Minor Changes

• 9fb2976: Add services as the canonical multi-service project configuration and keep experimentalServicesV2 as a deprecated backwards-compatible alias.

Patch Changes

• 186014d: Add an experimental container service runtime. A service with
  runtime: "container" either builds its Dockerfile/Containerfile and pushes
  the resulting OCI image to the Vercel Container Registry (VCR), or passes a
  prebuilt image reference through as build output.

  • @vercel/container (new builder): authenticates to VCR with the project's
    VERCEL_OIDC_TOKEN, ensures the repository exists, builds and pushes the
    image, and emits a digest-pinned reference in handler (container functions
    are type: "Lambda" with runtime: "container"; the platform surfaces
    handler as the image downstream). Uses docker on developer machines and
    buildah (daemonless) in the Vercel build container behind a shared
    ContainerEngine interface. Supports vc dev via startDevServer (local
    build/run, env parity, log forwarding) and prepareCache for buildah layer
    reuse between builds. Build flow is instrumented with tracing spans
    (non-secret diagnostics) and debug logging gated on BUILDER_DEBUG.
  • @vercel/build-utils: add the ContainerImage build-output type.
  • @vercel/fs-detectors: resolve container services from vercel.json
    (the services config and its deprecated experimentalServices /
    experimentalServicesV2 aliases). A Dockerfile, Containerfile, or
    *.dockerfile entrypoint triggers a build; any other entrypoint is treated as
    a prebuilt OCI image reference.
  • vercel: wire container output into vercel build result writing and
    config validation.

  Buildah specifics in the build container: host networking for RUN steps,
  native overlay storage on the XFS /vercel volume (deferring to the image's
  storage.conf), zstd push compression, and registry credentials read from the
  provisioned auth file when present. Several knobs are available for debugging:
  VERCEL_CONTAINER_ENGINE, VERCEL_VCR_STRICT_STORAGE,
  VERCEL_VCR_DISABLE_LAYER_CACHE, and VERCEL_VCR_FORCE_LOGIN.

• cb0988f: Set the Node.js 20 discontinuation date to October 1, 2026.
