[1.50.2] - 2026-05-02

• ADDED: Share MTProto proxy connection - new "Share connection link" button in Settings > MTProto Proxy. Opens a dialog with a tg:// connection link, a QR code (scan with your phone camera to add the proxy to Telegram), and Copy / Open in Telegram / Share buttons.
• FIXED: Service crashed at startup on routers without ipset - "Enable Packet Duplication" could prevent b4 from starting on routers where ipset is not installed (some Keenetic / Merlin setups). b4 now logs a warning and keeps running. For full-connection duplication, install ipset (Keenetic / Entware: opkg install ipset).
• FIXED: "Update" button in Web UI didn't actually update b4 - on some setups clicking "Update" did nothing and the version stayed the same after restart.
