FYI, iperf 2.2.1 is now released.

https://sourceforge.net/projects/iperf2/

2.2.1 (as of Nov 4th, 2024)
------------------------------
o man page updates
o support (alpha level) for --udp-l4s (linux only, requires ./configure
--enable-udp-l4s)
o buffer overflow fixes (multiple places)
o support of udp summing enhanced outputs in sum reports with -P > 1
o SETABSTIME fix
o connection report errors ouput to stderr (vs stdout)
o fixes to --connectly-only regressions
o remove --tcp-cca and --reverse restriction
o fixes to ip_tos and cmsg
o remove setsockopt for ip tos, use sendmsg and ancillary messages instead
o sample tcp_info in the middle of a -i interval
o multiple fixes for TCP_TX_DELAY
o don't autoset --tcp-write-prefetch with --trip-times, warn instead
o Add Android NDK example, add mingw64 example
o set smallest prefetch to 256K
o print wait time on server side with --tx-starttime
o fix header code #if mismatch of (HAVE_DECL_SO_TIMESTAMP) &&
(HAVE_DECL_MSG_CTRUNC) per ticket 328
o fix client side bb summing
o fix format error in timestamps
o 1) Support CSV for isochronous, both UDP and TCP 2) Reorganise CSV report
assignement to be more logical.
o support milliseconds and microseconds with iperf_formattime, also make
sure the leading zeros are printed per the field width
o fix multiple pps regressions
o csv patches per ticket 320 and 322
o add per direction byte counts with bounceback on client (server side code
yet to be done)
o fix summing init code per ticket 324
o tcp working load should use full capacity seeking behaviors
o fix csv compile breakage on MAC
o use append for --ouput vs w, ticket 321
o use --ipg units of seconds
o fix settings calculations when -b is given for --burst options
o improve port range / traffic thread count (-P) warning
o add transferid to recvmsg warning
o compute packet pps accounts for interval crossing using that timestamp vs
packet timestamp
o use object setnow() method to set lastPackeTime in first packet delay
o pps calculation needs to include partial gap value with IPGsum ahead of
PPS output
o minor fixes for DEBUG_PPS support
o fix initial udp write delay and reporting
o Rerun autoconf
o Remove unused ax_create_stdint_h
o move Socklen_t discovery entirely into dast.m4
o Remove unused DAST_REPLACE macros
o fix udp regression with high pps, sosndtimer needs to be set, don't use
write select
o Remove obsolete web100 makefile support
o fix for windows enhanced writes with summing
o don't mix typecast with format specifiers, use %ld for (long) typecast
o use typecast for time_val seconds for portability, fix windows 64 cross
compile
o Set default compiler and load flags without overiding user choice.
o Move packet and tuntap checks later so they don't execute before compiler
checks.
o Use HAVE_GETIFADDRS instead of HAVE_IFADDRS_H for Android and any other
OS that has the header file but might not enable the actual feature
o Remove code that is unused and deprecated
o Update defuns to comply with autoconf-2.72
o use netinet vs linux for ip.h and udp.h, add configure.ac checks for the
header files, update dscp.h for new defines not in netienet per WFA/WMM
inputs
o disable SO_REUSEPORT for server side
o various fixes in ReportOutputs including divide by zero test, segv fixes,
and spacings
o fix for UDP 64b seq number detection per packet header
o fix configure.ac to support Win64 compiles
o ticket 314: eliminate the udp accept race between listener and server
thread using a conditional signal
o ticket 313: remove support for configure --enable-static-bin, never
worked and only misleads
o ticket 312: regression, fix for segv in UDP summing enhance outputs
o ticket 311: histogram worst timestamp needs proper formatting, didn't
print leading zeros for the usec portion
o ticket 310: regression on client setting reports, too many with things
like -P > 1
o ticket 309 (regression): udp summing is broken. Need to reset sum event
counters after interval reports
o ticket 308: -P should be order independent
o ticket 305: add support for --skip-rx-copy w/tcp. Set recv flags to
MSG_TRUNC when the payload isn't needed by iperf
o ticket 157 (regression since 2.1.4): remove AM_CONDITIONAL for TUN & TAP.
Move the AF_PACKET AM_CONDITIONAL to its own scope. Rerun autoreconf
automake
o fix output for tos on server side
o remove settings report for client threads when P > 1
o fix timeval outputs to use %06ld for usecs
