+# 2.3.1 Release Note
+
+## **1. Important Updates**
+
+- V2.3.1 is built on V2.3 by fixing known issues and releasing  precompiled binary that supports CUDA 11.6.
+
+## **2. Training Framework (distributed included)**
+
+### **(1) Function Optimization**
+
+#### API
+
+- Modify two initialization modes of `paddle.nn.initializer.KaimingUniform` and `paddle.nn.initializer.KaimingNormal`, to support multiple types of activation functions. ([#43721](https://github.com/PaddlePaddle/Paddle/pull/43721), [#43827](https://github.com/PaddlePaddle/Paddle/pull/43827))
+- Optimize the data pre-fetching function of `paddle.io.DataLoader`, so that it can support the setting of the `prefetch_factor` to set the cache size of pre-fetched data. This can avoid IO blocking when reading large blocks of data. ([#43674](https://github.com/PaddlePaddle/Paddle/pull/43674))
+
+#### **New dynamic graph execution mechanism**
+
+- Modify the initialization method of optional type Tensor in the new dynamic graph API logic to prevent data exceptions caused by early destruction. ([#42561](https://github.com/PaddlePaddle/Paddle/pull/42561))
+
+#### **New static graph executor**
+
+- Defer initialization of the thread pools in the  executor, to avoid creating thread pools for `programs` that execute only once (e.g.,`save, load, startup_program`, etc.). ([#43768](https://github.com/PaddlePaddle/Paddle/pull/43768))
+
+#### **Mixed precision training**
+
+- Disabling `state_dict` hook in `set_state_dict` in `paddle.nn.Layer`. ([#43407](https://github.com/PaddlePaddle/Paddle/pull/43407))
+
+#### **Distributed training**
+
+- Enabling tensor parallelism in `paddle.incubate.nn.functional.fused_attention` and `paddle.incubate.nn.functional.fused_feedforward`. ([#43505](https://github.com/PaddlePaddle/Paddle/pull/43505))
+
+#### **Others**
+
+- Adjust print format of the framework operator kernels to facilitate automated splitting and parsing. ([#42931](https://github.com/PaddlePaddle/Paddle/pull/42931))
+- Update the model quantization API to support the round-off in `rounding to nearest ties to even`, and support quantization in the range [-128, 127]. ([#43829](https://github.com/PaddlePaddle/Paddle/pull/43829))
+- Support AMP mixed precision training in quantization-aware training. ([#43689](https://github.com/PaddlePaddle/Paddle/pull/43689))
+- Add the `progress bar` at the beginning of quantization-aware training, so that it is easy to check the progress of quantization initialization. Skip the scale op when counting out_threshold to speed up the initialization process. ([#43454](https://github.com/PaddlePaddle/Paddle/pull/43454))
+- Support `conv` and `bn` fusion in the dynamic graph quantization training. Support the settings of skip_tensor_list in the static graph offline quantization, to skip some layers without quantization. ([#43301](https://github.com/PaddlePaddle/Paddle/pull/43301))
+
+### **(2) Performance Optimization**
+
+- Optimize`paddle.incubate.nn.functional.fused_attention` and `paddle.incubate.nn.functional.fused_feedforward`operators. Add `add_residual` property to control whether to perform add-`residual` operation in the last step. The performance of CAE model is improved by 7.7%. ([#43719](https://github.com/PaddlePaddle/Paddle/pull/43719))
+- Optimize `linspace` operator. Initialize three input Tensor of `start`,`stop` and `num` on CPU, to avoid GPU->CPU copy in the operator. This can speed up SOLOv2 model performance by 6%. ([#43746](https://github.com/PaddlePaddle/Paddle/pull/43746))
+
+### **(3) Bug Fix**
+
