+This document provides an overview of Docker features, products, and
+open-source projects that have been deprecated, retired, or transitioned.
+
+> [!NOTE]
+>
+> This page does not cover deprecated and removed Docker Engine features.
+> For a detailed list of deprecated Docker Engine features, refer to the
+> [Docker Engine Deprecated Features documentation](/manuals/engine/deprecated.md).
+
+## Products and features
+
+Support for these deprecated or retired features is no longer provided by
+Docker, Inc. The projects that have been transitioned to third parties continue
+to receive updates from their new maintainers.
+
+### Docker Machine
+
+Docker Machine was a tool for provisioning and managing Docker hosts across
+various platforms, including virtual machines and cloud providers. It is no
+longer maintained, and users are encouraged to use [Docker Desktop](/manuals/desktop/_index.md)
+or [Docker Engine](/manuals/engine/_index.md) directly on supported platforms.
+Machine's approach to creating and configuring hosts has been superseded by
+more modern workflows that integrate more closely with Docker Desktop.
+
+### Docker Toolbox
+
+Docker Toolbox was used on older systems where Docker Desktop could not run. It
+bundled Docker Machine, Docker Engine, and Docker Compose into a single
+installer. Toolbox is no longer maintained and is effectively replaced by
+[Docker Desktop](/manuals/desktop/_index.md) on current systems. References to
+Docker Toolbox occasionally appear in older documentation or community
+tutorials, but it is not recommended for new installations.
+
+### Docker Cloud integrations
+
+Docker previously offered integrations for Amazon's Elastic Container Service
+(ECS) and Azure Container Instances (ACI) to streamline container workflows.
+These integrations have been deprecated, and users should now rely on native
+cloud tools or third-party solutions to manage their workloads. The move toward
+platform-specific or universal orchestration tools reduced the need for
+specialized Docker Cloud integrations.
+
+You can still view the relevant documentation for these integrations in the
+[Compose CLI repository](https://github.com/docker-archive/compose-cli/tree/main/docs).
+
+### Docker Enterprise Edition
+
+Docker Enterprise Edition (EE) was Docker's commercial platform for deploying
+and managing large-scale container environments. It was acquired by Mirantis in
+2019, and users looking for enterprise-level functionality can now explore
+Mirantis Kubernetes Engine or other products offered by Mirantis. Much of the
+technology and features found in Docker EE have been absorbed into the Mirantis
+product line.
+
+> [!NOTE]  
+> For information about enterprise-level features offered by Docker today,
+> see the [Docker Business subscription](/manuals/subscription/details.md#docker-business).
+
+### Docker Data Center and Docker Trusted Registry
+
+Docker Data Center (DDC) was an umbrella term that encompassed Docker Universal
+Control Plane (UCP) and Docker Trusted Registry (DTR). These components
+provided a full-stack solution for managing containers, security, and registry
+services in enterprise environments. They are now under the Mirantis portfolio
+following the Docker Enterprise acquisition. Users still encountering
+references to DDC, UCP, or DTR should refer to Mirantis's documentation for
+guidance on modern equivalents.
+
+### Dev Environments
+
+Dev Environments was a feature introduced in Docker Desktop that allowed
+developers to spin up development environments quickly. This feature is no
+longer under active development. Similar workflows can be achieved through
+Docker Compose or by creating custom configurations tailored to specific
+project requirements.
+
+## Open source projects
+
+Several open-source projects originally maintained by Docker have been
+archived, discontinued, or transitioned to other maintainers or organizations.
+
+### Registry (now CNCF Distribution)
+
+The Docker Registry served as the open-source implementation of a container
+image registry. It was donated to the Cloud Native Computing Foundation (CNCF)
+in 2019 and is maintained under the name "Distribution." It remains a
+cornerstone for managing and distributing container images.
+
+[CNCF Distribution](https://github.com/distribution/distribution)
+
+### Docker Compose v1 (replaced by Compose v2)
+
+Docker Compose v1 (`docker-compose`), a Python-based tool for defining
+multi-container applications, has been superseded by Compose v2 (`docker
+compose`), which is written in Go and integrates with the Docker CLI. Compose
+v1 is no longer maintained, and users should migrate to Compose v2.
+
+[Compose v2 Documentation](/manuals/compose/_index.md)
+
+### InfraKit
+
+InfraKit was an open-source toolkit designed to manage declarative
+infrastructure and automate container deployments. It has been archived, and
+users are encouraged to explore tools such as Terraform for infrastructure
+provisioning and orchestration.
+
+[InfraKit GitHub Repository](https://github.com/docker/infrakit)
+
+### Docker Notary (now CNCF Notary)
+
+Docker Notary was a system for signing and verifying the authenticity of
+container content. It was donated to the CNCF in 2017 and continues to be
+developed as "Notary." Users seeking secure content verification should consult
+the CNCF Notary project.
+
+[CNCF Notary](https://github.com/notaryproject/notary)
+
+### SwarmKit
+
+SwarmKit powers Docker Swarm mode by providing orchestration for container
+deployments. While Swarm mode remains functional, development has slowed in
+favor of Kubernetes-based solutions. Individuals evaluating container
+orchestration options should investigate whether SwarmKit meets modern workload
+requirements.
