This release has upgraded dependencies based on CVE recommendations.
Also, from this release onwards, all weave images will use the iptables-nft backend for iptables by default. Since most Linux distributions these days use that backend by default, this makes more sense than the old default. If you need to use iptables with the legacy backend instead, set the environment variable IPTABLES_BACKEND to legacy.
To do this for the Docker plugin, export the variable before using the weave script, like this:
$ export IPTABLES_BACKEND=legacy
$ weave launch
For the Kubernetes addon, set the variable for all containers defined in the manifest.
