Jan 1, 2026January 2026 (2026-01) focused on stabilizing and modernizing the Connect flow in trezor-suite, with a major refactor of the Connect module to CoreInModule, packaging simplifications, and removal of legacy state and popup constructs. This work reduced surface area for bugs and improved maintainability, while preserving or enhancing user flows. Key improvements include architectural cleanup (PopupManager revamp, removal of deprecated API surfaces), direct CoreInModule usage, and consolidated dynamic wiring. In parallel, suite-sync stability improvements and targeted test fixes increased release reliability. The month also delivered critical E2E/test fixes (hash redirection handling and backup-test reliability) and improved device-state handling during syncing. Representative commits and work items below demonstrate the breadth of changes across core refactor, testing, and cleanup activities.
