Documentation is [available here](https://github.com/containers/image/blob/master/docs/containers-registries.conf.5.md#short-name-aliasing). +- Initial support has been added for the `podman network connect` and `podman network disconnect` commands, which allow existing containers to modify what networks they are connected to. At present, these commands can only be used on running containers that did not specify `--network=none` when they were created. +- The `podman run` command now supports the `--network-alias` option to set network aliases (additional names the container can be accessed at from other containers via DNS if the `dnsname` CNI plugin is in use). Aliases can also be added and removed using the new `podman network connect` and `podman network disconnect` commands.
