1.0

================

• Copy sys.path to the worker process and ensure hupper is on the
  PYTHONPATH so that the subprocess can import it to start the worker.
  This fixes an issue with how zc.buildout injects dependencies into a
  process which is done entirely by sys.path manipulation.
  See copy sys.path to the worker process Pylons/hupper#27
