 `vhostHTTPPort` and `vhostHTTPSPort` in frps can use same port with `bindPort`. frps will detect the connection's protocol and handle it correspondingly.
 
+What you need to pay attention to is that if you want to configure `vhostHTTPSPort` and `bindPort` to the same port, you need to first set `transport.tls.disableCustomTLSFirstByte` to false.
+
 We would like to try to allow multiple proxies bind a same remote port with different protocols in the future.

-* Configuration: We now support TOML, YAML, and JSON for configuration. Please note that INI is deprecated and will be removed in future releases. New features will only be available in TOML, YAML, or JSON. Users wanting these new features should switch their configuration format accordingly. #2521

-### Breaking Changes
-
-* Change the way to start the visitor through the command line from `frpc stcp --role=visitor xxx` to `frpc stcp visitor xxx`.
-* Modified the semantics of the `server_addr` in the command line, no longer including the port. Added the `server_port` parameter to configure the port.
-* No longer support range ports mapping in TOML/YAML/JSON.
+* `transport.tls.disableCustomTLSFirstByte` doesn't have any effect.
