+- update to version 20170822
+  scamper:
+  * replace recursive versions of some functions with iterative versions.
+  * add cycle-start and cycle-stop json record implementations.
+  * fix traceroute json record: the hop transmit time value it reported
+    was junk.
+  * add support for sending json over the control socket.  use
+    "attach format json" to get this mode; "attach" by itself still
+    returns uuencoded warts.  Initial patch supplied by Young Hyun.
+  * fix possible memory leaks detected with static analysis.
+  * quality assurance on research paper cites in manual pages.
+  * spelling errors noticed by Iain R. Learmonth.
+  
+  sc_ally:
+  * add feature to dump inferred aliases from the collected data.
+  
+  sc_speedtrap:
+  * add threaded implementation of pairwise comparison to form candidate
+    alias sets, if pthreads are detected at compilation time and
+    --disable-threads configure option is not supplied.
+  
+  sc_uptime:
+  * new scamper driver to infer IPv6 device reboot windows if the device
+    returns an incrementing identifier field in the IPv6 fragmentation
+    header.  the driver is not built by default, as it expects sqlite3.
+    use --with-sc_uptime configure option to build.
