- Previously, when alternative packages were removed manually, it was impossible to uninstall the iptables-ipv6 packages. The underlying source code has been patched, and iptables-ipv6 can now be uninstalled regardless of manually modified alternatives.
- When upgrading the Red Hat Enterprise Linux 6.5 minimal installation to version 7.0 using the redhat-upgrade-tool utility, the "%postun" scriptlet of iptables-ipv6 failed. Blocks preventing the old package from uninstalling have been removed, and iptables-ipv6 can now be uninstalled successfully.
- With this update, IPv6 support has been added to the ipset utility, and thus the user can now manage IPSets of IPv6 addresses.
