CrossfireSync v0.0.6 was released on May 26, 2025, marking a focused maintenance update for this Java library that enables real-time Firestore synchronization across GCP regions using Pub/Sub. This release continues the project’s commitment to stability and security through comprehensive dependency updates.

What’s New

This maintenance release contains no functional changes to the core library API. Instead, v0.0.6 focuses entirely on keeping the project’s dependencies current and secure. The update spans 51 dependency upgrades, ensuring users benefit from the latest security patches and stability improvements across the entire ecosystem.

Key dependency updates include:

  • Google Cloud libraries updated to their latest versions for improved GCP integration
  • JUnit Jupiter and Mockito refreshed for continued testing excellence
  • Maven build plugins upgraded for modern build reliability
  • GitHub Actions workflows updated from v4 to v5, including the Codecov action

The library’s public API remains completely unchanged from v0.0.5. Existing integrations will continue to work without modification.

Why It Matters

Maintenance releases are critical for long-term project health and user security. By systematically updating dependencies across the board, this release:

  • Strengthens security through patches in underlying libraries
  • Improves stability with tested, stable versions of build tools and frameworks
  • Ensures future compatibility by keeping pace with ecosystem evolution

For teams relying on CrossfireSync for production Firestore synchronization between GCP regions, this release provides peace of mind. The zero breaking changes guarantee a frictionless upgrade path—simply update your Maven dependency version and continue building.

The library continues to support both SINGLE_REGION_PRIMARY mode (writes directed to one primary region with replication elsewhere) and MULTI_REGION_PRIMARY mode (multi-region writes with eventual consistency), giving architects flexibility in designing their cross-region data strategies.

Upgrade Instructions

Upgrading to v0.0.6 requires only a version change in your build configuration:

<dependency>
    <groupId>com.unitvectory</groupId>
    <artifactId>crossfiresync</artifactId>
    <version>0.0.6</version>
</dependency>

After updating, run your test suite to confirm everything operates as expected. No code modifications are necessary—the API is identical to v0.0.5.

The library requires Java 17 or higher and is available through Maven Central. Related projects like crossfiresyncrun for Cloud Run deployment and reference implementations for Firestore publisher and Pub/Sub consumer Cloud Functions remain available for teams seeking end-to-end deployment patterns.
