## Summary

Last9 changelog introducing several platform improvements: aggregate log queries now surface the top 5 contributing raw log lines beneath the chart, eliminating the need to manually strip aggregate steps. Traces gain a 'Create Metric' button for non-timeslice aggregations. Alert rule timelines now support drag-to-zoom. Mobile RUM custom events now emit OTLP logs for parity with browser RUM. Kubernetes Discover pages include ConfigMap/HPA subjects and cluster name breadcrumbs. Several bug fixes address alerting silent failures, Slack log preview timing offsets, dashboard rendering issues, and Apdex empty states.
