70 Fix linking against OpenSSL where libdl is required
72 1.4.11 13th December 2007
73 Fixed check_http regression in 1.4.10 where following redirects to
74 relative URLs on virtual hosts failed if both "-H" and "-I" were used
75 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
76 You should read the --help output so see which one is suitable for you. check_ntp_peer
77 implement stratum thresholds support (feature request #1703823).
78 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
79 as long as the thresholds range include -1. If no offset threshold is specified
80 and the offset is unavailable, will return UNKNOWN as well.
81 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
82 is "-1" as the default range starts at 0. See Examples in --help output.
83 Fixed broken usage2 in check_snmp and check_cluster
84 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")

95 check_http now explicitly asks HTTP/1.1 servers to close the connection
96 after completion of the response
97 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
98 is now deprecated. See --help for further information.
99 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
100 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
101 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
102 Thus accessibility of remote filesystems can be checked without any threshold comparison.
103 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
104 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
105 New check_disk -A option to select all filesystems explicitly
106 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
107 Passing -E after -p or -r results in UNKNOWN state, now
108 This is needed due to the new ignore feature
109 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
110 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
111 to check DHCP servers on remote networks
112 New check_dhcp -m/--mac option which allows for specifying the MAC
113 address to use in the DHCP request
114 The check_dhcp -r and -s options now accept host names, too
115 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
116 Fix check_smtp's handling of multiple-packet server responses
117 WARNING: Fix for negate which may break existing commands:
118 - stop evaluating command line options through shell twice
119 - enforce a full path for the command to run
120 The "negate" utility can now remap custom states
121 Check_radius now supports radiusclient-ng
122 The (undocumented) positional parameter parsing which check_radius used
123 instead of getopt(3) if 8 arguments were given is no longer available
124 Check_by_ssh now supports multiline output
125 IPv6 support can now be disabled using ./configure --without-ipv6
126 Fix check_ntp now honor ntp flags
128 1.4.9 4th June 2006
129 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
130 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

144 for collective thresholds
145 Better configure test for mysqlclient availability

148 1.4.7 29th March 2007
149 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
150 Fixed MKINSTALLDIRS problem in po/
151 ./configure now detects if possible to compile check_mysql
152 Fixed broken HELO in check_smtp
153 check_icmp now allows to set a minimum number of hosts required for successs (-m)

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

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