81 1.4.11 13th December 2007
82 Fixed check_http regression in 1.4.10 where following redirects to

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

105 after completion of the response
106 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
107 is now deprecated. See --help for further information.
108 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
109 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
110 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
111 Thus accessibility of remote filesystems can be checked without any threshold comparison.
112 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
113 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
114 New check_disk -A option to select all filesystems explicitly
115 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
116 Passing -E after -p or -r results in UNKNOWN state, now
117 This is needed due to the new ignore feature
118 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
119 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
120 to check DHCP servers on remote networks
121 New check_dhcp -m/--mac option which allows for specifying the MAC
122 address to use in the DHCP request

124 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
125 Fix check_smtp's handling of multiple-packet server responses
126 WARNING: Fix for negate which may break existing commands:
127 - stop evaluating command line options through shell twice
128 - enforce a full path for the command to run
129 The "negate" utility can now remap custom states
130 Check_radius now supports radiusclient-ng
131 The (undocumented) positional parameter parsing which check_radius used
132 instead of getopt(3) if 8 arguments were given is no longer available
133 Check_by_ssh now supports multiline output
134 IPv6 support can now be disabled using ./configure --without-ipv6
135 Fix check_ntp now honor ntp flags
137 1.4.9 4th June 2006
138 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
139 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

161 Fixed broken HELO in check_smtp
162 check_icmp now allows to set a minimum number of hosts required for successs (-m)

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