At this point, we have no definite plans for 149 further iperf3 releases, and ESnet will be providing a very limited 150 amount of resources for support and development, going forward. 151 However, ESnet could issue new iperf3 releases to deal with security 152 issues or high-impact bug fixes. 153 154 Requests for support, enhancements, and questions should best be 155 directed to the iperf-dev mailing list. ESnet would be open to adding 156 project members/committers from the community, in case there are 157 developers who are interested in doing more active work with iperf3 158 and/or supporting the user base. 159 160 161 2015-10-16: iperf-3.1 released 162 ............................... 163 164 | URL: http://downloads.es.net/pub/iperf/iperf-3.1.tar.gz 165 | SHA256: ``4385a32ece25cb09d4606b4c99316356b3d2cb03b318aa056b99cdb91c5ce656 iperf-3.1.tar.gz`` 166 167 This release adds support for SCTP on supported platforms, better 168 feature detection on FreeBSD, better compatibility with various 169 platforms, and a number of bug fixes. 170 171 172 2015-01-09: iperf-3.0.11 released 173 .................................. 174 175 | URL: http://downloads.es.net/pub/iperf/iperf-3.0.11.tar.gz 176 | SHA256: ``e01db5be6f47f67c987463095fe4f5b8b9ff891fb92c39104d042ad8fde97f6e iperf-3.0.11.tar.gz`` 177 178 This maintenance release adds a -1 flag to make the iperf3 execute a 179 single test and exit, needed for an upcoming bwctl release.
