134 as long as the thresholds range include -1. If no offset threshold is specified
135 and the offset is unavailable, will return UNKNOWN as well.
136 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
137 is "-1" as the default range starts at 0. See Examples in --help output.

150 check_http now explicitly asks HTTP/1.1 servers to close the connection
151 after completion of the response
152 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
153 is now deprecated. See --help for further information.
154 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
155 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
156 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
157 Thus accessibility of remote filesystems can be checked without any threshold comparison.
158 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
159 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
160 New check_disk -A option to select all filesystems explicitly
161 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
162 Passing -E after -p or -r results in UNKNOWN state, now
163 This is needed due to the new ignore feature
164 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
165 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
166 to check DHCP servers on remote networks

171 Fix check_smtp's handling of multiple-packet server responses
172 WARNING: Fix for negate which may break existing commands:
173 - stop evaluating command line options through shell twice
174 - enforce a full path for the command to run
175 The "negate" utility can now remap custom states
176 Check_radius now supports radiusclient-ng
177 The (undocumented) positional parameter parsing which check_radius used
178 instead of getopt(3) if 8 arguments were given is no longer available
179 Check_by_ssh now supports multiline output
180 IPv6 support can now be disabled using ./configure --without-ipv6
181 Fix check_ntp now honor ntp flags
183 1.4.9 4th June 2007
184 Inclusion of contrib/check_cluster2 as check_cluster with some improvements

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