Multi-Platform Docker Image Build (linux/amd64 + linux/arm64)

The official Docker image is now published as a multi-platform manifest supporting both linux/amd64 and linux/arm64. Pulls on ARM64 hosts (e.g., Apple Silicon, AWS Graviton, Raspberry Pi) will automatically receive a native binary without any extra flags.

✨ Features

• ARM64 Docker image support. The ghcr.io/oocx/tfplan2md image now includes a native linux/arm64 layer alongside the existing linux/amd64 layer. Docker automatically selects the right layer based on the host architecture.
