   2.1.1 change set (as of June 23rd, 2021)
	o isochronous bug fix
	o -P and -B src port will increment for unique quintuple
	o support for port ranges, e.g. -p 6000-6008
	o double free fix per memory corruption when -l is less than 244
	o don't use pthread_join on the client --reverse, symptom hung client
	o fixes for --trip-times and small 64 byte packets
	o udp fail on reverse should exit
	o support for low duty cycle bursts (--burst-period and --burst-size)
	o final report fixes
	o full duplex ouput fixex
	o support for --incr-scrip
	o multicast setsockopt fixes
   2.1.0 change set (as of January 5th, 2021)
	o scaling improvements for -P, i.e. improved support for large numbers of traffic threads
	o major code refactoring (see doc/DESIGN_NOTES) for maintainability, extensibilty, performance, scaling, memory usage
	o support for full duplex traffic using --full-duplex
	o support for reverse traffic using --reverse
	o support for role-reversal character of asterisk in the transfer id
	o transfer id now an incrementing integer and no longer the socket id
	o support for TCP connect only tests with --connect-only
	o isochronous support compiled in by default, must use config to disable
	o support --isochronous for both UDP or TCP traffic to simulate video streams
	o support for low duty cycle traffic patterns via --burst-period and --burst-size
	o use of clock_nanosleep when supported to schedule isochronous burst starts, otherwise use nanosleep delay
	o support for --trip-times indicating the client and server clocks are synchronized to an accuracy sufficient, note: consider the use of precision time protocol as well as ask your data center to provide access to a GPS disciplined reference time source
	o support for --trip-times with -d and -r bidirectional tests
	o output TCP connect times (3WHS) in connect reports
	o support for application level tcp connect retries via --connect-retries n
	o rate-limited options of -b and --fq-rate supported for unidirectional, full duplex and reverse traffic
	o reporter thread designed to automatically cause packet reports to aggregate - mitigating and hopefully removing thread thrashing
	o support for frame or burst based reporting or sampling vs time based via -i [f|F] (experimental)
	o support for UDP traffic only from client to server with --no-udp-fin
	o support for write to read latencies (UDP and TCP) with --trip-times
	o support for sum only outputs with --sum-only
	o support for little's law calculations in --trip-time outputs
	o support for --txstart-time <epoch-time> to schedule client traffic start, timestamp support microseconds, e.g. unix $(expr $(date +%s) + 1).$(date +%N)
	o support for --txdelay-time to insert delay between TCP three way handshake (3WHS) and data transfer
	o support for --no-connect-sync which disables transmit traffic start synchronization when -P is used, defaults to synchronized
	o option of --full-duplex implementation uses a barrier on the client side to synchronize full duplex traffic
	o no limits to group sum reports, i.e. all clients will get its own sum report per a server
	o improved report timestamps, e.g. end to end or client and server based timestamps with --trip-times
	o improved settings messaging
	o improved messaging for --tcp-congestion or -Z
	o re-implemented -U for single UDP server with minimal threading interactions
	o re-implemented -1 or --singleclient where server will serialize traffic runs
	o warning message if the test were likely CPU bound instead of network i/o bound
	o fix the case when -P <value> is set on the server such that summing output is displayed
	o multicast listener will autoset -U (single server), e.g -P > 1 not supported for multicast
	o multicast listener no longer busy drops multicast packets during traffic test, i.e. only server thread receives them
	o immediate bail out on mutually exclusive command line options
	o getaddrinfo bug with -static linkage workaround and DNS lookup one time in setttings context vs twice in Settings and client traffic thread
	o fix -o or --output using freopen to redirect stdout and stderr to a file
	o support for --local-only which sets SO_DONTROUTE on a socket to limit traffic to local hosts (default is off)
	o support compile time option of --local-only to set on by default via ./configure --enable-default-localonly
	o support for date and time of in connect messages,
	  e.g. [  0] local 192.168.1.108%eth0 port 5001 connected with 192.168.1.62 port 36724 (MSS=453) (sock=5) on 2020-12-22 19:43:42 (PST)
	o support for feature of --permit-key and permit-key-timeout (defaults to 20 seconds.) The permit-key must match for the server to accpet the client's traffic. It also sets the transfer id. TCP only.
	o support for experimental feature of --near-congestion (tcp only)
	o man page updates with examples
	o tested with 1000's of traffic streams, WiFi, 10G and 100G
