### Bug fixes and minor changes

- When sharing Linux directories (`/var`, `/bin`, etc) with containers, Docker Desktop avoids watching paths in the host file system.
- When sharing a file into a container (e.g. `docker run -v ~/.gitconfig`) Docker Desktop does not watch the parent directory. Fixes [docker/for-mac#4981](https://github.com/docker/for-mac/issues/4981).
- gRPC FUSE: fix `chown` when the file is read-only. Fixes `rabbitmq`, see [docker/for-mac#4964](https://github.com/docker/for-mac/issues/4964).

- Docker ECS plugin has been replaced by ECS cloud integration
- Docker UI:
  - The Images view now has search and filter options.
  - You can now push an image to Docker Hub using the Remote repositories drop-down menu.
- WSL 2 files and directories can now be mounted from the Windows Docker CLI with e.g. `docker run -v \\wsl$\Ubuntu\my-files:/my-files ...`.

### Removal

- Support for MacOS 10.13 has ended, you will need to update your system to keep using Docker Desktop.

### Upgrades

- [Alpine 3.12](https://alpinelinux.org/posts/Alpine-3.12.0-released.html)
- [Kubernetes 1.18.8](https://github.com/kubernetes/kubernetes/releases/tag/v1.18.8)

### Bug fixes and minor changes

- Fixed a Mac CPU usage bug by removing the serial console from `hyperkit`, see [docker/roadmap#12]( https://github.com/docker/roadmap/issues/12#issuecomment-663163280). To open a shell in the VM use either `nc -U ~/Library/Containers/com.docker.docker/Data/debug-shell.sock` (on Mac) or `putty -serial \\.\pipe\dockerDebugShell` (on Windows).

## Docker Desktop Community 2.3.5.0
2020-08-21

### New

- The **Images** view on the Dashboard now allows you to interact with images on Docker Hub. You can now pull a remote repository with specific tags from Docker Hub, or view the details of the repository on the Docker Hub page. To access the new Images view, from the Docker menu, select **Dashboard** > **Images**.

- Docker Desktop now enables BuildKit by default after a reset to factory defaults. To revert to the old docker build experience, go to **Preferences** > **Docker Engine** and then disable the BuildKit feature.

- Docker Desktop now uses **gRPC-FUSE** for file sharing by default. This has much faster file sharing and uses much less CPU than `osxfs`, especially when there are lots of file events on the host. To switch back to `osxfs`, go to **Preferences** > **General** and disable gRPC-FUSE.

### Upgrades

- [Go 1.14.7](https://github.com/golang/go/issues?q=milestone:Go1.14.7+label:CherryPickApproved)
- [Docker ECS integration v1.0.0-beta.5](https://github.com/docker/ecs-plugin/releases/tag/v1.0.0-beta.5)
- [Docker Engine 19.03.13-beta2](https://github.com/docker/docker-ce/releases/tag/v19.03.13-beta2)
- [Docker ACI integration 0.1.12](https://github.com/docker/aci-integration-beta/releases/tag/v0.1.12)

### Removal

- The Mutagen file sync feature that we have been experimenting with in recent Edge releases has been removed. Thanks to everyone who has provided feedback on this feature. We are reconsidering how to integrate it based on the feedback we have received so far.

### Bug fixes and minor changes

- Moved **Dashboard** to the top of the whale menu.
- Improved the error handling when `dockerd` crashes.
- Fixed minor bugs in the **Images** view.

## Docker Desktop Community 2.3.4.0
2020-07-28

### New

- Docker Desktop introduces the new **Images** view to the Docker Dashboard. The Images view allows users to view a list of Docker images on the disk, run an image as a container, pull the latest version of an image from Docker Hub, inspect images, and remove any unwanted images from the disk.

  To access the new Images view, from the Docker menu, select **Dashboard** > **Images**.

### Upgrades

- [Docker ECS integration v1.0.0-beta.4](https://github.com/docker/ecs-plugin/releases/tag/v1.0.0-beta.4)

### Bug fixes and minor changes

- Copying the container logs from the dashboard does not copy the ANSI color codes to the clipboard anymore.
- Mutagen two-way sync now uses `.dockersyncignore` rather than `.dockerignore` to exclude files.

## Docker Desktop Community 2.3.3.2
2020-07-21

### Upgrades

- [Docker ECS integration v1.0.0-beta.2](https://github.com/docker/ecs-plugin/releases/tag/v1.0.0-beta.2)
- [Docker ACI integration 0.1.10](https://github.com/docker/aci-integration-beta/releases/tag/v0.1.10)

### Bug fixes and minor changes

- Mutagen uses the `.dockerignore` file when creating a session to filter the list of synchronized files. See [docker/for-mac#4621](https://github.com/docker/for-mac/issues/4621).
- Docker CLI commands can now bypass any active Mutagen synchronization for volumes using `:cached`. See [docker/for-mac#1592](https://github.com/docker/for-mac/issues/1592#issuecomment-651309816).

## Docker Desktop Community 2.3.3.0
2020-07-09

### Upgrades

- Beta release of Docker ECS integration v1.0.0-beta.1
- [Docker ACI integration v0.1.7](https://github.com/docker/aci-integration-beta/releases/tag/v0.1.7)
- [Docker Compose 1.26.2](https://github.com/docker/compose/releases/tag/1.26.2)

### Bug fixes and minor changes

- 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).
- Fixed an incompatibility between `hyperkit` and `osquery` which resulted in excessive `hyperkit` CPU usage. See [docker/for-mac#3499](https://github.com/docker/for-mac/issues/3499#issuecomment-639140844)
- Docker Desktop now respects consistency flags `cached`, `delegated`, `consistent` even when in a list of options (for example, `z,delegated`). See [docker/for-mac#4718](https://github.com/docker/for-mac/issues/4718).
- 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.

- 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).

### Known issues

- Loopback and unspecified IPv6 addresses (`::` and `::1`) within a container do not currently work. Some web servers and other programs may be using these addresses in their configuration files.

### Bug fixes and minor changes

- Fixed port forwarding when containers are using `overlay` networks.
- Fixed a container start error when a container has more than one port with an arbitrary or not-yet-configured external port number. For example, `docker run -p 80 -p 443 nginx`. Fixes [docker/for-win#4935](https://github.com/docker/for-win/issues/4935) and [docker/compose#6998](https://github.com/docker/compose/issues/6998).

## Docker Desktop Community 2.1.5.0
2019-11-04


This release contains a Kubernetes upgrade. Note that your local Kubernetes cluster will be reset after installation.

### Upgrades

- [Kubernetes 1.15.5](https://github.com/kubernetes/kubernetes/releases/tag/v1.15.5)
- [Docker Compose 1.25.0-rc4](https://github.com/docker/compose/releases/tag/1.25.0-rc4)
- Linux kernel 4.19.76

### 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.

To access the new Dashboard UI, select the Docker menu from the Mac menu bar and then click **Dashboard**.

### Bug fixes and minor changes

Fixed an issue that caused VMs running on older hardware with macOS Catalina to fail on startup with the error `processor does not support desired secondary processor-based controls`.

### Known issues

- When you start a Docker Compose application and then start a Docker App which has the same name as the Compose application, Docker Desktop displays only one application on the Dashboard. However, when you expand the application, containers that belong to both applications are displayed on the Dashboard.

- When you deploy a Docker App with multiple containers on Kubernetes, Docker Desktop displays each Pod as an application on the Dashboard.

* Upgrades
  - [Docker 17.11.0-ce](https://github.com/docker/docker-ce/releases/tag/v17.11.0-ce)

### Docker Community Edition 17.11.0-ce-rc4-mac39 2017-11-17

  - Linux kernel 4.9.60

* Bug fixes and minor changes
  - Fix login into private repository with certificate issue. [docker/for-mac#2201](https://github.com/docker/for-mac/issues/2201)

* New
  - For systems running APFS on SSD on High Sierra, use `raw` format virtual machine disks by default. This increases disk throughput (from 320MiB/sec to 600MiB/sec in `dd` on a 2015 MacBook Pro) and disk space handling.
  Existing disks are kept in qcow format, if you want to switch to raw format you need to "Reset to factory defaults". To query the space usage of the file, use a command like:
  `$ cd ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/`
  `$ ls -ls Docker.raw`
  `3944768 -rw-r--r--@ 1 user  staff  68719476736 Nov 16 11:19 Docker.raw`
  The first number (`3944768`) is the allocated space in blocks; the larger number `68719476736` is the maximum total amount of space the file may consume in future in bytes.
