February 2026 (repo: mozilla-releng/fxci-config): Implemented a dedicated Security Update Pinning Cron Hook to isolate HSTS/HPKP updates from other periodic tasks and enable manual triggering for security-related pinning operations. This change improves security operations, reduces risk of unintended updates, and provides greater control over critical pinning workflows. Key commit: 96156024a371b23cb259ed0c39ae5ddc42545733 (Bug 1810856 - Add cron hooks for pinning updates (#843)).

November 2025 monthly summary for mozilla/bigquery-etl focused on expanding telemetry data coverage and delivering stable analytics for Windows 11 versions. All work this month was centered on feature delivery with no major bug fixes reported in the provided data.

August 2025 — Focused on stabilizing test resource handling for square/okhttp to ensure reliable test discovery after directory restructuring. No new features delivered this month; a targeted bug fix was implemented to PublicSuffixListGenerator resource path to align with the current test layout, improving CI stability and test reliability. Impact: Reduced flaky test failures, smoother CI runs, and easier maintenance of the test suite.

Summary for 2025-07 (mozilla/gecko-dev): Delivered stability and maintainability gains through targeted dependency upgrades, UI stability enhancements, and compiler hygiene improvements. Upgraded AndroidX Compose BOM to 2025.06.01 and Kotlin to 2.2.0, with suppressions to address known screen width/height configurations and swipe-to-dismiss issues, resulting in smoother UI and improved performance. Fixed a compiler warning by updating annotation syntax to the @param: target to ensure cross-component compatibility. These changes reduce runtime issues, improve user experience, and lay groundwork for future optimizations and ecosystem alignment.

Month: 2025-06 Summary: In June, delivered a targeted dependency upgrade in mozilla/gecko-dev to enhance stability and long-term maintenance.
