📝 Walkthrough

Walkthrough

This pull request updates the GitHub Actions workflow to enable multi-platform Docker builds by adding a "Set up QEMU" step (docker/setup-qemu-action@v3) and configuring the "Build and push Docker image" step to target linux/amd64 and linux/arm64. It also adds a changeset file declaring a patch release for the package baruchiro/paperless-mcp and notes Docker support for arm64.

61-61: Consider conditional platform builds to optimize CI performance.

The multi-platform configuration is correct and will successfully build for both architectures. However, building for arm64 via QEMU emulation on amd64 runners significantly increases build time. Since this workflow triggers on pull requests, every PR will incur this overhead.

Consider building both platforms only for releases/main pushes, while PRs could build just linux/amd64 for faster validation. This can be achieved using conditional expressions with github.event_name.

Optional: Conditional platform configuration

You could modify the workflow to conditionally set platforms:

Add a step to determine platforms:

- name: Set platforms
  id: platforms
  run: |
    if [ "${{ github.event_name }}" = "pull_request" ]; then
      echo "platforms=linux/amd64" >> $GITHUB_OUTPUT
    else
      echo "platforms=linux/amd64,linux/arm64" >> $GITHUB_OUTPUT
    fi

Then reference it in the build step:

platforms: ${{ steps.platforms.outputs.platforms }}

21-22: QEMU action version is current and appropriate.

docker/setup-qemu-action@v3 is the latest stable major version (currently v3.7.0 as of November 2025). Using the major version tag @v3 ensures the workflow automatically receives patch updates. No known security advisories exist for this action; security monitoring should focus on underlying components (QEMU, Docker, BuildKit, runc) rather than the action itself.

I don't know what npm changed in their security settings, but I can't deploy it and I don't have enough time 🥴
