+### What's new in 1.4.1
+
+- 🎨 **Native icons instead of emoji** — the menu bar icon, recording overlay, download window, menus and Settings now use macOS SF Symbols: sharp at any size, matching light/dark menu bars, and the menu bar microphone turns red while recording
+
+### What's new in 1.4.0
+
+- 💬 **Live preview while recording** — the recording overlay shows what you're saying as you speak, using macOS's on-device dictation model (works in Hungarian too). It's a preview: the pasted text still comes from Whisper, so it can differ slightly. Toggle it in Settings.

 - 📊 Live mic-level meter while recording, with a "no audio input" warning

 - **Sound feedback**: Toggle audio feedback on/off

 ## Security
 
 - All processing is done locally - no data leaves your device
+- The live preview uses macOS's on-device dictation model (SpeechAnalyzer); it needs no extra permission beyond the microphone
 - The bundled `whisper-server` is bound to `127.0.0.1` (loopback only) and is never exposed on the network
 - Audio files are stored in private temp directory and deleted after transcription
 - Clipboard is cleared after paste (transcript doesn't remain accessible)
