Month: 2025-10 — Focused on stability and correctness improvements in AndroidX RecyclerView. No new user-facing features this month; major work fixed an unbalanced tracing issue to prevent misinterpretation of profiling data and to maintain tracing correctness. The fix introduces a traceStarted flag in GapWorker.prefetchPositionWithDeadline to ensure Trace.endSection occurs only after Trace.beginSection. Commit: f933be1fa38c4888c47c461ef5816b109cf5da41. This work improves tracing accuracy, reduces perf dashboard noise, and strengthens reliability of prefetching logic.
