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

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

182 This is needed due to the new ignore feature
183 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
184 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
185 to check DHCP servers on remote networks

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

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