+ - Prepared the checksum code for an upcoming xxHash release that provides new
+   XXH3 & XXH128 checksum routines.  These will not be compiled into rsync
+   until the xxhash v0.8.0 include files are installed on the build host, and
+   that release is a few weeks away at the time this was written.  So, if it's
+   now the future and you have packaged and installed xxhash-0.8.0-devel, a
+   fresh rebuild of rsync 3.2.2 will give you the new checksum routines.
