* Notable user-visible changes

  * BREAKING CHANGE: iperf3's authentication features, when used with
    OpenSSL prior to 3.2.0, contain a vulnerability to a side-channel
    timing attack. To address this flaw, a change has been made to the
    padding applied to encrypted strings. This change is not backwards
    compatible with older versions of iperf3 (before 3.17). To restore
    the older (vulnerable) behavior, and hence
    backwards-compatibility, use the --use-pkcs1-padding flag. The
    iperf3 team thanks Hubert Kario from RedHat for reporting this
    issue and providing feedback on the fix. (CVE-2024-26306)(PR#1695)

  * iperf3 no longer changes its current working directory in --daemon
    mode. This results in more predictable behavior with relative
    paths, in particular finding key and credential files for
    authentication. (PR#1672)

  * A new --json-stream option has been added to enable a streaming
    output format, consisting of a series of JSON objects (for the
    start of the test, each measurement interval, and the end of the
    test) separated by newlines (#444, #923, #1098).

  * UDP tests now work correctly between different endian hosts
    (#1415).

  * The --fq-rate parameter now works for --reverse tests (#1632, PR#1667).

  * The statistics reporting interval is now available in the --json
    start test object (#1663).

  * A negative time test duration is now properly flagged as an error
    (IS#1662 / PR#1666).

* Notable developer-visible changes

  * Fixes have been made to better (unofficially) support builds on
    Android (#1641 / #1651) and VxWorks (#1595).

  * iperf3 now builds correctly on architectures without native
    support for 64-bit atomic types, by linking with the libatomic
    library (#1611).
