## What's Changed

hotfix of 4.17.0

- 修复：当开启了 “启用文件日志” 后，无法启动 AstrBot，报错 `ValueError: Invalid unit value while parsing duration: 'files'`。这是由于日志轮转设置中保留配置错误导致的，已通过根据备份数量正确设置保留参数进行修复。
- fix: When "Enable file logging" is turned on, AstrBot fails to start with error `ValueError: Invalid unit value while parsing duration: 'files'`. This is due to an incorrect retention configuration in the log rotation setup, which has been fixed by properly setting the retention parameter based on backup count.
