There are quite a few new features that have been added since 0.7.1 so
0.7.1-1 is not suitable (it's not a bugfix release). And before making
a new release, it would be good to finish all the things that are only
half-working.

Maybe you can take a snapshot of the current hg if it works for you
and put the tarball on the unicorn page, something like
dolfin-unicorn-x.y.z.tar.gz?
