71 Fix linking against OpenSSL where libdl is required
73 1.4.11 13th December 2007
74 Fixed check_http regression in 1.4.10 where following redirects to
75 relative URLs on virtual hosts failed if both "-H" and "-I" were used
76 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
77 You should read the --help output so see which one is suitable for you. check_ntp_peer
78 implement stratum thresholds support (feature request #1703823).
79 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
80 as long as the thresholds range include -1. If no offset threshold is specified
81 and the offset is unavailable, will return UNKNOWN as well.
82 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
83 is "-1" as the default range starts at 0. See Examples in --help output.
84 Fixed broken usage2 in check_snmp and check_cluster
85 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")

96 check_http now explicitly asks HTTP/1.1 servers to close the connection
97 after completion of the response
98 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
99 is now deprecated. See --help for further information.
100 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
101 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
102 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
103 Thus accessibility of remote filesystems can be checked without any threshold comparison.
104 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
105 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
106 New check_disk -A option to select all filesystems explicitly
107 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
108 Passing -E after -p or -r results in UNKNOWN state, now
109 This is needed due to the new ignore feature
110 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
111 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
112 to check DHCP servers on remote networks
113 New check_dhcp -m/--mac option which allows for specifying the MAC
114 address to use in the DHCP request
115 The check_dhcp -r and -s options now accept host names, too
116 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
117 Fix check_smtp's handling of multiple-packet server responses
118 WARNING: Fix for negate which may break existing commands:
119 - stop evaluating command line options through shell twice
120 - enforce a full path for the command to run
121 The "negate" utility can now remap custom states
122 Check_radius now supports radiusclient-ng
123 The (undocumented) positional parameter parsing which check_radius used
124 instead of getopt(3) if 8 arguments were given is no longer available
125 Check_by_ssh now supports multiline output
126 IPv6 support can now be disabled using ./configure --without-ipv6
127 Fix check_ntp now honor ntp flags
129 1.4.9 4th June 2006
130 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
131 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

142 1.4.8 11th April 2007
143 Respects --without-world-permissions for setuid plugins
144 check_disk extra options for regex matching of filesystems and grouping of filesystems
145 for collective thresholds
146 Better configure test for mysqlclient availability

149 1.4.7 29th March 2007

151 Fixed MKINSTALLDIRS problem in po/
152 ./configure now detects if possible to compile check_mysql
153 Fixed broken HELO in check_smtp
154 check_icmp now allows to set a minimum number of hosts required for successs (-m)

156 check_ping times out 1 second quicker if host is unreachable
157 Root plugins installed with world executable

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