+# Release Notes: v2.3.3
+
+**Date:** 16. maj 2026
+
+## New Features
+
+### Telefoni Status Banner
+A new status banner was added to `app/modules/telefoni/templates/log.html` to show explicit load/error/ready states:
+
+- **`telefoni_status == "error"`** → "Telefoni: Error" with "Failed to load telefoni data."
+- **`telefoni_status == "loading"`** → "Telefoni: Loading..." with "Fetching telefoni data."
+- **`telefoni_status == "ready"`** → "Telefoni: Ready" with "Telefoni data loaded successfully."
+- **default (no status)** → "Telefoni: No data" with a stronger fallback message: "Telefoni is not available. Try again later or check the network."
+
+This improves visibility of telefoni data availability and provides clearer error messages.
