#### ipvlan networks ([tracking issue](https://github.com/moby/moby/issues/44925))
When upgrading to the 23.0 branch, some previously created [ipvlan](/network/ipvlan/) networks cause a panic during start:
```
panic: interface conversion: interface {} is nil, not string
goroutine 1 [running]:
github.com/docker/docker/libnetwork/drivers/ipvlan.(*configuration).UnmarshalJSON(0x40011533b0, {0x400069c2d0, 0xef, 0xef})

```
To mitigate this, affected users can downgrade and remove the network, then upgrade again.
Alternatively, the entire network store can be removed, and networks can be recreated after the upgrade. The network store is located at `/var/lib/docker/network/files/local-kv.db`. If the daemon is using an alternate `--data-root`, substitute `/var/lib/docker` for the alternate path.
#### Kata Containers ([tracking issue](https://github.com/kata-containers/kata-containers/issues/6154))
The 23.0 branch brings support for alternate containerd shims, such as `io.containerd.runsc.v1` (gVisor) and `io.containerd.kata.v2` (Kata Containers).
