- Added a `--torch-device` commandline option to `mlagents-learn`, which sets the default
[`torch.device`](https://pytorch.org/docs/stable/tensor_attributes.html#torch.torch.device) used for training. (#4888)
- The `--cpu` commandline option had no effect and was removed. Use `--torch-device=cpu` to force CPU training. (#4888)
- The `mlagents_env` API has changed, `BehaviorSpec` now has a `observation_specs` property containing a list of `ObservationSpec`.

- The Parameter Randomization feature has been refactored to enable sampling of new parameters per episode to improve robustness. The
