+* The ABI changes are planned for struct virtio_net in order to support vhost-user multiple queues feature. The upcoming release 2.1 will not contain these ABI changes, but release 2.2 will, and no backwards compatibility is planed due to the vhost-user multiple queues feature enabling. Binaries using this library build prior to version 2.2 will require updating and recompilation.

Applied with this rewording:
It should be integrated in release 2.2 without backward compatibility.

It *should* be in next release but we have to wait that the feature is
