152 is "-1" as the default range starts at 0. See Examples in --help output.

165 check_http now explicitly asks HTTP/1.1 servers to close the connection
166 after completion of the response
167 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
168 is now deprecated. See --help for further information.
169 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
170 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
171 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
172 Thus accessibility of remote filesystems can be checked without any threshold comparison.
173 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
174 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
175 New check_disk -A option to select all filesystems explicitly

178 This is needed due to the new ignore feature

180 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
181 to check DHCP servers on remote networks

186 Fix check_smtp's handling of multiple-packet server responses
187 WARNING: Fix for negate which may break existing commands:
188 - stop evaluating command line options through shell twice
189 - enforce a full path for the command to run
190 The "negate" utility can now remap custom states
191 Check_radius now supports radiusclient-ng
192 The (undocumented) positional parameter parsing which check_radius used
193 instead of getopt(3) if 8 arguments were given is no longer available
194 Check_by_ssh now supports multiline output
195 IPv6 support can now be disabled using ./configure --without-ipv6
196 Fix check_ntp now honor ntp flags
198 1.4.9 4th June 2007
199 Inclusion of contrib/check_cluster2 as check_cluster with some improvements

253 check_udp2 removed. check_udp is now linked to check_tcp.c
