# Changelog

## v2.1.0 - Pure-Python Stack

### Breaking Changes
- HTMX, Jinja2, Alpine.js, and Tailwind CSS frontend removed entirely
- No HTML templates, no inline HTML/CSS, no `unsafe_allow_html` anywhere in the codebase
- Frontend is a pure-Python Streamlit dashboard at `frontend/` (`streamlit run frontend/Home.py`)

### What's New
- Streamlit dashboard restored with native widgets only: Sentiment Analyzer, Batch Analytics, System Monitor
- Admin section gated behind an optional `ADMIN_PASSWORD`
- Dashboard talks to the FastAPI backend over HTTP (`API_BASE_URL`, default `http://localhost:8000`)
- README and docs updated to reflect the Python-only stack

### Notes
- API server: `uvicorn api.main:app --reload` on port 8000
- Dashboard: `streamlit run frontend/Home.py` on port 8501
- JSON API endpoints at `/predict`, `/batch`, `/status/{job_id}`, `/health`, `/info`, `/metrics`
- Swagger UI at `/docs` is preserved
- All ML model code, Celery workers, DVC/MLflow integration is unchanged
