Fixes [docker/for-win#6037](https://github.com/docker/for-win/issues/6037). - Fixed a file descriptor leak in `vpnkit-bridge`. Fixes [docker/for-win#5841](https://github.com/docker/for-win/issues/5841). - Added a link to the Edge channel from the UI. - Made the embedded terminal resizable. - Fixed a bug where diagnostic upload would fail if the username contained spaces. - Fixed a bug where the Docker UI could be started without the engine. - Switched from `ahci-hd` to `virtio-blk` to avoid an AHCI deadlock, see [moby/hyperkit#94](https://github.com/moby/hyperkit/issues/94) and [docker/for-mac#1835](https://github.com/docker/for-mac/issues/1835). - Fixed an issue where a container port could not be exposed on a specific host IP. See [docker/for-mac#4209](https://github.com/docker/for-mac/issues/4209). - Removed port probing from dashboard, just unconditionally showing links to ports that should be available. Fixes [docker/for-mac#4264](https://github.com/docker/for-mac/issues/4264). - Docker Desktop now shares `/var/folders` by default as it stores per-user temporary files and caches. - Ceph support has been removed from Docker Desktop to save disk space. - Fixed a performance regression when using shared volumes in 2.2.0.5. Fixes [docker/for-mac#4423]. ## Docker Desktop Community 2.2.0.5 2020-04-02 ### Bug fixes and minor changes - Removed dangling `/usr/local/bin/docker-machine` symlinks which avoids custom installs of Docker Machine being accidentally deleted in future upgrades. Note that if you have installed Docker Machine manually, then the install might have followed the symlink and installed Docker Machine in `/Applications/Docker.app`. In this case, you must manually reinstall Docker Machine after installing this version of Docker Desktop. Fixes [docker/for-mac#4208](https://github.com/docker/for-mac/issues/4208). ## Docker Desktop Community 2.2.0.4 2020-03-13 ### Upgrades - [Docker 19.03.8](https://github.com/docker/docker-ce/releases/tag/v19.03.8) ### Bug fixes and minor changes - Kubernetes: Persistent volumes created by claims are now stored in the virtual machine. Fixes [docker/for-win#5665](https://github.com/docker/for-win/issues/5665). - Fixed an issue which caused Docker Desktop Dashboard to attempt connecting to all exposed ports inside a container. Fixes [docker/for-mac#4264](https://github.com/docker/for-mac/issues/4264). ## Docker Desktop Community 2.2.0.3 2020-02-11 ### Upgrades - [Docker Compose 1.25.4](https://github.com/docker/compose/releases/tag/1.25.4) - [Go 1.12.16](https://golang.org/doc/devel/release.html#go1.12) ## Docker Desktop Community 2.2.0.0 2020-01-21 Docker Desktop 2.2.0.0 contains a Kubernetes upgrade. Your local Kubernetes cluster will be reset after installing this version. ### Upgrades - [Docker Compose 1.25.2](https://github.com/docker/compose/releases/tag/1.25.2) - [Kubernetes 1.15.5](https://github.com/kubernetes/kubernetes/releases/tag/v1.15.5) - Linux kernel 4.19.76 - [QEMU 4.0.1](https://github.com/docker/binfmt) ### New - **Docker Desktop Dashboard:** The new Docker Desktop **Dashboard** provides a user-friendly interface which enables you to interact with containers and applications, and manage the lifecycle of your applications directly from the UI. In addition, it allows you to access the logs, view container details, and monitor resource utilization to explore the container behavior.
