# v0.20.4 Release Notes

> v0.20.2 -> v0.20.4

> **Note**: Supersedes the withdrawn `v0.20.3` tag, which did not run. All commits from `v0.20.2..HEAD` are folded into this release; the surface documented below is the only public form.

## Summary

Plugs Agenvoy into the MCP ecosystem with a dual-transport client adapter that merges global and per-session config, and tightens the tool registry boundary against silent execution of user-defined API endpoints. Scheduler runtime gains hot-reloading and catch-up for runs missed across reboots, while the TUI adds a top-level main view alongside polished provider-list and calculator interactions. Detailed documentation moves from the repo into GitHub Wiki.

接入 MCP 生態：新增同時支援 stdio 與 HTTP transport、global 與 per-session 配置可合併的 client adapter，並收斂工具註冊邊界以阻擋使用者自訂 API endpoint 的靜默執行。Scheduler 取得熱重載與重啟期間錯過任務的補跑能力；TUI 新增頂層 main view，並修飾 provider 列表與計算機互動。詳細文件由 repo 遷至 GitHub Wiki。
