version developed at NLANR/DAST. iperf3 is a new implementation from scratch,
with the goal of a smaller, simpler code base, and a library version of the
functionality that can be used in other programs. iperf3 also a number of
features found in other tools such as nuttcp and netperf, but were missing
from the original iperf. These include, for example, a zero-copy mode and

- update to 3.10.1:
* Fixed a problem with autoconf scripts that made builds fail in
some environments (#1154 / #1155).
* GNU autoconf 2.71 or newer is now required to regenerate iperf3's
configure scripts.
- update to 3.10:
* Fix a bug where some --reverse tests didn't terminate (#982 /
#1054).
* Responsiveness of control connections is slightly improved (#1045
/ #1046 / #1063).
* The allowable clock skew when doing authentication between client
and server is now configurable with the new --time-skew-threshold
(#1065 / #1070).
* Bitrate throttling using the -b option now works when a burst size
is specified (#1090).
* A bug with calculating CPU utilization has been fixed (#1076 /
#1077).
* A --bind-dev option to support binding sockets to a given network
interface has been added to make iperf3 work better with
multi-homed machines and/or VRFs (#817 / #1089 / #1097).
* --pidfile now works with --client mode (#1110).
* The server is now less likely to get stuck due to network errors
(#1101, #1125), controlled by the new --rcv-timeout option.
* Fixed a few bugs in termination conditions for byte or
block-limited tests (#1113, #1114, #1115).
* Added tcp_info.snd_wnd to JSON output (#1148).
* Some bugs with garbled JSON output have been fixed (#1086, #1118,
#1143 / #1146).
* Support for setting the IPv4 don't-fragment (DF) bit has been
added with the new --dont-fragment option (#1119).
* A failure with not being able to read the congestion control
algorithm under WSL1 has been fixed (#1061 / #1126).
* Error handling and error messages now make more sense in cases
where sockets were not successfully opened (#1129 / #1132 /
#1136, #1135 / #1138, #1128 / #1139).

- update to 3.9:
* A --timestamps flag has been added, which prepends a timestamp to
each output line. An optional argument to this flag, which is a
format specification to strftime(3), allows for custom timestamp
formats (#909, #1028).
* A --server-bitrate-limit flag has been added as a server-side
command-line argument. It allows a server to enforce a maximum
throughput rate; client connections that specify a higher bitrate
or exceed this bitrate during a test will be terminated. The
bitrate is expressed in bits per second, with an optional trailing
slash and integer count that specifies an averaging interval over
which to enforce the limit (#999).
* A bug that caused increased CPU usage with the --bidir option has
been fixed (#1011).
* Fixed various minor memory leaks (#1023).
