1.4.11 13th December 2007
        Fixed check_http regression in 1.4.10 where following redirects to
          relative URLs on virtual hosts failed if both "-H" and "-I" were used
        Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
          You should read the --help output so see which one is suitable for you. check_ntp_peer
          implement stratum thresholds support (feature request #1703823).
        check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
          as long as the thresholds range include -1. If no offset threshold is specified
          and the offset is unavailable, will return UNKNOWN as well.
          NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
          is "-1" as the default range starts at 0. See Examples in --help output.

        Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
        check_http now explicitly asks HTTP/1.1 servers to close the connection
          after completion of the response
        Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
          is now deprecated. See --help for further information.
        Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
          A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
        New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
          Thus accessibility of remote filesystems can be checked without any threshold comparison.
        Check_disk's --help now prints some examples for the new features introduced in 1.4.8
        New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
        New check_disk -A option to select all filesystems explicitly
        WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
          Passing -E after -p or -r results in UNKNOWN state, now
          This is needed due to the new ignore feature
        Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
        New check_dhcp -u/--unicast option for emulating a DHCP relay in order
          to check DHCP servers on remote networks
        New check_dhcp -m/--mac option which allows for specifying the MAC
          address to use in the DHCP request
        The check_dhcp -r and -s options now accept host names, too
        Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
        Fix check_smtp's handling of multiple-packet server responses
        WARNING: Fix for negate which may break existing commands:
          - stop evaluating command line options through shell twice
          - enforce a full path for the command to run
        The "negate" utility can now remap custom states
        Check_radius now supports radiusclient-ng
        The (undocumented) positional parameter parsing which check_radius used
          instead of getopt(3) if 8 arguments were given is no longer available
