Questions about CDN content update

Issue

• Users who are using the susbcription management on RHEL5.7/5.8/6.1/6.2/6.3 need to update the subscription-manager package on their systems.

• What repositories are newly added to CDN?

  1) Could you provide a list of repositories to be added to CDN?

  2) What are the new contents on CDN?

  3) Our understanding is that the subscription-manager package need to be
  updated only if the customer would like to obtain the newly added
  content.
  We think that customers who do not need the new content can continue
  using the older versions of the subscription-manager package.
  Is this correct?
