# Release 0.3.0-alpha

## Major Features and Improvements

### Differential Privacy Model Training

Differential Privacy is coming! By using Differential-Privacy-Optimizers, one can still train a model as usual, while the trained model preserved the privacy of training dataset, satisfying the definition of
differential privacy with proper budget.
* Optimizers with Differential Privacy([PR23](https://gitee.com/mindspore/mindarmour/pulls/23), [PR24](https://gitee.com/mindspore/mindarmour/pulls/24))
    * Some common optimizers now have a differential privacy version (SGD/
    Adam). We are adding more.
    * Automatically and adaptively add Gaussian Noise during training to achieve Differential Privacy.
    * Automatically stop training when Differential Privacy Budget exceeds.
* Differential Privacy Monitor([PR22](https://gitee.com/mindspore/mindarmour/pulls/22))
    * Calculate overall budget consumed during training, indicating the ultimate protect effect.
