[1.91.1] - 2026-11-15

Added

• Real TCP window (wssize) can remove the Window Scale option instead of lowering it: downloads on the connection then run at up to 64 KB per round trip instead of staying slow. Window Scale option, Remove the option under TCP, General in the set editor.

Changed

• An imported zapret --wssize without a scale, or with scale 0, sets Window Scale option to Remove the option in place of leaving the scale unchanged.

Fixed

• In TUN mode in a MikroTik RouterOS container, DNS lookups b4 made itself could time out, so the Community page could not sync and the DPI Detector failed.
• A connection the router opened itself, such as one through b4's SOCKS5 server, to an address of a proxy set stalled or was reset when another set listed its site and had a bypass strategy; on iptables only when the proxy set was enabled after b4 started. #597
