Release Notes: Corrections to SIGHUP behavior, documentation in the ipfm man page for a new signal, configuration file parsing (exit on error in config file, prints the correct line number when an error occurs), and several Debian patches.
Release Notes: A counter was added to avoid going through the logs twice. Debian support was added to the source tree. The PID file is now handled when running in daemon mode. Sending a SIGUSR1 signal to the program causes it to dump data to disk without clearing buffers. A shift/reduce conflict in the yacc grammar was removed. Miscellaneous bugs were fixed.
Release Notes: A fix for a compile problem on Red Hat-like systems, Makefile fixes, allowing only Linux to use getopt longoptions, support for net/bpf.h in old OpenBSD versions, and a fix to permit Sytem V systems to catch SIGHUP several times.
Release Notes: An Important bug with the Linux version has been fixed (it is highly recommended that you upgrade to the latest stable version), and support for accounting more than 4Gbytes has been added.
