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

140 after completion of the response
141 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
142 is now deprecated. See --help for further information.
143 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
144 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
145 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
146 Thus accessibility of remote filesystems can be checked without any threshold comparison.
147 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
148 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
149 New check_disk -A option to select all filesystems explicitly

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

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

196 Fixed broken HELO in check_smtp
197 check_icmp now allows to set a minimum number of hosts required for successs (-m)

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