Dec 1, 2025December 2025 focused on UX improvements, reliability hardening, and security/perimeter protections across trezor-firmware. Key deliverables included bootloader UI enhancements that show build version numbers and support disabling progress animations for faster boot, with improved warning icon alignment. Reliability improvements addressed Tropic reset via refined chip select handling and retry sequencing, reducing initialization failures on reset. Telemetry and power management upgrades added battery temperature telemetry and improved MPU configuration to boost responsiveness and power efficiency. Security and production protections were strengthened with backup RAM access restrictions and production protection measures to prevent data erasure, plus Secure Monitor downgrade protection with monotonic versioning to block insecure rollbacks. In addition, production date exposure to MicroPython was implemented to support metadata visibility. Together these contributions increased customer trust, decreased field-support incidents, and enabled better diagnostics and security posture.
