148 after completion of the response
149 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
150 is now deprecated. See --help for further information.
151 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
152 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
153 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
154 Thus accessibility of remote filesystems can be checked without any threshold comparison.

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

168 Fix check_smtp's handling of multiple-packet server responses
169 WARNING: Fix for negate which may break existing commands:
170 - stop evaluating command line options through shell twice
171 - enforce a full path for the command to run
172 The "negate" utility can now remap custom states
173 Check_radius now supports radiusclient-ng
174 The (undocumented) positional parameter parsing which check_radius used
175 instead of getopt(3) if 8 arguments were given is no longer available
176 Check_by_ssh now supports multiline output
177 IPv6 support can now be disabled using ./configure --without-ipv6
178 Fix check_ntp now honor ntp flags

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