["Bruce A. Mah" <>]

ESnet (Energy Sciences Network) is proud to announce the public
release of iperf-3.0.3.  This version is a maintenance release with a
few bug fixes and enhancements, notably:

* The structure of the JSON output is more consistent between the
  cases of one stream and multiple streams.

* The example programs once again build correctly.

* A possible buffer overflow related to error output has been fixed.
  (This is not believed to be exploitable.)

More information on changes can be found in the RELEASE_NOTES
file in the source distribution.

iperf3 is a tool for measuring the maximum TCP and UDP performance
along a path, allowing for the tuning of various parameters and
reporting measurements such as throughput, jitter, and datagram packet
loss.

The original iperf was implemented by NLANR / DAST.  Version 3 is a
complete reimplementation, with the goals of a smaller, simpler code
base, and a library that can be used by other programs.  It also adds
new functionality, such as CPU utilization measurements, zero copy TCP
support, and JSON output.  Note that iperf3 clients and servers are
not compatible with, and will not interoperate with, earlier versions
of iperf.

iperf3 is fully supported on Linux, FreeBSD, and MacOS X.  It may run
on other platforms as well, although it has not received the same
attention and testing.
