+# Release 0.6.0-beta
+
+## Major Features and Improvements
+### Ascend 910 Training and Inference Framework
+* New models
+    * There are official, research and community under modelzoo.
+        * Official is maintained  with the newest APIs by MindSpore team,  MaskRCNN are added.
+        * Research is uploaded by researchers for official review, and APIs may not  be updated in time.
+        * Community reprints the relevant links of partner research results.
+    * Hub added on the same level as modelzoo, synchronous storage of materials needed for official hub web pages which will be launched soon.
+    * Support pre-trained models, few lines of code can be used to download and load pre-trained models, supporting inference or transfer learning.
+* Frontend and user interface
+    * Supports user side operator compilation and graph execution error rendering.
+    * Uniform definition dynamic learning rate behavior in optimizers.
+    * Support IndexSlice in sparse expression.
+    * Support use parent construct method during construct.
+    * Support asynchronous execution save checkpoint file.
+    * Support implicit type conversion in pynative mode.
+    * User interfaces change log
+      * unform learning rate behavior in optimizers([!2755](https://gitee.com/mindspore/mindspore/pulls/2755))
+      * rename operator of sparse optimizer([!3217](https://gitee.com/mindspore/mindspore/pulls/3217))
+      * move profiler module from mindinsight to mindspore([!3075](https://gitee.com/mindspore/mindspore/pulls/3075))
+      * VOCDataset output change to multi-columns([!3093](https://gitee.com/mindspore/mindspore/pulls/3093))
+      * GetDatasize feature([!3212](https://gitee.com/mindspore/mindspore/pulls/3212))
+      * dataset: modify config api([!2936](https://gitee.com/mindspore/mindspore/pulls/2936))
+* Executor and performance optimization
+    * Decouple C++ and python, so make the architecture more extensible.
+    * Parameter Server for distributed deep learning supported.
+    * Serving：a flexible service deployment framework for deep learning models.
+    * Memory reuse is enhanced, and the batch size of Bert large model is increased from 96 to 160 on a single server.
+* Data processing, augmentation, and save format
+    * Support MindRecord save operator after  date processing
+    * Support automatic fusion operator, such as decode/resize/crop
+    * Support CSV dataset loading
+### Other Hardware Support
+* GPU platform
+    * New model supported: ResNext50, WarpCTC and GoogLeNet.
+    * Support hyperparametric search and data enhanced automl on GPU.
+    * Support Resnet50 automatic parallel in GPU backend.
+
