AI Summary

This patch release extends Wire Protocol v2 support to UDP-based proxies (SUDP) and XTCP work connections, ensuring consistent payload framing and improving compatibility during mixed deployments of v1 and v2 protocols.

Key Highlights

  • UDP-based proxy payloads now support wire protocol v2
  • Improved SUDP compatibility during mixed wire protocol deployments
  • XTCP work connection NatHoleSid messages follow the selected wire protocol

New Features

  • transport.wireProtocol = "v2" now applies to UDP-based proxy payloads
  • Improved SUDP compatibility during mixed transport.wireProtocol deployments
  • XTCP work connection NatHoleSid messages follow selected transport.wireProtocol

Full Release Notes

## Features

* `transport.wireProtocol = "v2"` now also applies to UDP-based proxy payloads, including ordinary UDP and SUDP, so their payload framing is consistent with the selected wire protocol.
* Improved SUDP compatibility during mixed `transport.wireProtocol` deployments, allowing frps to bridge payloads between v1/default and v2 SUDP clients.
* XTCP work connection `NatHoleSid` messages now follow the selected `transport.wireProtocol`.

## Compatibility Notes

* When enabling `transport.wireProtocol = "v2"` for SUDP, upgrade both the proxy and visitor frpc instances first, or keep them on `v1` until both sides are upgraded.
