Changes from RFC 3448: Incorporated changes in the RFC 3448 errata. Incorporated the larger initial windows specified in RFC 3390. Clarified how the average loss interval is calculated when the receiver has not yet seen eight loss intervals. Added more about estimating the average segment size.

Changes in draft-ietf-dccp-rfc3448bis-01.txt: Specified the receiver's initialization of the feedback timer when the first data packet doesn't have an estimate of the RTT. From feedback from Dado Colussi. Added the procedure for sending receiver feedback packets when a coarse-grained timestamp is used. From RFC 4243.

Changes to make in draft-ietf-dccp-rfc3448bis-01.txt: Specify the procedure for initializing the loss history then the first data packet sent is lost or ECN-marked. From Dado Colussi. For initializing the estimated packet drop rate when coming out of slow-start, it is ok to use the maximum receive rate so far, not just the receive rate in the last round-trip time. From Balan et al.
