 ## 为什么使用 frp ？

Release.md

@@ -1,9 +1,5 @@
-## Features
+## Fixes
 
-* `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.
+* HTTP vhost servers no longer support HTTP/1.1 `Upgrade: h2c` requests. Cleartext HTTP/2 prior-knowledge remains supported.
+* Fixed control-session replacement leaks when frpc reconnects through a half-open TCP multiplexed connection.
+* Fixed an SSH tunnel gateway panic when handling malformed exec requests.
