+
+### Breaking
+
+- Remove `SERVICE_FQN` to avoid upgrade confusion ([#222](https://github.com/github/twirp-rs/pull/222))
+
+#### Breaking: Allow custom headers and extensions for twirp clients and servers; unify traits; unify error type ([#212](https://github.com/github/twirp-rs/pull/212))
+
+- No more `Context`. The same capabilities now exist via http request and response [Extensions](https://docs.rs/http/latest/http/struct.Extensions.html) and [Headers](https://docs.rs/http/latest/http/header/struct.HeaderMap.html).
+- Clients and servers now share a single trait (the rpc interface).
+- It is possible to set custom headers on requests (client side) and it's possible for server handlers to read request headers and set custom response headers.
+- The same ☝🏻 is true for extensions to allow interactivity with middleware.
+- All the above is accomplished by using `http::request::Request<In>` and `http::response::Response<Out>` where `In` and `Out` are the individual rpc message types.
+- We have unifyied and simplified the error types. There is now just `TwirpErrorResponse` which models the [twirp error response spec](https://twitchtv.github.io/twirp/docs/spec_v7.html#error-codes).
+
+
+#### Breaking: Generate service fqn ([#221](https://github.com/github/twirp-rs/pull/221))
+
+Applications will need to remove any manual service nesting they are doing today.
+
+In 0.8.0, server consumers of this library have to know how to properly construct the fully qualified service path by using `nest` on an `axum` `Router` like so:
+
+```rust
+let twirp_routes = Router::new()
+        .nest(haberdash::SERVICE_FQN, haberdash::router(api_impl));
+```
+
+This is unnecessary in 0.9.0 (the generated `router` function for each service does that for you). Instead, you would write: 
+
+``` rust
+let twirp_routes = haberdash::router(api_impl);
+```
+
+It is still canonical (but not required) to then nest with a `/twirp` prefix (the examples show this).
+
+### Other
+
+- Allow mocking out requests ([#220](https://github.com/github/twirp-rs/pull/220))
+- Swap twirp and twirp-build readmes. Replace the repo readme with a symlink to twirp's readme. ([#215](https://github.com/github/twirp-rs/pull/215))
+- Update the content of the readme ([#216](https://github.com/github/twirp-rs/pull/216))
+- Include the readme in rustdoc ([#225](https://github.com/github/twirp-rs/pull/225))
