What's New in Open Your Windows

1.0.1

May 4, 2026

Tightening based on early-user feedback: • More accurate rain handling — 70–90% chance forecasts no longer alone tip a clear day to "Maybe"; only the next-hour likelihood matters now, and minutely radar still triggers immediately when rain is starting. • The temperature in the reason sentence now matches the temperature in the Conditions card exactly. No more 47 vs 48 mismatches. • Widget metric chips now stay readable at all sizes — no more vertical character stacking on the medium widget.
