 **Fixed**
 - Fixed a bug when performing optimized historical forecasts with `stride=1` using a `RegressionModel` with `output_chunk_shift>=1` and `output_chunk_length=1`, where the forecast time index was not properly shifted. [#2634](https://github.com/unit8co/darts/pull/2634) by [Mattias De Charleroy](https://github.com/MattiasDC).
+- Fixed the `ShapExplainer` `summary_plot` title where Horizon does not include `output_chunk_shift`. [#2647](https://github.com/unit8co/darts/pull/2647) by [He Weilin](https://github.com/cnhwl).
