This file documents the major additions and syntax changes between releases.

1.4
	check_http --min changed to --pagesize, added max so min:max in check
	IPv6 support in check_ping, check_by_ssh, check_http, check_ldap, check_smtp, check_tcp
	Internationalisation support
	Performance data added (not all plugins yet)
	check_vsz and check_rss deprecated - functionality moved into check_procs
	check_swap % thresholds changed to measure amount free, instead of amount used
	check_disk syntax changes for -p, -m/-M, defaults to MB instead of kB
	check_procs -C expects no path for the command name
	New plugins - check_dhcp, check_icmp

Caveats, Notes

1 check_icmp may not build or run on all architectures. This plugin should be regarded
  as volatile (subject to change - see the CVS if in doubt). cd plugins && make check_icmp to build.

2 contrib/check_citrix has been replaced by contrib/check_ica* (requires packet_utils.pm in libexec)
