October 2025 highlights for duckduckgo/apple-browsers: Delivered Hang reporting and Watchdog enhancements across the product. Implemented a unified app-wide watchdog with diagnostics and EventMapper integration, UI controls to simulate hangs and timeouts, and pause/resume behavior on system sleep. Timings are aligned across platforms; max hang duration reduced to 5 seconds to match Windows; prepared for release with a remoteReleasable feature flag. Test stabilization included skipping flaky tests and disabling flaky watchdog tests to improve reliability. This work enables faster detection, triage, and cross-platform consistency, laying a strong foundation for performance and stability improvements.
