1. New option -smuxver , default is set to 1 which is compatible with previous releases. Now you can set -smuxver to 2 to enable per-stream flow control to make back-pressure on the remote sender and prevent connections from starving. Adjust -streambuf to set per-stream max memory usage, eg: -streambuf 2097152.
   Related issues: https://github.com/xtaci/kcptun/issues/722, https://github.com/xtaci/smux/issues/18
   (Important note: smux version 1 and version 2 are not compatiblity, you need to upgrade on both sides to enable this feature.)
2. Writable notification in kcp-go became more accurate.
3. Fixed a bug in kcp, which may retransmit more segments than required. https://github.com/xtaci/kcp-go/releases/tag/v5.4.10

Recommended to upgrade

1. When the sliding window is full which blocks packet sending, smux will prioritize to send data from the least sent stream. (You need to upgrade on the data sender.)
2. when -tcp is specified, server will listen on both tcp & udp port.
