10 Fix segfault in check_ntp_time and (deprecated) check_ntp (Bug #1862300)
11 check_disk should now work with large file systems (2TB+) on all archs that supports it

16 Sync to latest Gnulib (includes new floorf function)
17 check_pgsql now successfully builds with postgres lib v8.3 (Bug #1878972)
18 check_procs now accepts --ereg-argument-array for a regular expression match to the argument array
19 Reverted back to using pst3 for Solaris systems. Fixed issues re: -m64 needed to compile on 64bit systems
20 If applicable, Gettext linked dynamically instead of statically
21 check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453)
22 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help
23 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
24 check_mysql and check_radius now try clearing password in processlist just like check_mysql_query
25 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)
26 negate now has the ability to replace the status text as well (-s, --substitute)
27 Added performance data to check_ping (Christian Schneemann)
28 Added support for --extra-opts in all C plugins (disabled by default, see configure --help)
29 Fixed passive option in check_by_ssh
30 On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN.
31 Fix linking against OpenSSL where libdl is required
33 1.4.11 13th December 2007
34 Fixed check_http regression in 1.4.10 where following redirects to
35 relative URLs on virtual hosts failed if both "-H" and "-I" were used
36 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
37 You should read the --help output so see which one is suitable for you. check_ntp_peer
38 implement stratum thresholds support (feature request #1703823).
39 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
40 as long as the thresholds range include -1. If no offset threshold is specified
41 and the offset is unavailable, will return UNKNOWN as well.
42 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
43 is "-1" as the default range starts at 0. See Examples in --help output.
44 Fixed broken usage2 in check_snmp and check_cluster
45 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
46 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
47 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
48 Fixed check_load argument handling when not passing triplets (bug #1831890)
49 Fixed buffer overflow in check_snmp (CVE-2007-5623)

52 VPATH problem fixed for compiling plugins-root
54 1.4.10 28th September 2007
55 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
56 check_http now explicitly asks HTTP/1.1 servers to close the connection
57 after completion of the response
58 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
59 is now deprecated. See --help for further information.
60 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
61 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
62 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
63 Thus accessibility of remote filesystems can be checked without any threshold comparison.
64 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
65 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
66 New check_disk -A option to select all filesystems explicitly
67 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
68 Passing -E after -p or -r results in UNKNOWN state, now
69 This is needed due to the new ignore feature
70 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
71 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
72 to check DHCP servers on remote networks
73 New check_dhcp -m/--mac option which allows for specifying the MAC
74 address to use in the DHCP request
75 The check_dhcp -r and -s options now accept host names, too
76 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
77 Fix check_smtp's handling of multiple-packet server responses
78 WARNING: Fix for negate which may break existing commands:
79 - stop evaluating command line options through shell twice
80 - enforce a full path for the command to run
81 The "negate" utility can now remap custom states
82 Check_radius now supports radiusclient-ng
83 The (undocumented) positional parameter parsing which check_radius used
84 instead of getopt(3) if 8 arguments were given is no longer available
85 Check_by_ssh now supports multiline output
86 IPv6 support can now be disabled using ./configure --without-ipv6
87 Fix check_ntp now honor ntp flags
89 1.4.9 4th June 2006
90 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
91 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
92 check_snmp now supports Counter64
93 Fix compilation of check_ldap, check_radius and check_pgsql

103 Respects --without-world-permissions for setuid plugins
104 check_disk extra options for regex matching of filesystems and grouping of filesystems
105 for collective thresholds
106 Better configure test for mysqlclient availability

109 1.4.7 29th March 2007
110 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
111 Fixed MKINSTALLDIRS problem in po/
112 ./configure now detects if possible to compile check_mysql
113 Fixed broken HELO in check_smtp
114 check_icmp now allows to set a minimum number of hosts required for successs (-m)
115 check_icmp fix for *BSD when running for long time
116 check_ping times out 1 second quicker if host is unreachable
117 Root plugins installed with world executable
118 check_sybase from contrib now maintained in NagiosExchange
119 --with-nagios-user/group reinstated ./configure option

144 check_udp2 removed. check_udp is now linked to check_tcp.c
145 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
146 as if mailqs were okay when the nagios user could not query the mail-queues
147 Compile problems with check_snmp fixed
149 1.4.3
150 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
