我来审查这段 git diff，这是一个 Debian 包 changelog 文件的变更。

语法逻辑

• Debian changelog 的格式是正确的，遵循了标准格式：
  • 包名和版本号 (dde-manual-content (3.0.4))
  • 发行版和紧急程度 (unstable; urgency=medium)
  • 变更内容 (* fix: remove unused image assets)
  • 维护者信息 (zhangkun zhangkun2@uniontech.com)
  • 时间戳 (Thu, 16 Oct 2025 21:05:50 +0800)
• 日期格式正确，使用了标准的 RFC 5322 格式
• 时间戳时区正确 (+0800)

代码质量

• changelog 条目简洁明了，清晰地描述了变更内容
• 使用了标准的 "fix:" 前缀来表示修复性变更
• 维护者信息完整，包含姓名和邮箱

代码性能

• 这是一个 changelog 文件，不涉及性能问题

代码安全

• changelog 文件本身不涉及安全问题
• 维护者邮箱使用了公司域名 (@uniontech.com)，符合企业开发规范

改进建议

1. 考虑在变更描述中提供更多细节，例如移除了哪些具体的图像资源，这样可以帮助其他开发者和用户更好地理解变更内容。例如：

   * fix: remove unused image assets (notification.png, settings.png)
   

2. 考虑添加一个空行来分隔不同版本的条目，这样可以提高可读性：

   dde-manual-content (3.0.4) unstable; urgency=medium
   
     * fix: remove unused image assets
   
   -- zhangkun <zhangkun2@uniontech.com>  Thu, 16 Oct 2025 21:05:50 +0800
   
   dde-manual-content (3.0.3) unstable; urgency=medium
   

3. 如果移除的图像资源在之前的版本中被引用过，可能需要考虑添加一个说明，告知用户这些资源已被移除，以避免可能的混淆。

总体而言，这个变更在语法和格式上都是正确的，只需要一些小的改进来提高信息的完整性和可读性。
