This release fixes a bug cause by linking all plug service instances to the installed plug. Runit uses a ./supervise in the service's directory to maintain state which would be clobbered when multiple services link to the same plug.
Now the virtualenv is copied to /srv/plug/plug_instances/ and linked into runit.
There is also a fix for uninstalling plugs leaving orphaned processes. Now Plug will stop the processes before removing them to prevent this.
