 MXNet Change Log
 ================
+## 1.3.0
+
+### New Features - Gluon RNN layers are now HybridBlocks
+- In this release, Gluon RNN layers such as `gluon.rnn.RNN`, `gluon.rnn.LSTM`, `gluon.rnn.GRU` becomes `HybridBlock`s as part of [gluon.rnn improvements project](https://github.com/apache/incubator-mxnet/projects/11) (#11482).
+- This is the result of newly available fused RNN operators added for CPU: LSTM([#10104](https://github.com/apache/incubator-mxnet/pull/10104)), vanilla RNN([#11399](https://github.com/apache/incubator-mxnet/pull/11399)), GRU([#10311](https://github.com/apache/incubator-mxnet/pull/10311))
+- Now many dynamic networks that are based on Gluon RNN layers can now be completely hybridized, exported, and used in the inference APIs in other language bindings such as R, Scala, etc.
+
+### MKL-DNN improvements
+- Introducing more functionality support for MKL-DNN as follows:
+  - Added support for more activation functions like, "sigmoid", "tanh", "softrelu". ([#10336](https://github.com/apache/incubator-mxnet/pull/10336))
+  - Added Debugging functionality: Result check ([#12069](https://github.com/apache/incubator-mxnet/pull/12069)) and Backend switch ([#12058](https://github.com/apache/incubator-mxnet/pull/12058)).
+
+### New Features - Gluon Model Zoo Pre-trained Models
+- Gluon Vision Model Zoo now provides MobileNetV2 pre-trained models (#10879) in addition to
+  AlexNet, DenseNet, Inception V3, MobileNetV1, ResNet V1 and V2, SqueezeNet 1.0 and 1.1, and VGG
+  pretrained models.
+- Updated pre-trained models provide state-of-the-art performance on all resnetv1, resnetv2, and vgg16, vgg19, vgg16_bn, vgg19_bn models (#11327 #11860 #11830).
+
+### New Features - Clojure package (experimental)
+- MXNet now supports the Clojure programming language. The MXNet Clojure package brings flexible and efficient GPU computing and state-of-art deep learning to Clojure. It enables you to write seamless tensor/matrix computation with multiple GPUs in Clojure. It also lets you construct and customize the state-of-art deep learning models in Clojure, and apply them to tasks, such as image classification and data science challenges.([#11205](https://github.com/apache/incubator-mxnet/pull/11205))
+- Checkout examples and API documentation [here](http://mxnet.incubator.apache.org/api/clojure/index.html).
+
+### New Features - Synchronized Cross-GPU Batch Norm (experimental)
+- Gluon now supports Synchronized Batch Normalization (#11502).
+- This enables stable training on large-scale networks with high memory consumption such as FCN for image segmentation.
+
+### New Features - Sparse Tensor Support for Gluon (experimental)
+- Sparse gradient support is added to `gluon.nn.Embedding`. Set `sparse_grad=True` to enable when constructing the Embedding block. ([#10924](https://github.com/apache/incubator-mxnet/pull/10924))
+- Gluon Parameter now supports "row_sparse" storage type, which reduces communication cost and memory consumption for multi-GPU training for large models. `gluon.contrib.nn.SparseEmbedding` is an example empowered by this. ([#11001](https://github.com/apache/incubator-mxnet/pull/11001), [#11429](https://github.com/apache/incubator-mxnet/pull/11429))
+- Gluon HybridBlock now supports hybridization with sparse operators ([#11306](https://github.com/apache/incubator-mxnet/pull/11306)).
+
+### New Features - Control flow operators (experimental)
+- This is the first step towards optimizing dynamic neural networks with variable computation graphs, by adding symbolic and imperative control flow operators. [Proposal](https://cwiki.apache.org/confluence/display/MXNET/Optimize+dynamic+neural+network+models+with+control+flow+operators).
+- New operators introduced: foreach([#11531](https://github.com/apache/incubator-mxnet/pull/11531)), while_loop([#11566](https://github.com/apache/incubator-mxnet/pull/11566)), cond([#11760](https://github.com/apache/incubator-mxnet/pull/11760)).
+
+### New Features - Scala API Improvements (experimental)
+- Improvements to MXNet Scala API usability([#10660](https://github.com/apache/incubator-mxnet/pull/10660), [#10787](https://github.com/apache/incubator-mxnet/pull/10787), [#10991](https://github.com/apache/incubator-mxnet/pull/10991))
+- Symbol.api and NDArray.api would bring new set of functions that have complete definition for all arguments.
+- Please see this [Type safe API design document](https://cwiki.apache.org/confluence/display/MXNET/Scala+Type-safe+API+Design+Doc) for more details.
+
+### New Features - Rounding GPU Memory Pool for dynamic networks with variable-length inputs and outputs (experimental)
+- MXNet now supports a new memory pool type for GPU memory (#11041).
+- Unlike the default memory pool requires exact size match to reuse released memory chunks, this new memory pool uses exponential-linear rounding so that similar sized memory chunks can all be reused, which is more suitable for all the workloads with dynamic-shape inputs and outputs. Set environment variable `MXNET_GPU_MEM_POOL_TYPE=Round` to enable.
+
+### New Features - Topology-aware AllReduce (experimental)
+- This features uses trees to perform the Reduce and Broadcast. It uses the idea of minimum spanning trees to do a binary tree Reduce communication pattern to improve it. This topology aware approach reduces the existing limitations for single machine communication shown by mehods like parameter server and NCCL ring reduction. It is an experimental feature ([#11591](https://github.com/apache/incubator-mxnet/pull/11591)).
+- Paper followed for implementation: [Optimal message scheduling for aggregation](https://www.sysml.cc/doc/178.pdf).
+- Set environment variable `MXNET_KVSTORE_USETREE=1` to enable.
+
+### New Features - Export MXNet models to ONNX format (experimental)
+- With this feature, now MXNet models can be exported to ONNX format([#11213](https://github.com/apache/incubator-mxnet/pull/11213)). Currently, MXNet supports ONNX v1.2.1. [API documentation](http://mxnet.incubator.apache.org/api/python/contrib/onnx.html).
+- Checkout this [tutorial](http://mxnet.incubator.apache.org/tutorials/onnx/export_mxnet_to_onnx.html) which shows how to use MXNet to ONNX exporter APIs. ONNX protobuf so that those models can be imported in other frameworks for inference.
+
+### New Features - TensorRT Runtime Integration (experimental)
+- [TensorRT](https://developer.nvidia.com/tensorrt) provides significant acceleration of model inference on NVIDIA GPUs compared to running the full graph in MxNet using unfused GPU operators. In addition to faster fp32 inference, TensorRT optimizes fp16 inference, and is capable of int8 inference (provided the quantization steps are performed). Besides increasing throughput, TensorRT significantly reduces inference latency, especially for small batches.
+- This feature in MXNet now introduces runtime integration of TensorRT into MXNet, in order to accelerate inference.([#11325](https://github.com/apache/incubator-mxnet/pull/11325))
+- Currently, its in contrib package.
+
+### New Examples - Scala
+- Refurnished Scala Examples with improved API, documentation and CI test coverage. ([#11753](https://github.com/apache/incubator-mxnet/pull/11753), [#11621](https://github.com/apache/incubator-mxnet/pull/11621) )
+- Now all Scala examples have:
+  - No bugs block in the middle
+  - Good Readme to start with
+  - with Type-safe API usage inside
+  - monitored in CI in each PR runs
+
+### Maintenance - Flaky Tests improvement effort
+- Fixed 130 flaky tests on CI. Tracked progress of the project [here](https://github.com/apache/incubator-mxnet/projects/9).
+- Add flakiness checker (#11572)
+
+### Maintenance - MXNet Model Backwards Compatibility Checker
+- This tool ([#11626](https://github.com/apache/incubator-mxnet/pull/11626)) helps in ensuring consistency and sanity while performing inference on the latest version of MXNet using models trained on older versions of MXNet.
+- This tool will help in detecting issues earlier in the development cycle which break backwards compatibility on MXNet and would contribute towards ensuring a healthy and stable release of MXNet.
+
+### Maintenance - Integrated testing for "the Straight Dope"
+- ["Deep Learning - The Straight Dope"](http://gluon.mxnet.io) is a deep learning book based on Apache MXNet Gluon that are contributed by many Gluon users.
+- Now the testing of this book is integrated in the nightly tests.
