## Changelog

### v0.6.0 (20/9/2020)

#### Highlights

- Support new methods [H3DNet](https://arxiv.org/abs/2006.05682), [3DSSD](https://arxiv.org/abs/2002.10187), [CenterPoint](https://arxiv.org/abs/2006.11275).
- Support new dataset [Waymo](https://waymo.com/open/) (with PointPillars baselines) and [nuImages](https://www.nuscenes.org/nuimages) (with Mask R-CNN and Cascade Mask R-CNN baselines).
- Support Batch Inference
- Support Pytorch 1.6
- Start to publish `mmdet3d` package to PyPI since v0.5.0. You can use mmdet3d through `pip install mmdet3d`.

#### Backwards Incompatible Changes

- Support Batch Inference (#95, #103, #116): MMDetection3D v0.6.0 migrates to support batch inference based on MMDetection >= v2.4.0. This change influences all the test APIs in MMDetection3D and downstream codebases.
- Start to use collect environment function from MMCV (#113): MMDetection3D v0.6.0 migrates to use `collect_env` function in MMCV.
`get_compiler_version` and `get_compiling_cuda_version` compiled in `mmdet3d.ops.utils` are removed. Please import these two functions from `mmcv.ops`.

#### Bug Fixes
