Docker Engine 26.0.0 Release Notes: API Updates, Packaging and Removals

- To preserve backwards compatibility, read-only mounts are not recursive by default when using older clients (API version < v1.44). [moby/moby#47391](https://github.com/moby/moby/pull/47391) - `GET /images/{id}/json` omits the `Created` field (previously it was `0001-01-01T00:00:00Z`) if the `Created` field is missing from the image config. [moby/moby#47451](https://github.com/moby/moby/pull/47451) - Populate a missing `Created` field in `GET /images/{id}/json` with `0001-01-01T00:00:00Z` for API version <= 1.43. [moby/moby#47387](https://github.com/moby/moby/pull/47387) - The `is_automated` field in the `POST /images/search` endpoint results is always `false` now. Consequently, searching for `is-automated=true` will yield no results, while `is-automated=false` will be a no-op. [moby/moby#47465](https://github.com/moby/moby/pull/47465) - Remove `Container` and `ContainerConfig` fields from the `GET /images/{name}/json` response. [moby/moby#47430](https://github.com/moby/moby/pull/47430) ### Packaging updates - Update BuildKit to [v0.13.1](https://github.com/moby/buildkit/releases/tag/v0.13.1). [moby/moby#47582](https://github.com/moby/moby/pull/47582) - Update Buildx to [v0.13.1](https://github.com/docker/buildx/releases/tag/v0.13.1). [docker/docker-ce-packaging#1000](https://github.com/docker/docker-ce-packaging/pull/1000) - Update Compose to [v2.25.0](https://github.com/docker/compose/releases/tag/v2.25.0). [docker/docker-ce-packaging#1002](https://github.com/docker/docker-ce-packaging/pull/1002) - Update Go runtime to [1.21.8](https://go.dev/doc/devel/release#go1.21.8).

[moby/moby#47508](https://github.com/moby/moby/pull/47504) - Update containerd to v1.7.13 (static binaries only) [moby/moby#47278](https://github.com/moby/moby/pull/47278) - Update runc binary to v1.1.12 [moby/moby#47268](https://github.com/moby/moby/pull/47268) - Update OTel to v0.46.1 / v1.21.0 [moby/moby#47245](https://github.com/moby/moby/pull/47245) ### Removed - Remove `Container` and `ContainerConfig` fields from the `GET /images/{name}/json` response. [moby/moby#47430](https://github.com/moby/moby/pull/47430) - Deprecate the ability to accept remote TCP connections without TLS. [Deprecation notice](https://github.com/docker/cli/tree/v26.0.0/deprecation.md#unauthenticated-tcp-connections) [docker/cli#4928](https://github.com/docker/cli/pull/4928) [moby/moby#47556](https://github.com/moby/moby/pull/47556).
