## 🚀 What's New

### User-Aware Agent Framework

- Identity flows through every layer — User context automatically available in tools, SQL queries, and audit logs
- Row-level security — Queries filtered based on user permissions
- Group-based access control — Fine-grained tool access by user groups
- Audit logging — Track every query per user for compliance

### Modern Web Interface

- Pre-built <vanna-chat> component — Drop into any webpage (React, Vue, or HTML)
- Streaming responses — Real-time tables, charts, and progress updates via SSE
- Framework-agnostic — Works with your existing auth (cookies, JWTs, OAuth)
- Customizable themes — Light/dark modes, responsive design

### Production-Ready Architecture

- FastAPI/Flask servers included — Production backends out of the box
- Modular tool system — Extend with custom Tool classes
- Lifecycle hooks — Quota checking, logging, content filtering
- Observability built-in — Tracing and metrics integration
- LLM agnostic — OpenAI, Anthropic, Ollama, Azure, Gemini, Bedrock, Mistral, and more

### Rich Streaming Components

Instead of plain text responses, get:
- Interactive data tables
- Plotly visualizations
- SQL code blocks (admin-only by default)
- Natural language summaries
- Progress indicators
