 Note Regarding Synchronet for Unix
 ----------------------------------
-Synchronet for Unix does not yet support socket-based file transfer protocols,
-so SEXYZ is only currently supported on Synchronet for Unix in "stdio" mode.
+Synchronet for Unix (prior to v3.14) did not support socket-based file
+transfer protocols, so SEXYZ is only currently supported on Synchronet for
+Unix (v3.13 and older) in "stdio" mode.
+
 You can enable "stdio" mode in SEXYZ by removing '%h' (the socket descriptor)
-from the above command-lines and changing the access requirements from
-"!UNIX" to "UNIX". However, since (l)rzsz comes with most Unix distributions
-and works quite well, SEXYZ is not recommended for use on Unix BBSes for the
-time-being. See docs/sbbsunix.txt for details on configuring (l)rzsz on
-Synchronet if it's not already configured in SCFG:File Options->Transfer
-Protocols.
+from the above command-lines. If you're using Synchronet for Unix v3.14 or
+later, socket I/O mode is preferred (do not enable "stdio" mode).
