-**News**: We released the codebase v1.0.0rc3.
+**News**:
 
-Note: We are going through large refactoring to provide simpler and more unified usage of many modules.
+**v1.1.0rc0** was released in 1/9/2022:
 
-The compatibilities of models are broken due to the unification and simplification of coordinate systems. For now, most models are benchmarked with similar performance, though few models are still being benchmarked. In this version, we update some of the model checkpoints after the refactor of coordinate systems. See more details in the [Changelog](docs/en/changelog.md).
+- Unifies interfaces of all components based on [MMEngine](https://github.com/open-mmlab/mmengine) and [MMDet 3.x](https://github.com/open-mmlab/mmdetection/tree/3.x).
+- A standard data protocol defines and unifies the common keys across different datasets.
+- Faster training and testing speed with more strong baselines.
 
-In the [nuScenes 3D detection challenge](https://www.nuscenes.org/object-detection?externalData=all&mapData=all&modalities=Any) of the 5th AI Driving Olympics in NeurIPS 2020, we obtained the best PKL award and the second runner-up by multi-modality entry, and the best vision-only results.
-
-Code and models for the best vision-only method, [FCOS3D](https://arxiv.org/abs/2104.10956), have been released. Please stay tuned for [MoCa](https://arxiv.org/abs/2012.12741).
