Release 2.3.2
This release fixes a buffer overflow when using TSIG and algorithms
with digests larger then SHA256, reported by Mukund Sivaraman. Also
fix build dependencies for `sqrt()`.

Release 2.3.1
After a report and additional confirming results the use of `poll()` in
the network receive code for TCP and TLS has been removed. This `poll()`
initially gave better results while testing in a docker container on
it's loopback interface but when on physical networks it reduced
performance to 1/12th, so it had to go.
Thanks to Brian Wellington (Akamai/Nominum) for the initial report and
testing, and to Jan Hák (CZ.NIC) for testing and confirming the results.
Bugfix:
- Fix check for having more DNS messages in the receive buffer for TCP
and TLS

Release 2.3.0
This release adds support for DNS over TCP and TLS which can be selected
by using the mode option for `dnsperf` and `resperf`. The default server
port used is now determined by the transport mode, udp/tcp port 53 and
tls port 853.
Note that the mode option is different between the program because it was
already taken for `resperf`.
`dnsperf` changes:
- Add `-m` for setting transport mode, `udp` (default), `tcp` or `tls`
- Add verbose messages about network readiness and congestion
`resperf` changes:
- Add `-M` for setting transport mode, `udp` (default), `tcp` or `tls`
- Add `-v` for verbose mode to report about network readiness and
congestion

Release 2.2.1
The commit pulled from a fork that used `inttypes.h`, instead of ISC
internal types, missed to remove the old conversion specifier.
This was reported and fixed by Vladimír Čunát.

- Clang `scan-build` fixes
Other changes:
- add "configure --with-bind" option
- Handle bind library changes to HMAC (see #22) and other differences
between versions
- Workaround issue on FreeBSD (see #23)

Release Notes
************************
December 15, 2015
In addition to various bug fixes, the following new capabilities
were added in this release:
- The -C option was added to resperf. This option enables the local
server to act as multiple clients. By default, the local server
acts as a single client.
- the -T option was added to dnsperf. This option separates the
number of clients from the number of threads and allows more
clients to be simulated effectively. Note that using this option
impacts CPU and memory, so we recommend limiting the number of
threads.
Problems found with existing distfile for superpi:
distfiles/super_pi-20030927/super_pi.tar.gz
No changes were made to the superpi/distinfo file.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.

DNSPerf, ResPerf, and DHCPerf are free tools developed by Nominum that
make it simple to gather accurate latency and throughput metrics for
Domain Name Service (DNS) and Dynamic Host Configuration Protocol
(DHCP). These tools are easy-to-use and simulate typical Internet so
network operators can benchmark their naming and addressing
infrastructure and plan for upgrades. The latest version of the DNS
test tools (DNSPerf and ResPerf) can be used with new test files that
include IPv6 queries.
DNSPerf "self-paces" the DNS query load to simulate network
conditions. New features in DNSPerf improve the precision of latency
measurements and allow for per packet per-query latency reporting is
possible. DNSPerf is now multithreaded, multiple DNSPerf clients can
be supported in multicore systems (each client requires two
cores). The output of DNSPerf has also been improved so it is more
concise and useful. Latency data can be used to make detailed graphs
so it is simple for network operators to take advantage of the data.
