+- update to 3.16:
+  * Multiple test streams started with -P/--parallel will now be
+    serviced by different threads. This allows iperf3 to take
+    advantage of multiple CPU cores on modern processors, and will
+    generally result in significant throughput increases
+  * OpenSSL 3 is now detected at build time. If OpenSSL 3 is found,
+    various older, deprecated, APIs will not be used. iperf3 will
+    continue to work with OpenSSL 1.1.1. OpenSSL is used as a part
+    of the iperf3 authentication functionality
+  * The authorized users file used by the authentication
+    functionality is now checked for accessibility much earlier
+    during the program startup, as opposed to being checked near
+    the start of a test (Issue #1583, PR #1585).
+  * BREAKING CHANGE: iperf3 now requires pthreads and C atomic
+    variables to compile and run.
