Docker Desktop Updates: Bug Fixes, Apple Silicon Support, and Known Issues

- Docker Desktop now exposes the host CPU on Apple silicon. Fixes [docker/for-mac#5681](https://github.com/docker/for-mac/issues/5681). - Avoid leaking open ports bound to privileged ports and specific IPs over engine Restart. Fixes [docker/for-mac#5649](https://github.com/docker/for-mac/issues/5649). - Use `vpnkit` with `virtualization.framework` to fix connectivity issues with VPN clients such as Cisco AnyConnect. - Fixed version number missing in update dialog window. - Fixed an issue where the diagnostics were sometimes not uploaded correctly from the **Support** dialog. - Fixed DNS entries for `*.docker.internal` and Kubernetes cluster reset after the VM IP changes. Fixes [docker/for-mac#5707](https://github.com/docker/for-mac/issues/5707), [docker/for-mac#5680](https://github.com/docker/for-mac/issues/5680), [docker/for-mac#5663](https://github.com/docker/for-mac/issues/5663) and [docker/for-mac#5653](https://github.com/docker/for-mac/issues/5653). - Avoid running `com.docker.osxfs` when gRPC FUSE is enabled. Fixes [docker/for-mac#5725](https://github.com/docker/for-mac/issues/5725). ### Known issues - On Apple Silicon in native `arm64` containers, older versions of `libssl` in `debian:buster`, `ubuntu:20.04` and `centos:8` will segfault when connected to some TLS servers, for example `curl https://dl.yarnpkg.com`. The bug is fixed in newer versions of `libssl` in `debian:bullseye`, `ubuntu:21.04` and `fedora:35`. ## Docker Desktop 3.3.3 2021-05-06 ### Upgrades - [Snyk v1.563.0](https://github.com/snyk/snyk/releases/tag/v1.563.0) - [Docker Scan v0.8.0](https://github.com/docker/scan-cli-plugin/releases/tag/v0.8.0) ### Bug fixes and minor changes - Fixed the diagnostics failing to upload from the Troubleshoot screen. ### Docker Desktop 3.3.2 2021-05-03 ### Upgrades - [Compose CLI v1.0.14](https://github.com/docker/compose-cli/tree/v1.0.14) - [Go 1.16.3](https://golang.org/doc/go1.16) - [Docker Compose 1.29.1](https://github.com/docker/compose/releases/tag/1.29.1) - [Docker Engine 20.10.6](/manuals/engine/release-notes/20.10.md#20106) ### Bug fixes and minor changes - Fixed a bug with an Apple chip where the last byte in a network transfer was occasionally lost. - Fixed a bug where a `metrics-port` defined in the engine's `daemon.json` blocks application restart. - Fixed a leak of ephemeral ports. Fixes [docker/for-mac#5611](https://github.com/docker/for-mac/issues/5611). - Emulate a more modern Intel CPU with `qemu` on an Apple chip, for better image compatibility. See [docker/for-mac#5561](https://github.com/docker/for-mac/issues/5561). - Enable buildkit garbage collection by default. - Fixed a bug which blocked binding to port 123. Fixes [docker/for-mac#5589](https://github.com/docker/for-mac/issues/5589). - Disable the HTTP and HTTPS transparent proxies when there is no upstream proxy set. Fixes [docker/for-mac#5572](https://github.com/docker/for-mac/issues/5572). - Revert to the HTTP and HTTPS proxy implementation used in 3.2.2. - Removed the "Deploy Docker Stacks to Kubernetes by default" Kubernetes setting. The component was removed in 2.4.0.0 but we forgot to remove the setting. Fixes [docker/for-mac#4966](https://github.com/docker/for-mac/issues/4966). ## Docker Desktop 3.3.1 2021-04-15 ### New Docker Desktop is now available for Apple silicon as well as Intel chips. This enables developers with their choice of local development environments, and extends development pipelines for ARM-based applications. For more information, see [Docker Desktop for Apple silicon](/manuals/desktop/setup/install/mac-install.md). ### Bug fixes and minor changes - Docker Desktop now ensures the permissions of `/dev/null` and other devices are correctly set to `0666` (`rw-rw-rw-`) inside `--privileged` containers. Fixes [docker/for-mac#5527](https://github.com/docker/for-mac/issues/5527) - Fixed an issue that caused Docker Desktop to fail during startup when it is unable to establish a connection with Docker Hub in the backend. Fixes [docker/for-win#10896](https://github.com/docker/for-win/issues/10896)

This section details updates to Docker Desktop, including bug fixes related to Apple Silicon, port leaks, network transfers, and proxy settings. It highlights the availability of Docker Desktop for Apple silicon and a known issue with `libssl` in older versions on ARM64 containers. The updates also include upgrades to Snyk, Docker Scan, Compose CLI, Go, Docker Compose, and Docker Engine. Additionally, it addresses issues with diagnostics uploads, port binding, and permissions inside `--privileged` containers.
