Add native security key registration, reference import, and signing on macOS and iOS. Store references in Vault metadata and route authentication through connection, Assistant, MCP, and agent forwarding flows.
Preserve signing cancellation and actionable authentication errors for security keys and Secure Enclave. Pin the released libssh2 forks as nested submodules and refresh package resolution.
Integrate AgentKit 0.18.1 with native authorization on macOS and iOS, device-local OAuth credentials, V43 configuration persistence, and Assistant authorization prompts.
Add HTTPS callback metadata, keep native callbacks safe across actor boundaries, and distinguish authorization setup failures from cancellation. Extend the external MCP server to negotiate 2025-03-26.
Add host-owned chat creation, model discovery, messaging, reading, and waiting with durable delivery receipts. Keep tool presentation compact, mark agent-authored messages, and prevent edits that would remove tool activity.
Adopt the signed AgentKit 0.16.0 release in the package requirement, resolved revision, and submodule.
