 - Docker Desktop now detects and attempts to avoid clashes between the "Docker subnet" and physical networks using RFC1918 addresses. For example if the host has a non-default route which overlaps with `192.168.65.0/24` then an alternative network will be chosen automatically. You can still override the choice as before via Docker Desktop settings and admin settings.
 - Docker Desktop no longer treats Stargz Snapshotter failures as fatal. If a failure occurs, Docker Desktop continues to run without the Stargz Snapshotter.
+- Ask Gordon no longer displays images with user provided URLs.
+- Ask Gordon now asks for confirmation before running all built-in and all user added MCP tools.
