+## Reflection (& Resizing)
+
+There is experimental support for reflection in FlatBuffers, allowing you to
+read and write data even if you don't know the exact format of a buffer, and
+even allows you to change sizes of strings in-place.
+
+The way this works is very elegant; there is actually a FlatBuffer schema that
+describes schemas (\!) which you can find in `reflection/reflection.fbs`.
+The compiler, `flatc`, can write out any schemas it has just parsed as a binary
+FlatBuffer, corresponding to this meta-schema.
+
+Loading in one of these binary schemas at runtime allows you to traverse any
+FlatBuffer data that corresponds to it without knowing the exact format. You
+can query what fields are present, and then read/write them after.
+
+For convenient field manipulation, you can use the crate
+`flatbuffers-reflection` which includes both the generated code from the meta
+schema, as well as a lot of helper functions.
+
+And example of usage, for the time being, can be found in
+`tests/rust_reflection_test/src/lib.rs`. Two sets of APIs are provided:
+
+- [Unsafe getters/setters](https://docs.rs/flatbuffers-reflection/latest/flatbuffers_reflection/#functions),
+ which you can use when you are processing trusted data (either from a source you know, or has been verified)
+
+- Safe getters in [SafeBuffer](https://docs.rs/flatbuffers-reflection/latest/flatbuffers_reflection/struct.SafeBuffer.html),
+ which does verification when constructed so you can use it for any data source

+## C++ Callback API Generation
+
+FlatBuffers gRPC C++ code generation now optionally supports the modern gRPC Callback API.
+
+To enable generation of a `CallbackService` skeleton alongside the existing `Service` and async mixins, invoke `flatc` with both `--grpc` and `--grpc-callback-api`:
+
+```shell
+flatc --cpp --grpc --grpc-callback-api your_service.fbs
+```
+
+This adds (guarded by `#if defined(GRPC_CALLBACK_API_NONEXPERIMENTAL)`) a class:
+
+```cpp
+class YourService::CallbackService : public ::grpc::Service { /* reactor virtuals */ };
+```
+
+Each RPC shape maps to the appropriate reactor return type:
+
+- Unary -> `::grpc::ServerUnaryReactor*` Method(...)
+- Client streaming -> `::grpc::ServerReadReactor<Request>*`
+- Server streaming -> `::grpc::ServerWriteReactor<Response>*`
+- Bidi streaming -> `::grpc::ServerBidiReactor<Request, Response>*`
+
+Default generated implementations return `nullptr`; override in your derived class and return a reactor instance you manage (see gRPC docs for lifecycle patterns).
+
+If your gRPC library predates the stable callback API macro, the code inside the guard will be skipped (no breaking changes). Ensure you build against a recent gRPC (1.38+; verify current minimum in grpc repo) to use this feature.
+
+### Client Callback Stubs
+
+When `--grpc-callback-api` is supplied, the generated C++ client stub gains native callback / reactor based async methods in addition to the existing synchronous / generic async flavors, guarded by the same macro. For each RPC named `Foo`:
+
+Unary:
+
+```
+void async_Foo(::grpc::ClientContext*, const Request&, Response*, std::function<void(::grpc::Status)>);
+void async_Foo(::grpc::ClientContext*, const Request&, Response*, ::grpc::ClientUnaryReactor*);
+```
+
+Client streaming:
+
+```
+::grpc::ClientWriteReactor<Request>* async_Foo(::grpc::ClientContext*, Response*, ::grpc::ClientWriteReactor<Request>*);
+```
+
+Server streaming:
+
+```
+::grpc::ClientReadReactor<Response>* async_Foo(::grpc::ClientContext*, const Request&, ::grpc::ClientReadReactor<Response>*);
+```
+
+Bidirectional streaming:
+
+```
+::grpc::ClientBidiReactor<Request, Response>* async_Foo(::grpc::ClientContext*, ::grpc::ClientBidiReactor<Request, Response>*);
+```
+
+These map directly onto the native gRPC callback API factories (e.g. `CallbackUnaryCall`, `ClientCallbackWriterFactory::Create`, etc.) and do not spawn threads. Override the appropriate reactor callbacks per gRPC's documentation to drive I/O.
+
+If your build uses an older gRPC lacking the non-experimental macro, these symbols will not be emitted, preserving backwards compatibility.
