+## 0.60.6 — 2026-07-29
+
+- 新对话的工作目录选择改为可直接输入检索的下拉框，不再额外占用一行搜索框；同时支持键盘快速选择。
+
 ## 0.60.5 — 2026-07-29
 
 - 新对话仍会明确指定文件保存位置，同时目录选择更快捷：最近使用的目录会自动选中并置顶，目录较多时可以直接搜索。

 ### 2026-07-29
 
+- **07-29 / 0.60.6 / 新对话目录选择改可搜索组合框**:将上一版独立搜索框 + 原生 select 合并为单一 combobox，同一输入区完成已选目录展示、即时过滤和下拉选择，并补方向键、Enter、Esc、失焦恢复与 ARIA 状态；最近目录置顶、明确选择 working_dir 和新建目录入口均保持不变。纯前端改动，无依赖、API、schema 或 migration；全量 387 测试通过（17 项按环境跳过）。
 - **07-29 / 0.60.5 / 新对话目录选择提速**:保留首发前明确选择 working_dir 的归档约束；本机最近实际使用目录在候选中自动选中、置顶并标记，目录达到 6 个时按需显示搜索框，目录较少时维持原有简洁界面；同步精简“文件保存位置”文案。纯前端改动，无 API、schema、migration 或目录绑定语义变化；相关静态资源与无 DB 路由 18 项测试通过。
 - **07-29 / 0.60.4 / 工具失败信号分层 + run_python 同错保护 + wire 健康观测**:管理端保留近7天低阈值全量事实，默认把近24h活跃数据拆成跨任务系统性故障、单任务反复失败、按设计非零退出的质量门，已归零记录沉入历史区；空输出 shell 关联最近 assistant tool_call 补 `search/no match` / `dependency probe` 等稳定类别。RepeatGuard 仅将 `run_python` traceback+非零退出纳入同错 streak，普通 shell exit 1 保持原语义。新增只读 `/v1/admin/tool-wire-health`，按 model_profile+tool 对既有 `tool_salvaged/tool_malformed` 计算24h/7d抢救率，无新表、migration、索引或执行策略变化。全量387测试通过（17项按环境跳过）。
