+
+ Version 1 : original version with fixed size packets
+
+ Version 2 : both command and reply packet sizes made capable of
+ being variable length.
+
+ Version 3 : NTP_Source message lengthened (auto_offline)
+
+ Version 4 : IPv6 addressing added, 64-bit time values, sourcestats
+ and tracking reports extended, added flags to NTP source request,
+ trimmed source report, replaced fixed-point format with floating-point
+ and used also instead of integer microseconds, new commands: modify stratum,
+ modify polltarget, modify maxdelaydevratio, reselect, reselectdistance
+
+ Version 5 : auth data moved to the end of the packet to allow hashes with
+ different sizes, extended sources, tracking and activity reports, dropped
+ subnets accessed and client accesses
+
+ Version 6 : added padding to requests to prevent amplification attack,
+ changed maximum number of samples in manual list to 16, new commands: modify
+ makestep, smoothing, smoothtime
+
+ Support for authentication was removed later in version 6 of the protocol
+ and commands that required authentication are allowed only locally over Unix
+ domain socket.
+
+ Version 6 (no authentication) : changed format of client accesses by index
+ (two times), delta offset, and manual timestamp, added new fields and
+ flags to NTP source request and report, made length of manual list constant,
+ added new commands: authdata, ntpdata, onoffline, refresh, reset,
+ selectdata, serverstats, shutdown, sourcename
