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

167 This is needed due to the new ignore feature

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

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

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