[1.33.2] - 2026-02-07

• 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 Instead of using a low TTL or wrong sequence number, B4 sends fake packets with an outdated timestamp.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.

What's Changed

• feat(tcp): add TCP Timestamp faking strategy and related configurations by @DanielLavrushin in #23
