I want this release to focus on two things: logging and limiting resources.

Logging:

• Implement gunicorn access log format #947
  • Implement access log format #1191
  • Implement gunicorn access log format #947
• Allowing log_config to accept ConfigParser instance or a file object #1716
• unfavorable logger name "uvicorn.error" #562
• Add example of logging config file #491

Limiting resources:

• Further timeouts and resource limiting. #157
  • Implement --timeout-request-start flag #1685
  • --timeout-request-complete ??
• How do I cancel a streaming response on shutdown? #451
  • Add --timeout-graceful-shutdown parameter #1824

Extra:

• add run_server(server) convenience func #1012
• Override default --reload-dir if passing sub-directories of cwd #1700
• Fix shutdown event on Windows in reloader #1584
  • I need someone with Windows to test that.
• Improve ProxyHeadersMiddleware #1611
  • I've already reviewed. I'm waiting for the author. We probably need to add more comments over there, it's hard to follow the logic, even if the code looks good.
• Support custom SSL Context #806
