+### Breaking Changes
+
+* The structure of APIs has changed to promote the re-use of types in the generated code. The APIs are still generated with Kopium in the first step, but there is a second stage where additional task is executed to reduce and rename the Kopium-generated types. While with this approach we can significantly reduce the surface of exposed APIs, it is also a breaking change. See [issue](https://github.com/kube-rs/gateway-api-rs/issues/38) for more context.
