Rails 4.1 and exception_notification-rake gem causing uninitialized constant ExceptionNotification - ruby-on-rails

Question

I've upgraded to Rails 4.1 and am trying to set up the exception_notification-rake gem to notify me by email of failed rake tasks.
In my Gemfile, I have gem 'exception_notification-rake'.
In development.rb, I have the following:
MyApp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Do not eager load code on boot.
config.eager_load = false
# Show full error reports and disable caching.
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Don't care if the mailer can't send.
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
# Specify what domain to use for mailer URLs
config.action_mailer.default_url_options = {host: "localhost:3000"}
config.action_mailer.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:domain => 'gmail.com',
:user_name => Rails.application.secrets.email['user'],
:password => Rails.application.secrets.email['pass'],
:authentication => 'login',
:enable_starttls_auto => true
}
# Print deprecation notices to the Rails logger.
config.active_support.deprecation = :log
# Raise an error on page load if there are pending migrations
config.active_record.migration_error = :page_load
# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true
config.after_initialize do
Bullet.enable = true
Bullet.alert = true
Bullet.bullet_logger = true
Bullet.console = true
# Bullet.growl = true
Bullet.rails_logger = true
Bullet.add_footer = true
end
config.middleware.use ExceptionNotification::Rack,
:ignore_if => lambda { |env, exception| !env[:rake?] },
:email => {
:sender_address => %{"notifier" myemail#gmail.com},
:exception_recipients => %w(myemail#gmail.com)
}
ExceptionNotifier::Rake.configure
end
As you can see, I'm passing in the user and password using Rails 4.1's secrets.yml file.
When I try starting up my Rails server, I get the following error:
/development.rb:52:in `
block in <top (required)>': uninitialized constant ExceptionNotification (NameError)
I'm guessing this is a bug in the exception_notification-rake gem which calls a previous version of the exception_notification, but I'm not sure. Any help with this would be appreciated!
Thanks :)
Update:
I've notified the exception_notification-rake gem developer about this. I have all the prerequisite gems and have a fairly vanilla setup so I think this might be a bug that needs to be fixed for Rails 4.1

As can be seen in this issue the current, published, version of ExceptionNotification does not work with rails 4.1
Until the new version is released, you can just use the master version. In your Gemfile include your gem as follows:
gem 'exception_notification', github: 'smartinez87/exception_notification'
The maintainer has released a rc-version, which you can use as follows
gem 'exception_notification', '4.1.0.rc1'
Once the new gem version is released, you can switch to the released version (4.1.0). This should not take too long I guess ;)
