 ### Breaking Changes
  - Remove the `Trace` class, as it was no longer used.
  - Renamed `example_trace` to `example_tracer` and changed return type to `Optional[Tracer]`.

   - ControlModels throw a warning instead of an error in case a not-recommended model is selected.
   - The `LimitedConcurrencyClient.max_concurrency` is now capped at 10, which is its default, as the underlying `aleph_alpha_client` does not support more currently.
   - ExpandChunk now works properly if the chunk of interest is not at the beginning of a very large document. As a consequence, `MultipleChunkRetrieverQa` now works better with larger documents and should return fewer `None` answers.
