 # Changelog
 
+## 2026-02-21 - 7.4.2 - fix(monitoring,remoteingress,web)
+Prune old metrics buckets periodically, clear metrics caches on shutdown, simplify edge disconnect handling, and optimize network view data updates
+
+- Call pruneOldBuckets() each minute to proactively remove stale time-series buckets in MetricsManager
+- Clear metricsCache, emailMinuteBuckets and dnsMinuteBuckets when MetricsManager stops to avoid stale state on shutdown
+- On edgeDisconnected remove the edgeStatuses entry instead of mutating an existing record (more explicit cleanup)
+- Remove unused traffic-timer variables and move requestsPerSec history updates from render() into updateNetworkData() to avoid unnecessary re-renders
+- Optimize traffic data array updates by shifting in-place then reassigning arrays to preserve Lit reactivity and reduce intermediate allocations
+
 ## 2026-02-21 - 7.4.1 - fix(dcrouter)
 replace console logging with structured logger, improve metrics logging, add terminal-ready wait in ops UI, bump dees-catalog patch
