Apr 1, 2026April 2026 performance summary for microsoft/FluidFramework: Delivered core telemetry stability and enhancements that improve monitoring, alerting, and diagnostics for load-related failures, while expanding telemetry coverage with new log levels. Implemented a robust fix to categorize ContainerClose and ContainerDispose errors as 'error' during load failures, added unit tests, and introduced new log levels to enhance telemetry granularity while preserving backward compatibility. Also introduced API surface improvements to support clearer documentation of log levels and future deprecation planning. These changes deliver tangible business value through faster incident detection, better data quality, and smoother developer/operator workflows.
