* Fix processing empty dns result

*1*:

Switching modes using the Clash API, and `store-selected` are now supported,
see [Experimental](/configuration/experimental).

*2*:

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).

#### 1.0.2

* Fix processing empty dns result

*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).
