 # Changelog for status-notifier-item
 
+## 0.3.2.1 - 2026-02-09
+- Add name-owner resolution fallback for signal sender identification, fixing
+  noisy errors when items register under well-known bus names.
+- Downgrade "Failed to identify sender" log from ERROR to DEBUG when the item
+  simply does not implement the getId method.
+- Downgrade "Property update failures" log from ERROR to DEBUG when the failures
+  are InvalidArgs (item does not support optional properties like OverlayIcon).
+
 ## 0.3.2.0 - 2026-02-05
 - Report full `bus/path` identifiers for non-default SNI object paths so hosts
   can resolve Ayatana items reliably.
