May 2025 monthly summary for Dioxus (DioxusLabs/dioxus). Delivered a targeted bug fix to improve the efficiency and correctness of the Writable/Readable reactive pattern. Specifically, Writable::toggle now uses peek to avoid subscribing when Readable is Cloned, preventing unnecessary subscriptions during value inversion and reducing subscription churn. This change aligns with issue #4166 and improves runtime performance for apps relying on Writable and Readable interactions. The change is low-risk, leverages existing code paths, and enhances reliability of UI state toggling. Key commit: ab76d909e1863063048e7e80550badd837a0347b.
