Supervisor2 2.0 is out. Changes from 2.0b1 to 2.0 include:

• pidfile written in daemon mode had incorrect pid.
• supervisorctl: tail (non -f) did not pass through proper error messages when supplied by the server.
• Log signal name used to kill processes at debug level.
• supervisorctl "tail -f" didn't work with supervisorctl sections configured with an absolute unix:// URL
• New "environment" config file option allows you to add environment variable values to supervisord environment from config file.
