Sep 1, 2025September 2025 delivered a strong set of core firmware enhancements focused on security, reliability, and developer productivity. Key security/verification work includes a BootloaderV2 fingerprint feature and fingerprint tooling improvements to surface the secmon fingerprint in prodtest. Core reliability and performance were advanced with a new lock_manager component to manage synchronization and asynchronous notifications, plus subsequent optimization and a UI repaint fix after suspend. Build tooling was modernized by migrating to uv/pyproject.toml and dropping Poetry, with wide coverage across core/python/tools to uv, reducing build times and improving consistency. Developer experience and quality were boosted through code style and tooling updates (pyright 1.1.404 alignment, Black/flake8), emulator/test capabilities (suspend support and suspend logging), and UI/backlight UX improvements (explicit repaint and backlight fading during background work). Minor doc/packaging cleanup complemented these changes, improving maintenance and onboarding for new contributors.

May 1, 2025May 2025: Reworked the definitions data access path with a generalized 'definitions' base URL, updated paths, and consolidated documentation; improved CLI code organization by relocating a related function. Implemented Unicode normalization from NFKC to NFC for stable multilingual text and added font support for the 'º' character in translations. Enhanced code hygiene by moving the impractical network_from_address_n function out of the Ethereum module to improve module boundaries. These changes reduce API confusion, strengthen internationalization reliability, and streamline future definitions-related work.
