Release Notes: This release modifies the behaviour of include files, fixes a relative-path error in fgadm, and improves the file parsing test suite.
Release Notes: The example in the filter_syntax man page was fixed, as was a 64-bit compilation warning in the filter.c netmask calculation. A "-F [policy]" flush option was added, and better feedback was provided for parse errors.
Release Notes: This version fixes the iptables sub-chains (and partially fixes the same for ipchains), includes log text support, and provides an RPM spec, init script, and associated Makefile. More complete examples were included, and some small bugs were fixed.
Release Notes: A minor Makefile issue was fixed. All protocols in /etc/services and numeric protocols specified by number are now supported. The "-m" option was added to force lookup of IP addresses and port numbers.
Release Notes: A security issue in the forwarding support for iptables and ipchains (which was new in 0.7) has been fixed.
