Fixed in PR #115. Bhavcopy download was failing due to NSE format migration on July 8, 2024. Now the library automatically handles both formats: recent dates (≥ Jul 8, 2024) use UDiff format from daily-reports API, earlier dates use BHAVDATA-FULL format. All dates should work seamlessly now. Version 0.32.0.
