Unreleased

1.1.0 - 2026-08-09

Added

Changed

  • Require Elixir 1.13 or later.

Fixed

  • Accept an atom as the path in get_at/2.
  • Correct the documentation examples and run them as doctests.
  • Correct the delete_at/3 documentation on unpersisted items.
  • Raise EctoNestedChangeset.NotLoadedError in append_at/3, prepend_at/3 and insert_at/3 for a relation that is not preloaded at any path depth, not only at the first segment.
  • Raise EctoNestedChangeset.NotLoadedError in update_at/3, which passed the Ecto.Association.NotLoaded struct to the update function instead.
  • Return nil from get_at/2 for a relation of a persisted struct that is not preloaded, instead of raising or returning an Ecto.Association.NotLoaded struct.
  • Raise an ArgumentError naming the offending path segment and its position for an empty or malformed path, instead of a FunctionClauseError on a private function.
