# v3.0.0 - TBD

- [#4238](https://github.com/hyperf/hyperf/issues/4238) Upgraded the minimum php version to `^8.0` for all components;

## BC breaks

- 框架移除了 `@Annotation` 的支持，全部使用 `PHP8` 原生注解 `Attribute`，更新前务必检查项目中，是否已经全部替换为 `Attribute`。

可以执行以下脚本，将 `Doctrine Annotations` 转化为 `PHP8 Attributes`.

**注意: 这个脚本只能在 2.2 版本下执行**

```shell
composer require hyperf/code-generator
php bin/hyperf.php code:generate -D app
```

- 升级模型脚本

> 因为模型基类增加了成员变量的类型支持，所以需要使用以下脚本，将其升级为新版本。

```shell
composer require hyperf/code-generator
php vendor/bin/regenerate-models.php $PWD/app/Model
```

- 框架为类库增加了更多的类型限制，所以从 `2.2` 更新到 `3.0` 版本时，需要跑一遍静态检测。

```shell
composer analyse
```
