rafaelfranca, @spastorino)
-  * Drop support for Rails < 3.2 and Ruby < 1.9.3.
+  * 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.

-== 2.2.4
+* 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

+
+* 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.

 ### Strong Parameters

 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 permited parameters by default are:
+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#new`) - 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`

+
+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_parameters_for`), then you will need to tell devise about those nestings and types.

+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:

+  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(roles: [], :email, :password, :password_confirmation) }

+  def sign_in
+    default_params.permit(:username, :email)

+

 ### 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 controller, for example a `Admins::SessionsController`:

-```ruby
-class Admins::SessionsController < Devise::SessionsController
-end
-```
+    ```ruby
+    class Admins::SessionsController < Devise::SessionsController
+    end
+    ```

-2) Tell the router to use this controller:
+    Note that in the above example, the controller needs to be created in the `app/controller/admins/` directory.

-```ruby
-devise_for :admins, :controllers => { :sessions => "admins/sessions" }
-```
+2. Tell the router to use this controller:

-3) And since we changed the controller, it won't use the "devise/sessions" views, so remember to copy "devise/sessions" to "admin/sessions".
+    ```ruby
+    devise_for :admins, controllers: { sessions: "admins/sessions" }
+    ```

-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 specific keys or at least remove the `:timedout` key from the hash as Devise adds this key in some circumstances, this key is not meant for display.
+3. Copy the views from `devise/sessions` to `admins/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 Admins::SessionsController < Devise::SessionsController
+      def create
+        # custom sign-in code
+      end
+    end
+    ```
+
+    Or you can simply add new behaviour to it:
+
+    ```ruby
+    class Admins::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 => "auth", :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification', :unlock => 'unblock', :registration => 'register', :sign_up => 'cmon_let_me_in' }

 ```

-    # The TokenAuthenticatable module is responsible for generating an authentication token and
-    # validating the authenticity of the same while signing in.
-    #
-    # This module only provides a few helpers to help you manage the token, but it is up to you
-    # to choose how to use it. For example, if you want to have a new token every time the user
-    # saves his account, you can do the following:
-    #
-    #   before_save :reset_authentication_token
-    #
-    # On the other hand, if you want to generate token unless one exists, you should use instead:
-    #
-    #   before_save :ensure_authentication_token

-    # If you are using token authentication with APIs and using trackable. Every

+    # ==== 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

    #
-    #      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.

    #    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

-    #      namespace :publisher do

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

+    #  * 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.

    #    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
