我来对这个git diff进行审查：

1. 语法逻辑：

• changelog格式正确，符合Debian的changelog规范
• 版本号格式(2.0.19.1)符合语义化版本控制
• 维护者信息和日期格式正确
• 变更类型标记(fix/feat)使用恰当

2. 代码质量：

• 变更描述清晰简洁
• 每个变更点都有明确的说明
• 使用了标准的项目维护者信息格式

3. 代码性能：

• changelog本身不涉及性能问题
• 但从变更内容看，添加了命令白名单验证和DTK配置覆盖，这些都是安全性和配置管理相关的改进

4. 代码安全：

• 添加命令白名单验证是一个很好的安全实践，可以有效防止命令注入攻击
• DTK配置覆盖功能增加了系统的灵活性，但需要确保配置文件权限设置正确

改进建议：

1. 变更描述可以更具体一些：

• "add command whitelist validation for notification actions" 可以改为 "implement command whitelist validation to prevent command injection in notification actions"
• "add DTK preference override configuration" 可以改为 "add support for DTK preference override configuration via /etc/dde-shell/config"

2. 建议在changelog中添加相关的bug编号或issue链接，方便追踪

3. 考虑添加安全相关的警告信息，提醒用户注意配置文件权限

4. 日期显示为2026年，这明显是个错误，应该更正为当前日期

总体来说，这是一个格式正确、内容合理的changelog变更，主要改进了系统的安全性和配置灵活性。建议按照上述建议进行优化。
