If you use the spec plugin (part of the pinocchio package) and want to upgrade to the new version of nose, you can safely do this now, because here is the new spec plugin, (I hope) fully compatible with the new plugin API. Note that it’s not an official release of pinocchio, but just a testing version for the impatient. I haven’t changed other pinoccho plugins, so you’re safe to upgrade your pinocchio 0.1 installation to this version. Let me know if something doesn’t work as expected.
