Sep 1, 2025September 2025: Localization and quality-assurance focused month for trezor-suite. Key features delivered include suite-native language management with a UI for language selection, and the integration of CrowdIn translations tooling into CI pipelines, enabling automated localization workflows. Substantial E2E testing improvements were introduced, including reusable fixtures, accurate test IDs, test graph toggle, and Redux state launch arguments, alongside CI/test stability fixes across iOS/Android. Developer tooling improvements were also shipped with Rozenite debugger plugins to streamline development. These efforts improved localization reliability, reduced manual translation overhead, and increased release confidence through more robust end-to-end testing and performance optimizations.

Apr 1, 2025April 2025 — trezor/trezor-suite focused on stabilizing onboarding, improving backup UX, and enhancing telemetry to guide product decisions. Key features delivered include wallet backup flow enhancements (backup instructions step and backup creation), accordion atoms refactor for cleaner architecture, continued Trezor image handling improvements, and onboarding-related enhancements such as skipping the device tutorial action and reporting device mode on connection. Analytics were extended to capture device onboarding events, supporting data-driven iteration, and the release was prepared with a version bump to 25.4.3. Major bugs fixed include stabilizing the iOS native build (revert of sharp build), disabling RTL support, fixes to token send, skipping firmware update screen for latest firmware, onboarding UI copy improvements, and broader onboarding error handling and recovery improvements, along with tests and Detox path adjustments. These fixes reduce onboarding friction, improve reliability, and decrease support effort. Overall impact and accomplishments: improved stability across iOS, more reliable wallet backup and onboarding flows, stronger telemetry for product decisions, and better release readiness. This combination of fixes and refinements increases user confidence, accelerates onboarding, and lowers operational risk. Technologies/skills demonstrated: React Native / suite-native development, iOS build processes, UI/UX polish, robust onboarding and error handling patterns, analytics integration, test hygiene and redaction in tests, and targeted code refactors to improve maintainability.
