[1.39.2] - 2026-03-03

• ADDED: TCP Port Filter — B4 no longer only captures TCP port 443. You can now configure custom TCP ports per set (e.g., 80,5222,8000-9000) in the TCP settings tab, just like UDP. Port 443 is always included. Firewall rules, packet processing, and the monitor all update automatically — no restart needed. Useful for services like Telegram (port 5222), WhatsApp (5222-5223), Signal (4433), XMPP, and others that use non-443 TCP ports.
• IMPROVED: Set Import/Export — the exported JSON is now much shorter and easier to read. Only settings you actually changed are shown; everything else is left out since it uses defaults. A b4_version tag is included so you can tell which B4 version a shared set was made with.
• IMPROVED: Simpler import flow — pasting a set JSON now applies it immediately (no more forgetting to click "Apply"). Added Copy and Paste buttons for quick sharing.
• IMPROVED: Lower memory usage — fixed several memory leaks and added automatic memory management.
• FIXED: Network interface not visible on MikroTik — veth interfaces (used by MikroTik containers) were incorrectly hidden. They now show up properly in the interface list.
