+
+## What's Changed (EN)
+
+### New Features
+
+- Added inline message editing, regeneration from a selected message, a thread panel, and conversation checkpoint support to the WebUI chat page. ([#7673](https://github.com/AstrBotDevs/AstrBot/pull/7673))
+- Added chat attachment previews and file signature checks in WebUI to improve attachment recognition and display before upload. ([commit](https://github.com/AstrBotDevs/AstrBot/commit/0748f0a42))
+- Added buffered intermediate messages for the non-streaming Agent Loop, allowing process messages such as tool calls to be surfaced in non-streaming scenarios. ([#7627](https://github.com/AstrBotDevs/AstrBot/pull/7627))
+- Reintroduced `/provider` as a built-in command for viewing and managing Provider-related information. ([#7691](https://github.com/AstrBotDevs/AstrBot/pull/7691))
+- Added an option to pin installed plugins with available updates to the top of the plugin page, with persisted preference storage. ([#7665](https://github.com/AstrBotDevs/AstrBot/pull/7665))
+- Added EPUB support for knowledge-base document upload, including EPUB parsing, file reading support, and tests. ([#7594](https://github.com/AstrBotDevs/AstrBot/pull/7594))
+
+### Improvements
+
+- Updated the FileReadTool description to mention image, PDF, and DOCX support, and improved modality checks for tool results. ([#7506](https://github.com/AstrBotDevs/AstrBot/pull/7506))
+- Unified documentation links across CLI output, configuration, Dashboard, and knowledge-base pages. ([#7709](https://github.com/AstrBotDevs/AstrBot/pull/7709))
+
+### Bug Fixes
+
+- Fixed missing normal replies when model output contains reasoning content. ([#7715](https://github.com/AstrBotDevs/AstrBot/pull/7715))
+- Added retries for transient DNS and connection errors in the QQ Official API flow. ([#7718](https://github.com/AstrBotDevs/AstrBot/pull/7718))
+- Fixed `RegexFilter` so it accepts both `str` and `re.Pattern`. ([#7633](https://github.com/AstrBotDevs/AstrBot/pull/7633))
+- Fixed a path traversal vulnerability in the backup importer. ([#7681](https://github.com/AstrBotDevs/AstrBot/pull/7681))
+- Dropped legacy `documents_fts` tables when present to avoid knowledge-base FTS migration issues. ([#7706](https://github.com/AstrBotDevs/AstrBot/pull/7706))
+- Fixed configuration failures for some domestic or custom OpenAI/Anthropic-compatible model providers caused by TLS certificate chains, proxy handling, or model-list capability differences. ([#7685](https://github.com/AstrBotDevs/AstrBot/pull/7685))
+- Changed MiniMax Token Plan Provider behavior to warn instead of blocking when a configured model is not in the hardcoded model list. ([#7692](https://github.com/AstrBotDevs/AstrBot/pull/7692))
+- Normalized invalid `required` flags in MCP schemas to avoid tool schema errors. ([#6077](https://github.com/AstrBotDevs/AstrBot/pull/6077))

+## ChatUI
+
+AstrBot includes a built-in ChatUI for talking to configured models directly in your browser.
+
+ChatUI supports these common workflows:
+
+- Create, rename, and delete conversations, and switch previous conversations from the sidebar.
+- Select the config profile, model provider, and model on the chat page; if Provider session separation is enabled, you can also choose a model for the current session only.
+- Send text, images, files, and voice input; uploaded attachments show previews and use file signature checks to help identify file types.
+- View model thinking, tool-call status, knowledge-base or web-search references, and per-message token and latency statistics.
+- Copy or regenerate existing replies, including regenerating with another model.
+- Edit a user message and continue generation from that point, or start a thread from a specific excerpt.
+- Switch between streaming/normal response modes and SSE/WebSocket transport modes.
+
+> [!NOTE]
+> To keep message delivery ordered, keep only one ChatUI page open for the same browser session. If you open chat in multiple tabs, the system may ask you to reconnect.
+
 ## Visual Configuration
 
 In the admin panel, you can configure AstrBot's plugins through visual configuration. Click `Configuration` in the left sidebar to enter the configuration page.

+## ChatUI
+
+AstrBot 内置 ChatUI，可在浏览器中直接与已配置的模型对话。
+
+ChatUI 支持以下常用能力：
+
+- 创建、重命名、删除对话，并在左侧会话列表中切换历史对话。
+- 在聊天页选择配置文件、模型提供商与模型；如果启用了 Provider 会话隔离，也可以为当前会话单独选择模型。
+- 发送文本、图片、文件与语音输入；上传附件时会展示预览，并根据文件签名辅助识别文件类型。
+- 查看模型思考过程、工具调用状态、知识库或网页搜索引用来源，以及每条回复的 Token 和耗时统计。
+- 对已有回复执行复制、重新生成，或使用其他模型重新生成。
+- 编辑用户消息后从该消息继续生成，也可以针对某段内容开启分支追问。
+- 切换流式/普通响应模式，以及 SSE/WebSocket 通信模式。
+
+> [!NOTE]
+> 为保证消息接收顺序，同一浏览器会话建议只保留一个 ChatUI 页面。如果你在多个标签页中同时打开聊天页面，系统可能会提示需要重新建立连接。
+
 ## 可视化配置
 
 在管理面板中，你可以通过可视化配置来配置 AstrBot 的插件。点击左栏 `配置` 即可进入配置页面。
