-#### 1.1-beta2
-
-* Add Clash mode and persistence support **1**
-* Add TLS ECH and uTLS support for outbound TLS options **2**
-* Fix socks4 request
-* 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 socks4 request
-* Fix processing empty dns result
-
-#### 1.1-beta1
-
-* Add support for use with android VPNService **1**
-* Add tun support for WireGuard outbound **2**
-* Add system tun stack **3**
-* 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.
-
-See [Dial Fields](/configuration/shared/dial#udp_fragment)
-and [Listen Fields](/configuration/shared/listen#udp_fragment).
