 # Changelog
 
+## 2026-03-20 - 4.13.2 - fix(remoteingress-core)
+preserve reconnected edge entries during disconnect cleanup
+
+- Guard edge removal so disconnect handlers only delete entries whose cancel token is already cancelled
+- Prevents stale TCP and QUIC disconnect paths from removing a newer connection after an edge reconnects
+
 ## 2026-03-19 - 4.13.1 - fix(remoteingress-core)
 default edge transport mode to QUIC with fallback
