Nov 1, 2025November 2025 performance summary for SatoshiPortal/bullbitcoin-mobile: Implemented robust Electrum server URL handling to improve reliability and user experience. Refactoring separated host and port, added port range validation, and tightened UI validation to enforce a host:port format without protocols. Fixed a UI/logic bug where TCP connections could display as SSL after adding a custom server, eliminating a confusing indicator for users.
