+When a client connects to the MCP server, a unique session ID is assigned to the client during the link:https://modelcontextprotocol.io/specification/2025-06-18/basic/lifecycle#initialization[initialization phase] and returned in the `Mcp-Session-Id` HTTP response header. For subsequent requests, the client must include the session ID in the `Mcp-Session-Id` request header.

+=== MCP Endpoint Discoverability
+The MCP endpoint is made available at `/mcp` under the context root of your application, e.g., `http://localhost:9080/myMcpApp/mcp`. For ease of discovery, the URL of the MCP endpoint for your Liberty hosted application is now output in the server logs on application startup.

+[#netty]
+== Netty‑based HTTP transport on Open Liberty
+
+Open Liberty now provides a Netty‑based HTTP transport as a beta preview. This change is an internal implementation swap for the underlying transport used for HTTP/1.1, HTTP/2, WebSocket, JMS and SIP communications. It is designed for zero migration: your applications and `server.xml` continue to behave the same. We are looking forward and counting on your feedback before GA!

+Previously, repository methods couldn't limit retrieval of results to subsets of entity attributes (commonly referred to as projections). Now, repository methods can return Java records that represent a subset of an entity. In addition, parameter-based `@Find` and `@Delete` methods earlier were not able to filter on conditions other than equality. Now more advanced filtering can be done in two different ways: typing the repository method parameter with a `Constraint` subtype or indicating the `Constraint` subtype by using the `@Is` annotation.
