v2.0.0

• #4: Support Python 3
• Windows MSI Installer
• Drop support for Python 2.6
• cherrypy.wsgiserver is no longer included as source package.
  CherryPy is still the recommended standalone WSGI server, and deployed with the
  binary installation. It is also installed as dependency by setup.py test.
  However if a source installation is used, either install cherrypy using
  pip install cherrypy or choose another server using the --server option.
• Configuration:
  • New options server and server_args
  • Removed ext_servers option
• Standalone server:
  • New command line option --server (defaults to cherrypy)
  • New command line option --no-config
  • Removed command line option -d use -vv instead
• Use py.test & tox
