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

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

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

142 Fix check_smtp's handling of multiple-packet server responses
143 WARNING: Fix for negate which may break existing commands:
144 - stop evaluating command line options through shell twice
145 - enforce a full path for the command to run
146 The "negate" utility can now remap custom states
147 Check_radius now supports radiusclient-ng
148 The (undocumented) positional parameter parsing which check_radius used
149 instead of getopt(3) if 8 arguments were given is no longer available
150 Check_by_ssh now supports multiline output
151 IPv6 support can now be disabled using ./configure --without-ipv6
152 Fix check_ntp now honor ntp flags
155 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
156 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
157 check_snmp now supports Counter64

174 1.4.7 29th March 2007
175 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
176 Fixed MKINSTALLDIRS problem in po/
177 ./configure now detects if possible to compile check_mysql
178 Fixed broken HELO in check_smtp
179 check_icmp now allows to set a minimum number of hosts required for successs (-m)

181 check_ping times out 1 second quicker if host is unreachable
182 Root plugins installed with world executable
183 check_sybase from contrib now maintained in NagiosExchange

209 check_udp2 removed. check_udp is now linked to check_tcp.c
210 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
211 as if mailqs were okay when the nagios user could not query the mail-queues
212 Compile problems with check_snmp fixed
215 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
216 SSL plugins work with gnutls as well as OpenSSL
