 ## Unreleased
 
+## 0.3.2.16 - 2026-07-15
+- Host: normalize the random `Id`, item path, and menu path generated by
+  Ayatana StatusNotifierItem implementations when building logical duplicate
+  keys. Multiple instances of the same application now collapse to one tray
+  item even when each instance advertises a different generated identity.
+- Add regression coverage for generated Ayatana identities while preserving
+  distinct identities for ordinary StatusNotifierItems.
+
 ## 0.3.2.15 - 2026-07-02
 - Bound every DBus call made during host and watcher startup with a timeout so
   a single unresponsive item (a process that owns its `StatusNotifierItem` bus
