New Features

• Official Docker Image: Gunicorn now publishes official Docker images to GitHub Container Registry (PR #​3454)

  • Available at ghcr.io/benoitc/gunicorn
  • Based on Python 3.12 slim image
  • Uses recommended worker formula (2 × CPU + 1)

• PROXY Protocol v2 Support: Extended PROXY protocol implementation to support the binary v2 format in addition to the existing text-based v1 format (PR #​3451)

  • New --proxy-protocol modes: off, v1, v2, auto
  • auto mode (default when enabled) detects v1 or v2 automatically
  • v2 binary format is more efficient and supports additional metadata
  • Works with HAProxy, AWS NLB/ALB, and other PROXY protocol v2 sources
