+
+    Release 2.1.0.0
+
+    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.
+
+2012-03-01
+
+    Release 2.0.0.0
+
+    In the `dnsperf` command, the following changes occurred:
+    - The socket buffer size is no longer set to 32 kilobytes by default.
+    - A new `-c clients` option was added to enable the server to act as
+      multiple clients. Each client uses the same source IP address with a
+      unique source port. Use the `clients` argument to specify the number of
+      clients represented by the server. We recommend limiting the number of
+      clients represented by the server because the `dnsperf` process uses two
+      threads for each client (one thread for sent packets and one for
+      received packets), which impacts CPU and memory.
+    - Example query files are no longer included with the `dnsperf` program.
+      Nominum provides a sample query file that is available for download at:
+      ftp://ftp.nominum.com/pub/nominum/dnsperf/data/
+    - Latency reporting improved. When the `-v` (verbose mode) option is
+      configured with the `dnsperf` command, the command output now includes
+      latency measurements and the DNS RCODE of each response. This enables
+      users to create their own latency graphs.
+    - Performance was enhanced on modern operating systems so that faster
+      name servers can be tested.
+    - The `dnsperf` command output is enhanced to display more information in a
+      compact format.
+
+    The following options were removed from the `dnsperf` command:
+    - The `-A` option for displaying command line arguments passed to the
+      `dnsperf` tool in the final statistics output. Now, the `dnsperf` command
+      output always displays command line arguments.
+    - The `-T` option for printing a histogram showing response latency after
+      completing a test run. Now, the `-v` option enables users to include
+      latency measurements in the `dnsperf` command output.
+    - The `-H` option for configuring the number of buckets for which response
+      latency is displayed. Now, the `-v` option enables users to include
+      latency measurements in the `dnsperf` command output.
+    - The `-1` option for configuring the `dnsperf` tool to run through the input
+      file exactly one time. (Now, you use the `-n 1` option to configure the
+      `dnsperf` tool to run through the input file one time.)
+    - The `-c` option for including the number of responses received (for
+      each DNS RCODE) in the final statistics output. Now, DNS RCODE responses
+      are always reported.
+
+    In the `resperf` command, the following changes occurred:
+    - The socket buffer size is no longer set to 32 kilobytes by default.
+    - The `-A` option, which displayed command line arguments passed to the
+      `resperf` tool in the final statistics output, was removed. Now, the
+      `resperf` command output always displays command line arguments.
+
+2011-12-22
+
+    Release 1.0.2.0
+
+    This release adds support for RHEL6-64 and for Solaris 10 x86-64.
+
+    Some new configuration options have been added. You can now specify:
+	- the local port from which to send requests
+	- the local address from which to send requests
+	- the maximum number of runs through the input file, up
+	  to the timeout limit.
+	- when using TSIG, algorithms other than hmac-md5 can be used.
+
+    One default has been changed:
+	- The maximum number of outstanding requests now defaults
+	  to 100.
+
+    A new example query file for IPv6, `queryfile-example-ipv6`, is now
+    included with the distribution.
+
+2008-01-10
+
+    Release 1.0.1.0
+
+    This release makes binary builds of `dnsperf` available in addition to
+    the source code version previously released.
+
+    This release of `dnsperf` includes a sample query file containing
+    100,000 queries to help with performance testing.  This query file is
+    useful for checking latencies or a continuous `dnsperf` run. In the
+    binary distribution, this file is found at:
+
+        /usr/local/nom/examples/dnsperf/queryfile-example-100thousand
+
+    In the source distribution, it is at:
+
+        ./examples/queryfile-example-100thousand
+
+    where `.` is the directory made by extracting the source tarball.
+
+    Nominum recommends using a query file with at least 3 million queries
+    for a full `resperf` run as described in the man page; we make such a
+    file available for download at:
+
+        ftp://ftp.nominum.com/pub/nominum/dnsperf/data/queryfile-example-3million.gz
+
+    The following fix is included in the source distribution:
+    - 20996: `makefile.in` does not allow overriding `mandir`
+      The `--mandir` argument to `configure`, which allows the user to
+      specify the location man pages are installed, was incorrectly
+      ignored.
+
+    `queryparse` is a contributed program available in the source
+    distribution of `dnsperf`. It can be found at `contrib/queryparse/`.
+    The following changes were made to that program:
+    - 19717: `contrib/queryparse` includes outgoing queries
+      The `queryparse` script had no way of distinguishing between incoming
+      queries and outgoing queries when applied to a traffic trace from a
+      caching server. This was addressed by adding a new flag (`-r`) that,
+      when included in the command line, will keep queries with
+      `RD=0`. Otherwise, it will default to discarding them.
+    - The ability to parse responses instead of queries was added.
+    - A check was added to avoid short packets.
+    - Logic was added to detect link type and correctly set the initial
+      offset to handle both Ethernet and Cisco HDLC frames.
+    - `queryparse` now uses `pcapy` instead of the `btk` python `libcap` module.
+
+    Note that announcements of new releases of `dnsperf` are sent to the
+    mailing list: dnsperf-announce@nominum.com.  To be added to the
+    mailing list, send a message to dnsperf-announce-request@nominum.com
+    with "subscribe" as the subject.
+
+    Known Issues:
+    - None.
+
+2006-12-21
+
+    Release 1.0.0.1
+
+    This release addresses the following issue in the `dnsperf` program:
+    - 18838/18782: `dnsperf` slow down issue
+      Because of an error in how timeout checking was being done, queries
+      were rarely timing out, so the number of valid queries in flight kept
+      dropping.  This error has been corrected.
