+An `InProcessGrpcServerFactory` picks up the `ServerInterceptorFilter` automatically.
+Any other server factory will require you to provide a `GrpcServerFactoryCustomizer` in which you can modify the factory by adding a filter, as shown in the following example:

@@ -10,6 +10,8 @@ This section covers the changes made from version 0.8.0 to version 0.9.0.
 * Upgrade to Spring Boot 3.5.0.
 * `StubFactory` contract changes: the "supports" method is now a static method (it is called before an instance is created).
 * Removed `GrpcClientFactoryCustomizer` in favour of `GrpcChannelBuilderCustomizer`.
+* Added ability to filter interceptors in in-process gRPC clients.
+* Added ability to filter global interceptors and service definitions - easy to do for `InProcessGrpcServer` and possible to do for `NettyGrpcServer` by registering a customizer.
