 Other changes to VCL
+When the ``.path`` field of a backend declaration is used to define a
+Unix domain socket as the backend address, and the socket file does
+not exist or is not accessible at VCL load time, then a warning is
+issued, but the VCL load is allowed to continue. Previously, the load
+would fail in that case. This makes it easier to start the peer
+component listening at the socket, or set the socket's permissions,
+after starting Varnish or loading VCL. If the socket still cannot be
+accessed when a fetch is attempted, then the fetch fails.
