Jan 1, 2026January 2026 performance-focused sprint for splice (hyperledger-labs/splice): delivered core platform stability and performance improvements via Canton upgrades to 3.4.x snapshots across tests/CI, adoption of new sequencer connection pools, and enabling async logging by default. Implemented config-driven pruning via Pulumi, added a synchronizer-id cache to reduce repeated lookups and log noise, and expanded Hyperdisk integration to boost durability and deployment efficiency. Minor deployment and observability fixes were addressed to improve reliability and operational clarity. Business impact: faster test cycles, more reliable deployments, lower log noise, and improved resource efficiency across CI and production-like environments.

Nov 1, 2025November 2025: Delivered a focused set of Canton upgrades, reliability fixes, and observability improvements for splice, driving higher throughput, better operability, and stronger security. Highlights include Canton version upgrades across 3.4.x and 0.4.x lines (up to 3.4.9) with amplification improvements; admin token enhancement adding admin claim; observability and Helm configuration improvements (clear gauges, improved API, default log levels) and load-testing configurability with extended dashboards; throughput and reliability gains (TPS cap raised to 20, ACS commitments catch-up, CometBFT timeout alignment); stability improvements (sim time fixes, test retry corrections) and release hygiene (post-0.5.1 notes, version bumps). Release-aligned changes also include key migration recovery enhancements and removal of a quickfix and a reversion of default pruning; onboarding secret rate limiting to prevent abuse.
