这个提交主要是更新了 dde-session 的版本号，从 2.0.3 升级到 2.0.4。此外，还增加了一条发布说明。从代码审查的角度来看，这个提交没有明显的语法或逻辑错误，但以下几点需要注意：

1. 版本号管理：确保版本号的更新遵循了项目的版本控制策略，比如语义化版本控制（Semantic Versioning）。

2. 发布说明：在发布说明中，应该详细说明这次更新的内容，包括新增功能、修复的 bug、性能改进等。虽然当前提交只提到了 "Release 2.0.4"，但建议提供更详细的信息，以便用户了解这次更新的具体内容。

3. 签名：提交信息末尾的签名（-- WuJiangYu <[email protected]> Thu, 03 Jul 2025 17:13:14 +0800）是正确的，但建议使用全名而不是缩写，以提高可读性。

4. 格式：提交信息应该遵循项目的提交信息格式规范，以确保一致性。如果项目有特定的提交信息模板，应该遵循该模板。

5. 测试：虽然这个提交主要是版本号和发布说明的更新，但建议在发布新版本之前进行充分的测试，确保新版本的功能和稳定性。

6. 文档更新：如果新版本包含了对用户文档的更改，确保文档也相应更新。

综上所述，这个提交在语法和逻辑上没有问题，但在版本管理和发布说明的详细程度、签名格式、格式一致性、测试和文档更新方面可以进一步改进。
