## 2026-03-20 - 25.17.6 - fix(rustproxy-http)
disable HTTP/3 GREASE for client and server connections
- Switch the HTTP/3 server connection setup to use the builder API with send_grease(false)
- Switch the HTTP/3 client handshake to use the builder API with send_grease(false) to improve compatibility
