### Support for cgroup v1

**Deprecated in release: v29.0**

Support for cgroup v1 is deprecated in the v29.0 release, however, it will continue
to be supported until May 2029.
The latest release in May 2029 may not necessarily support cgroup v1,
but there will be at least one maintained branch with the support for cgroup v1.

The cgroup version currently in use can be checked by running the `docker info` command:

```console
$ docker info
<...>
Server:
<...>
Cgroup Version: 2
<...>
```

### `--pause` option on `docker commit`
