59 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
60 check_mysql and check_radius now try clearing password in processlist just like check_mysql_query
61 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)

67 Fix linking against OpenSSL where libdl is required
69 1.4.11 13th December 2007
70 Fixed check_http regression in 1.4.10 where following redirects to
71 relative URLs on virtual hosts failed if both "-H" and "-I" were used
72 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
73 You should read the --help output so see which one is suitable for you. check_ntp_peer
74 implement stratum thresholds support (feature request #1703823).
75 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
76 as long as the thresholds range include -1. If no offset threshold is specified
77 and the offset is unavailable, will return UNKNOWN as well.
78 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
79 is "-1" as the default range starts at 0. See Examples in --help output.
80 Fixed broken usage2 in check_snmp and check_cluster
81 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
82 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
83 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c

90 1.4.10 28th September 2007
91 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
92 check_http now explicitly asks HTTP/1.1 servers to close the connection
93 after completion of the response
94 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
95 is now deprecated. See --help for further information.
96 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
97 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
98 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
99 Thus accessibility of remote filesystems can be checked without any threshold comparison.
100 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
101 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
102 New check_disk -A option to select all filesystems explicitly
103 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
104 Passing -E after -p or -r results in UNKNOWN state, now
105 This is needed due to the new ignore feature
106 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
107 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
108 to check DHCP servers on remote networks
109 New check_dhcp -m/--mac option which allows for specifying the MAC
110 address to use in the DHCP request
111 The check_dhcp -r and -s options now accept host names, too
112 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
113 Fix check_smtp's handling of multiple-packet server responses
114 WARNING: Fix for negate which may break existing commands:
115 - stop evaluating command line options through shell twice
116 - enforce a full path for the command to run
117 The "negate" utility can now remap custom states
118 Check_radius now supports radiusclient-ng
119 The (undocumented) positional parameter parsing which check_radius used
120 instead of getopt(3) if 8 arguments were given is no longer available
121 Check_by_ssh now supports multiline output
122 IPv6 support can now be disabled using ./configure --without-ipv6
123 Fix check_ntp now honor ntp flags
125 1.4.9 4th June 2006
126 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
127 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

140 check_disk extra options for regex matching of filesystems and grouping of filesystems
141 for collective thresholds
142 Better configure test for mysqlclient availability
143 Various check_ntp fixes
145 1.4.7 29th March 2007
146 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
147 Fixed MKINSTALLDIRS problem in po/
148 ./configure now detects if possible to compile check_mysql
149 Fixed broken HELO in check_smtp
150 check_icmp now allows to set a minimum number of hosts required for successs (-m)
151 check_icmp fix for *BSD when running for long time
152 check_ping times out 1 second quicker if host is unreachable
153 Root plugins installed with world executable
154 check_sybase from contrib now maintained in NagiosExchange

180 check_udp2 removed. check_udp is now linked to check_tcp.c
181 check_mailq now errors if the sub-program run returns non-zero return code. This would appear

183 Compile problems with check_snmp fixed
185 1.4.3
186 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
