127 You should read the --help output so see which one is suitable for you. check_ntp_peer
128 implement stratum thresholds support (feature request #1703823).
129 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
130 as long as the thresholds range include -1. If no offset threshold is specified
131 and the offset is unavailable, will return UNKNOWN as well.
132 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
133 is "-1" as the default range starts at 0. See Examples in --help output.

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

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

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