128 as long as the thresholds range include -1. If no offset threshold is specified
129 and the offset is unavailable, will return UNKNOWN as well.

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

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

156 Passing -E after -p or -r results in UNKNOWN state, now
157 This is needed due to the new ignore feature
158 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
159 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
160 to check DHCP servers on remote networks

165 Fix check_smtp's handling of multiple-packet server responses
166 WARNING: Fix for negate which may break existing commands:
167 - stop evaluating command line options through shell twice
168 - enforce a full path for the command to run
169 The "negate" utility can now remap custom states
170 Check_radius now supports radiusclient-ng
171 The (undocumented) positional parameter parsing which check_radius used
172 instead of getopt(3) if 8 arguments were given is no longer available
173 Check_by_ssh now supports multiline output
174 IPv6 support can now be disabled using ./configure --without-ipv6
175 Fix check_ntp now honor ntp flags
177 1.4.9 4th June 2007
178 Inclusion of contrib/check_cluster2 as check_cluster with some improvements

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