v2.4.0

What's Changed

Fractional Shares Support

We’ve added full native support for fractional shares across all snapshot (v2 & v3), aggregate, and trades endpoints. New fields (fractional_volume, fractional_accumulated_volume, and fractional_size) preserve exact decimal precision (returned as strings) while keeping the original volume/size fields unchanged for full backward compatibility. This applies to EquityAgg (WebSocket), UniversalSnapshot, and v2 TickerSnapshot.

New SEC Filings Endpoints (beta)

We’ve added complete coverage for the new /stocks/filings/vX/* family of beta endpoints.

• list_stocks_filings_index() - master index of all SEC filings
• list_stocks_filings_10k_sections() - raw text sections from 10-K/10-Q filings (business, risk_factors, etc.)
• list_stocks_filings_8k_text() - parsed 8-K filings with item-level text
• list_stocks_filings_risk_factors() - categorized risk factors (with supporting text)
• list_stocks_taxonomies_risk_factors() - risk factor taxonomy/categories

Check the docs for usage examples.
