0.52.1

Release notes

Enhancements

• Added __index__ to all int-representable and char-backed Python enums, enabling
  use with int(), hex(), and as sequence indices

Bug fixes

• 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)
