For 2025-09, delivered a reliability-focused enhancement in facebook/react-native by removing the releaseImageDataWhenConsumed flag and making image data release always-on via ImageResponseObserverCoordinator. This reduces feature-flag complexity, centralizes the lifecycle, and improves consistency of image data handling across apps. The change was shipped in commit 3895831c2bc83faf68223bb2a491e796d2799b24 ("ship releaseImageDataWhenConsumed (#53576)"). Overall impact includes simpler feature-flag management, more predictable memory/latency characteristics for image processing, and smoother onboarding for developers, contributing to a more robust React Native image pipeline.
