RuyiSDK V0.7 版本今日正式发布。GCC上游社区合并了PLCT提交的香山南湖微架构补丁，RuyiSDK包管理器正在对最新的gnu-upstream进行新版本的打包分发，预计近日将发布；RuyiSDK 官网已公开内测；操作系统安装器新增了Milk-V Duo S、Milk-V Mars、Milk-V Vega等产品的集成，截止本版本为止，Milk-V当前全产品线已经初步集成到RuyiSDK包管理器（Milk-V Duo S、Milk-V Mars 设备暂时未到位测试验证后续补充，欢迎有设备的开发者们试用反馈）。
更多更新详见下方详情，欢迎大家试用并提供反馈和建议。下一个开发版本 RuyiSDK V0.8 版本将在 4 月 9 日发布。
RuyiSDK 0.7 对应的包管理器版本也为 0.7.0，已于今日发布。您可移步 GitHub Releases 或 ISCAS 镜像源下载体验。
本次 RuyiSDK 包管理器的更新主要包含了以下内容：
- 修复了在部分系统上找不到 TLS 根证书的问题。
- Ruyi 设备安装器（
ruyi device provision）现在可以帮忙制作安装介质（如 LiveUSB）了。
此外，我们完善了持续集成基础设施：从此版本开始，RuyiSDK 包管理器的所有版本发布将以自动化方式完成了。这有助于我们更高效、更可靠地推进开发工作、解决问题。
欢迎试用或来上游围观；您的需求是我们迭代开发的目标和动力。
集成开发环境 VSCode开发部分目前征集到一位内部兼职开发者，开始尝试基于VSCode实现 Milkv 开发板的集成开发工作。
香山南湖的微架构支持已合入GCC上游，继续推进RUYISDK多版本GCC的支持工作，更新了“-march=help”特性的支持。
