v0.4.0-preview.2

Breaking Changes

The v0.4.0-preview.2 release includes a breaking change to the Streamable HTTP transport's Stateless mode. Because Stateless mode no longer uses a session ID nor relies on data protection, client information like the client's name and version are no longer tracked across requests meaning McpServer.ClientInfo will always be null. If you need ClientInfo in your handlers, we recommend using the default stateful mode.
