Some changes were made to the document as part of IESG review.  The revised document and diffs can be found here:

http://www.ietf.org/internet-drafts/draft-ietf-tls-dtls-heartbeat-04.txt

http://tools.ietf.org/rfcdiff?url2=draft-ietf-tls-dtls-heartbeat-04

One of the requested changes was to randomize to the data in the heartbeat message to attempt to head of any issues occurring from weak or flawed ciphers.   Since the change was relatively simple, the document was modified even though modern ciphers should not have a problem.  Flaws may be discovered in one of the many cipher suites in the future.  


Cheers,

Joe
