Mar 1, 2026

March 2026 monthly summary for littlehorse repo focused on security, reliability, and deployment determinism. Key features delivered include Mutual TLS (mTLS) support in the LittleHorse SDK with certificate-based configuration and accompanying tests, enabling secure client/server authentication and easier credential management. Major bugs fixed include the Docker image tagging policy improvement that disables the automatic 'latest' tag to enforce versioned deployments, reducing non-deterministic releases and production risk. CI/CD infrastructure was strengthened by upgrading GitHub Actions versions in CI workflows to enhance build stability, compatibility with newer features, and security updates. Additional impact was achieved by implementing tests to validate mTLS functionality, contributing to higher confidence in secure communications and overall deployment reliability. Business value: These changes reduce production risk through deterministic deployments, strengthen security posture with mTLS, and accelerate reliable delivery via up-to-date CI/CD tooling and improved testing coverage.

November 2025 (2025-11): Focused on stabilizing workflow Run ID handling to protect downstream processing and dashboard integrity. Reverted wfRunId utility changes to restore original behavior and adjusted wfRunIdFromList to preserve the original order of IDs, preventing misordered or duplicate workflow IDs in the application. This work reduces risk in batch processing and analytics pipelines and improves end-to-end reliability for users relying on workflow IDs.

Jul 1, 2025

In July 2025, focused on strengthening API contract consistency for NodeRun across SDKs by standardizing the protocol buffer field name from wait_threads to wait_for_threads. No new user-facing features this month; the primary work was a targeted bug fix and refactor to align with the contract across Go, Java, JavaScript, and Python SDKs. This alignment reduces cross-language integration issues and improves long-term maintainability.
