| #### New Features | |
| - Support [ConvNeXt](https://arxiv.org/abs/2201.03545) (#7281) | |
| - Support [DDOD](https://arxiv.org/abs/2107.02963) (#7279) | |
| - Support [SOLOv2](https://arxiv.org/abs/2003.10152) (#7441) | |
| - Support [Mask2Former](https://arxiv.org/abs/2112.01527) for instance segmentation (#7571, #8032) | |
| #### Bug Fixes | |
| - Enable YOLOX training on different devices (#7912) | |
| - Fix the log plot error when evaluation with `interval != 1` (#7784) | |
| - Fix RuntimeError of HTC (#8083) | |
| #### Improvements | |
| - Support dedicated `WandbLogger` hook (#7459) | |
| Users can set | |
| ```python | |
| cfg.log_config.hooks = [ | |
| dict(type='MMDetWandbHook', | |
| init_kwargs={'project': 'MMDetection-tutorial'}, | |
| interval=10, | |
| log_checkpoint=True, | |
| log_checkpoint_metadata=True, | |
| num_eval_images=10)] | |
| ``` | |
| in the config to use `MMDetWandbHook`. Example can be found in this [colab tutorial](https://colab.research.google.com/drive/1RCSXHZwDZvakFh3eo9RuNrJbCGqD0dru?usp=sharing#scrollTo=WTEdPDRaBz2C) | |
| - Add `AvoidOOM` to avoid OOM (#7434, #8091) | |
| Try to use `AvoidCUDAOOM` to avoid GPU out of memory. It will first retry after calling `torch.cuda.empty_cache()`. If it still fails, it will then retry by converting the type of inputs to FP16 format. If it still fails, it will try to copy inputs from GPUs to CPUs to continue computing. Try AvoidOOM in code to make the code continue to run when GPU memory runs out: | |
| ```python | |
| from mmdet.utils import AvoidCUDAOOM | |
| output = AvoidCUDAOOM.retry_if_cuda_oom(some_function)(input1, input2) | |
| ``` | |
| Users can also try `AvoidCUDAOOM` as a decorator to make the code continue to run when GPU memory runs out: | |
| ```python | |
| from mmdet.utils import AvoidCUDAOOM | |
| @AvoidCUDAOOM.retry_if_cuda_oom | |
| def function(*args, **kwargs): | |
| ... | |
| return xxx | |
| ``` | |

| - Speedup the Video Inference by Accelerating data-loading Stage (#7832) | |
| - Support replacing the `${key}` with the value of `cfg.key` (#7492) | |
| - Accelerate result analysis in `analyze_result.py`. The evaluation time is speedup by 10 ~ 15 times and only tasks 10 ~ 15 minutes now. (#7891) | |
| - Support to set `block_dilations` in `DilatedEncoder` (#7812) | |
| - Support panoptic segmentation result analysis (#7922) | |
| - Release DyHead with Swin-Large backbone (#7733) | |
| - Documentations updating and adding | |
| - Fix wrong default type of `act_cfg` in `SwinTransformer` (#7794) | |
| - Fix text errors in the tutorials (#7959) | |
| - Rewrite the [installation guide](docs/en/get_started.md) (#7897) | |
| - [Useful hooks](docs/en/tutorials/useful_hooks.md) (#7810) | |
| - Fix heading anchor in documentation (#8006) | |

| ### v2.24.0 (26/4/2022) | |
| #### Highlights | |
| - Support [Simple Copy-Paste is a Strong Data Augmentation Method for Instance Segmentation](https://arxiv.org/abs/2012.07177) | |
| - Support automatically scaling LR according to GPU number and samples per GPU | |
| - Support Class Aware Sampler that improves performance on OpenImages Dataset | |
| #### New Features | |
| - Support [Simple Copy-Paste is a Strong Data Augmentation Method for Instance Segmentation](https://arxiv.org/abs/2012.07177), see [example configs](configs/simple_copy_paste/mask_rcnn_r50_fpn_syncbn-all_rpn-2conv_ssj_scp_32x2_270k_coco.py) (#7501) | |
| - Support Class Aware Sampler, users can set | |
| ```python | |
| data=dict(train_dataloader=dict(class_aware_sampler=dict(num_sample_class=1)))) | |
| ``` | |
| in the config to use `ClassAwareSampler`. Examples can be found in [the configs of OpenImages Dataset](https://github.com/open-mmlab/mmdetection/tree/master/configs/openimages/faster_rcnn_r50_fpn_32x2_cas_1x_openimages.py). (#7436) | |
| - Support automatically scaling LR according to GPU number and samples per GPU. (#7482) | |
| In each config, there is a corresponding config of auto-scaling LR as below, | |
| ```python | |
| auto_scale_lr = dict(enable=True, base_batch_size=N) | |
| ``` | |
| where `N` is the batch size used for the current learning rate in the config (also equals to `samples_per_gpu` * gpu number to train this config). | |
| By default, we set `enable=False` so that the original usages will not be affected. Users can set `enable=True` in each config or add `--auto-scale-lr` after the command line to enable this feature and should check the correctness of `base_batch_size` in customized configs. | |
| - Support setting dataloader arguments in config and add functions to handle config compatibility. (#7668) | |
| The comparison between the old and new usages is as below. | |

| - Stable support of exporting models to ONNX with batched images and dynamic shape (#5039) | |
| #### Backwards Incompatible Changes | |
| MMDetection is going through big refactoring for more general and convenient usages during the releases from v2.12.0 to v2.15.0 (maybe longer). | |
| In v2.12.0 MMDetection inevitably brings some BC-breakings, including the MMCV dependency, model initialization, model registry, and mask AP evaluation. | |
| - MMCV version. MMDetection v2.12.0 relies on the newest features in MMCV 1.3.3, including `BaseModule` for unified parameter initialization, model registry, and the CUDA operator `MultiScaleDeformableAttn` for [Deformable DETR](https://arxiv.org/abs/2010.04159). Note that MMCV 1.3.2 already contains all the features used by MMDet but has known issues. Therefore, we recommend users skip MMCV v1.3.2 and use v1.3.3, though v1.3.2 might work for most cases. | |
| - Unified model initialization (#4750). To unify the parameter initialization in OpenMMLab projects, MMCV supports `BaseModule` that accepts `init_cfg` to allow the modules' parameters initialized in a flexible and unified manner. Now the users need to explicitly call `model.init_weights()` in the training script to initialize the model (as in [here](https://github.com/open-mmlab/mmdetection/blob/master/tools/train.py#L162), previously this was handled by the detector. The models in MMDetection have been re-benchmarked to ensure accuracy based on PR #4750. __The downstream projects should update their code accordingly to use MMDetection v2.12.0__. | |
| - Unified model registry (#5059). To easily use backbones implemented in other OpenMMLab projects, MMDetection migrates to inherit the model registry created in MMCV (#760). In this way, as long as the backbone is supported in an OpenMMLab project and that project also uses the registry in MMCV, users can use that backbone in MMDetection by simply modifying the config without copying the code of that backbone into MMDetection. | |
| - Mask AP evaluation (#4898). Previous versions calculate the areas of masks through the bounding boxes when calculating the mask AP of small, medium, and large instances. To indeed use the areas of masks, we pop the key `bbox` during mask AP calculation. This change does not affect the overall mask AP evaluation and aligns the mask AP of similar models in other projects like Detectron2. | |

| #### Backwards Incompatible Changes | |
| __FP16 related methods are imported from mmcv instead of mmdet. (#3766, #3822)__ | |
| Mixed precision training utils in `mmdet.core.fp16` are moved to `mmcv.runner`, including `force_fp32`, `auto_fp16`, `wrap_fp16_model`, and `Fp16OptimizerHook`. A deprecation warning will be raised if users attempt to import those methods from `mmdet.core.fp16`, and will be finally removed in V2.10.0. | |
| __\[0, N-1\] represents foreground classes and N indicates background classes for all models. (#3221)__ | |
| Before v2.5.0, the background label for RPN is 0, and N for other heads. Now the behavior is consistent for all models. Thus `self.background_labels` in `dense_heads` is removed and all heads use `self.num_classes` to indicate the class index of background labels. | |
| This change has no effect on the pre-trained models in the v2.x model zoo, but will affect the training of all models with RPN heads. Two-stage detectors whose RPN head uses softmax will be affected because the order of categories is changed. | |
| **Only call `get_subset_by_classes` when `test_mode=True` and `self.filter_empty_gt=True` (#3695)** | |
| Function `get_subset_by_classes` in dataset is refactored and only filters out images when `test_mode=True` and `self.filter_empty_gt=True`. | |
| In the original implementation, `get_subset_by_classes` is not related to the flag `self.filter_empty_gt` and will only be called when the classes is set during initialization no matter `test_mode` is `True` or `False`. This brings ambiguous behavior and potential bugs in many cases. After v2.5.0, if `filter_empty_gt=False`, no matter whether the classes are specified in a dataset, the dataset will use all the images in the annotations. If `filter_empty_gt=True` and `test_mode=True`, no matter whether the classes are specified, the dataset will call \`\`get_subset_by_classes\` to check the images and filter out images containing no GT boxes. Therefore, the users should be responsible for the data filtering/cleaning process for the test dataset. | |

| __Backwards Incompatible Changes__ | |
| - Support Batch Inference (#3564, #3686, #3705): Since v2.4.0, MMDetection could inference model with multiple images in a single GPU. | |
| This change influences all the test APIs in MMDetection and downstream codebases. To help the users migrate their code, we use `replace_ImageToTensor` (#3686) to convert legacy test data pipelines during dataset initialization. | |
| - Support RandomFlip with horizontal/vertical/diagonal direction (#3608): Since v2.4.0, MMDetection supports horizontal/vertical/diagonal flip in the data augmentation. This influences bounding box, mask, and image transformations in data augmentation process and the process that will map those data back to the original format. | |
| - Migrate to use `mmlvis` and `mmpycocotools` for COCO and LVIS dataset (#3727). The APIs are fully compatible with the original `lvis` and `pycocotools`. Users need to uninstall the existing pycocotools and lvis packages in their environment first and install `mmlvis` & `mmpycocotools`. | |
