99 check_ide_smart could disable offline auto tests but could not re-enable them.
100 For this reason all SMART command modes have been disabled.
101 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
102 check_dig: make sure not to give up too early when a timeout is specified with -t

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

125 were used. This is no longer the case and one must now use -n/--no-swap=<state>
126 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
127 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default

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

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

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

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

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