iperf3/RELEASE_NOTES

== iperf 3.?.? ????-??-?? ==

* User-visible changes

  * The iperf3 project has been moved to GitHub, and various URLs in
    documentation files have been changed to point there.

  * Setting CPU affinity now works on FreeBSD.

  * iperf3 now builds on Linux systems that do not support
    TCP_CONGESTION.  Most notably this allows iperf3 to work on CentOS
    5.

  * An abort on MacOS 10.9 has been fixed (issue #135).

  * Added -I flag for the server to write a PID file, mostly useful for
    daemon mode (issue #120).

  * A bug that could break some TCP tests on FreeBSD has been fixed.

  * TCP snd_cwnd output is now printed by default on Linux (issue #99).

  * SCTP support has been added (with the --sctp flag), on Linux and
    FreeBSD (issue #131).

  * In JSON output, the --title string no longer has a colon and two
    spaces appended (issue #139).

  * A buffer for holding formatted numeric values is now
    properly-sized so that output is not truncated (issue #142).

  * A --logfile argument can now force all output to go to a file,
    rather than to a file.  This is especially useful when running an
    iperf3 server in daemon mode (issue #119).

  * Summary structures in the JSON output are now included, even if
    there is only one stream.  This change makes consuming the JSON
    output easier and more consistent (issue #151).

  * A possible buffer overflow in iperf_error.c has been fixed (issue
    #155).

* Developer-visible changes

  * Some memory leaks have been fixed.

  * A -d flag enables debugging output.

  * A .gitignore file has been added.

  * libtoolize is now invoked correctly from the bootstrap.sh script.

  * The test unit format can now be set from the API (issue #144).

  * libiperf is now built by default as both shared and static
    libraries (issue #146, issue #152).

  * Iperf API intruduced
      * Support for adding new protocols
      * Added support for callback functions
          * on_connect - executes after a connection is made to the server
          * on_new_stream - executes after a new stream is created
          * on_test_start - executes right before the test begins
          * on_test_finish - executes after the test is finished

      * Note: This feature is still in development. It is still very buggy.

== iperf 3.0b1 2010-07-08 ==

  * TCP control socket now manages messages between client and server
  * Dynamic server (gets test parameters from client)
      * Server can now set test options dynamically without having to restart.
          * Currently supported options: -l, -t, -n, -P, -R
          * Future options: -u, -b, -w, -M, -N, -I, -T, -Z, -6
