Yup. Just updated. The multigrid demo still gives the warning, just once, while the warning seems to have gone away for my own stokes code.

PS The firedrake-update script always fails for me. Locks-up my machine, essentially; I can't even get a screenshot of the mysterious error messages which appear with mouse clicks. So then I download a fresh copy and it is fine (but slow over the network). Using ubuntu 18.04. Any ideas?

It happens for me in the multigrid demo when injecting the BC value (defined on V rather than W.sub(0)).
