24 Commits • 20 Features
Oct 1, 20252025-10 monthly summary for hyperledger-labs/splice: Security hardening, reliability, and observability enhancements delivered at scale. Highlights include moving Grafana backend to PostgreSQL for improved reliability, updating the DA Finance dashboard to include the latest round, and reducing operational noise through alerting optimizations. Infrastructure modernization advanced with Pulumi migration for SV Auth0 M2M apps and security improvements to Ledger API (default m2m audience and no-auth HMAC). This work improves data-driven decision making, reduces alert fatigue, strengthens authentication and authorization, and enables more robust deployments across Kubernetes, CI, and monitoring.

Aug 1, 2025August 2025 (2025-08) – Focused on infrastructure fidelity, CI reliability, and caching optimizations for splice. Key changes include Pulumi-based Istio gateway/loopback reimplementation aligned with updated infra code, TCP LoadBalancer separation for improved throughput, nix cache persisted to Google Cloud Storage for faster CI cycles, and migrations of CI tasks to GitHub-hosted runners. Also reorganized OpenAPI codegen under the LFDT namespace and cleaned up obsolete artifacts to streamline maintenance and releases.
