rails--rails/actionmailer/CHANGELOG.md

Rails 4.0.0 (unreleased)

• Support Mailer.deliver_foo(*args) as a synonym for Mailer.foo(*args).deliver. This makes it easy to write e.g. Mailer.expects(:deliver_foo) when testing code that calls the mailer. Jon Leighton

• Allow delivery method options to be set per mail instance Aditya Sanghi

  If your smtp delivery settings are dynamic, you can now override settings per mail instance for e.g.

  def my_mailer(user,company)
    mail to: user.email, subject: "Welcome!",
         delivery_method_options: {user_name: company.smtp_user,
                                   password: company.smtp_password}
  end
  

  This will ensure that your default SMTP settings will be overridden by the company specific ones. You only have to override the settings that are dynamic and leave the static setting in your environment configuration file (e.g. config/environments/production.rb)

• Allow to set default Action Mailer options via config.action_mailer.default_options= Robert Pankowecki

• Raise an ActionView::MissingTemplate exception when no implicit template could be found. Damien Mathieu

• Asynchronously send messages via the Rails Queue Brian Cardarella
