frp/Release.md

Features

• UDP packet payloads for ordinary UDP proxies and SUDP now use a dedicated binary codec when frpc and frps successfully negotiate the capability under wire protocol v2, using a more compact wire representation. Wire protocol v1 remains JSON; wire protocol v2 falls back to JSON UDPPacket when the peer does not support or did not negotiate the capability.

Fixes

• Fixed a server panic and remote denial of service caused by a client sending a negative pool_count. Negative values are now rejected before work-connection pool resources are allocated.
