+## Configuration for pushing non-distributable artifacts
+
+**Deprecated in Release: v28.0**
+**Target For Removal In Release: v29.0**
+
+Non-distributable artifacts (also called foreign layers) were introduced in
+docker v1.12 to accommodate Windows images for which the EULA did not allow
+layers to be distributed through registries other than those hosted by Microsoft.
+The concept of foreign / non-distributable layers was adopted by the OCI distribution
+spec in [oci#233]. These restrictions were relaxed later to allow distributing
+these images through non-public registries, for which a configuration was added
+in Docker v17.0.6.0.
+
+In 2022, Microsoft updated the EULA and [removed these restrictions][msft-3645201],
+followed by the OCI distribution specification deprecating foreign layers in [oci#965].
+In 2023, Microsoft [removed the use of foreign data layers][msft-3846833] for their images,
+making this functionality obsolete.
+
+Docker v28.0 deprecates the `--allow-nondistributable-artifacts` daemon flag and
+corresponding `allow-nondistributable-artifacts` field in `daemon.json`. Setting
+either option no longer takes an effect, but a deprecation warning log is added
+to raise awareness about the deprecation. This warning is planned to become an
+error in the Docker v29.0.
+
+Users currently using these options are therefore recommended to remove this
+option from their configuration to prevent the daemon from starting when
+upgrading to Docker v29.0.
+
+The `AllowNondistributableArtifactsCIDRs` and `AllowNondistributableArtifactsHostnames`
+fields in the `RegistryConfig` of the `GET /info` API response are also deprecated.
+For API version v1.48 and lower, the fields are still included in the response
+but always `null`. In API version v1.49 and higher, the field will be omitted
+entirely.

-### Allow push of non-distributable artifacts
-
-Some images (e.g., Windows base images) contain artifacts whose distribution is
-restricted by license. When these images are pushed to a registry, restricted
-artifacts are not included.
-
-To override this behavior for specific registries, use the
-`--allow-nondistributable-artifacts` option in one of the following forms:
-
-* `--allow-nondistributable-artifacts myregistry:5000` tells the Docker daemon
-  to push non-distributable artifacts to myregistry:5000.
-* `--allow-nondistributable-artifacts 10.1.0.0/16` tells the Docker daemon to
-  push non-distributable artifacts to all registries whose resolved IP address
-  is within the subnet described by the CIDR syntax.
-
-This option can be used multiple times.
-
-This option is useful when pushing images containing non-distributable artifacts
-to a registry on an air-gapped network so hosts on that network can pull the
-images without connecting to another server.
-
-> [!WARNING]
-> Non-distributable artifacts typically have restrictions on how
-> and where they can be distributed and shared. Only use this feature to push
-> artifacts to private registries and ensure that you are in compliance with
-> any terms that cover redistributing non-distributable artifacts.
