 ## Major Features and Improvements
 
-### TODO
+### Ascend 910 Training and Inference Framework
+* New models
+    * DeepFM: a factorization-machine based neural network for CTR prediction on Criteo dataset.
+    * DeepLabV3: significantly improves over our previous DeepLab versions without DenseCRF post-processing and attains comparable performance with other state-of-art models on the PASCAL VOC 2007 semantic image segmentation benchmark.
+    * Faster-RCNN: towards real-time object detection with region proposal networks on COCO 2017 dataset.
+    * GoogLeNet: a deep convolutional neural network architecture codenamed Inception V1 for classification and detection on CIFAR-10 dataset.
+    * Wide&Deep: jointly trained wide linear models and deep neural networks for recommender systems on Criteo dataset.
+* Frontend and User Interface
+    * Complete numpy advanced indexing method. Supports value and assignment through tensor index.
+    * Some optimizers support separating parameter groups. Different parameter groups can set different `learning_rate` and `weight_decay`.
+    * Support setting submodule's logging level independently, e.g. you can set logging level of module `A` to warning and set logging level of module `B` to info.
+    * Support weights to be compiled according to shape to solve the problem of large memory overhead.
+    * Add some operators implement and grammar support in pynative mode. To be consistent with graph mode.
+    * User interfaces change log
+      * Learning rate and weight decay making group params([!637](https://gitee.com/mindspore/mindspore/pulls/637))
+      * Support weights to be compiled according to shape([!1015](https://gitee.com/mindspore/mindspore/pulls/1015))
+      * delete some context param([!1100](https://gitee.com/mindspore/mindspore/pulls/1100))
+      * ImageSummary/ScalarSummary/TensorSummary/HistogramSummary([!1329](https://gitee.com/mindspore/mindspore/pulls/1329))([!1425](https://gitee.com/mindspore/mindspore/pulls/1425))
+* Executor and Performance Optimization
+    * Support doing evaluation while in training process, so that the accuracy of training can be easily obtained.
+    * Enable second-order optimization for resnet50, which can achieve 75.9% accuracy in 45 epochs (Resnet50 @ImageNet).
+    * Optimize pynative implementation and improve it's execution performance.
+    * Optimize summary record implementation and improve its performance.
+* Data processing, augmentation, and save format
+    * Support simple text processing, such as tokenizer/buildvocab/lookup.
+    * Support padding batch.
+    * Support split or concat dataset.
+    * Support MindDataset reading from file list.
+
+### Other Hardware Support
+* GPU platform
+    * New models supported: MobileNetV2, MobileNetV3.
+    * Support mixed precision training.
+    * Support device memory swapping.
+
+## Bugfixes
+* Python API
+    * An exception to the broadcast input data type check([!712](https://gitee.com/mindspore/mindspore/pulls/712))
+    * Fix issues assignsub return value 0([!1036](https://gitee.com/mindspore/mindspore/pulls/1036))
+    * Fix issue Conv2dBackpropInput bprop should return 3 instead of 2 items([!1001](https://gitee.com/mindspore/mindspore/pulls/1001))
+    * Fix sens shape error of TrainOneStepWithLossScaleCell([!1050](https://gitee.com/mindspore/mindspore/pulls/1050))
+    * Fix BatchNormGrad operator([!1344](https://gitee.com/mindspore/mindspore/pulls/1344))

+    * Fix memory leaks after execution in PyNatvie mode ([!1201](https://gitee.com/mindspore/mindspore/pulls/1201)).
+    * Fix HCCL failure in some special scenes ([!1204](https://gitee.com/mindspore/dashboard/projects/mindspore/mindspore/pulls/1204), [!1252](https://gitee.com/mindspore/dashboard/projects/mindspore/mindspore/pulls/1252)).
+    * Fix SSD network when Select failed, cann't find kernel info([!1449](https://gitee.com/mindspore/dashboard/projects/mindspore/mindspore/pulls/1449)).
