Yes.  It is in the 1.8, 10, and trunk branches.  It was documented
in the UPGRADE.txt file:

* The Dial application d and H options do not automatically answer the call
  anymore.  It broke DTMF attended transfers.  Since many SIP and ISDN phones
  cannot send DTMF before a call is connected, you need to answer the call
  leg to those phones before using Dial with these options for them to have
  any effect before the dialed party answers.
