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

412 certain shells

416 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have

421 permission issues when different users run the same plugin

423 were used. This is no longer the case and one must now use -n/--no-swap=<state>
424 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
425 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
427 1.5 2nd October 2013

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

653 check_http now explicitly asks HTTP/1.1 servers to close the connection
654 after completion of the response
655 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
656 is now deprecated. See --help for further information.
657 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
658 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
659 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
660 Thus accessibility of remote filesystems can be checked without any threshold comparison.
661 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
662 New check_disk -i/-I option to ignore paths/partitions based on regular expressions
663 New check_disk -A option to select all filesystems explicitly

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

674 Fix check_smtp's handling of multiple-packet server responses
675 WARNING: Fix for negate which may break existing commands:
676 - stop evaluating command line options through shell twice
677 - enforce a full path for the command to run
678 The "negate" utility can now remap custom states
679 Check_radius now supports radiusclient-ng
680 The (undocumented) positional parameter parsing which check_radius used
681 instead of getopt(3) if 8 arguments were given is no longer available
682 Check_by_ssh now supports multiline output
683 IPv6 support can now be disabled using ./configure --without-ipv6
684 Fix check_ntp now honor ntp flags

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