Apr 1, 2026April 2026 focused on solidifying foundational XR signaling, stabilizing ARCore rendering, and aligning runtime loading with OpenXR priorities. Delivered a foundational Jetpack XR Scene Signals framework with a type-safe configuration model and a ConversationState, and migrated away from arcore-projected in favor of OpenXR-first runtime loading. Implemented rendering fixes and coordinate transforms improvements to increase stability and performance. These workstreams collectively improve end-user stability, enable richer scene-level signaling for developers, and position the platform for broader hardware and OpenXR adoption.

Oct 1, 2025October 2025 was focused on delivering performance improvements, code modernization, and runtime flexibility for XR workflows in the androidx/androidx repo. Key features delivered include naming consistency improvements in XR SceneCore, asynchronous asset loading enhancements for faster render times, and a Kotlin-based migration of critical Impress API implementations. A refactor of SpatialSceneRuntime enables rootSceneNode/taskWindowLeashNode injection to support chimeric apps and AOSP drops, while ongoing documentation fixes improve repository clarity. These efforts collectively reduce build and load times, improve maintainability, and enable safer, faster delivery of XR features to downstream apps.
