- **WSL 2 backend:** The experimental Docker Desktop WSL 2 backend architecture introduces support for Kubernetes, provides an updated Docker daemon, offers VPN-friendly networking, and additional features. For more information, see [Docker Desktop WSL 2 backend](/manuals/desktop/features/wsl/_index.md).

- **New file sharing implementation:** Docker Desktop introduces a new file sharing implementation that replaces Samba, CIFS, and Hyper-V networking. The new implementation  offers improved I/O performance. Additionally, when using the new file system:

  - Users don't have to expose the Samba port, and therefore do not experience issues related to IT firewall or drive-sharing policy.
  - There is no need to provide user credentials to Docker Desktop. File access rights are automatically enforced when accessing mounted folders through containers.

    For more information, see the blog post [New file sharing implementation in Docker Desktop Windows](https://www.docker.com/blog/new-filesharing-implementation-in-docker-desktop-windows/).

- Added the **WSL Integration** option in **Settings** > **Resources** to select WSL 2 distributions. This option will be visible only after enabling WSL 2 on your machine.
- Introduced a new user interface for the Docker Desktop **Settings** menu.
- The Restart, Reset, and Uninstall options are now available on the **Troubleshoot** menu.
- Added the ability to start and stop existing Compose-based applications and view combined logs in the Docker Desktop **Dashboard** UI.

### Bug fixes and minor changes

- Enabled Windows features such as Hyper-V and Containers during installation, thereby reducing the need for another restart after installation.
- Added support for `Expect: 100-continue` headers in the Docker API proxy. Some HTTP clients such as `curl` send this header when the payload is large, for example, when creating containers. Fixes [moby/moby#39693](https://github.com/moby/moby/issues/39693).
- Added a loading overlay to the **Settings** and **Troubleshoot** windows to prevent editing conflicts.
- Deactivated the **Reset Kubernetes** button when Kubernetes is not activated.
- Improved the navigation in **Settings** and **Troubleshoot** UI.
- Docker Machine is no longer included in the Docker Desktop installer. You can download it separately from the [Docker Machine releases](https://github.com/docker/machine/releases) page.
- Docker Desktop now automatically restarts after an update.
- Fixed an issue where Docker Desktop auto-start was not being disabled properly on some machines.
- Fixed a container start error when a container has more than one port with an arbitrary or not-yet-configured external port number. For example, `docker run -p 80 -p 443 nginx`). Fixes [docker/for-win#4935](https://github.com/docker/for-win/issues/4935) and [docker/compose#6998](https://github.com/docker/compose/issues/6998).
- Fixed an issue which caused Docker Desktop to crash when resetting to factory defaults while running Windows containers.
- Fixed multiple issues related to Fast Startup.
- Docker Desktop now supports `inotify` events on shared filesystems.
- Docker Desktop startup is now more reliable and does not clash with host firewall software.
- Fixed a rare issue that caused to Docker Desktop to crash with the error `Unable to stop Hyper-V VM: Cannot validate argument on parameter 'SwitchName'. The argument is null or empty.`
- Fixed a bug that caused a rare crash when uninstalling Docker Desktop.
- Fixed an issue that caused Docker Desktop to fail on startup when there is an incomplete Kubernetes config file.
- Fixed various stability issues.

### Known issues

- When you start a Docker Compose application and then start a Docker App which has the same name as the Compose application, Docker Desktop displays only one application on the Dashboard. However, when you expand the application, containers that belong to both applications are displayed on the Dashboard.
- When you deploy a Docker App with multiple containers on Kubernetes, Docker Desktop displays each Pod as an application on the Dashboard.
Title: Docker Desktop Enhancements: WSL 2, File Sharing, UI Updates, and Bug Fixes
Summary
Docker Desktop introduces the experimental WSL 2 backend with Kubernetes support, an updated Docker daemon, and VPN-friendly networking. A new file sharing implementation replaces Samba/CIFS, improving I/O performance and security. UI updates include a WSL Integration option, a redesigned Settings menu, and troubleshooting options in a new Troubleshoot menu. Users can now manage Compose applications from the Dashboard. Bug fixes address Hyper-V enablement, Docker API proxy issues, Docker auto-start, container port configuration, reset errors, Fast Startup, `inotify` events, startup reliability, Hyper-V VM stopping errors, uninstall crashes, and Kubernetes config file issues. Docker Machine is no longer bundled. Known issues involve application display conflicts on the Dashboard and Pod representation in Kubernetes deployments.
