When you run this code against Ruby 2.1.0 and previous versions you get different results:


 require 'YAML'
 yaml1 = {"key" => %Q{<%= ENV["PATH"] %>} }.to_yaml
 puts yaml1

Ruby 2.1.0 incorrectly escapes the quote


 ---
 key: "<%= ENV[\"PATH\"] %>"
  
While previous versions do not. Here is my original document for debugging this issue:
