The `~/.dockercfg` file was replaced by `~/.docker/config.json` in 2015
(github.com/docker/docker/commit/18c9b6c6455f116ae59cde8544413b3d7d294a5e),
but the CLI still falls back to checking if this file exists if no current
(`~/.docker/config.json`) file was found.
Given that no version of the CLI since Docker v1.7.0 has created this file,
and if such a file exists, it means someone hasn't re-authenticated for
5 years, it's probably safe to remove this fallback.

This feature allowed using an encrypted private key with a supplied password,
but did not provide additional security as the encryption is known to be broken,
and the key is sitting next to the password in the filesystem. Users are recommended
to decrypt the private key, and store it un-encrypted to continue using it.

Docker Engine v20.10 and up includes optimizations to verify if images in the
local image cache need updating before pulling, preventing the Docker Engine
from making unnecessary API requests. These optimizations require the container
image registry to conform to the Open Container Initiative Distribution Specification
(https://github.com/opencontainers/distribution-spec).
While most registries conform to the specification, we encountered some registries
to be non-compliant, resulting in `docker pull` to fail.
As a temporary solution, Docker Engine v20.10 includes a fallback mechanism to
allow `docker pull` to be functional when using a non-compliant registry. A
warning message is printed in this situation:
WARNING Failed to pull manifest by the resolved digest. This registry does not
appear to conform to the distribution registry specification; falling back to
pull by tag. This fallback is DEPRECATED, and will be removed in a future
release.
The fallback is added to allow users to either migrate their images to a compliant
registry, or for these registries to become compliant.
Note that this fallback only addresses failures on `docker pull`. Other commands,
such as `docker stack deploy`, or pulling images with `containerd` will continue
to fail.
Given that other functionality is still broken with these registries, we consider
this fallback a _temporary_ solution, and will remove the fallback in an upcoming
major release.

Docker v17.07 introduced an experimental `--stream` flag on `docker build` which
allowed the build-context to be incrementally sent to the daemon, instead of
unconditionally sending the whole build-context.
This functionality has been reimplemented as part of BuildKit, which uses streaming
by default and the `--stream` option will be ignored when using the classic builder,
printing a deprecation warning instead.
Users that want to use this feature are encouraged to enable BuildKit by setting
the `DOCKER_BUILDKIT=1` environment variable or through the daemon or CLI configuration
files.

The Dockerfile `ENV` instruction allows values to be set using either `ENV name=value`
or `ENV name value`. The latter (`ENV name value`) form can be ambiguous, for example,
the following defines a single env-variable (`ONE`) with value `"TWO= THREE=world"`,
but may have intended to be setting three env-vars:
ENV ONE TWO= THREE=world
This format also does not allow setting multiple environment-variables in a single
`ENV` line in the Dockerfile.
Use of the `ENV name value` syntax is discouraged, and may be removed in a future
release. Users are encouraged to update their Dockerfiles to use the `ENV name=value`
syntax, for example:
ENV ONE="" TWO="" THREE="world"

The docker CLI up until v1.7.0 used the `~/.dockercfg` file to store credentials
after authenticating to a registry (`docker login`). Docker v1.7.0 replaced this
file with a new CLI configuration file, located in `~/.docker/config.json`. When
implementing the new configuration file, the old file (and file-format) was kept
as a fall-back, to assist existing users with migrating to the new file.
Given that the old file format encourages insecure storage of credentials
(credentials are stored unencrypted), and that no version of the CLI since
Docker v1.7.0 has created this file, the file is marked deprecated, and support
for this file will be removed in a future release.

The deprecation policy was written when we had monthly releases
(edge+stable), and stable releases were released every 3 months.
The release cadence has changed to be longer than 3 months for
stable releases, so adjusting the policy accordingly.
Note that the policy continues to be "at least x releases", so
even though we _can_ remove a feature after one release, it does
not mean we _must_ remove it: announcing deprecations early helps
users migrate away from features we do not intent to support in
future.

The `aufs` storage driver is deprecated in favor of `overlay2`, and will
be removed in a future release. Users of the `aufs` storage driver are
recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver.
The `aufs` storage driver facilitates running Docker on distros that have no
support for OverlayFS, such as Ubuntu 14.04 LTS, which originally shipped with
a 3.14 kernel.
Now that Ubuntu 14.04 is no longer a supported distro for Docker, and `overlay2`
is available to all supported distros (as they are either on kernel 4.x, or have
support for multiple lowerdirs backported), there is no reason to continue
maintenance of the `aufs` storage driver.

Commit 330a0035334871d92207b583c1c36d52a244753f added a `--detach=false` option
to various service-related commands, with the intent to make this the default in
a future version (17.09).
This patch changes the default to use "interactive" (non-detached), allowing
users to override this by setting the `--detach` option.
To prevent problems when connecting to older daemon versions (17.05 and below,
see commit db60f25561), the detach option is
ignored for those versions, and detach is always true.
Before this change, a warning was printed to announce the upcoming default:
$ docker service create nginx:alpine
saxiyn3pe559d753730zr0xer
Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
After this change, no warning is printed, but `--detach` is disabled;
$ docker service create nginx:alpine
y9jujwzozi0hwgj5yaadzliq6
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]

Setting the `--detach` flag makes the cli use the pre-17.06 behavior:
$ docker service create --detach nginx:alpine

This fix tries to address the issue raised in 24392 where
labels with duplicate keys exist in `docker info`, which
contradicts with the specifications in the docs.
The reason for duplicate keys is that labels are stored as
slice of strings in the format of `A=B` (and the input/output).
This fix tries to address this issue by checking conflict
labels when daemon started, and remove duplicate labels (K-V).
The existing `/info` API has not been changed.
An additional integration test has been added to cover the
changes in this fix.
