Version 2.2.0
Bug Fixes:
* Correct the description of the return value for
daemon.is_detach_process_context_required.
* Set a sensible default for Distribution.script_name.
This works around a bug in Setuptools which calls commands before
the Distribution is initialised.
Changes:
* The test suite now relies on the test discovery feature in
‘unittest’. This feature is in Python version 2.7 and later.
* Improve performance of daemon.close_all_open_files.
