+ECH (Encrypted Client Hello) is a TLS extension that allows a client to encrypt the first part of its ClientHello
+message, see [TLS#ECH](/configuration/shared/tls#ech).
+
+uTLS is a fork of "crypto/tls", which provides ClientHello fingerprinting resistance,
+see [TLS#uTLS](/configuration/shared/tls#utls).

+*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.
+
+See [Dial Fields](/configuration/shared/dial#udp_fragment)
+and [Listen Fields](/configuration/shared/listen#udp_fragment).
