@@ -25,6 +25,8 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Quantity decimal precision** — `qtyNum` in recipe/cooking ingredient buttons and `conf` fallback display in inventory cards now limited to 1 decimal place (was showing 7+ decimal places from raw AI output, e.g. `0.25353223 conf`).
 - **"Errore" / "Error" fallback strings** — All remaining Italian hardcoded `'Errore'` fallbacks in `showToast()` calls replaced with `t('error.generic')`. Italian fallback strings removed from buttons that already used `t()`.
 - **README Italian phrases** — "La quantità è giusta (2 pz)", "🤖 Spiega", "Latte / Affettato / Panna da cucina", "Buon appetito!", "L'ho buttato" replaced with English equivalents in the README.
+- **Appliance chips translated** — `renderAppliances()` now shows translated names (e.g. "Air fryer" in EN, "Heißluftfritteuse" in DE) for all known canonical Italian appliance names via `_applianceDisplayName()` lookup. `addApplianceQuick` toast no longer hardcoded Italian. Remove-button title translated.
+- **Gemini API key not preserved on settings save** — `saveSettings()` was overwriting `s.gemini_key = ""` when the Gemini input field was empty (it is intentionally not pre-populated for security). Key is now preserved if the input is blank. `_geminiAvailable` is re-fetched from the server after every settings save so the recipe buttons reflect the real state immediately.
