+
+  In the 4.21 update there are two major user-visible changes:
+  - the stunnel binary is in ${PREFIX}/bin/, no longer in ${PREFIX}/sbin/;
+  - the libstunnel library is in ${PREFIX}/lib/stunnel/ instead of lib/.
+
+  You may need to adjust your PATH settings or your scripts to accomodate
+  the new location of the stunnel executable (and library, if there is
+  actually anything using it).
