+## 🌈 1.0.2 `2026-02-05`
+
+### 🚀 Features
+
+- **ChatEngine**:
+  - Supports adaptation for AG-UI’s Activity-Snapshot/Delta events. A new `useAgentActivity` registration hook has been added, along with corresponding examples provided by @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+  - The ChatEngine event bus mechanism can now be used in scenarios without a UI. Examples are available at @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+  Error handling has been improved for `ToolCallRender` @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+  For several Delta events under the AG-UI protocol, automatic initialization is now supported to handle SSE Chunk streams in cases where no Snapshot is available @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+  Performance of Immutable JSON Patch has been optimized, and the `append` operation is now available for adding strings @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+- **ChatMarkdown**: The issue of increased packaging size caused by dependency on CherryMarkdown has been significantly resolved. Highlighting for code blocks is no longer built-in; businesses need to introduce this functionality manually via configuration @LzhengH @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119)).
+- **ChatSender**: The `readyToSend` property now allows for pre-sending validation to be handled  @LzhengH ([#4119](https://github.com/Tencent/tdesign-react/pull/4119).
+
+### 📝 Documentation

+- For **ChatEngine**, AI-friendly documentation has been added: AGENTS.md and llm.txt @carolin913 ([#4119](https://github.com/Tencent/tdesign-react/pull/4119))
