Breaking Changes

●Issue #1

The internal type for optional parameters has changed from 'NotGiven' to 'Omit'. This may break code that explicitly imports or performs type-checking against the 'NotGiven' sentinel for these specific parameters.

Migration Steps

  1. 1
    Update any type hints or logic that relies on the 'NotGiven' type for optional parameters to accommodate the 'Omit' type.

Release Summary

This release introduces the reasoning_text field to the API and updates internal type handling for optional parameters from NotGiven to Omit.
