+## **Introduction to Key Changes**
+
+### Features
+**1. gRPC Multi-Service Support**
+
+Implemented multi-service registration for KiteX gRPC, please refer to [Multiple Services](/docs/kitex/tutorials/advanced-feature/multi_service/).
+
+**2. Acquire Kitex RPCInfo**
+
+Added methods for easy retrieval of RPC information from RPCInfo, please refer to [Acquire RPC information](/docs/kitex/tutorials/basic-feature/acquire_rpcinfo/).
+
+### Optimizations
+**1. Map Generic Call**
+
+Map generic call supports returning []byte for binary fields via SetBinaryWithByteSlice option.
+
+**2. RPCInfo asynchronous use**
+
+Added an option to disable reusing RPCInfo, facilitating asynchronous usage, please refer to please refer to [Acquire RPC information](/docs/kitex/tutorials/basic-feature/acquire_rpcinfo/#12-asynchronous-usage).
+
+
+### Others
+
+Upgraded frugal to [v0.1.12](https://github.com/cloudwego/frugal/releases/tag/v0.1.12), fixing some concurrency issues when compiling types, especially the issue when registering new modules which may conflict with sonic.  
+  It's STRONGLY SUGGESTED updating both frugal and sonic to the latest version by  
+  ```shell
+    go get github.com/cloudwego/frugal@latest
+    go get github.com/bytedance/sonic@latest
+  ```
+## **Full Release Log**
+
+### Feature:
+[[#1051](https://github.com/cloudwego/kitex/pull/1051)] feat(grpc): support gRPC multi-service on a server  
+[[#1189](https://github.com/cloudwego/kitex/pull/1189)] feat(rpcinfo): add kitexutil methods for the convenience to fetch rpc information from RPCInfo  
+[[#1176](https://github.com/cloudwego/kitex/pull/1176)] feat(tool): add an environment variable to make it easier to debug kitex tool  
+[[#1173](https://github.com/cloudwego/kitex/pull/1173)] feat(rpcinfo): allow disable rpcinfo reuse for async reference  
+[[#1172](https://github.com/cloudwego/kitex/pull/1172)] feat(retry): client.WithSpecifiedResultRetry should have higher priority  
+[[#1150](https://github.com/cloudwego/kitex/pull/1150)] feat(proxy): add an interface to customize proxy middleware to replace the default implementation  
+[[#1159](https://github.com/cloudwego/kitex/pull/1159)] feat(generic): support returning []byte for binary fields in map generic  
+[[#1153](https://github.com/cloudwego/kitex/pull/1153)] feat(retry): add Extra for retry.FailurePolicy for better extension  
+### Optimize:
+[[#1187](https://github.com/cloudwego/kitex/pull/1187)] optimize(tool): add an option to keep resp for kitex tool  
+[[#1183](https://github.com/cloudwego/kitex/pull/1183)] optimize(meshheader): retrieve rip from meshheader and write it to TransInfo  
+[[#1178](https://github.com/cloudwego/kitex/pull/1178)] optimize(bizErr): recurse to obtain BizErr to avoid additional Error encapsulation in the middle, resulting in unwrap results that are not BizErr  
+### Fix:
+[[#1126](https://github.com/cloudwego/kitex/pull/1126)] fix(generic): the issue of structs cache of generic call has dirty data under multiple services scene  
+[[#1168](https://github.com/cloudwego/kitex/pull/1168)] fix(tool): remove the pointer to java.Object in generated file for [CodecDubbo](https://github.com/kitex-contrib/codec-dubbo)  
+[[#1169](https://github.com/cloudwego/kitex/pull/1169)] fix(tool): empty struct generate wrong struct  
+[[#1166](https://github.com/cloudwego/kitex/pull/1166)] fix(generic): issue of deep copy function generation when map key type is binary  
+[[#1155](https://github.com/cloudwego/kitex/pull/1155)] fix(tool): add import package 'context' for gRPC client.go  
+
