314 New default installation prefix: /usr/local instead of /usr/local/nagios
315 check_snmp now evaluates negative values properly, which means it might return CRITICAL

318 check_procs now ignores its parent process to avoid unexpected results when invoked via
319 certain shells

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

377 WARNINGS
378 check_http behaviour of -k/--header changed since it does not separate multiple headers by semicolons anymore. Use multiple -k switches instead.
379 check_http's --proxy_authorization option is now called --proxy-authorization (it was always documented this way)

547 is "-1" as the default range starts at 0. See Examples in --help output.

561 after completion of the response
562 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
563 is now deprecated. See --help for further information.
564 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
565 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
566 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
567 Thus accessibility of remote filesystems can be checked without any threshold comparison.
568 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
569 New check_disk -i/-I option to ignore paths/partitions based on regular expressions
570 New check_disk -A option to select all filesystems explicitly
571 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments

575 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
576 to check DHCP servers on remote networks

583 - stop evaluating command line options through shell twice
584 - enforce a full path for the command to run
585 The "negate" utility can now remap custom states
586 Check_radius now supports radiusclient-ng
587 The (undocumented) positional parameter parsing which check_radius used
588 instead of getopt(3) if 8 arguments were given is no longer available
589 Check_by_ssh now supports multiline output
590 IPv6 support can now be disabled using ./configure --without-ipv6

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