+### What's new in 1.3.1
+
+- 🪶 **Quantized models** — *Large v3 Turbo q5_0* keeps the transcription server at ~0.7 GB RAM instead of ~1.75 GB, at the same speed (also Small q5_1, Medium q5_0, Turbo q8_0 and Large v3 q5_0)
+- 📥 **Download progress window** — progress bar, size, speed, time remaining, Cancel/Retry; progress also shows in the menu bar and Settings
+- 🔥 **Model warm-up at recording start** — if the model was paged out after a pause, it starts loading as soon as you start talking, not after you stop; the HUD tells you when a transcription is slower because the model is still loading
+
+### What's new in 1.3.0
+
+- ⚡ **Warm transcription server** — the Whisper model stays loaded in a background `whisper-server`, so each dictation is a fast local call (~0.5s) instead of reloading the 1.5–1.6 GB model on every utterance
+- 📊 **Live mic-level HUD** while recording, which warns ("No audio input?") if the microphone stays silent
+- 📖 **Custom dictionary** — an editable *Heard → Replacement* table that fixes names/jargon in the transcript and also biases recognition
+
 ### Features
 
 - 🎤 Global hotkey (⌃⌥D) to start/stop recording
+- ⚡ Fast transcription via a warm whisper-server (model stays loaded — no per-dictation reload), with automatic fallback to `whisper-cli`
+- 📊 Live mic-level meter while recording, with a "no audio input" warning
+- 📖 Custom dictionary (heard → replacement) that also biases recognition
 - 🔒 Fully offline - uses local Whisper model
-- ⚡ Automatic paste into any focused app

 Models are stored in `~/.whisper-models/`
 
+> With the warm server (1.3.0+), the selected model loads once at startup (a few seconds); after that each dictation skips the reload, so the speeds above are roughly the per-dictation transcription time.
+>
+> The server keeps the whole model in memory while it runs. If macOS pages it out after a long pause, 1.3.1+ starts loading it back as soon as you start recording, and the HUD shows *"Loading model into memory…"* if that takes a moment.
