+## [4.28.0-beta.1] - 2026-09-02
+
+### Major Additions
+
+- Redesigned the WebUI pages for model providers, bots, and profiles, and consolidated logs, traces, conversation management, and data into the **Data & Logs** page. Removed the **Agent Runner** from model providers and embedded its settings into each profile. (#9820, #9825, #9821, #9883, #9846)
+- Redesigned the default and local T2I rendering. (#9803)
+- Enriched unified group metadata across messaging platform adapters. (#9851)
+- Automatically record readable names for unified message origins (UMOs), such as group and user names, making them easier to find in the WebUI. (#9909)
+- Added masked secret fields for sensitive values in the WebUI and plugin configurations. (#9824)
+- Added batch deletion to the WebUI skill management page. (#9906)
+- Added AnySearch as a built-in web search provider. (#9767)
+- Added support for password-style plugin configuration fields and masked sensitive profile fields by default. (#9824)
+
+### Major Optimizations

+- Fixed an issue where commands in Lark groups would not trigger when the bot mention appeared before the command. (#9872)
+- Isolated rate limits by unified message origin (UMO). (#9814)
+- Aligned Anthropic API Base URL handling with the OpenAI API; `/v1` must now be included in the configured URL. (#9802)
+- Fixed cached-token usage accounting for Anthropic and Gemini. (#9880, #9881)
+- Applied the `max_agent_step` configuration to scheduled-task and background-task agents. (#9801)
+- Preserved text in Lark mixed text-and-image messages. (#9841)
+- Displayed the create-folder button in the mobile persona manager. (#9812)

+- 重新设计 WebUI 的模型提供商页、机器人页和配置文件页，并将日志、追踪、对话管理、数据页综合为「数据与日志」页。移除模型提供商的 “Agent 执行器”，将其内嵌到各个配置文件中。 (#9820, #9825, #9821, #9883, #9846)
+- 重新设计默认和本地的 T2I 渲染效果。 (#9803)

+
+### 主要修复

+- 钉钉部分情况下扫码之后出现 CREATING 未知状态导致无法继续创建。 (#9808)
+- 修复飞书群里当 at 机器人在前而命令在后会无法触发命令的问题。 (#9872)
