v0.16.0

• .handle / .serve methods doesn't (and will never again) accept a recreate/force/renew parameter
• the recreate process/instance happens only if the file has changed ( a lot better !!! )
• better orchestrator/process (doesn't use a ps/process dict, to kill process ... instead : use real events --> so the process will kill itselpt --> and so : graceful shutdown is better)
• and so : gunicorn compliant !!!! (but reboot is broken)
