0.24.0 - 2023-11-23

This release adds support for DBN v2 as well as Python v3.12.

DBN v2 delivers improvements to the Metadata header symbology, new stype_in and stype_out fields for SymbolMappingMsg, and extends the symbol field length for SymbolMappingMsg and InstrumentDefMsg. The entire change notes are available here. Users who wish to convert DBN v1 files to v2 can use the dbn-cli tool available in the databento-dbn crate. On a future date, the Databento live and historical APIs will stop serving DBN v1.

This release of databento-python is fully compatible with both DBN v1 and v2, so this upgrade should be seamless for most users.

In some cases, DBN v1 records will be converted to their v2 counterparts:

• When iterating a DBNStore and with DBNStore.replay
• When iterating a Live client and records dispatched to callbacks

Breaking Changes

• DBNStore iteration and DBNStore.replay will upgrade DBN version 1 messages to version 2
• Live client iteration and callbacks upgrade DBN version 1 messages to version 2
• Moved DBNRecord, RecordCallback, and ExceptionCallback types to them databento.common.types module
• Moved AUTH_TIMEOUT_SECONDS and CONNECT_TIMEOUT_SECONDS constants from the databento.live module to databento.live.session
