In August 2025, docker/cagent delivered a key security enhancement: Secure Release Binary Signing. The change introduces a CI workflow step that signs release binaries and adds a 'sign' job to GitHub Actions, coordinating with a private signing workflow and handling upload/download of signed artifacts to ensure cryptographic signing of released binaries, thereby improving release integrity and authenticity. The effort strengthens supply chain security for released binaries and establishes a foundation for auditable, tamper-evident releases.
