Release Notes: ngrep now builds from the same source tree for all platforms, including Win32. New drop_privs logic was introduced after problems were reported with the SPC version. An off-by-one bug which caused ngrep to exit one packet early with "-A" was fixed. A problematic cfgtest for an old broken-redhat-glibc UDP header was fixed. ngrep now sets a pcap filter "ip" by default if one is not specified. A header offset fix was made for 802.11 processing. Support for IGMP and Raw type packets was added. Support for the latest versions of libpcap, winpcap, and PCRE was added. autoconf was updated to 2.59, and config.guess and config.sub were updated to the latest versions.
Release Notes: Autoconf and the privilege revocation logic were entirely rewritten. Two new output modes were added, regex matches are now conducted in multi-line mode by default, and the abilities to specify the non-printable character, read the BPF filter logic from a file, and force the column width were also added. Program output under quiet mode was improved, and the documentation has been updated.
