+Previously, the "Welcome to Checkmk" snapin was not shown in the sidebar on freshly installed sites. The initial admin user created during site installation was missing the `created_on_version` attribute, so Checkmk treated it as a pre-2.5 user and excluded the welcome snapin from the default sidebar.
