On December 14, 2024, we released iapheaders v0.3.0. This version is a dedicated maintenance release, focusing on reinforcing the security foundations of the project and polishing the user experience to ensure a more stable and transparent tool for inspecting GCP Identity-Aware Proxy (IAP) headers.

What’s new

While v0.3.0 doesn’t introduce sweeping new features, it brings several important refinements:

  • Security and Core Updates: We’ve bumped critical dependencies, including golang.org/x/crypto and jwx/v2, ensuring the tool leverages the latest security patches and performance improvements for JWT decoding and cryptographic operations.
  • UI Refinements: To improve maintainability and load times, we’ve moved CSS styles into a dedicated static file and added a footer to the application interface for a more complete look and feel.
  • Enhanced Documentation: The project’s README.md has been significantly upgraded. We’ve added a “Limitations” section to provide clear expectations regarding JWK caching, and included screenshots and badges to help new users get started more quickly.
  • Hardened CI/CD: Behind the scenes, we’ve optimized our GitHub Actions workflows and disabled credential persistence, further securing the build and release pipeline.

Why it matters

For developers and administrators using iapheaders to debug identity flow, stability and trust are paramount. By updating the underlying cryptographic libraries and hardening the CI/CD pipeline, we ensure that the tool remains a secure and reliable part of your toolkit.

Furthermore, the improvements to the documentation and UI reflect our commitment to transparency. By clearly outlining the current limitations and providing visual guides, we reduce the friction for new users and provide existing users with a more professional experience.

Getting started with v0.3.0

Upgrading to the latest version is seamless. Since iapheaders is distributed as a Docker image, you can simply pull the latest version from GitHub Packages:

ghcr.io/unitvectory-labs/iapheaders

Whether you are troubleshooting a complex IAP configuration or simply verifying JWT claims, v0.3.0 provides a polished and secure environment to get the job done.
