[1.27.0] - 2025-12-27

• ADDED: Discovery Logs panel shows real-time progress during configuration discovery.
• ADDED: Smart CDN detection for 20+ major services (Instagram, Facebook, YouTube, Twitter/X, Telegram, Discord, TikTok, Netflix, Spotify, etc). Discovery now uses full IP ranges instead of single DNS results. View supported services
• ADDED: Automatic DNS bypass for CDN services. When geo-blocked IPs are detected, B4 uses fragmented DNS queries to external resolvers to find working servers.
• IMPROVED: Discovery Logs panel now shows more detailed real-time progress during DPI fingerprinting, DNS checks, and strategy testing.
• IMPROVED: Discovery now uses DNS-over-HTTPS (encrypted DNS via Google/Quad9/Cloudflare) to detect when your ISP returns fake IP addresses for blocked sites. When DNS poisoning is detected, B4 connects directly to the real server to continue testing bypass strategies.
• FIXED: QUIC traffic (used by YouTube, Google, and many modern sites) was ignored when custom UDP ports were configured for any target set. Now UDP port 443 is always monitored regardless of other port settings.
• FIXED: UDP traffic to specific IPs now correctly uses the set that defines both the IP and port filter together, instead of being handled by a different set that only matches the port.
