Rails 4 Database cleaner - rspec-rails

Question

I'm trying to complete some tests for a rails 4 app and I keep encountering an issue with database_cleaner.
The issue is the database is not being cleaned and warnings keep raising:
DEPRECATION WARNING: #increment_open_transactions is deprecated and has no effect. (called from block (3 levels) in <top (required)> at /Users/davidhahn/Dev/cta-projects/user-management2/spec/spec_helper.rb:49)

The configuration I have setup in the spec helper is:
require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'
Spork.prefork do
# Loading more in this block will cause your tests to run faster. However,
# if you change any configuration or code from libraries loaded here, you'll
# need to restart spork for it take effect.
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
# require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
require 'database_cleaner'
# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
RSpec.configure do |config|
# ## Mock Framework
#
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#
# config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
config.mock_with :rspec
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
# config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.filter_run focus: true
config.run_all_when_everything_filtered = true
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, remove the following line or assign false
# instead of true.
# config.use_transactional_fixtures = false
config.before :each do
if Capybara.current_driver == :rack_test
DatabaseCleaner.strategy = :transaction
else
DatabaseCleaner.strategy = :truncation
end
DatabaseCleaner.start
end
config.after do
DatabaseCleaner.clean
end
# If true, the base class of anonymous controllers will be inferred
# automatically. This will be the default behavior in future versions of
# rspec-rails.
# config.infer_base_class_for_anonymous_controllers = false
# Run specs in random order to surface order dependencies. If you find an
# order dependency and want to debug it, you can fix the order by providing
# the seed, which is printed after each run.
# --seed 1234
config.order = "random"
end
end
And finally here is my gemfile
source 'https://rubygems.org'

Any help on this issue would be really helpful. Thank you!

It looks like this is fixed by the 1.0.0 RC1 release of database_cleaner. Try this in your Gemfile:
gem "database_cleaner", '1.0.0.RC1'
