Released on March 29, 2026, hellorest v1.3.0 brings key improvements to how you monitor and deploy your minimal REST API. This release focuses on observability and portability, making it easier than ever to verify your deployment version and run hellorest across a wider variety of hardware.

What’s new

  • Version Tracking via HTTP Headers: The GET / endpoint now returns an X-App-Version header. You can now instantly verify which version of the application is running in your environment without needing to inspect container metadata.
  • Multi-Architecture Docker Support: We’ve expanded our build process to support multiple architectures. Whether you are deploying on traditional x86 servers or ARM-based cloud instances and local hardware, the latest Docker images are ready for you.
  • Modernized Core: We’ve updated the underlying engine to Go 1.26.1 and transitioned our base image to Debian 13, ensuring a more secure and performant runtime environment.

Why it matters

For developers and DevOps engineers, knowing exactly what is running in production is critical. The new version header eliminates guesswork during deployments. Furthermore, the shift to multi-arch support means hellorest is now truly portable, fitting seamlessly into any modern infrastructure stack, from the edge to the cloud.
