AWS Lambda Runtime Interface Client for NodeJS v4.0.0

Key Changes

Core Architecture:

• Migrated to TypeScript with ESM-first environment
• Targets Node.js 22+ exclusively
• Implements two-dimensional multi-concurrency model for Lambda Managed Instance (Multiconcurrency) compatibility
• Replaced Make/shell scripts with npm-based build system

Handler & Context Updates:

• Removed callback-based handler support (promise-based only)
• Eliminated legacy context.succeed/fail/done methods
• Removed legacy callbackWaitsForEmptyEventLoop getters/setters

Developer Experience:

• Native RIE testing support with single build command
• Introduced InvokeStore package for trace ID propagation via AsyncLocalStorage

Runtime Behavior:

• No BeforeExit event loop waiting (pure runtime loop)
• Worker thread count defaults to logical CPU count
• Configurable via AWS_LAMBDA_NODEJS_WORKER_COUNT
