March 2026 monthly summary capturing cross-repo progress in Windows platform ops and CI configuration. Key features include Windows hardware compatibility and test environment readiness in ronin_puppet, Xperf profiling framework with access control and scheduled task management, and Windows 11 worker pools in fxci-config. Major bug fix focused on APPX package preservation for reference workers and stabilization of service management. These efforts collectively improve reliability, security, and performance diagnostics, while enabling more flexible and safer CI/CD workflows.

February 2026: Delivered measurable improvements in performance debugging and platform hygiene across fxci-config and ronin_puppet. Key outcomes include a Windows 11 Experimental Worker Pool enabling faster diagnostics and better resource utilization for RELOPS-2176; Windows support deprecation in the main branch to simplify maintenance; removal of AppX packages with related services, coupled with Marlin reporting integration to improve hardware observability; and a fix for timezone validation in windowstime to provide clearer errors and safer configurations. Collectively, these efforts reduce maintenance burden, accelerate troubleshooting, and improve visibility into hardware and time-based configurations.

Month 2025-12 performance summary: Stabilized fxci-config deployment by reverting the Windows 11 ARM64 ARM template changes. This focused cleanup preserved proven configurations, minimized deployment risk, and maintained compatibility with existing Windows ARM64 targets. All related CI checks passed after the revert, ensuring reliable production deployments.

March 2025: Focused on expanding testing infrastructure in fxci-config by adding a dedicated Windows 11 hardware worker entry to support RELOPS-1213 testing. The change was implemented in the mozilla-releng/fxci-config repository via a single commit that updates clients.yml and documents the testing workflow. This work enhances Windows 11 testing reliability and speeds up validation cycles for related features.

February 2025 monthly summary for mozilla-releng/fxci-config: Delivered Windows 10 64-bit hardware support in CI/CD, enabling provisioning and management of Windows 10 64-bit hardware workers and CI/CD task creation for these targets. Implemented queue:create-task support for win10-64-* hardware to streamline automated task orchestration. This work, anchored by commits ae7ad8628b235d57e3ea2f718fa2000bced063f3 and 5231d83ea065d3f4f17760564d3eb38831403a49 (RelOps 1269), expands hardware coverage and testing.
