# Deprecated Engine Features
The following list of features are deprecated in Engine.
To learn more about Docker Engine's deprecation policy,
see [Feature Deprecation Policy](https://docs.docker.com/engine/#feature-deprecation-policy).
The following list of features are deprecated in Engine. To learn more about Docker
Engine's deprecation policy, see [Feature Deprecation Policy](https://docs.docker.com/engine/#feature-deprecation-policy).
The table below provides an overview of the current status of deprecated features:
- **Deprecated**: the feature is marked "deprecated" and should no longer be used.
The feature may be removed, disabled, or change behavior in a future release.
The _"Deprecated"_ column contains the release in which the feature was marked
deprecated, whereas the _"Remove"_ column contains a tentative release in which
the feature is to be removed. If no release is included in the _"Remove"_ column,
the release is yet to be decided on.
- **Removed**: the feature was removed, disabled, or hidden. Refer to the linked
section for details. Some features are "soft" deprecated, which means that they
remain functional for backward compatibility, and to allow users to migrate to
alternatives. In such cases, a warning may be printed, and users should not rely
on this feature.

### Legacy "overlay" storage driver
**Deprecated in Release: v18.09.0**
### `docker engine` subcommands
The `overlay` storage driver is deprecated in favor of the `overlay2` storage
driver, which has all the benefits of `overlay`, without its limitations (excessive
inode consumption). The legacy `overlay` storage driver will be removed in a future
release. Users of the `overlay` storage driver should migrate to the `overlay2`
storage driver.
**Deprecated in Release: v19.03.0**
The legacy `overlay` storage driver allowed using overlayFS-backed filesystems
on pre 4.x kernels. Now that all supported distributions are able to run `overlay2`
(as they are either on kernel 4.x, or have support for multiple lowerdirs
backported), there is no reason to keep maintaining the `overlay` storage driver.
**Target For Removal In Release: v20.03.0**
### device mapper storage driver
The `docker engine activate`, `docker engine check`, and `docker engine update`
provided an alternative installation method to upgrade Docker Community engines
to Docker Enterprise, using an image-based distribution of the Docker Engine.
**Deprecated in Release: v18.09.0**
This feature was only available on Linux, and only when executed on a local node.
Given the limitations of this feature, and the feature not getting widely adopted,
the `docker engine` subcommands will be removed, in favor of installation through
standard package managers.
The `devicemapper` storage driver is deprecated in favor of `overlay2`, and will
be removed in a future release. Users of the `devicemapper` storage driver are
recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver.
The `devicemapper` storage driver facilitates running Docker on older (3.x) kernels
that have no support for other storage drivers (such as overlay2, or AUFS).
### Top-level `docker deploy` subcommand (experimental)
**Deprecated in Release: v19.03.0**
**Target For Removal In Release: v20.03.0**
The top-level `docker deploy` command (using the "Docker Application Bundle"
(.dab) file format was introduced as an experimental feature in Docker 1.13 /
17.03, but superseded by support for Docker Compose files using the `docker stack deploy`
subcommand.
### `docker stack deploy` using "dab" files (experimental)

With no development being done on this feature, and no active use of the file
format, support for the DAB file format and the top-level docker deploy command
(hidden by default in 19.03), will be removed, in favour of `docker stack deploy`
using compose files.
Now that support for `overlay2` is added 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 `devicemapper` storage driver.

### Interacting with V1 registries
**Disabled By Default In Release: v17.06**
**Removed In Release: v17.12**
Version 1.8.3 added a flag (`--disable-legacy-registry=false`) which prevents the
docker daemon from `pull`, `push`, and `login` operations against v1
registries. Though enabled by default, this signals the intent to deprecate
the v1 protocol.
Support for the v1 protocol to the public registry was removed in 1.13. Any
mirror configurations using v1 should be updated to use a
[v2 registry mirror](https://docs.docker.com/registry/recipes/mirror/).
Starting with Docker 17.12, support for V1 registries has been removed, and the
