Version 3.8.1.1

New Features

• DNS search domains: connection profiles now support DNS search domains, with validation in the profile editor.
• Connection warnings in the tray: connection errors and timeouts are now reported as warning balloons from the tray icon.

Improvements

• Faster and more reliable per-application traffic classification under heavy connection load: process lookups no longer stall packet processing, which could delay LAN traffic and occasionally route traffic of closing connections through the wrong path.
• Clearer connection timeout messages: an error that changes cause is reported with the current reason, and stale statuses are cleared on recovery.
• More robust DNS configuration: apply failures are reported and retried, settings are cleaned up on disconnect, and invalid DNS entries are handled consistently.
• Updated bundled .NET runtime to 10.0.12 and third-party libraries.

Bug Fixes

• 32-bit Windows: the x86 installer now ships a 32-bit command-line tool (wiresock-connect-cli.exe); previously it included a 64-bit build that could not start.
• Windows 7 (32-bit): fixed a .NET runtime crash in the application, the services and the CLI.
• Windows 7: "entry point not found" error dialogs no longer appear when an error is logged.
• DNS: IPv6 DNS responses are no longer discarded by Windows when queries are redirected, so name resolution no longer falls back to IPv4 with a delay.
• Kill Switch: fixed high CPU usage when the tunnel kept failing to connect without a network route (for example, with Wi-Fi off); improved network lock filtering around the WireGuard endpoint and SOCKS5 relay, and the lock state is preserved across sleep and disconnect.
• Dual-tunnel: fixed egress-selection races that could send malformed frames.
• Fixed resource leaks and race conditions on failed start, stop, restart and watchdog recovery that could leave the tunnel stuck or terminate the process.
