- update to 1.4.4:
* Monotonic/steady clock is enabled by default.
* Changed the default value of SRTO_RETRANSMITALGO socket option to 1. This
activates the efficient retransmission algorithm on the sender side which
optimizes the bandwidth usage by producing fewer retransmissions per lost
packet. The algorithm is available since v1.4.2. Intensive retransmission
algorithm (the former default) can be activated by setting
SRTO_RETRANSMITALGO=0.
* Improved random integer retrieval, which is mainly used for initial socket
ID and Initial Sequence Number (ISN) generation.
* Improved clock drift compensation algorithm. RTT samples are now taken into
account when estimating clock drift.
* Improved round-trip time (RTT) estimation.
On the receiver side, smoothed RTT (SRTT) is set to the first RTT
measurement obtained from the first ACK/ACKACK pair. When a subsequent RTT
measurement is made, an exponentially weighted moving average (EWMA) is used to
update smoothed RTT. Before the very first RTT sample is available, SRTT is
initialized as 100 ms or taken from the cache if one exists.
* On the sender side, in the case of unidirectional transmission, the values of
smoothed RTT and RTT variance are now extracted from ACK packets. In the case
of bidirectional transmission, an EWMA is still applied to be consistent with
the previous behavior.
* Improved 'No room to store incoming packet' warning with additional hints
to identify a possible reason.
* Added support for atomic types.
* Improved the logic of switching between main and backup links, extended the
list of member link states as well as defined events resulting in state
transition for Main/Backup mode of Connection Bonding.
* Documented Main/Backup mode of Connection Bonding. See here.
* Fixed group read-readiness update on the receiver side.
