Docker Desktop Updates: Versions 4.5.1 and 4.6.0 - Security Patches, Performance Improvements, and Bug Fixes

#### For all platforms - The Docker Desktop Dashboard Volume Management feature now offers the ability to efficiently clean up volumes using multi-select checkboxes. #### For Mac - Docker Desktop 4.6.0 gives macOS users the option of enabling a new experimental file sharing technology called VirtioFS. During testing VirtioFS has been shown to drastically reduce the time taken to sync changes between the host and VM, leading to substantial performance improvements. For more information, see [VirtioFS](/manuals/desktop/settings-and-maintenance/settings.md#beta-features). ### Updates #### For all platforms - [Docker Engine v20.10.13](/manuals/engine/release-notes/20.10.md#201013) - [Compose v2.3.3](https://github.com/docker/compose/releases/tag/v2.3.3) - [Buildx 0.8.0](https://github.com/docker/buildx/releases/tag/v0.8.0) - [containerd v1.4.13](https://github.com/containerd/containerd/releases/tag/v1.4.13) - [runc v1.0.3](https://github.com/opencontainers/runc/releases/tag/v1.0.3) - [Go 1.17.8](https://golang.org/doc/go1.17) - [Linux kernel 5.10.104](https://hub.docker.com/layers/docker/for-desktop-kernel/5.10.104-379cadd2e08e8b25f932380e9fdaab97755357b3/images/sha256-7753b60f4544e5c5eed629d12151a49c8a4b48d98b4fb30e4e65cecc20da484d?context=explore) ### Security #### For all platforms - Fixed [CVE-2022-0847](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-0847), aka “Dirty Pipe”, an issue that could enable attackers to modify files in container images on the host, from inside a container. If using the WSL 2 backend, you must update WSL 2 by running `wsl --update`. #### For Windows - Fixed [CVE-2022-26659](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-26659), which could allow an attacker to overwrite any administrator writable file on the system during the installation or the update of Docker Desktop. #### For Mac - [Qemu 6.2.0](https://wiki.qemu.org/ChangeLog/6.2) ### Bug fixes and enhancements #### For all platforms - Fixed uploading diagnostics when an HTTPS proxy is set. - Made checking for updates from the systray menu open the Software updates settings section. #### For Mac - Fixed the systray menu not displaying all menu items after starting Docker Desktop. Fixes [docker/for-mac#6192](https://github.com/docker/for-mac/issues/6192). - Fixed a regression about Docker Desktop not starting in background anymore. Fixes [docker/for-mac#6167](https://github.com/docker/for-mac/issues/6167). - Fixed missing Docker Desktop Dock icon. Fixes [docker/for-mac#6173](https://github.com/docker/for-mac/issues/6173). - Used speed up block device access when using the experimental `virtualization.framework`. See [benchmarks](https://github.com/docker/roadmap/issues/7#issuecomment-1050626886). - Increased default VM memory allocation to half of physical memory (min 2 GB, max 8 GB) for better out-of-the-box performances. #### For Windows - Fixed the UI stuck in `starting` state forever although Docker Desktop is working fine from the command line. - Fixed missing Docker Desktop systray icon [docker/for-win#12573](https://github.com/docker/for-win/issues/12573) - Fixed Registry Access Management under WSL 2 with latest 5.10.60.1 kernel. - Fixed a UI crash when selecting the containers of a Compose application started from a WSL 2 environment. Fixes [docker/for-win#12567](https://github.com/docker/for-win/issues/12567). - Fixed copying text from terminal in Quick Start Guide. Fixes [docker/for-win#12444](https://github.com/docker/for-win/issues/12444). ### Known issues #### For Mac - After enabling VirtioFS, containers with processes running with different Unix user IDs may experience caching issues. For example if a process running as `root` queries a file and another process running as user `nginx` tries to access the same file immediately, the `nginx` process will get a "Permission Denied" error. ## 4.5.1 {{< release-date date="2022-02-15" >}} ### Bug fixes and enhancements #### For Windows - Fixed an issue that caused new installations to default to the Hyper-V backend instead of WSL 2.

This document summarizes the updates for Docker Desktop versions 4.5.1 and 4.6.0. Version 4.6.0 introduces multi-select volume cleanup and experimental VirtioFS file sharing for macOS. Updates include Docker Engine v20.10.13, Compose v2.3.3, Buildx 0.8.0, containerd v1.4.13, runc v1.0.3, Go 1.17.8, and Linux kernel 5.10.104.
