May 1, 2026May 2026 monthly summary for ethersphere/bee: focused on API completeness, reliability, and observable performance across the project. Delivered bootnode-aware status reporting, API spec alignment, enhanced Swarm/SOC API capabilities, and new postage/batch endpoints, complemented by telemetry improvements. Implemented a startup reliability fix to prevent proceeding when the last-synced postage block is ahead of the chain tip, with a backoff to avoid transient RPC issues. These changes improve integration confidence, reduce downtime risk, and provide richer operational visibility for capacity planning and SLA tracking.
