Docker Desktop 2.4.0.0 Bug Fixes, WSL 2 Changes, and Known Issues

- Switched from `chronyd` to `sntpcd` to work around host time synchronization problems. Fixes [docker/for-win#4526](https://github.com/docker/for-win/issues/4526). - Avoid blocking startup if "Expose daemon on tcp://localhost:2375 without TLS" is set and `localhost:2375` is in use by another program. See [docker/for-win#6929](https://github.com/docker/for-win/issues/6929) [docker/for-win#6961](https://github.com/docker/for-win/issues/6961). - Fixed an issue where adding a folder on a non-existing drive in the settings would create an empty entry. See [docker/for-win#6797](https://github.com/docker/for-win/issues/6797). - Avoid failing with "Function not implemented" during file I/O on shared volumes. Fixes [docker/for-win#5955](https://github.com/docker/for-win/issues/5955) - Ensure that `docker run -v /var/run/docker.sock` rewrites Windows paths properly, see [docker/for-win#6628](https://github.com/docker/for-win/issues/6628). - Fixed a crash which occurred when Docker Desktop loads a corrupted Docker CLI configuration file. Fixes [docker/for-win#6657](https://github.com/docker/for-win/issues/6657). - Ensure `localhost` and `127.0.0.1` can both be used in the proxy settings to redirect to a proxy on the host. Fixes [docker/for-win#5715](https://github.com/docker/for-win/issues/5715) and [docker/for-win#6260](https://github.com/docker/for-win/issues/6260). - Fixed a crash when failing to login with no Internet connection. - Fixed bug in handling shared volume paths with ".." characters. Fixes [docker/for-win#5375](https://github.com/docker/for-win/issues/5375). - Report check for updates errors in toast notification. Fixes [docker/for-win#6364](https://github.com/docker/for-win/issues/6364). - Fixed an upgrade bug where users on versions still using the PowerShell based VM management can experience a silent un-installation crash leading to Docker Desktop being uninstalled instead of upgraded. - Fixed the path to the installer log file default location when the username contains a space. Fixes [docker/for-win#7941](https://github.com/docker/for-win/issues/7941). - Docker Desktop always flushes filesystem caches synchronously on container start. See [docker/for-mac#4943](https://github.com/docker/for-mac/issues/4943). - Compose-on-Kubernetes is no longer included in the Docker Desktop installer. You can download it separately from the compose-on-kubernetes [release page](https://github.com/docker/compose-on-kubernetes/releases). ### WSL 2 changes - Docker contexts are now synced between Windows and WSL distributions. - Fixed an issue that intermittently causes the backend to fail to start. - Fixed a proxy crash that happened when glibc was not compatible. See [docker/for-win#8183](https://github.com/docker/for-win/issues/8183). - Fixed an issue when removing a container mounting `/mnt/wsl` would break WSL integration. See [docker/for-win#7836](https://github.com/docker/for-win/issues/7836). - Added support for mounting files from a distribution using the Windows CLI (e.g. `docker run -v \\wsl$\Ubuntu\home\simon\web:/web ...`) - Fixed the error message when attempting to use a shared volume with a relative path. Fixes [docker/for-win#6894](https://github.com/docker/for-win/issues/6894). - Fixed an issue when updating Windows to a WSL 2 capable version, where a configuration file is locked by the old Hyper-V VM. - Fixed a discrepancy in the version of Docker Compose inside and outside of WSL 2. Fixes [docker/for-win#6461](https://github.com/docker/for-win/issues/6461). - Detect when the `docker-desktop` wsl distribution is stopped and display a clearer error message. - Fix a race condition when exposing ports. - Enable dialog no longer blocks other windows. ### Known issues - There is a known issue when using `docker-compose` with named volumes and gRPC FUSE: second and subsequent calls to `docker-compose up` will fail due to the volume path having the prefix `/host_mnt`. - There is a known issue when enabling Kubernetes where the settings UI sometimes fails to update the Kubernetes state. To work around this issue, close and re-open the Window.
