Release Notes: Bugs fixed: checksum calculation in the TOS target, PASV ftp with some ftpds, and multiple iptables-save/restore bugs. New features: fxp support, optimized string matching, counter-restore functions for iptables, tcp-window-tracking compatible with NAT helpers, generic sequence number offset API for NAT helpers, port scan detection matching, and lots of ported features for IPv6.
Release Notes: This release adds support for the Day Transition Ignore option in xt_time.
Release Notes: This release includes aliasing support, which translates command lines using obsolete extensions into new ones. The option parser now flags illegal negative numbers in some more extensions. A division by zero was resolved in libxt_limit as well.
Release Notes: This release adds support for changes found in Linux 3.5: the "hashlimit" match has gained support for byte-based operation, and the "recent" match has gained the "--mask" option to group hosts.
Release Notes: This release supports the new cttimeout infrastructure. This allows you to attach specific timeout policies to flow via iptables CT targets.
Release Notes: This release added support for xt_addrtype rev 1, xt_nfacct, xt_rpfilter, IPv6-capable xt_ecn, and xt_recent's reap feature.
