Rspec triggers "DEPRECATION WARNING: InstanceMethods module inside ActiveSupport :: Concern will no longer be included automatically."

I followed a tutorial at http://guides.rubyonrails.org/getting_started.html with scaffolding and added rspec. I haven't added any special code yet.

By doing...

rake spec

      

        
        
        
      

    

... I get about 20 of the following warnings:

DISCLAIMER WARNING: the InstanceMethods module inside ActiveSupport :: Concern will no longer be automatically enabled. Please define instance methods directly in RSpec :: Rails :: ViewExampleGroup. (from in / Users / pixtur / Projects / website -com / spec / views / welcome / index.html.haml_spec.rb: 3)

I don't understand what this error is trying to tell me. index.html.haml_spec.rb

was created with scaffolding and looks like this:

require 'spec_helper'

describe "welcome/index.html.haml" do
  pending "add some examples to (or delete) #{__FILE__}"
end
