+> The Endpoint Picker (EPP), InferenceObjective and InferenceModelRewrite APIs, and Body Based Router (BBR) packages have moved to new repositories:
+> - EPP and associated APIs: [llm-d/llm-d-inference-scheduler](https://github.com/llm-d/llm-d-inference-scheduler)
+> - BBR: [llm-d/llm-d-inference-payload-processor](https://github.com/llm-d/llm-d-inference-payload-processor)
+>
+> No new code will be accepted to these packages in this repository, and they will be archived soon. This move was proposed and discussed in [issue #2430](https://github.com/kubernetes-sigs/gateway-api-inference-extension/issues/2430).
+>
+> This repository will continue to host the **lightweight EPP (LWEPP)** and the **InferencePool API**, and will remain the primary location for the development and maintenance of **conformance tests**.
