Docker Desktop Releases: Known Issues, New Features, Upgrades, and Bug Fixes in 4.31.0 and 4.30.0

- When upgrading to Docker Desktop 4.31.0, existing containers, images and volumes become invisible for users that created those containers and images using Docker Desktop 4.8.0 or lower, on Windows hosts with WSL only. The data is not lost, it just becomes invisible to Docker Desktop 4.31.0. If impacted, downgrade to version 4.30 or earlier. For more information see: [docker/for-win#14118](https://github.com/docker/for-win/issues/14118). #### For Linux - Ubuntu 24.04 LTS is not yet supported, Docker Desktop will fail to start. Due to a change in how the latest Ubuntu release restricts the unprivileged namespaces, `sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0` needs to be ran at least once. Refer to the [Ubuntu Blog](https://ubuntu.com/blog/). ## 4.30.0 {{< release-date date="2024-05-06" >}} {{< desktop-install all=true beta_win_arm=true version="4.30.0" build_path="/149282/" >}} ### New #### For all platforms - Docker Desktop now supports [SOCKS5 proxies](/manuals/desktop/features/networking.md#socks5-proxy-support). Requires a Business subscription. - Added a new setting to manage the onboarding survey in [Settings Management](/manuals/security/for-admins/hardened-desktop/settings-management/_index.md). #### For Windows - Added support for [Kerberos and NTLM proxy authentication](/manuals/desktop/settings-and-maintenance/settings.md#proxy-authentication) on Windows.

Fixes [docker/for-mac#7241](https://github.com/docker/for-mac/issues/7241). - Fixed a bug where high-throughput port forward transfers could stall. Fixes [docker/for-mac#7207](https://github.com/docker/for-mac/issues/7207). - Fixed CLI-plugin symlinks not being removed when CLI apps were removed. - Fixed a bug in the shared ports drawer to show the right message for local engines. - Dev Environments is being sunset and has moved to the **Beta** tab in **Features in development**. - Builds view: - Better bulk delete for build records. - Added action to open the relevant web page for container images and Git sources in build dependencies. - Added action to download Provenance and OpenTelemetry traces in Jaeger or OTLP format. - Fixed source details for remote build invocations. - Fixed a bug where multi-platform builds would show up as separate records when using a cloud builder. #### For Mac - Fixed a bug where a segmentation fault was triggered with Virtualization Framework, on post-2019 Macs. See [docker/for-mac#6824](https://github.com/docker/for-mac/issues/6824). - Enabled `CONFIG_SECURITY=y` kernel config, for example for [Tetragon](https://tetragon.io/). Fixes [docker/for-mac#7250](https://github.com/docker/for-mac/issues/7250). - Re-added support for `SQUASHFS` compression. Fixes [docker/for-mac#7260](https://github.com/docker/for-mac/issues/7260). - Fixed a bug that caused a new version of Docker Desktop to be marked as damaged. - Increased network MTU when using qemu on Apple Silicon.

This document details known issues and updates in Docker Desktop versions 4.31.0 and 4.30.0. Known issues include container/image visibility problems on Windows after upgrading to 4.31.0 and Ubuntu 24.04 LTS incompatibility. Version 4.30.0 introduces SOCKS5 proxy support, Kerberos and NTLM proxy authentication on Windows, and updates Docker Compose, Engine, Wasm runtimes, Scout CLI, Docker Debug, Linux kernel, and Go. Bug fixes address Enhanced Container Isolation, `docker events` and `docker stats` issues, self-diagnose CLI errors, port forwarding stalls, CLI-plugin symlink removal, and Builds view enhancements. Mac-specific fixes address segmentation faults, kernel configuration, SQUASHFS compression, damaged version markings, and network MTU.
