September 2025 monthly summary for strands-agents/sdk-python focused on enhancing async reliability and performance. Implemented a non-blocking retry delay mechanism by replacing time.sleep with asyncio.sleep, preventing event loop blocking and enabling other asynchronous tasks to run during backoff periods. Updated tests to mock asyncio.sleep to validate non-blocking behavior without introducing flakiness. The change reduces retry-induced latency and improves responsiveness under transient failures, aligning with our async-first design goals and improving overall throughput for clients relying on strands agents.

January 2025 performance summary for the AWS Toolkit teams (VSCode and JetBrains). Focused on expanding build-tool awareness in repository archiving, stabilizing cross-OS packaging, and improving performance for auto-build workflows. Resulted in more reliable archives, improved build-tool analysis, and faster, more consistent releases across platforms.
