v2.2.0+node25.9.0 — Node.js 25.9.0 and CI Workflow Updates

Runtime Node v2.2.0+node25.9.0

Secure, Distroless, Multi-Arch Node.js Runtime. Built from Scratch.

This is the second minor release on the Node.js 25 maintenance line. The Node.js runtime is upgraded from 25.8.2 to 25.9.0. This release also moves PR image testing from Docker Hub-pushed images to OCI artifact handoff, updates docker/build-push-action to v7 in both workflows, enables signed mode=max provenance and SBOM attestations in the release workflow, and refreshes documentation examples and CI/CD tooling references to match the current release state.

What's New

• Updated FROM node:25.8.2-alpine3.23 AS builder to FROM node:25.9.0-alpine3.23 AS builder in Dockerfile, upgrading the Node.js runtime bundled into the final scratch image from 25.8.2 to 25.9.0.
• Updated .github/workflows/pr-tests.yml to stop pushing PR images to Docker Hub by changing the Build Image step from push: true to push: false with outputs: type=oci,dest=image.tar, and added Upload Docker Image Artifact, Download Docker Image Artifact, Extract single-arch image with Skopeo, and artifact-clean-up to hand the image between jobs as an OCI artifact.
• Updated .github/workflows/pr-tests.yml from uses: docker/build-push-action@v6 to uses: docker/build-push-action@v7 in the Build Image step, and updated .github/workflows/deployment.yml from uses: docker/build-push-action@v5 to uses: docker/build-push-action@v7 in the Build and push (multi-registry, multi-platform) step.
• Added id-token: write to the top-level permissions: block in .github/workflows/deployment.yml and replaced provenance: true and sbom: true with attests: entries type=provenance,mode=max and type=sbom,mode=max in the Build and push (multi-registry, multi-platform) step.
• Updated the Node.js Version Bumps example in CONTRIBUTING.md from node:25.8.2-alpine3.23 to node:25.9.0-alpine3.23, updated the Versioning and Tags example in README.md from v2.1.3+node25.8.2 to v2.2.0+node25.9.0, and added actions/upload-artifact, actions/download-artifact, geekyeggo/delete-artifact, chrnorm/deployment-action, and chrnorm/deployment-status to the CI/CD & Build Tooling section of README.md.
