+title: ACP Registry is stabilized

+description: Announcement that the ACP Registry RFD has been completed and the registry is stabilized.
+---
+
+**Published:** March 9, 2026
+
+The ACP Registry RFD has moved to Completed and the initial version of the registry is stabilized.
+
+The registry gives ACP clients a standard way to discover, install, and configure compatible agents. It introduces a curated catalog and a shared manifest format so editors and other clients do not need to invent their own integration metadata.
+
+If you want to explore the shipped experience, start with [ACP Registry](/get-started/registry). For the design history and rationale, see the [ACP Agent Registry RFD](/rfds/acp-agent-registry).

+title: Implementation information for agents and clients
+sidebarTitle: Implementation information
+description: Protocol update introducing optional implementation metadata during initialization.
+---
+
+**Published:** October 24, 2025
+
+ACP now allows agents and clients to provide information about themselves to the other party during initialization.
+
+The [InitializeRequest](/protocol/schema#initializerequest) message now includes an optional clientInfo field, and the [InitializeResponse](/protocol/schema#initializeresponse) message includes an optional agentInfo field.
+
+This information can be used by clients to show users which agent is running and what version, by both sides to track usage metrics for which agents and clients are most popular among their users, and to help track down issues tied to particular implementation versions.
+
+This follows the existing pattern laid out in the [Model Context Protocol](https://modelcontextprotocol.io/specification/2025-06-18/basic/lifecycle#initialization).
+
+This is being introduced as an optional field for now for backwards compatibility. It is possible it will be made required in a future version of the protocol, like MCP, so that both sides can count on this information being available.
+
+For the user-facing protocol guide, see [Implementation Information](/protocol/initialization#implementation-information).
