December 2025 — aws-amplify/amplify-js: Storage cache control enhancement. Delivered S3 Cache-Control support by introducing a cacheControl option across uploadData, downloadData, and getUrl, enabling explicit caching of S3 objects to balance data freshness with performance. Implemented in a single feature commit (4189c66ac674073d330ef29ebf0df4580e4db047), reflecting strong focus on performance optimization and developer control of caching behavior. This work improves end-user experience through reduced latency and fresher data for assets served from S3.
