 - 🔴 Improved the performance of the `TimeSeries.map()` method for functions that take two arguments. The mapping is now applied on the entire time index and values array which requires users to reshape the time index explicitly within the function. See more information in the `TimeSeries.map()` method documentation. [#2911](https://github.com/unit8co/darts/pull/2911) by [Jakub Chłapek](https://github.com/jakubchlapek)
 
+- Improved the `save`/`load` methods for `TorchForecastingModel` to support `os.PathLike` objects as file path. [#2947](https://github.com/unit8co/darts/pull/2947) by [Timon Erhart](https://github.com/timonerhart)
