Docker Desktop Community Release Notes

- Docker Desktop now implements the shared volume flag `:delegated` by automatically setting up a two-way file sync with Mutagen. ## Docker Desktop Community 2.3.2.0 2020-06-25 ### Upgrades - [Docker 19.03.12](https://github.com/docker/docker-ce/releases/tag/v19.03.12) - [Docker Compose 1.26.0](https://github.com/docker/compose/releases/tag/1.26.0) - [Kubernetes 1.18.3](https://github.com/kubernetes/kubernetes/releases/tag/v1.18.3) - Beta release of the [Docker ACI integration](/engine/context/aci-integration/) ### Bug fixes and minor changes - Fixed an issue with startup when the Kubernetes certificates have expired. See [docker/for-mac#4594](https://github.com/docker/for-mac/issues/4594). - Fixed `hyperkit` on newer Macs / newer versions of `Hypervisor.framework`. - Added support for the global Mutagen config file `~/.mutagen.yml`. - Automatically set up a two-way file sync using `:delegated` option with `docker run -v` command. - Re-added device-mapper to the embedded Linux kernel. See [docker/for-mac#4549](https://github.com/docker/for-mac/issues/4549). - Improved diagnostics when using two-way synchronization with the Mutagen cache. - Switched to Mutagen `posix-raw` symlink mode which fixes cases where the symlinks point outside the synchronized directory. See [docker/for-mac#4595](https://github.com/docker/for-mac/issues/4595). - Removed the legacy Kubernetes context `docker-for-desktop`. The context `docker-desktop` should be used instead. See [docker/for-mac#4089](https://github.com/docker/for-mac/issues/4089). ## Docker Desktop Community 2.3.1.0 2020-05-20 ### New Docker Desktop introduces a directory caching mechanism to greatly improve disk performance in containers. This feature uses [mutagen.io](https://mutagen.io/) to sync files between the host and the containers and benefits from native disk performance. We appreciate you trying out an early version of the Mutagen file sync feature. Please let us know your feedback by creating an issue in the [Docker Desktop for Mac GitHub](https://github.com/docker/for-mac/issues) repository with the `Mutagen` label. ### Upgrades - [Docker Compose 1.26.0-rc4](https://github.com/docker/compose/releases/tag/1.26.0-rc4) - Upgrade to Qemu 4.2.0, add Risc-V support ### Bug fixes and minor changes - Fixed a performance regression when using shared volumes in 2.2.0.5.
