Docker Compose V2, which can be installed using the (optional) `docker-compose-plugin`
package.

### New
- Provide `.deb` and `.rpm` packages for Docker Compose V2. [Docker Compose v2.3.3](https://github.com/docker/compose/releases/tag/v2.3.3)
  can now be installed on Linux using the `docker-compose-plugin` packages, which
  provides the `docker compose` subcommand on the Docker CLI. The Docker Compose
  plugin can also be installed and run standalone to be used as a drop-in replacement
  for `docker-compose` (Docker Compose V1) [docker/docker-ce-packaging#638](https://github.com/docker/docker-ce-packaging/pull/638).
  The `compose-cli-plugin` package can also be used on older version of the Docker
  CLI with support for CLI plugins (Docker CLI 18.09 and up).
- Provide packages for the upcoming Ubuntu 22.04 "Jammy Jellyfish" LTS release [docker/docker-ce-packaging#645](https://github.com/docker/docker-ce-packaging/pull/645), [docker/containerd-packaging#271](https://github.com/docker/containerd-packaging/pull/271).

### Updates
- Updated the bundled version of buildx to [v0.8.0](https://github.com/docker/buildx/releases/tag/v0.8.0).
- Update `docker buildx` to [v0.8.0](https://github.com/docker/buildx/releases/tag/v0.8.0).
- Update `docker scan` (`docker-scan-plugin`) to [v0.17.0](https://github.com/docker/scan-cli-plugin/releases/tag/v0.17.0).
- Update containerd (`containerd.io` package) to [v1.5.10](https://github.com/containerd/containerd/releases/tag/v1.5.10).
- Update the bundled runc version to [v1.0.3](https://github.com/opencontainers/runc/releases/tag/v1.0.3).
- Update Golang runtime to Go 1.16.15.
- Updates the fluentd log driver to prevent a potential daemon crash, and prevent
  containers from hanging when using the `fluentd-async-connect=true` and the
  remote server is unreachable [moby/moby#43147](https://github.com/moby/moby/pull/43147).

### Bug fixes and enhancements
- Fix a race condition when updating the container's state [moby/moby#43166](https://github.com/moby/moby/pull/43166).
- Update the etcd dependency to prevent the daemon from incorrectly holding file locks [moby/moby#43259](https://github.com/moby/moby/pull/43259)
- Fix detection of user-namespaces when configuring the default `net.ipv4.ping_group_range` sysctl [moby/moby#43084](https://github.com/moby/moby/pull/43084).
- Retry downloading image-manifests if a connection failure happens during image
  pull [moby/moby#43333](https://github.com/moby/moby/pull/43333).
- Various fixes in command-line reference and API documentation.
- Prevent an OOM when using the "local" logging driver with containers that produce
  a large amount of log messages [moby/moby#43165](https://github.com/moby/moby/pull/43165).

## 20.10.12
2021-12-13

This release of Docker Engine contains changes in packaging only, and provides
updates to the `docker scan` and `docker buildx` commands. Versions of `docker scan`
before v0.11.0 are not able to detect the [Log4j 2 CVE-2021-44228](https://nvd.nist.gov/vuln/detail/CVE-2021-44228).
We are shipping an updated version of `docker scan` in this release to help you
scan your images for this vulnerability.

> [!NOTE]
>
> The `docker scan` command on Linux is currently only supported on x86 platforms.
> We do not yet provide a package for other hardware architectures on Linux.

The `docker scan` feature is provided as a separate package and, depending on your
upgrade or installation method, 'docker scan' may not be updated automatically to
the latest version. Use the instructions below to update `docker scan` to the latest
version. You can also use these instructions to install, or upgrade the `docker scan`
package without upgrading the Docker Engine:

On `.deb` based distributions, such as Ubuntu and Debian:

```console
$ apt-get update && apt-get install docker-scan-plugin
```

On rpm-based distributions, such as CentOS or Fedora:

```console
$ yum install docker-scan-plugin
```

After upgrading, verify you have the latest version of `docker scan` installed:
