## Recent Changes (v0.3.0)

### Advanced Pagination Features

The latest version includes significant improvements to the search pagination system:

- **Super Pagination**: New algorithm that combines JSON API and HTML scraping for comprehensive results
- **Higher Result Limits**: Get up to 100 search results (depending on query popularity)
- **Intelligent Fallbacks**: Automatically switches between different methods to maximize result gathering
- **Rate Limit Prevention**: Human-like pauses and varying user agents reduce the risk of being blocked

### Technical Notes

- **For Developers**: There is a known security audit warning about axios in development dependencies which does not affect the production build.
- **Version Warning**: If upgrading from v0.2.x, be aware that the pagination behavior has been improved significantly.
