[1.38.0] - 2026-02-27

• CHANGED: Vendor Lookup is now optional — the ~6MB device manufacturer database is no longer downloaded at startup. Enable it in Settings > Device Filtering > Vendor Lookup if you want to see device brand names.
• ADDED: TLS Version selector in Discovery — you can now choose which TLS version (Auto / TLS 1.2 / TLS 1.3) to use when probing.
• ADDED: SOCKS5 Proxy — B4 now includes a built-in SOCKS5 proxy server. Apps like browsers, curl, or torrent clients can route traffic through B4 without any system-wide setup. Enable it in Settings > Network Configuration > SOCKS5 Server. Supports optional username/password authentication. (#48, thanks @remmody)
• IMPROVED: Docker support — detects Docker environment and shows docker pull instructions instead of the update button.
• FIXED: Settings page crash (white screen) in container environments — network interface filtering is now container-aware, showing veth and other container interfaces when running inside Docker/MikroTik. (#44, thanks @kakosmakos)
• FIXED: DNS check incorrectly reporting "DNS poisoned" when everything is actually fine. The check could time out before even trying the system resolver, producing a false alarm. Also improved handling of CDN domains (YouTube, Google, etc.) where different resolvers return different but equally valid IPs. (#46)
