This is a bug-fix release. Problems with storing IPv6 addresses on FreeBSD have been fixed. GUI stability on operations of copying multiple objects between different data files has been improved. Parser for Cisco IOS configurations can now import configurations with wider range of constructs. Support for non-ASCII characters in the RCS commit comments has been implemented.
One of the most important changes in this release is also one of the smallest and was the simplest to fix: firewall script produced by the policy compiler for iptables used to have "executable" bit set in its permissions in versions prior to 3.0.2. However this was broken in 3.0.2, and is now fixed again.
