-* Add [exclude route support](/configuration/inbound/tun) for TUN inbound
-* Add `udp_disable_domain_unmapping` [inbound listen option](/configuration/shared/listen) **1**
 * Fixes and improvements

+#### 1.6.0
+
+* Fixes and improvements
+
+Important changes since 1.5:
+
+* Our [Apple tvOS client](/installation/clients/sft) is now available in the App Store 🍎
+* Update BBR congestion control for TUIC and Hysteria2 **1**
+* Update brutal congestion control for Hysteria2
+* Add `brutal_debug` option for Hysteria2
+* Update legacy Hysteria protocol **2**
+* Add TLS self sign key pair generate command
+* Remove [Deprecated Features](/deprecated) by agreement
+
 **1**:
 
-If enabled, for UDP proxy requests addressed to a domain,
-the original packet address will be sent in the response instead of the mapped domain.
+None of the existing Golang BBR congestion control implementations have been reviewed or unit tested.
+This update is intended to address the multi-send defects of the old implementation and may introduce new issues.
+
+**2**
+
+Based on discussions with the original author, the brutal CC and QUIC protocol parameters of
+the old protocol (Hysteria 1) have been updated to be consistent with Hysteria 2
 
-This option is used for compatibility with clients that
-do not support receiving UDP packets with domain addresses, such as Surge.
