Jan 1, 2025January 2025 monthly summary for latticexyz/mud. Delivered core data flow improvements, reliability enhancements, and developer tooling to accelerate indexing, testing, and deployment workflows. Key outcomes include a data-flow overhaul of the Stash module, more reliable watchLogs RPC handling, new indexer-based data access in the deploy CLI, a local-development-friendly GenerousPaymaster contract, and expanded indexer configuration and robustness improvements across protocol parsing and load-balanced RPCs. These changes reduce operational friction, improve data consistency across subscribers, and enable more flexible, scalable indexing and testing in local and CI environments. Technical highlights include improved data consistency and subscriber predictability; faster, cheaper local testing; broader deployment-time data sources; robust protocol encoding; and resilient data retrieval in distributed RPC environments.

Oct 1, 2024October 2024 monthly summary for latticexyz/mud: Focused on improving log streaming reliability and correctness within the store-sync watchLogs pipeline. Delivered two changes: 1) WatchLogs streaming reliability improvements: introduced a ping-pong keepalive mechanism and automatic reconnect to ensure a reliable, continuous log stream. 2) WatchLogs initial synchronization correctness fix: ensured initial and buffered logs are combined and sorted before emission to fix startup gaps. Business value: more stable log ingestion, improved observability, and reduced incident risk in production. Technical impact: asynchronous reconnection, keepalive, log buffering and sort-before-emit logic.
