### 其他变更
- Session 数据格式当前为 V3 版本，跨版本迁移细节见 [session-format-v2-to-v3/README.md](https://github.com/deepseek-ai/deepseek-harness/blob/dsh-v0.1.5-alpha.2/packages/session/session-format-v2-to-v3/README.zh.md) @tianyicui
- **Web 插件面板 API 调整：** 插件可通过 `sidebar.panellist` 与 `main` 注册全局面板；原 `conversation` Slot 迁移为 `main` 的 `conversation` key @imccyu
- **极简模式默认工具调整：** Web `minimal` 与 Python `sdk-minimal` 默认仅提供持久 shell，`str_replace_editor` 改为显式启用；持久 Bash 输出统一报告退出或超时状态 @koalazf99

<h3 id="en-v0.1.5-alpha.2">New Features</h3>
- Add previews for common document types in the right Sidebar, including Markdown, syntax-highlighted code, HTML, PDF, and images. by @imccyu, @Yifffan, @yixiangihsiang, @CreatixChu, @yudshj
- Let models explicitly deliver files in conversations, with right-Sidebar preview, default-app opening, and file-manager reveal. by @yudshj, @CreatixChu
- The `/feedback` command now supports detailed feedback submissions. by @CreatixChu
### Bug Fixes
- Keep pi-ai model settings available when catalog changes invalidate an existing configuration, preserving diagnostics and repair controls. by @LegGasai
- Validate and normalize custom-provider Base URLs before model discovery or provider creation, with inline feedback for invalid addresses. by @turtle2099
- Fix the Windows native folder picker opening behind other windows in the Web app. by @Elevator14B
- Fix the Composer placeholder remaining visible after whitespace is entered. by @CreatixChu
- Keep filesystem and Web guidance aligned with each agent's visible tools, so filtered subagents are not instructed to use unavailable tools. by @koalazf99
- Reject repeated MCP tool-list pagination cursors instead of hanging startup or synchronization, while keeping the last valid tool set available. by @grllll
- Fix npm installations that previously required a local `fs-ext` build. by @imccyu
### Improvements
- Improve Settings localization and accessibility by adding accessible names and localizing conversation display options and built-in model descriptions in Chinese. by @turtle2099
### Chores
- The current Session data format is V3. See [session-format-v2-to-v3/README.md](https://github.com/deepseek-ai/deepseek-harness/blob/dsh-v0.1.5-alpha.2/packages/session/session-format-v2-to-v3/README.md) for cross-version migration details. by @tianyicui
- **Web plugin panel API changes:** Plugins can register global panels through `sidebar.panellist` and `main`; the former `conversation` slot moves to the `conversation` key under `main`. by @imccyu
- **Minimal-profile default tools:** Web `minimal` and Python `sdk-minimal` are shell-only by default, with `str_replace_editor` available by explicit opt-in; persistent Bash reports completion and timeout status consistently. by @koalazf99
- Publish installable experimental Agent Teams packages; users must explicitly add the profile, which is not enabled by default. by @imccyu
