-## PaddlePaddle Fluid
-
-- PaddlePaddle发布版本v0.11.0包含一个新的特性*PaddlePaddle Fluid*. Fluid 是设计用来让用户像Pytorch和Tensorflow Eager Execution一样执行程序。在这些系统中，不再有*模型*这个概念，应用也不再包含一个用于描述Operator图或者一系列层的符号描述，而是像通用程序那样描述训练或者预测的过程。而Fluid与PyTorch或Eager Execution的区别在于Fluid不依赖Python提供的控制流，例如 if-else-then或者for，而是提供了基于C++实现的控制流并暴露了对应的用with语法实现的Python接口。例如：
-
-  https://github.com/PaddlePaddle/Paddle/blob/3df78ed2a98d37f7ae6725894cc7514effd5664b/python/paddle/v2/fluid/tests/test_while_op.py#L36-L44
-
-- 在v0.11.0版本中，我们提供了一个C++类`Executor`用于运行一个Fluid程序。Executor类似一个解释器。在未来的版本中，我们将提升和优化Executor成为一个调试器，就像GDB。并可能提供一些编译器，这个编译器会读取一个上文所描述的应用然后编译成一个等价的

-* 当使用编译选项`WITH_MKL=ON`时自动下载和编译Intel® [MKLML](https://github.com/01org/mkl-dnn/releases/download/v0.11/mklml_lnx_2018.0.1.20171007.tgz) 函数库.
-* [Intel® MKL-DNN on PaddlePaddle](https://github.com/PaddlePaddle/Paddle/tree/develop/doc/design/mkldnn):
-  - 完成了 11个 MKL-DNN 层: Convolution, Fully connectivity, Pooling, ReLU, Tanh, ELU, Softmax, BatchNorm, AddTo, Concat, LRN。
-  - 完成了 3个 MKL-DNN 网络: VGG-19, ResNet-50, GoogleNet
-  - 基于Intel Skylake 6148 CPU的[性能测试](https://github.com/PaddlePaddle/Paddle/blob/develop/benchmark/IntelOptimizedPaddle.md) : 相对于MKLML有2~3倍的训练加速。

-# v0.10.0版本
-
-我们非常高兴发布了PaddlePaddle V0.10.0版，并开发了新的[Python API](http://research.baidu.com/paddlepaddles-new-api-simplifies-deep-learning-programs/)。
-
-- 旧的Python API由于难以学习和使用已经过时了。使用旧版本的API至少需要两份python文件，分别是定义数据生成器和定义网络拓扑结构的文件。用户通过运行`paddle_trainer`的C++程序来启动PaddlePaddle任务，该程序调用Python解释器来运行定义网络拓扑结构的文件，然后通过迭代加载数据生成器提供的小批量数据启动训练循环。这与Python的现代编辑方式不符，比如Jupyter Notebook。
-
-- 新版的API被称为 *V2 API*，允许我们在单个.py文件中，通过编辑更短的Python程序来定义网络结构和数据。此外，该Python程序也可以在Jupyter Notebook中运行，因为PaddlePaddle可以作为共享库来被Python程序加载和使用。
-
-基于新的API，我们提供了一个在线的学习文档 [Deep Learning 101](http://book.paddlepaddle.org/index.en.html) 及其[中文版本](http://book.paddlepaddle.org/)。
-
-我们还致力于迭代更新新版API的在线文档，并将新版API引入分布式集群（包括MPI和Kubernetes）训练中。我们将在下一个版本中发布更多的内容。
-
-## 新特点

-* 支持矩形输入的CNN。
-* 为seqlastin和seqfirstin提供stride pooling。
-* 在`trainer_config_helpers`中暴露`seq_concat_layer/seq_reshape_layer`。
-* 添加公共数据集包：CIFAR，MNIST，IMDB，WMT14，CONLL05，movielens，imikolov。
-* 针对Single Shot Multibox Detection增加 Prior box layer。
-* 增加光滑的L1损失。

RELEASE.md

-# Release v0.11.0
+# Release Note
 
-## PaddlePaddle Fluid
-
-- Release 0.11.0 includes a new feature *PaddlePaddle Fluid*.  Fluid is
-  designed to allow users to program like PyTorch and TensorFlow Eager Execution.
-  In these systems, there is no longer the concept *model* and applications
-  do not include a symbolic description of a graph of operators nor a sequence
-  of layers. Instead, applications look exactly like a usual program that
-  describes a process of training or inference.  The difference between
-  Fluid and PyTorch or Eager Execution is that Fluid doesn't rely on Python's
-  control-flow, `if-then-else` nor `for`.  Instead, Fluid provides its
-  C++ implementations and their Python binding using the `with` statement.  For an example
-
-  https://github.com/PaddlePaddle/Paddle/blob/3df78ed2a98d37f7ae6725894cc7514effd5664b/python/paddle/v2/fluid/tests/test_while_op.py#L36-L44
-
-- In 0.11.0, we provides a C++ class `Executor` to run a Fluid program.
-Executor works like an interpreter. In future version, we will improve
-`Executor` into a debugger like GDB, and we might provide some compilers,
-which, for example, takes an application like the above one, and outputs
-an equivalent C++ source program, which can be compiled using
-[`nvcc`](http://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html)
-to generate binaries that use CUDA, or using
-[`icc`](https://software.intel.com/en-us/c-compilers) to generate binaries
-that make full use of Intel CPUs.
-
-## New Features
-
-* Release `PaddlePaddle Fluid`.
-* Add C-API for model inference

-
-# Release v0.10.0
-
-We are glad to release version 0.10.0.  In this version, we are happy to release the new 
-[Python API](http://research.baidu.com/paddlepaddles-new-api-simplifies-deep-learning-programs/).
-
-- Our old Python API is kind of out of date.  It's hard to learn and hard to
-  use.  To write a PaddlePaddle program using the old API, we'd have to write
-  at least two Python files: one `data provider` and another one that defines
-  the network topology.  Users start a PaddlePaddle job by running the
-  `paddle_trainer` C++ program, which calls Python interpreter to run the
-  network topology configuration script and then start the training loop,
-  which iteratively calls the data provider function to load minibatches.
-  This prevents us from writing a Python program in a modern way, e.g., in the
-  Jupyter Notebook.
-  
-- The new API, which we often refer to as the *v2 API*, allows us to write
-  much shorter Python programs to define the network and the data in a single
-  .py file.  Also, this program can run in Jupyter Notebook, since the entry
-  point is in Python program and PaddlePaddle runs as a shared library loaded
-  and invoked by this Python program.
-  
-Basing on the new API, we delivered an online interative
-book, [Deep Learning 101](http://book.paddlepaddle.org/index.en.html)
-and [its Chinese version](http://book.paddlepaddle.org/).
-
-We also worked on updating our online documentation to describe the new API.
-But this is an ongoing work.  We will release more documentation improvements
-in the next version.
-
-We also worked on bring the new API to distributed model training (via MPI and
-Kubernetes).  This work is ongoing. We will release more about it in the next
-version.
-
-## New Features
-
-* We release [new Python API](http://research.baidu.com/paddlepaddles-new-api-simplifies-deep-learning-programs/).
