Apr 1, 2025April 2025 performance summary for streamr-dev/network. The month focused on stabilizing core network functionality while preparing for the next release cycle. Key features delivered include extensive SDK refactoring and maintenance that modernized TypeScript usage, migrated utilities to test-utils, centralized contract artifacts, and environment/deploy enhancements, with release readiness for v103.0.0-rc.2. Major bugs fixed include a memory leak in DhtNode resolved by replacing direct event listeners with addManagedEventListener to ensure proper cleanup when a node leaves a stream part, and WebRTC private address probing default handling corrected by reading defaults via StreamrClient#getConfig(). Overall impact: improved runtime stability, reduced memory footprint in DhtNode operations, more reliable configuration defaults for WebRTC probing, and a stronger foundation for developer productivity and faster, cleaner releases. Technologies/skills demonstrated: TypeScript modernization (nullish coalescing), comprehensive refactoring, test-utils migration, contract artifact management, CLI and environment/deploy enhancements, and overall emphasis on maintainability, performance, and release readiness.
