Month: 2026-01 — Catalyst Voices: Key observability and deployment improvements delivered. Implemented environment-driven logging configuration to allow log level control via LOG_LEVEL across environments, and fixed startup/entrypoint issues related to logging. These changes reduce manual configuration, improve deploy-time operability, and enhance troubleshooting capabilities.

December 2025 monthly summary focusing on delivering observability, data interoperability, and maintainability improvements across Catalyst components. Key outcomes include enabling OpenTelemetry-based telemetry for the cat-gateway, enhancing CBOR interoperability for ballot processing, and strengthening documentation and CI workflows to support faster debugging and reliable elections-related data flows.

November 2025: Focused on robustness and interoperability. Key work delivered includes a bug fix in catalyst-voices that propagates non-EventDB connection errors to the caller during FullSignedDoc insertion, and the introduction of CIDv1 support for CatalystSignedDocument in catalyst-libs, enabling IPFS-compatible content identifiers and a CID-based DocLocator. Updated tests and documentation to support the new CID workflow and ensured API compatibility where appropriate. These changes collectively improve document insertion reliability, enable future-proof content addressing, and position the project for broader ecosystem integration.

Performance summary for 2025-09 (input-output-hk/catalyst-libs). Focused feature work strengthened document governance and validation coverage.

August 2025 monthly summary for input-output-hk/catalyst-voices focusing on caching modernization and performance improvements. Delivered a consolidated caching layer across components to boost data retrieval and reliability, with a notable refactor of asset caching in Catalyst Gateway and the introduction of an Index DB session cache manager. These changes included capacity-based cache disablement, clearer logging, and updated tests, as well as in-memory caches for RBAC data and assets.

July 2025 monthly summary for input-output-hk/catalyst-voices: Achievements focused on reliability and uptime of the Catalyst gateway through targeted health improvements and middleware refinements. Key deliverables include upgrading the ScyllaDB client to 1.3.0 with refactored error handling around session disconnects, enhancing liveness detection and connection status reporting in catalyst-gateway; and excluding the /metrics endpoint from the database check middleware to avoid unnecessary DB checks during metrics scraping and to prevent transient service unavailability. These changes established clearer health signals, reduced operability risk during metrics collection, and contribute to higher gateway availability and customer-facing performance.

June 2025 monthly summary for input-output-hk/catalyst-voices. Delivered Catalyst Gateway Health Checks and Monitoring Enhancements, focusing on reliability, observability, and test stability. Readiness gating now waits for the follower to reach the tip before signaling readiness, reducing initialization races. Enhanced logging for gateway readiness and chain indexer activities, plus updated live tip metrics and sync task logging. Tests adjusted to accommodate longer health-check intervals and dependencies updated to improve stability. These changes improve deployment readiness, reduce MTTR for gateway issues, and provide clearer operational signals for incident response.

May 2025 monthly highlights for input-output-hk/catalyst-voices: Implemented database health monitoring and gateway readiness reporting, improved DB connection handling via pools, enhanced middleware error handling, and added integration tests to verify gateway readiness during outages. These changes increased service availability, improved error visibility, and strengthened resilience against dependency outages.

April 2025 performance summary: Implemented key data integrity improvements and refactors across Catalyst libraries and gateway components, delivering stricter document referencing, consistent versioning semantics, and more reliable multi-network operation. These changes reduce validation errors, improve API consistency, and lay groundwork for scalable version-aware workflows.

March 2025 monthly summary for input-output-hk/catalyst-voices: Delivered a critical backend bug fix addressing pagination in the Signed Document Index endpoint. The implementation refactors document fetching to return both the documents and the total count, adds safeguards against potential document count overflows, and expands test coverage to reproduce and validate the pagination fix. The change is associated with commit 2ea0df2e1ed72d346a76a5757e2c21ee61c6e65e (fix cat-gateway: Signed Document Index endpoint pagination bug fix, #2099).

February 2025: Implemented core security and resilience enhancements across Catalyst repos. Delivered end-to-end signing and verification for Catalyst Signed Documents using ed25519 with KID-based IDs, including CLI commands for sign/verify and integration of Catalyst ID as KID. Introduced asynchronous validation and schema enforcement for comments and proposals to improve robustness and security of the signed-doc system. Added health monitoring/liveness checks for Catalyst-Gateway through a new health utility module, using a live counter to detect panics and enforce configurable thresholds, improving service resilience. These changes strengthen data integrity, governance capabilities, and platform reliability, while expanding Rust-based implementations and CLI tooling.

Month: 2025-01 summary focusing on key accomplishments across catalyst-libs and catalyst-voices; delivered features that improve data integrity, interoperability, and tooling, with strong test coverage and CLI enhancements.

December 2024 — Focused on alignment, documentation, and release readiness across catalyst-libs and catalyst-voices. The month delivered no functional changes but set the foundation for upcoming releases through a dependency bump and expanded documentation. Highlights include a Cardano chain follower dependency update, comprehensive docs for signed document metadata in catalyst-libs, and a docs relocation/cleanup in catalyst-voices to improve consistency and reduce duplication. These changes improve maintainability, cross-repo governance, and clarity for developers integrating signed document metadata.
