# MCP Identity Gateway 1.31 release

Aembit has released [MCP Identity Gateway](/user-guide/deploy-install/mcp-identity-gateway) version 1.31.

Key Updates:

* **User identity on workload events**: The `userId` field now appears on `mcp.request` and `mcp.response` [workload events](/user-guide/deploy-install/mcp-identity-gateway/reference-mcp-gateway/#workload-events) when the MCP client is identified, making it easier to attribute MCP activity to authenticated users in audit reports.
* **Client-initiated session termination**: MCP clients can now end their session with the Gateway by sending an HTTP `DELETE` request to the `/mcp` endpoint, per [MCP specification section 2.5.5](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#session-management). See [Session management](/user-guide/deploy-install/mcp-identity-gateway/reference-mcp-gateway/#session-management) for the request contract.
