-* Hysteria2 `ignore_client_bandwidth` behavior update **1**
-* Fixes and improvements
-
-**1**:
-
-When `up_mbps` and `down_mbps` are set, `ignore_client_bandwidth` instead denies clients from using BBR CC.
-
-See [Hysteria2](/configuration/inbound/hysteria2/#ignore_client_bandwidth).

-
-See [Hysteria2](/configuration/outbound/hysteria2/).
-
-#### 1.11.0-beta.14
-
-* Allow adding route (exclude) address sets to routes **1**
-* Fixes and improvements
-
-**1**:
-
-When `auto_redirect` is not enabled, directly add `route[_exclude]_address_set`
-to tun routes (equivalent to `route[_exclude]_address`).
-
-Note that it **doesn't work on the Android graphical client** due to
-the Android VpnService not being able to handle a large number of routes (DeadSystemException),
-but otherwise it works fine on all command line clients and Apple platforms.
-
-See [route_address_set](/configuration/inbound/tun/#route_address_set) and
-[route_exclude_address_set](/configuration/inbound/tun/#route_exclude_address_set).

-* Make GSO adaptive **1**
-
-**1**:
-
-For WireGuard outbound and endpoint, GSO will be automatically enabled when available,
-see [WireGuard Outbound](/configuration/outbound/wireguard/#gso).
