On February 15, 2025, we released iapheaders v0.4.1, a maintenance update that keeps the project running on the latest Go runtime.

What’s New

This release focuses on infrastructure and build hygiene rather than new features. The primary change is upgrading the Go version from 1.23.5 to 1.24.0 across all build artifacts:

  • Updated Go runtime in go.mod, Dockerfile, and CI workflows
  • Refined .dockerignore to exclude the .github/ directory from Docker builds

These changes ensure the application benefits from the latest Go language improvements, performance enhancements, and security patches included in the 1.24.x series.

Why It Matters

While this release doesn’t introduce visible feature changes, staying current with runtime updates is essential for maintaining a secure and performant application. The Go 1.24.0 upgrade brings:

  • Security improvements from cumulative Go security patches
  • Performance optimizations in the Go runtime itself
  • CI/CD reliability by using actively maintained toolchain versions

For users deploying iapheaders as a container image (ghcr.io/unitvectory-labs/iapheaders), no action is required. The upgrade is transparent and fully backward compatible with v0.4.0.

Getting Started

If you’re already using iapheaders, simply pull the latest container image to get v0.4.1:

docker pull ghcr.io/unitvectory-labs/iapheaders:v0.4.1

All environment variables and configuration options remain unchanged:

  • PORT: Server listening port (default: 8080)
  • HIDE_SIGNATURE: Toggle JWT signature display (default: false)

For new users, iapheaders helps developers inspect and debug Google Cloud Platform Identity-Aware Proxy headers by displaying authenticated user information and validating JWT tokens. See the repository for setup instructions.
