databento 0.74.1

Release notes

Enhancements

• Upgraded databento-dbn to 0.52.1:
  • Added __index__ to all int-representable and char-backed Python enums, enabling
    use with int(), hex(), and as sequence indices
  • Fixed memory leak in Python bindings where every record object leaked ~64 bytes
    due to a pyo3 0.28 regression in #[pyclass(dict)] deallocation. Downgraded
    pyo3 to 0.27.2
  • Removed unnecessary dict from BidAskPair and ConsolidatedBidAskPair Python
    classes
  • Fixed Python type stubs to reflect that record_size() is a method, not a property
  • Fixed Python type stubs for record fields to indicate which fields are writable
    (e.g. publisher_id, instrument_id, price, size) and added @setter stubs
    for enum fields (e.g. action, side)
