 ## Unreleased
 
++ [新增] 管理后台提示词管理支持多选批量删除。
++ [新增] 新增定义拉取GitHub提示词源功能。
+
+## v0.0.6 - 2026-05-22
+
 + [新增] 管理后台支持配置模型渠道，前端当前无需鉴权即可直接使用后端渠道能力。
 + [优化] 统一整理后端错误提示、AI 代理、图片节点生成与重试、参考图缺失处理等细节。
 + [优化] 后端模型代理路径调整为 OpenAI 风格。

 # 待测试
 
+- 管理后台 `/admin/prompts` 新增提示词批量删除，需要确认多选、确认弹窗、删除后列表刷新和筛选条件下删除行为。
+- 管理后台 `/admin/settings` 的私有配置新增提示词定时同步开关和 Cron 表达式；开启后后端会按配置同步内置 GitHub 远程提示词源，需要确认保存配置和到点同步行为。
 - 管理后台 `/admin/settings` 中的渠道模型列表获取和模型测试已改为走后端接口，前端不再直接读取或转发 API Key，需要确认保存后、编辑中和已有渠道三种场景都能正常拉取模型和测试连通性。
