A Focused Maintenance Release

On October 21, 2025, we released authzjwtbearerinjector v0.3.4—a maintenance-focused update that keeps your JWT bearer token injection infrastructure secure and up-to-date. While this release doesn’t introduce new features, it represents important work beneath the surface: modernizing core dependencies, upgrading to Go 1.25.3, and ensuring our CI/CD pipelines use the latest security tooling.

For users running authzjwtbearerinjector in production, this is a straightforward drop-in upgrade that brings upstream security fixes from gRPC and Envoy control-plane libraries without requiring any configuration changes.

What’s New

Core Dependency Updates

This release bundles significant updates to the project’s foundational libraries:

  • gRPC Library: Updated from v1.72.0 to v1.76.0—tracking through seven incremental versions to stay current with upstream bug fixes and security patches
  • Envoy Control Plane: Bumped from v1.32.4 to v1.35.0, bringing the latest Envoy Proxy API support
  • Go Language: Upgraded from Go 1.24.3 to Go 1.25.3 through six progressive version updates

These dependency updates also bring along transitive improvements across the protobuf, network, and system library stacks.

CI/CD Modernization

Our build infrastructure received a comprehensive update, with all GitHub Actions workflows migrated to their latest major versions:

Action Updated To
actions/checkout v5
actions/setup-go v6
github/codeql-action v4
actions/attest-build-provenance v3

This modernization improves build security and ensures our release artifacts are generated with the latest tooling best practices.

Small But Polished

Minor improvements include a corrected code comment (we fixed “betwen” to “between”) and a new Go Report Card badge on the README for quick visibility into code quality metrics.

Why It Matters

Maintenance releases like v0.3.4 might not make headlines, but they’re essential for keeping production systems secure and stable. Here’s why this update is worth your attention:

Security Posture: Every dependency update potentially includes security patches from upstream projects. The gRPC library alone went through seven version increments—each one addressing issues discovered and fixed by the broader community. By releasing these updates promptly, we help ensure that authzjwtbearerinjector deployments benefit from upstream security improvements as soon as they’re available.

Upstream Compatibility: Staying current with Go versions and Envoy control-plane libraries ensures compatibility with the latest features and bug fixes in those ecosystems. This is particularly important for a project like authzjwtbearerinjector that sits at the intersection of gRPC authorization and Envoy Proxy—it needs to speak the latest protocols reliably.

Build Infrastructure Health: Updating CI/CD actions to their latest major versions isn’t just about convenience; it’s about security. Modern GitHub Actions incorporate improvements in how they handle secrets, artifact provenance, and code scanning. The move to CodeQL v4, for example, brings enhanced static analysis capabilities that catch potential issues before they reach your deployment.

Automated Dependency Management at Work: The heavy reliance on Dependabot-generated pull requests (the majority of the 19 commits in this release) demonstrates a mature approach to dependency management. Automated tools handle the routine updates, allowing human maintainers to focus on reviewing and validating changes rather than manually tracking every version bump.

Upgrading to v0.3.4

Docker Users

Upgrading is simple—no configuration changes required:

# Pull the new image
docker pull ghcr.io/unitvectory-labs/authzjwtbearerinjector:v0.3.4

# Stop your existing container and start with the updated tag
# Your existing configuration files remain valid

Building from Source

If you build authzjwtbearerinjector from source, ensure you have Go 1.25.3 or later installed:

git clone https://github.com/UnitVectorY-Labs/authzjwtbearerinjector.git
cd authzjwtbearerinjector
go build -o authzjwtbearerinjector ./cmd/authzjwtbearerinjector

Compatibility Guarantee

This release is fully backward-compatible with v0.3.3:

  • No breaking changes to the gRPC ExtAuthz interface
  • No configuration schema changes—your existing YAML configs work as-is
  • No deprecations to worry about

You can upgrade with confidence, knowing your JWT bearer token injection workflows will continue functioning without modification.

Looking Ahead

v0.3.4 exemplifies the ongoing maintenance philosophy that keeps authzjwtbearerinjector reliable in production: dependencies stay current through automated tooling, security patches flow through promptly, and the team remains committed to a smooth upgrade experience for users.

We’re grateful for the community’s continued use of authzjwtbearerinjector as their JWT bearer token injection solution for Envoy Proxy-based authorization flows. If you’re running this in production or have feedback on the project, we’d love to hear from you via GitHub Issues.
