 6. [X2Paddle添加内置的Caffe自定义层](./docs/user_guides/add_caffe_custom_layer.md)
 
 ## 更新历史
-2019.08.05  
-1. 统一tensorflow/caffe/onnx模型转换代码和对外接口
-2. 解决上一版caffe2fluid无法转换多分支模型的问题
-3. 解决Windows上保存模型无法加载的问题
-4. 新增optimizer，优化代码结构，合并conv、batch_norm的bias和激活函数  
-
 2020.12.09
 1. 新增PyTorch2Paddle转换方式，转换得到Paddle动态图代码，并动转静获得inference_model。
 方式一：trace方式，转换后的代码有模块划分，每个模块的功能与PyTorch相同。

 3. 新增TensorFlow op（14个）：Neg、Greater、FloorMod、LogicalAdd、Prd、Equal、Conv3D、Ceil、AddN、DivNoNan、Where、MirrorPad、Size、TopKv2
 4. 新增Optimizer模块，主要包括op融合、op消除功能，转换后的代码可读性更强，进行预测时耗时更短。
 
-**如果你需要之前版本的tensorflow2fluid/caffe2fluid/onnx2fluid，可以继续访问release-0.9分支，获取之前版本的代码使用。**
