[1.63.1] - 2026-05-27
- FIXED: Videos and media in some Telegram channels would not load through the MTProto proxy - certain Telegram data centers (notably the one used during file downloads for foreign channels) were unreachable from networks that block direct connections. b4 now uses a rotating list of Cloudflare-proxied fallback domains to reach those data centers transparently, and refreshes the list once an hour from a public source. A new "CF proxy fallback" toggle in Settings → MTProto Proxy lets you turn it off or point at your own list.
- IMPROVED: MTProto proxy feels faster and stays steady when Telegram acts up - b4 keeps a small pool of ready connections to Telegram, so opening a chat or waking the app no longer waits for a fresh handshake. Broken data centers are remembered for a short time so retries fall back instantly instead of stalling, and the error log no longer floods with the same failure - one clear report per minute showing exactly which paths were tried and why each failed.
