Breaking Changes

●Issue #1

Native index creation now supports nested field paths. This may change how index paths are specified if you were relying on previous implicit behavior for nested fields.

Migration Steps

  1. 1
    Review index creation logic if you rely on implicit handling of nested fields.
  2. 2
    If you were using invalid namespace modes in Python, update your code to handle the new `ValueError`.

Release Summary

This release introduces significant new features across Python and Node.js, including enhanced namespace management, support for nested field paths in indexing, and various bug fixes related to error handling and data consistency.
