Release Notes for Alpine 3.19.0

Base System

iptables-nft

The /sbin/iptables{,-save,-restore} symlinks now point to xtables-nft-multi instead of xtables-legacy-multi. This means they use the nftables kernel backend instead of the legacy iptables one.

Since the new iptables- binaries also don't use the iptables backend, to work with any existing rules and save them, you need to install iptables-legacy and use iptables-legacy-save.

Because mixing backends is not supported, you should reboot your system if you have to use the iptables commands after upgrading.

netns

The OpenRC package contains a patch to make it possible to start most services in netns namespaces. See also netns.

Others

HashiCorp packages

Due to the relicensing of HashiCorp software to BUSL-1.1 (a non-Open-Source license) (link), Vault was removed from Alpine.

Other packages (consul, nomad, packer, terraform) might be affected as well.
