May 2025 Towns protocol: Delivered core data-health and reliability improvements across snapshot handling, data retention, integrity, and remote sync. Implemented Snapshot Format Modernization with a new stream.enableNewSnapshotFormat flag, added an enabling script, and enriched stream updates to include full snapshots when a snapshot hash is present. Introduced Space and User Stream trimming and snapshot retention to cap miniblock growth and storage usage. Fixed critical data integrity issues (panic in ephemeral stream normalization, guarded snapshot unpacking, and duplicate media chunks handling). Enhanced Sync Reliability with client availability checks and robust fallback to alternative remotes, plus streamlined syncer initialization. These changes improve data correctness, performance, storage efficiency, and resilience of node synchronization, delivering tangible business value with lower operational risk.

In March 2025, the towns team delivered measurable business value by stabilizing and accelerating streaming workflows, removing legacy surfaces to reduce maintenance, and enhancing observability and correctness across the stream pipeline. Notable work includes integrating the StreamRegistry 'stream added' event, removing legacy media stream functions from the SDK, optimizing and testing the dynamic buffer in sync streams, and strengthening synchronization logic against races and nil responses. Observability and state-tracking were improved through Prometheus metrics on StreamCache and a new miniblock snapshot hash. API surface was simplified by removing deprecated endpoints. Overall impact: more reliable stream processing, faster iteration cycles, and clearer monitoring, enabling higher throughput with lower risk to production workloads.
