100 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
101 check_dig: make sure not to give up too early when a timeout is specified with -t

105 Fix compilation with GnuTLS
108 New default installation prefix: /usr/local instead of /usr/local/nagios
109 check_snmp now evaluates negative values properly, which means it might return CRITICAL
110 in cases where it used to return OK. If this is undesired, the warning/critical
111 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
112 check_procs now ignores its parent process to avoid unexpected results when invoked via
114 utils.sh no longer defines ECH

147 New check_pgsql -o option to specify additional connection parameters
148 New check_fping -S option to specify the source IP address
149 New check_fping -I option to specify the interface to bind to
150 Let check_fping support IPv6
151 New check_procs -k option to ignore kernel threads (on Linux)
152 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
153 Let check_mysql support SSL
154 Let check_mysql add perfromance metrics for all checks
155 New check_mysql -f option to specify a client options file
156 New check_mysql -g option to specify a client options group
157 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
158 Let check_snmp support an arbitrary number of OIDs

168 Fix check_apt handling unknown exit codes from apt-get (Richard Leitner)
169 Fix deprecated imports of check_nmap.py (Fabio Rueda)
172 check_http behaviour of -k/--header changed since it does not seperate multiple headers by semicolons anymore. Use multiple -k switches instead.
173 check_http's --proxy_authorization option is now called --proxy-authorization (it was always documented this way)
174 The contrib directory has been removed from this distribution

355 after completion of the response
356 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
357 is now deprecated. See --help for further information.
358 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
359 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
360 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
361 Thus accessibility of remote filesystems can be checked without any threshold comparison.
362 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
363 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
364 New check_disk -A option to select all filesystems explicitly

367 This is needed due to the new ignore feature

378 - enforce a full path for the command to run
379 The "negate" utility can now remap custom states
380 Check_radius now supports radiusclient-ng
381 The (undocumented) positional parameter parsing which check_radius used
382 instead of getopt(3) if 8 arguments were given is no longer available
383 Check_by_ssh now supports multiline output
384 IPv6 support can now be disabled using ./configure --without-ipv6
385 Fix check_ntp now honor ntp flags

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