+
+ Release 2.11.0
+
+ A couple of new features this release courtesy of Petr Špaček
+ @pspacek (ISC) and a bunch of bugfixes.
+
+ First off `dnsperf` can now do verbose statistics during each interval
+ when using `-S`, see long option `verbose-interval-stats`.
+
+ Next is a new latency histogram output using data structures (hg64)
+ created by Tony Finch @fanf2 (ISC), see long option
+ `latency-histogram`. These will also be shown during `-S` when used
+ together with `verbose-interval-stats`.
+
+ Lastly a small change to boolean long options, they no longer require
+ a value (`=yes`) to be enabled.
+
+ Bugfixes:
+ - Make sure the number of outstanding queries don't go negative,
+ happens if queries are timed out before being sent
+ - Fixed #208:
+ - `recv_one()`: Fix handling errno, only store EAGAIN if no other
+ error has been received
+ - `do_recv()`: Don't break on error as it will count it as a received
+ message
+ - Treat `EBADF` as `EAGAIN` for stateful connections, receive thread
+ might read from a closed socket if send thread is reconnecting
+ - `dnsperf`: warn if -c, -T, -q, -Q values are auto-adjusted
+ - Fixed #222: don't process unexpected message if the message is
+ suppressed
+
+ 14db835 Opt arg
+ fb81481 Suppress unexpected
+ 64b8c6d stats_t initialization
+ 8290775 Fix first call to diff_stats
+ 4f8bd24 Compile support histograms
+ a9b4f04 External code, latency histograms
+ d1f4b65 add detailed latency histograms
+ 044e3a2 data structures for detailed latency histograms
+ ad3fb03 Opt, verbose statistics
+ 38bc936 Command usage warnings
+ 9f31595 Bad file descriptor
+ d3650eb Receive socket error handling
+ 84c8e72 Negative outstanding
+ e7df5e1 Clarify meaning of dnsperf -S output in the man page
+ 830eb43 verbose interval stats for dnsperf
+
