Release Notes: A bug where tcpdump files would get overwritten instead of appended to has been fixed. The tcpdump magic number problem has been fixed. A sniffer mode has been added which utilises Linux mmap() packet socket and is very fast.
Release Notes: This release fixes a major crashing bug when the kernel sends oversized packets, an old race condition in the libpcap code, and a small bug in syslog output. It optimizes the code, and adds some new and nicer error messages. fwmon now also emits an error when no output mode is specified.
