Breaking Changes

●Issue #1

Native index creation now supports nested field paths. This may affect how indices are defined if you were relying on previous implicit path handling.

Migration Steps

  1. 1
    Review index creation logic if relying on implicit path handling, as native index creation now explicitly supports nested field paths.
