-* Add comment filter for config **4**
-* Add option for allow optional proxy protocol header
-* Add half close for smux
-* Set UDP DF by default **5**
-* Set default tun mtu to 9000
-* Update gVisor to 20220905.0

-*1*:
-
-In previous versions, Android VPN would not work with tun enabled.
-
-The usage of tun over VPN and VPN over tun is now supported, see [Tun Inbound](/configuration/inbound/tun#auto_route).
-
-*2*:
-
-In previous releases, WireGuard outbound support was backed by the lower performance gVisor virtual interface.
-
-It achieves the same performance as wireguard-go by providing automatic system interface support.
-
-*3*:
-
-It does not depend on gVisor and has better performance in some cases.
-
-It is less compatible and may not be available in some environments.
-
-*4*:
-
-Annotated json configuration files are now supported.
-
-*5*:
-
-UDP fragmentation is now blocked by default.
-
-Including shadowsocks-libev, shadowsocks-rust and quic-go all disable segmentation by default.
