Apr 1, 2026April 2026 (2026-04) focused on boosting reliability and enabling key capabilities across rivet. Delivered new cache and messaging features, modernized actor APIs, and enhanced Envoy integration while stabilizing cross-DC operations. These changes drive lower latency, fewer errors in cross-region calls, and set the stage for scalable workloads. Key outcomes include new cache deduplication to reduce duplicate work, queue subscriptions for UPS to enable scalable processing, actors API version 3 for richer actor interactions, a migration path for actors from V1 to V2, and a more fully fleshed-out Envoy tunnel client enabling robust networking across environments.

Mar 1, 2026March 2026: Delivered end-to-end Rivet Platform onboarding enhancements, added KV range operations (listRange, deleteRange, scan), transaction tagging, and reliability/observability improvements. Implemented protocol upgrades (TypeScript runner to v7) and wire-format alignment; introduced range-based loop history pruning and parallel checkpointing for safer, higher-performance execution. Also stabilized CI (PR actions) and updated landing pages, while expanding runtime config with explicit protocol conversions. Result: faster onboarding, safer KV interactions, and stronger platform reliability, enabling customers to scale confidently.

Jan 1, 2026January 2026 performance summary for rivet-gg/rivet: Delivered a Release Candidate 2.0.34-rc.1 with enhanced error handling across actors and runners, and refactored ActorStatusLabel for consistent error property naming. Versioning updates to 2.0.34-rc.1 were applied via multiple commits, including a patch to fix the actor status label. However, the actor and KV metrics feature was rolled back to preserve stability after evaluation, with a clear revert commit. The month closed with improved release readiness, better error-handling foundations, and disciplined change management that supports faster, safer future releases.
