# Release v0.3.0

## ✨ New Features

### OpenAI Streaming Output Support

Finally here! Commit message generation now supports **real-time streaming output**, similar to ChatGPT's typing effect.

**Effect**: No more staring at a spinner - watch the text appear character by character.

**Configuration**: Enabled by default, can be disabled in config:

```toml
[ui]
streaming = true  # Enabled by default
```

**Support Status**:

| Provider | Streaming Support |
|----------|-------------------|
| OpenAI / Compatible API | ✅ Full support |
| Claude | ⏳ Fallback to Spinner |
| Ollama | ⏳ Fallback to Spinner |

> Providers that don't support streaming will automatically fall back to spinner mode, no manual configuration needed.

**Technical Implementation**:

- New SSE (Server-Sent Events) parsing module
- `LLMProvider` trait adds `supports_streaming()` and `generate_commit_message_streaming()` methods
- Async stream processing, real-time rendering to terminal

## 🎨 UI Improvements

### Colored Feedback Prompt

`Retry with feedback` option now shows colored prompt text, more clearly guiding user input.

### Simplified Option Description

Retry option simplified from "Retry with feedback - Regenerate with instructions" to "Retry with feedback - Add instructions", more concise.

## 📦 Dependency Changes

- Added `bytes = "1.10"` - Streaming response byte handling
- Added `futures = "0.3"` - Async stream processing
- `reqwest` adds `stream` feature

## Configuration Changes

New `[ui]` configuration option:

```toml
[ui]
streaming = true  # Enable streaming output (default true)
```

## Upgrade Notes

Upgrading from v0.2.1 requires **no action**, fully backward compatible.

Streaming output is enabled by default. If you prefer the spinner wait style, set `streaming = false`.
