1.1.3:
* Fix for \{message.marker} in presence of -1.
* Switch to hexadecimal output of non-printable characters (-d).
1.1.1: 2017-Jan-20
* Release distribution fix.
1.1: 2017-Jan-19
* Support rsv1, rsv2, rsv3 reserved flags in in \{ws.* <reserved-flag>}.
* Fix statsd output for connections.opened.
* Support for \{raw Expression}, which removes ws framing.
* '-vvv' option does not dump the traffic. Use -d or --dump-* options.
* Added units (ms) to latency percentiles output.
* Add ability to specify host in -l [host:]port.
* \{message.marker} inserts a detectable timestamp to count messages/s.
1.0: 2016-Sep-29
* Export --latency-connect and --latency-first-bytes to statsd.
* --latency-percentiles now affect --statsd reporting as well.
* Added -H, --header to add HTTP headers to WebSocket handshake.
* Added --message-stop to quickly die if a given message is seen.
0.9: 2016-Aug-24
* Added -r@<Latency> form to measure message rate at a given latency.
* Websocket frame types in expressions: \{ws.ping}, \{ws.pong}, etc.
* Websocket frames accept files: \{ws.binary <image.png>}.
* Websocket frames can be non-final: \{ws.binary ...}.
* Regular expressions as data generators: \{re <regex>}.
* Display last received bytes with --verbose 2.
0.8: 2016-Jan-15
* Added --latency-connect to measure connect latency.
* Added --latency-first-byte to measure latency to first byte.
* Added --latency-percentiles to control percentile reporting.
* Mean/max latencies for messages are not reported, for UI consistency.
Use --latency-percentiles 50,100 to display.
* Added --dump-{one,all}{,-in,-out} to dump all or one connections' i/o.
* Added --write-combine=off to emit high packet rates.
0.7: 2015-Dec-11
* Added a manual page.
* Exceed 64k connections limit by using IP aliases on network interfaces.
This is a default behavior.
* --latency-marker-skip <N> to ignore the first occurrences of a marker.
* --listen-mode=active to send data for connections received through -l.
* --source-ip <IP> option to restrict or change source IPs.
* "Bandwidth per channel:" output changed to ⇅ to reflect bi-direction.
0.6: 2015-May-13
* Parse \{connection.uid} type expressions in
--first-message, --message, --latency-marker parameters,
allowing constructing payloads unique per connection.
* Added "k" multiplier to --connections;
allowing for a -c10k option (inside joke ;)
0.5: 2015-Apr-14
* --enable-asan and --enable-tsan flags to enable address/thread sanitizer.
* Do not account latencies for --first-message.
0.4.9: 2015-Apr-09
* Maximum storable latency increased from 10s to 100s.
* -e (--unescape-message-args) now affect --latency-marker string as well.
* --websocket now awaits response after sending HTTP upgrade headers.
* Add WebSocket masking on client->server communication (mandated by RFC).
* Use Boyer-Moore-Horspool to search --latency-marker in the stream.
* Add --sndbuf and --rcvbuf command line options to adjust kernel buffers
via setsockopt(SO_*BUF).
* Record latencies even if only a portion of a message has been sent.
0.4.2: 2015-Feb-23
* --channel-bandwidth limit is now applicable to sink mode (--listen-port).
* Build and run on 32-bit platforms.
0.4: 2015-Feb-03
* Initial release.
