## 4.56.0

{{< desktop-install-v2 all=true win_arm_release="Early Access" version="4.56.0" build_path="//" >}}

### New

- Docker Desktop now includes Docker Compose v5 which introduces a new official Go SDK. This SDK provides a comprehensive API that lets you integrate Compose functionality directly into your applications, allowing you to load, validate, and manage multi-container environments without relying on the Compose CLI. For more information, see the [Compose SDK docs](/manuals/compose/compose-sdk.md).

### Updates

- [containerd v2.2.1](https://github.com/containerd/containerd/releases/tag/v2.2.1)
- [Docker Compose v5.0.0](https://github.com/docker/compose/releases/tag/v5.0.0)
- [cagent v1.18.6](https://github.com/docker/cagent/releases/tag/v1.18.6)

### Bug fixes and enhancements

#### For all platforms

- Fixed a panic in filesharing tests when containers don't have an IP address immediately after starting.
- Added support for custom DNS entries in the LinuxKit VM with the `ExtraDNSEntries` configuration field.

#### For Windows

- Fixed a bug on Windows where removing the state directory would fail because log files were still open.
- Fixed installations from the Microsoft Store wrongly advertizing a new update.
- Fixed a crash when running `/sbin/ldconfig` in `ubuntu:22.04` ARM64 containers by upgrading QEMU from 8.1.5 to 10.0.4. This resolves a known issue reported in [docker/for-win#15004](https://github.com/docker/for-win/issues/15004).

> [!NOTE]
>
> When running under ARM64 emulation, some `amd64` Go binaries built with older Go versions may still segfault. To avoid this, rebuild affected binaries using Go 1.25.4 or later. For details, see [golang/go#69255](https://github.com/golang/go/issues/69255) and the corresponding [Go commit](https://github.com/golang/go/commit/bf95b767394eb5643265f44c7b98bdbb85b897ce).

#### For Linux

- Fixed Kubernetes `hostPath` volume mounts failing on Linux hosts. Fixes [docker/desktop-linux#12](https://github.com/docker/desktop-linux/issues/12).
