+title: 1.2.1
+description: Vide 1.2.1 更新日志。
+---
+
+Vide 1.2.1 修复宏展开悬停在配置预定义宏和嵌套宏实参场景下的显示问题，并调整 1.2.0 更新日志里的自动重构说明。
+
+## 修复
+
+### 宏展开悬停
+
+- 宏展开经过 `vide.toml` 中配置的预定义宏时，悬停信息现在会继续显示完整展开结果，不再丢失展开内容。([#245](https://github.com/pascal-lab/vide/pull/245) by [@hongjr03](https://github.com/hongjr03))
+- 展开结果现在保留预处理 trace 中的换行和缩进，悬停里的 `Expands to` 代码块更接近实际展开后的代码形态。([#245](https://github.com/pascal-lab/vide/pull/245) by [@hongjr03](https://github.com/hongjr03))
+
+## 文档
+
+- 调整 1.2.0 更新日志里的自动重构说明，让新增代码动作的范围更准确。([#244](https://github.com/pascal-lab/vide/pull/244) by [@hongjr03](https://github.com/hongjr03))

+title: 1.2.1
+description: Vide 1.2.1 release notes.
+---
+
+Vide 1.2.1 fixes macro expansion hover output for configured predefines and nested macro arguments, and updates the 1.2.0 code action notes.
+
+## Fixes
+
+### Macro Expansion Hover
+
+- Macro hover now keeps showing the complete expansion when the output passes through predefines configured in `vide.toml`. ([#245](https://github.com/pascal-lab/vide/pull/245) by [@hongjr03](https://github.com/hongjr03))
+- Expansion output now preserves line breaks and indentation from the preprocessor trace, so the hover's `Expands to` code block more closely matches the expanded code. ([#245](https://github.com/pascal-lab/vide/pull/245) by [@hongjr03](https://github.com/hongjr03))
+
+## Documentation
+
+- Updated the 1.2.0 release note wording for automatic refactoring code actions so the listed scope is more accurate. ([#244](https://github.com/pascal-lab/vide/pull/244) by [@hongjr03](https://github.com/hongjr03))
