Subject: [ANNOUNCE] nftables 0.8.1 release

Hi!

The Netfilter project proudly presents:

        nftables 0.8.1

This release contains mostly incremental fixes and documentation
updates, such as fixing up ./configure --with-mini-gmp for embedded
setups that don't have libgmp.

Deprecated syntax
=================

This release deprecates the "flow table" syntax in favor of "meter" to
address Netfilter's bugzilla issues:

https://bugzilla.netfilter.org/show_bug.cgi?id=1137
https://bugzilla.netfilter.org/show_bug.cgi?id=1185

This is an example of how to use it:

# nft add table filter
# nft add chain filter input { type filter hook input priority 0\; }
# nft add rule filter input meter local-traffic { ip saddr counter }

# nft list ruleset
table ip filter {
        chain input {
                type filter hook input priority 0; policy accept;
                meter local-traffic { ip saddr counter} 
        }
}
# nft list ruleset
table ip filter {
        chain input {
                type filter hook input priority 0; policy accept;
                meter local-traffic { ip saddr counter} 
        }
}
# nft list meter filter local-traffic 
table ip filter {
        meter local-traffic {
                type ipv4_addr
                elements = { 8.8.8.8 : counter packets 1 bytes 84, 84.11.121.21 : counter packets 1 bytes 76, 150.159.126.108 : counter packets 1 bytes 76, 123.102.2.4 : counter packets 1 bytes 76, 21.241.12.143 : counter packets 1 bytes 76 }
        }
}

Former 'flow table' syntax will be still around for a while, but listing
uses the new 'meter' syntax, so please revisit your scripts if you are
using this feature.
