+## 0.6.0
+
+### request.path_params
+
+The biggest change here is that endpoint signatures are no longer:
+
+```python
+async def func(request: Request, **kwargs) -> Response
+```
+
+Instead we just use:
+
+```python
+async def func(request: Request) -> Response
+```
+
+The path parameters are available on the request as `request.path_params`.
+
+This is different to most Python webframeworks, but I think it actually ends up
+being much more nicely consistent all the way through.
+
+### app.url_for(name, **path_params)
+
+Applications now support URL reversing with `app.url_for(name, **path_params)`.
+
+### app.routes
+
+Applications now support a `.routes` parameter, which returns a list of `[Route|WebSocketRoute|Mount]`.
+
+### Route, WebSocketRoute, Mount
+
+The low level components to `Router` now match the `@app.route()`, `@app.websocket_route()`, and `app.mount()` signatures.
