Docker Desktop: Further Bug Fixes and Enhancements in Shared Volumes and WSL2 Integration

- Fixed an issue that prevented users from creating files with special characters in the filenames within a shared volume. Fixes [docker/for-win#5520](https://github.com/docker/for-win/issues/5520). - Fixed handling of shared volumes with relative paths in `docker-compose.yml`. Fixes [docker/for-win#5516](https://github.com/docker/for-win/issues/5516). - Fixed handling of shared volumes where the path case (uppercase / lowercase) did not exactly match the host. Fixes [docker/for-win#5516](https://github.com/docker/for-win/issues/5516). - Fixed an issue where changing a file in the Windows file system did not update the file within the container. Fixes [docker/for-win#5530](https://github.com/docker/for-win/issues/5530) and [docker/for-win#5550](https://github.com/docker/for-win/issues/5550). - Fixed an issue that prevented users from sharing drives and sometimes incorrectly prompted users to enter file system credentials. Fixes [docker/for-win#5567](https://github.com/docker/for-win/issues/5567). - Fixed an issue which prevented users from mounting nested volumes. Fixes [docker/for-win#5540](https://github.com/docker/for-win/issues/5540). - Fixed a file synchronization issue on bind mounts. Fixes [docker/for-win#5533](https://github.com/docker/for-win/issues/5533). - Fixed an issue where timestamps were reset to zero on files within shared volumes. Fixes [docker/for-win#5528](https://github.com/docker/for-win/issues/5528) and [docker/for-win#5543](https://github.com/docker/for-win/issues/5543). - Fixed a bug which caused Docker Desktop to fail when sharing file paths longer than 260 characters. Fixes [docker/for-win#5572](https://github.com/docker/for-win/issues/5572). - Fixed an issue where some users were unable to start a container if there is a symlink in a shared volume. Fixes [docker/for-win#5582](https://github.com/docker/for-win/issues/5582). - Fixed a bug where users were unable to modify the **Manual proxy configuration** settings through the Docker Desktop UI. Fixes [docker/for-win#5606](https://github.com/docker/for-win/issues/5606) and [docker/for-win#5548](https://github.com/docker/for-win/issues/5548). - Fixed an issue where the Docker Desktop UI failed to start if the `no_proxy` environment variable has an entry that starts with a dot (.). Fixes [docker/for-win/5551](https://github.com/docker/for-win/issues/5551). - Fixed a bug that did not allow users to access the Docker Desktop UI on machines with a policy preventing access to the Windows registry. Fixes [docker/for-win#5536](https://github.com/docker/for-win/issues/5536). - Fixed an issue where disabling the WSL2 integration and re-enabling it later resulted in broken symlinks. Fixes [docker/for-win#5613](https://github.com/docker/for-win/issues/5613). - Fixed a race condition when starting the WSL engine which caused Docker Desktop to incorrectly report that the containers have exited. Fixes [docker/for-win#5607](https://github.com/docker/for-win/issues/5607). - Fixed an issue where editing code inside a container resulted in an error. Fixes [docker/for-win#5528](https://github.com/docker/for-win/issues/5528). - Fixed a bug where running the command `DockerCli.exe -SharedDrives` failed to display a list of drives that are shared. Fixes [docker/for-win#5625](https://github.com/docker/for-win/issues/5625). - Starting with Docker Desktop 2.2.0.3, you must access all shared files using their original case. For example, if you have created a file called `test`, you must open it as `test`. Attempts to open the file as `Test` will fail with the error `No such file or directory`. For more information, see _Tips on shared drives, permissions, and volume mounts_ in [File sharing](/manuals/desktop/settings-and-maintenance/settings.md#file-sharing). ### Known issues - DockerNAT has been removed from Docker Desktop 2.2.0.0 as using an IP address to communicate from the host to a container is not a supported feature. To communicate from a container to the host, you must use the special DNS name `host.docker.internal`. We also recommend using ports to communicate from the host to a container. For more information, see [Networking](/manuals/desktop/features/networking.md#use-cases-and-workarounds-for-all-platforms).

This section outlines numerous bug fixes in Docker Desktop, primarily focusing on shared volume issues. These include problems with creating files with special characters, handling relative paths and case sensitivity in `docker-compose.yml`, ensuring file updates are reflected in containers, managing drive sharing and file system credentials, mounting nested volumes, synchronizing bind mounts, preserving file timestamps, handling long file paths, resolving symlink issues, and correcting manual proxy configuration. Additionally, fixes address UI startup failures, Windows registry access, WSL2 integration with symlinks, and race conditions in the WSL engine. A change in shared file access requiring the original case is noted, along with the removal of DockerNAT and a recommendation to use `host.docker.internal` for host-to-container communication.
