FirestoreProto2Map v0.0.2 is now available, bringing important dependency updates and documentation improvements to this Java helper library for working with Firestore Protocol Buffers in Cloud Functions.

Released on June 28, 2024, this maintenance release builds on the foundation established in v0.0.1 (April 2024) by updating critical dependencies and improving the developer experience without introducing any breaking changes.

What’s New

Dependency Updates

The most significant change in v0.0.2 is the update of the Google Cloud Firestore SDK from version 3.20.0 to 3.21.6. This spans multiple incremental updates that bring upstream bug fixes and improvements from Google’s team, ensuring your application benefits from the latest stability and security patches in the Firestore ecosystem.

Test dependencies have also been updated, including JUnit Jupiter, Mockito, and other testing utilities to their latest compatible versions.

Documentation Improvements

The README has been enhanced with:

  • Maven Central Repository badge - Quick access to artifact information
  • Javadoc badge - Direct links to API documentation
  • Usage examples - Clear Maven dependency snippets for integration
  • Confidence signal - Removal of the “under development” warning, indicating the core functionality has reached a stable state suitable for production use

Build System Refinements

Behind the scenes, CI/CD workflows and build tools have been updated to improve reliability and maintainability for future releases.

Why It Matters

This release represents a commitment to maintaining a healthy, up-to-date library even when no new features are being added. For users, this means:

Zero-friction upgrades: v0.0.2 is a drop-in replacement for v0.0.1. If you’re already using firestoreproto2map, upgrading requires only a version number change in your pom.xml file. No code modifications, no API changes, no migration headaches.

Transitive security and bug fixes: By updating the Google Cloud Firestore SDK dependency, your application indirectly receives all the improvements, performance enhancements, and bug fixes that Google has released between versions 3.20.0 and 3.21.6. Keeping dependencies current is one of the simplest ways to maintain application health.

Developer experience: With proper Maven Central badges and Javadoc links now prominently displayed in the README, new users can quickly verify the library’s legitimacy and access documentation without digging through code repositories.
