 # Changelog
 
+## 0.7.17 - 2026-06-16
+- WebSocket-Eventpfad ist schneller: irrelevante HA-State-Changes werden vor
+  dem teuren State-Cache-Listenbau verworfen.
+- WebSocket nutzt Keepalive und reconnectet nach Abbrüchen nach 1s statt 5s.
+
 ## 0.7.16 - 2026-06-16
 - Beobachtete Aktoren werden in der Übersicht nach Raum oder Typ gruppiert und
   mit Friendly Name angezeigt.
