6.0 (not yet released) 

	* Plugins: several plugins (TODO: list) are now shipped with
	echoping and you can write your own. All new protocols will now be
	supported via plugins. Consequences:
	   - you now need an Unix with a working dlopen(3)
	   - echoping now requires the popt parsing library
	* popt: echoping now depends on popt. One main change: options
	parsing is lightly different so some scripts *may* break. A
	typical example is that "old-school" Unix aggreation of arguments
	("echoping -v4 localhost") is no longer accepted (use "echoping -v
	-4 localhost").

5.0.0 (2002-10-11)

	* Now uses getnameinfo/getaddrinfo. Two consequences:

	   - you have IPv6 support
        * With -v, now able to separate kernel (TCP) and application latency
	* Now displays the standard deviation for repeated tests. Warning:
	  this may break some scripts which parse the output of echoping.
