Feb 1, 2025February 2025 (intel/PerfSpect): Focused on reliability, observability, and release readiness. Key enhancements include version management for 3.3.0/3.3.1, race-condition and stop-signal fixes in metrics processing, and expanded telemetry capabilities (indefinite collection, timestamps, post-processing). Notable feature work: graceful shutdown of child processes, updates to framecount, HTML report refactor, and new metrics (branch mispredict ratio). Documentation and README improvements to aid onboarding and maintainability. These changes collectively improve data accuracy, reduce partial data risk during shutdown, and accelerate decision-making with clearer instrumentation and reporting.
