[1.40.0] - 2026-03-08
- ADDED: Mass delete sets — you can now select multiple sets at once and delete them all together. Click the "Select" button in the toolbar, check the sets you want to remove, then click "Delete". Includes "Select All" for quick bulk cleanup.
- ADDED: Multidisorder mode — sends fake overlap packets before every real segment (not just the first one), flooding DPI with garbage data so it can't reassemble your traffic correctly. Enable "Fake Per Segment" in Combo or Disorder fragmentation settings and choose how many fakes to send per segment.
- ADDED: New fake payload types — two new options in Faking settings: "All Zeros" (sends empty-looking data) and "Inverted Original" (sends a flipped copy of the real data). Some networks respond better to these than the default payloads.
- ADDED: New Discovery presets for multidisorder mode — Discovery can now automatically test these new techniques when searching for the best bypass configuration.
- ADDED: Upload GeoIP/GeoSite files — you can now upload
.datfiles directly from your computer using the "Upload" button inSettings > Geo Databases. - 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. - CHANGED: Main Set removed — there is no longer a special "main" set. All sets are now equal and independent. Your existing main set will be converted into a regular set automatically.
- CHANGED: Connection Bytes Limits moved to Settings — TCP and UDP connection bytes limits are now in
Settings > Core > Queue Settingsinstead of being tied to a specific set. - IMPROVED: Device list sorting — devices are now sorted alphabetically by name, with selected devices always shown at the top for easier access.
- FIXED: Set Import not working on Android — pasting a set configuration from the clipboard was not possible on Android devices.
- 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_versiontag 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 —
vethinterfaces (used by MikroTik containers) were incorrectly hidden. They now show up properly in the interface list.
