Rails 4.1.12 (June 25, 2015)

  • Add support for inline images in mailer previews by using an interceptor class to convert cid: urls in image src attributes to data urls. The interceptor is not enabled by default but can be done in an initializer:

    # config/initializer/preview_interceptors.rb

    Andrew White

  • Fix mailer previews with attachments by using the mail gem's own API to locate the first part of the correct mime type.

    Fixes #14435.

    Andrew White

  • No changes.

Rails 4.1.10 (March 19, 2015)

  • No changes.

Rails 4.1.6 (September 11, 2014)

  • Scaffold generator _form partial adds class="field" for password confirmation fields.


  • Avoid namespacing routes inside engines.

    Mountable engines are namespaced by default so the generated routes were too while they should not.

    Fixes #14079.

    Yves Senn, Carlos Antonio da Silva, Robin Dupret

Rails 4.1.5 (August 18, 2014)

  • Check attributes passed to create_with and where.

Rails 4.1.0 (April 8, 2014)

  • Introduce Rails.gem_version as a convenience method to return, suggesting a more reliable way to perform version comparison.


    Rails.version #=> "4.1.2"
    Rails.gem_version #=> #<Gem::Version "4.1.2">
    Rails.version > "4.1.10" #=> false
    Rails.gem_version >"4.1.10") #=> true"~> 4.1.2") =~ Rails.gem_version #=> true

    Prem Sichanugrist

  • Do not crash when config/secrets.yml is empty.

    Yves Senn

    Set config.active_record.dump_schema_after_migration as false in the generated config/environments/production.rb file.

    Emil Soman

  • Added Thor-action for creation of migrations.

    Fixes #13588, #12674.

    Gert Goet

  • Ensure that bin/rails is a file before trying to execute it.

    Fixes #13825.


  • Use single quotes in generated files.

    Cristian Mircea Messel, Chulki Lee

  • The Gemfile of new applications depends on SDoc ~> 0.4.0.

    Xavier Noria

  • test_help.rb now automatically checks/maintains your test database schema. (Use config.active_record.maintain_test_schema = false to disable.)

    Jon Leighton

  • Configure secrets.yml and database.yml to read configuration from the system environment by default for production.

    José Valim

  • config.assets.raise_runtime_errors is set to true by default

    This option has been introduced in [sprockets-rails#100][] and defaults to true in new applications in development.

    Richard Schneeman

  • Generates html and text templates for mailers by default.

    Kassio Borges

  • Move secret_key_base from config/initializers/secret_token.rb to config/secrets.yml.

    secret_key_base is now saved in Rails.application.secrets.secret_key_base and it fallbacks to the value of config.secret_key_base when it is not present in config/secrets.yml.

    config/initializers/secret_token.rb is not generated by default in new applications.

    Guillermo Iguaran

  • Generate a new secrets.yml file in the config folder for new applications. By default, this file contains the application's secret_key_base, but it could also be used to store other secrets such as access keys for external APIs.

    The secrets added to this file will be accessible via Rails.application.secrets. For example, with the following secrets.yml:

      secret_key_base: 3b7cd727ee24e8444053437c36cc66c3
      some_api_key: SOMEKEY

    Rails.application.secrets.some_api_key will return SOMEKEY in the development environment.

    Guillermo Iguaran

  • Add ENV['DATABASE_URL'] support in rails dbconsole. Fixes #13320.

    Huiming Teo

  • Add Application#message_verifier method to return a message verifier.

    This verifier can be used to generate and verify signed messages in the application.

    message = Rails.application.message_verifier(:sensitive_data).generate('my sensible data')
    # => 'my sensible data'

    It is recommended not to use the same verifier for different things, so you can get different verifiers passing the name argument.

    message = Rails.application.message_verifier(:cookies).generate('my sensible cookie data')

    See the ActiveSupport::MessageVerifier documentation for more information.

    Rafael Mendonça França

  • The Spring application preloader is now installed by default for new applications. It uses the development group of the Gemfile, so will not be installed in production.

    Jon Leighton

  • Uses .railsrc while creating new plugin if it is available.

    Fixes #10700.

    Prathamesh Sonpatki

  • Remove turbolinks when generating a new application based on a template that skips it.


    Skips turbolinks adding `add_gem_entry_filter { |gem| != "turbolinks" }`
    to the template.

    Lauro Caetano

  • Instrument an load_config_initializer.railties event on each load of configuration initializer from config/initializers. Subscribers should be attached before load_config_initializers initializer completed.

    Registering subscriber examples:

    # config/application.rb
    module RailsApp
      class Application < Rails::Application
        ActiveSupport::Notifications.subscribe('load_config_initializer.railties') do |*args|
          event =*args)
          puts "Loaded initializer #{event.payload[:initializer]} (#{event.duration}ms)"
    # my_engine/lib/my_engine/engine.rb
    module MyEngine
      class Engine < ::Rails::Engine
        config.before_initialize do
          ActiveSupport::Notifications.subscribe('load_config_initializer.railties') do |*args|
            event =*args)
            puts "Loaded initializer #{event.payload[:initializer]} (#{event.duration}ms)"

    Yves Senn

  • Removal of all javascript stuff (gems and files) when generating a new application using the --skip-javascript option.

    Robin Dupret

  • Make the application name snake cased when it contains spaces

    The application name is used to fill the database.yml and session_store.rb files ; previously, if the provided name contained whitespaces, it led to unexpected names in these files.

    Robin Dupret

  • Added --model-name option to ScaffoldControllerGenerator.


  • Expose MiddlewareStack#unshift to environment configuration.

    Ben Pickles

  • rails server will only extend the logger to output to STDOUT in development environment.

    namespace :admin do
      get "dashboard/index"
