Released on May 22, 2026, goenvecho v1.4.0 brings a focused set of improvements aimed at increasing operational transparency and keeping the application’s foundation current. This release introduces native version tracking, making it easier for developers to verify exactly which version of the tool is running in their containerized environments.

What’s new

The headline feature of v1.4.0 is the introduction of Application Versioning. The tool now tracks its own version and exposes it directly through the HTTP interface. Whenever you make a request to the root endpoint, the response will now include an X-App-Version header containing the current version of goenvecho.

Beyond versioning, we’ve modernized the underlying stack:

  • Go 1.26: The application has been updated to target Go 1.26, ensuring we leverage the latest language improvements and compiler optimizations.
  • Debian 13 Base: We’ve bumped the Docker runtime image to base-debian13, providing a more recent and secure base for our distroless images.

Why it matters

For developers managing multiple environments or clusters, knowing exactly which version of a debugging tool is deployed can be surprisingly difficult. By exposing the version in the X-App-Version header, goenvecho removes the guesswork, allowing for faster troubleshooting and more reliable deployment verification.

The updates to the Go toolchain and the Debian base image are equally important. By staying current with these dependencies, goenvecho maintains a strong security posture and ensures compatibility with the latest container orchestration standards, all while keeping the binary lightweight and efficient.

Getting started with v1.4.0

Upgrading to the latest version is simple. You can pull the updated image directly from the GitHub Container Registry:

docker pull ghcr.io/unitvectory-labs/goenvecho:v1.4.0

Whether you’re using it for quick environment checks or as part of a larger debugging suite, v1.4.0 ensures that goenvecho remains a reliable, transparent, and secure companion for your development workflow.
