+'''''''''
+
+There is a new Rust implementation of ``virtiofsd`` at
+``https://gitlab.com/virtio-fs/virtiofsd``;
+since this is now marked stable, new development should be done on that
+rather than the existing C version in the QEMU tree.
+The C version will still accept fixes and patches that
+are already in development for the moment, but will eventually
+be deleted from this tree.
+New deployments should use the Rust version, and existing systems
+should consider moving to it.  The command line and feature set
+is very close and moving should be simple.
