Fixed [docker/for-win#6206](https://github.com/docker/for-win/issues/6206) and [docker/for-mac#4415](https://github.com/docker/for-mac/issues/4415). - Fixed a bug where containers disappeared from the UI when Kubernetes context is invalid. 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 Stable channel from the Docker Desktop UI. - Made the embedded terminal resizable. - Fixed bug where diagnostic upload would fail if the username contained spaces. ## Docker Desktop Community 2.2.3.0 2020-04-02 ### Upgrades - [Docker 19.03.8](https://github.com/docker/docker-ce/releases/tag/v19.03.8) - [Docker Compose 1.26.0-rc3](https://github.com/docker/compose/releases/tag/1.26.0-rc3) - [Linux 4.19.76](https://hub.docker.com/layers/docker/for-desktop-kernel/4.19.76-4e5d9e5f3bde0abf236f97e4a81b029ae0f5f6e7-amd64/images/sha256-11dc0f6ee3187088219ba1463ebb378f5093a7d98f176ddfd62dd6b741c2dd2d?context=repo) ### New - Docker Desktop introduces a new onboarding tutorial upon first startup. The Quick Start tutorial guides users to get started with Docker in a few easy steps. It includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub. ### Bug fixes and minor changes > Docker Desktop Edge 2.2.3.0 fixes 7 issues reported on the [docker/for-mac](https://github.com/docker/for-mac/issues) GitHub repository. - Reduced the size of the Docker Desktop installer from 710 MB to 445 MB. - 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). - 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). - Capturing diagnostics is now faster and easier. - 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). - 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). - 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).

A new onboarding tutorial was added. The installer size was reduced, dangling symlinks were removed, and various bugs were fixed related to the Docker UI, AHCI deadlock, diagnostics, port exposure, Kubernetes persistent volumes, and port probing in the dashboard.
