title: Rails 3 new_record? deprecated
body: <p>I have a Rails 3 app and I am planning to use the ActiveRecord method new_record? on my shared form to show the user either a Create or Update button. I looked at <a href="http://apidock.com/rails/ActiveRecord/Base/new_record%3F" rel="noreferrer">APIDock</a> and for this method and it says </p>
  
  <blockquote>
    <p>Method Deprecated: This method is
    deprecated on the latest stable
    version of Rails. The last existing
    version (v2.3.8) is shown here.</p>
  </blockquote>
  
  <p>What exactly does that mean? Does it mean that it will no longer be available moving forward?</p>
