+## 🌟 New features
+
+- You can now handle a GraphQL error using <type://GraphqlErrorHandler>. #4435
+  ```java
+  GraphqlErrorHandler errorHandler = new GraphqlErrorHandler() {
+    @Override
+    public HttpResponse handle(ServiceRequestContext ctx, ExecutionInput input,
+                               ExecutionResult result, @Nullable Throwable cause) {
+      final List<GraphQLError> errors = result.getErrors();
+      if (errors.stream().map(GraphQLError::getMessage)
+                .anyMatch(m -> m.startsWith("Unauthorized"))) {
+        return HttpResponse.of(HttpStatus.UNAUTHORIZED);
+      }
+      ...
+    }
+  };
+  GraphqlService
+    .builder()
+    .schemaFile(...)
+    .runtimeWiring(...)
+    .errorHandler(errorHandler) // 👈👈👈
+    .build();
+  ```
+
+- You can now easily configure client-side TLS key and certificates to support mTLS via
+  <type://ClientFactoryBuilder#tls(File,File)>. #4410
+  ```java
+  File keyCertChainFile = ...;
+  File keyFile = ...;
+  ClientFactory factory =
+    ClientFactory
+      .builder()
+      .tls(keyCertChainFile, keyFile)
+      .build();
+  WebClient
+    .builder()
+    .factory(factory)
+    .build();
+  ```
+
+- gRPC HTTP/JSON transcoding endpoint can now handle both the snake case and camel case query parameters
+  using <type://HttpJsonTranscodingOptions>. #4428
+  ```java
+  HttpJsonTranscodingOptions options =
+    HttpJsonTranscodingOptions
+      .builder()
+      // Try the original field name and camel case
+      // if it's not found via the original name.
+      .queryParamMatchRules(LOWER_CAMEL_CASE,
+                            ORIGINAL_FIELD)
+                            ...
+                            .build();
+  GrpcService
+    .builder()
+    .enableHttpJsonTranscoding(options)
+    .build();
+  ```
+
+- You can now use `OutputStream` to write data to a <type://StreamMessage> using
+  <type://StreamMessage#fromOutputStream(Consumer)>. #4402
+  ```java
+  StreamMessage.fromOutputStream(os -> {
+    // perform blocking operation
+    HttpData data0 = readDataFromBlockingDB(0);
+    os.write(data0);
+    HttpData data1 = readDataFromBlockingDB(1);
+    os.write(data1);
+    os.close();
+  }
+  ```
+
+- You can now convert an <type://AggregatedHttpRequest> to an <type://HttpRequest> with new headers. #4441
+  ```java
+  AggregatedHttpRequest req = ...
+  HttpRequest httpRequest = req.toHttpRequest(newHeaders);
+  ```
+
+## 📈 Improvements
+
+- N/A
+
+## 🛠️ Bug fixes
+
+- <type://GraphqlService> now respects the accept header correctly. #4451
+- <type://GrpcService> and <type://THttpService> no longer throw double subscription exceptions when
+  the request is aggregated in a decorator. #4449
+- The content-length header is automatically removed from <type://ResponseHeaders> for a server
+  streaming response in <type://GrpcService>. #4460
+- You no longer see a `NullPointerException` when using <type://EndpointSelectionStrategy#rampingUp()>. #4448
+- <type://DocService> no longer throw an exception when a protobuf message doesn't have any fields. #4436
+- You no longer see a 500 response when an empty multipart request is sent. #4432
+- The service name generated from a CGLIB-enhanced class no longer has a synthetic suffix in
+  <type://DocService>. #4430
+- Users can now use <type://ProtobufRequestConverterFunctionProvider> without encountering a potential
+  `ClassCastException`. #4429
+- Fixed a regression where `thrift0.9` is incompatible with Thrift 0.9.1 since Armeria 1.17.0. #4427
+- `enable-auto-injection` property is correctly added to the generated `spring-configuration-metadata.json`
+  file. #4425
