May 1, 2026May 2026 – Summary for trezor-suite mobile: Highlights include feature deliveries, major bug fixes, and performance improvements that deliver business value and improved developer ergonomics. Key features delivered include the AccountAssetsScreen with a token-centric tab layout (Tokens, DeFi, Hidden) plus an Inactive Stellar trustline tab, a collapsible zero-balance tokens section, and FlashList-based rendering for fast, smooth navigation. The DeFi tab surfaces ERC-4626 vault tokens and is supported by updated selectors and internationalization. Refactoring efforts moved getTokens and token categorisation selectors to the suite-common package to enable cross-platform sharing across desktop and native. A design-system upgrade migrated Toast to the new tokens for consistent visuals across platforms. Stability and correctness improvements were implemented across UI rendering and navigation, including fixes to banners UI on the Support screen, a rename of the IIFE parameter to avoid oxc duplicate export, and navigation improvements in TokenAccountDetailHeader. Overall, these changes improved token visibility, reduced maintenance burden, and strengthened performance and reliability.

Apr 1, 2026April 2026 highlights for trezor/trezor-suite: delivered substantial UI polish, DS-aligned refactors, and foundational work to support scalable UX across the suite. Key bug fixes included reconnect state handling after device wipe, Skia canvas color updates on theme changes, WalletBackupSheet footer overlap fix, and improvements to the swipeable walkthrough and Switch color alignment. Design-system migrations and component refactors delivered a more consistent look and feel: AnimatedCard, Badge, and Radio DS updates, plus CheckBox and RoundedIcon token alignments. Storybook infrastructure was modernized with Skia web storybook setup and new stories for BottomSheetModal, Toast, AlertSheet, and Link, plus mobile storybook resilience after Vite 8. Address formatting was modernized with a shared AddressFormatter, chunked formatting across the app, and a centralized addressDisplayType in walletSettings, plus a spacing toggle for advanced settings. XPUB button visibility logic was clarified and tested, hiding the button for address-based accounts and validating with tests. These contributions collectively reduce UI debt, improve developer velocity, and deliver a more scalable, DS-compliant user experience with measurable business value.
