[1.34.0] - 2026-02-10

  • ADDED: Randomized Segment 2 Delay - instead of a fixed delay between TCP/UDP segments, you can now set a min–max range. Each packet picks a random delay within your range, making your traffic look more natural and harder for DPI to fingerprint. If both values are the same, it works exactly like before.
  • ADDED: Redesigned Dashboard - the dashboard now shows what actually matters:
    • Device Activity - see which devices on your network are connecting to which domains (e.g., your PlayStation, iPhone, or laptop), with connection counts per domain.
    • Domains Not In Any Set - quickly spot domains that aren't covered by any bypass set yet, with one-click "Add to set" buttons.
    • Bypass stats - at a glance, see total connections, how many are being bypassed, and current throughput.
    • Active Sets overview with clickable chips to jump to set configuration.
  • ADDED: The dashboard now tracks all network traffic, not just bypassed connections. This means device activity and domain lists populate even before you configure any sets.
  • IMPROVED: Set editor now opens as a full page instead of a popup window, giving you much more space to work with when configuring your bypass sets.
  • ADDED: TCP Timestamp faking strategy - a new way to make fake packets look wrong to the real server (so it ignores them) while still fooling DPI. Instead of using a low TTL or wrong sequence number, B4 sends fake packets with an outdated timestamp. Inspired by the youtubeUnblock project. Select TCP Timestamp in the Faking strategy dropdown to use it.
  • FIXED: UDP/QUIC traffic stopping to match after some time. B4 now keeps server-to-domain associations active as long as traffic is flowing, preventing the "works at first, then stops" issue.
  • IMPROVED: Rewrite TLS ClientHello payload generation.
