 ## Changelog
 
+### v2.8.0 (04/01/2021)
+
+#### Highlights
+
+- Support new methods: [Cascade RPN](https://arxiv.org/abs/1909.06720), [TridentNet](https://arxiv.org/abs/1901.01892)
+
+#### New Features
+
+- Support [Cascade RPN](https://arxiv.org/abs/1909.06720) (#1900)
+- Support [TridentNet](https://arxiv.org/abs/1901.01892) (#3313)
+
+#### Bug Fixes
+
+- Fix bug of show result in async_benchmark (#4367)
+- Fix scale factor in MaskTestMixin (#4366)
+- Fix but when returning indices in `multiclass_nms` (#4362)
+- Fix bug of empirical attention in resnext backbone error (#4300)
+- Fix bug of `img_norm_cfg` in FCOS-HRNet models with updated performance and models (#4250)
+- Fix invalid checkpoint and log in Mask R-CNN models on Cityscapes dataset (#4287)
+- Fix bug in distributed sampler when dataset is too small (#4257)
