Fixes connection problems around proxies and WireGuard tunnels. The checks iOS makes to decide whether it has internet now always go direct, so a proxy that stalls for a few seconds no longer makes the device look offline. Failed name lookups inside a WireGuard tunnel no longer stack up on each other, which could stall apps for a minute or more, and an old tunnel is now shut down properly when it is rebuilt after a network change.

New protocols: VLESS, Trojan and Shadowsocks 2022. Import vless:// and trojan:// links directly, and subscriptions now tell you which nodes were skipped and why. WireGuard fixes: - Name lookups inside a WireGuard tunnel now ask the resolver to recurse. Some resolvers answered "refused" or came back empty before, which looked like a broken tunnel. - If a VPN endpoint intercepts DNS inside its own tunnel, lookups retry over HTTPS automatically. You can also set a WireGuard proxy's DNS to https://1.1.1.1/dns-query. - UDP (QUIC) now travels through WireGuard proxies instead of being dropped. - Connections that cannot complete time out after 20 seconds instead of hanging, and the engine log now records handshakes, dials and DNS answers so problems can be diagnosed. Pasting a full URL into a proxy's address field is cleaned up to host:port automatically.

Fixes a bug where the VPN showed as connected but no data flowed. If the proxy port is taken by another app, Proxy Switchboard now moves to the next free port and Wi-Fi sharing shows the exact address in use.

Fixes a bug that could stop the VPN from connecting when another app was already using the same local port. The proxy port is now editable in Settings > Advanced, and when a port is busy the app moves to the next free one and shows the address other devices should actually use for Wi-Fi sharing.
