+## [4.28.1] - 2026-09-14
+
+We live in stories we collectively believe in.
+
+我们活在共同相信的故事里。
+
+### Additions and Optimizations
+
+- Added paginated ChatUI history loading and improved chat settings, the message composer, and streaming interactions. Reasoning is now displayed by default, and workspace code previews use Shiki highlighting. (#9667, #10021, #10020, #10023)
+- Added provider source filters and sticky group headers to model selection, and improved provider configuration dialogs. (#10084, #10007)
+- Added adaptive input image processing for the built-in Agent: resize or convert images when needed and turn animated images into frame montages. Preserve static image dimensions in CUA sandboxes and warn when images may exceed provider upload limits. (#9703, #10071)
+- Unified `/new` and `/reset` to start a new conversation, with permissions configurable in command management. (#10004)
+- Added desktop update download progress and reduced bundled WebUI font and diagram assets. (#10050, #10034)
+- Improved configuration slider robustness. (#10037)
+- Standardized provider request User-Agent headers to include the AstrBot version. (#10082)
+
+### Fixes
+
+- ‼️ Preserved original image attachment paths after event cleanup so agents can continue to access attachments. (#10042)
+- Fixed plugin updates through URL and file installation. (#10053)
+- Fixed model selection in WebChat side threads and restored session model fallback for proactive agents. (#10065, #10028)
+- Fixed delivery of skills-like fallback replies during streaming. (#10025)
+- Made scheduled agents honor session context compression settings and record failures when the runner ends in an error state. (#9992, #9987)
+- Fixed OpenAI endpoint resolution when `api_base` is empty. (#10079)
+- Fixed missing fields, swallowed error codes, and parameter validation in web search tools. (#9979)
+- Spaced out concurrent URL-cleaning rate limiter waiters in the knowledge base. (#10015)
+- Improved Lark private-message delivery by falling back from rejected open IDs to known chat IDs without duplicating successful sends. (#10018)
+- Fixed QQ Official C2C streaming responses missing the closing frame. (#10069)
+- Reduced Telegram polling and conflict error log spam. (#10027, #10046)
+- Fixed mention-all handling in message outlines. (#9993)
+- Fixed current conversation deletion when the active conversation must be resolved from storage, and used WebChat session titles as a fallback in conversation history. (#10003, #9983)
+- Batched console log rendering to prevent WebUI freezes. (#9988, #9990)
+- Rejected stale WebUI assets in desktop-managed mode and excluded temporary dashboard build artifacts from PyPI source packages. (#9898, #10036)
+
+### Upgrade Notes
+
+- `/reset` now follows `/new`: the built-in Agent starts a new conversation while preserving the old history and current persona. Third-party Agent backends reset their stored session IDs and may not preserve old records. (#10004)
+
+## 中文
+
+### 新增与优化
+
+- 新增 ChatUI 历史消息分页加载，优化聊天设置、消息输入框和流式交互体验。默认显示推理过程，工作区代码预览使用 Shiki 语法高亮。 (#9667, #10021, #10020, #10023)
+- 为模型选择器新增提供商来源筛选和分组标题吸顶，优化模型提供商配置对话框。 (#10084, #10007)
+- 为内置 Agent 新增自适应输入图片处理：按需缩放、转换格式，并将动图转为多帧拼图。在 CUA 沙箱下保留静图尺寸，图片可能超过模型提供商上传限制时给出警告。 (#9703, #10071)
+- 统一 `/new` 和 `/reset` 的新建对话行为，并支持在指令管理中配置权限。 (#10004)
+- 新增桌面端更新下载进度显示，精简 WebUI 打包的字体和图表资源。 (#10050, #10034)
+- 改进配置滑块的健壮性。 (#10037)
+- 统一模型提供商请求的 User-Agent，使其包含 AstrBot 版本。 (#10082)
+
+### 修复
+
+- ‼️ 在事件清理后保留图片附件原图路径，使 Agent 能够继续访问附件。 (#10042)
+- 修复通过 URL 或文件安装方式更新插件出现的问题。 (#10053)
+- 修复 WebChat 侧边线程的模型选择，恢复主动 Agent 对会话模型的回退逻辑。 (#10065, #10028)
+- 修复流式模式下 skills-like 回退回复未送达的问题。 (#10025)
+- 使定时任务 Agent 遵循会话上下文压缩设置，并在执行器以错误状态结束时记录任务失败。 (#9992, #9987)
+- 修复 `api_base` 为空时的 OpenAI 接口地址解析。 (#10079)
+- 修复网页搜索工具的字段丢失、错误码吞没和参数校验问题。 (#9979)
+- 修复知识库 URL 清洗限流器中并发等待请求未错开执行的问题。 (#10015)
+- 提高飞书私聊消息送达可靠性：open ID 被拒绝时回退到已知 chat ID，避免重复发送已成功的消息。 (#10018)
+- 修复 QQ 官方机器人 C2C 流式回复缺少结束帧的问题。 (#10069)
+- 减少 Telegram 轮询和冲突错误的重复日志。 (#10027, #10046)
+- 修复消息概要中全体成员提及的处理顺序。 (#9993)
+- 修复需要从持久化存储解析当前对话时的删除行为，并在对话历史中使用 WebChat 会话标题作为回退。 (#10003, #9983)
+- 批量渲染控制台日志，避免 WebUI 卡顿。 (#9988, #9990)
+- 修复桌面端托管模式加载过期 WebUI 资源的问题，并从 PyPI 源码包中排除临时前端构建产物。 (#9898, #10036)
+
+### 升级提示
+
+- `/reset` 现在与 `/new` 行为一致：内置 Agent 会创建新对话，保留旧历史并继承当前人格；第三方 Agent 后端会重置保存的会话 ID，不保证保留旧记录。群聊默认权限跟随对话隔离设置，已有指令权限设置继续生效。 (#10004)
