Mar 1, 2026March 2026 (thunderbird-android) delivered a cohesive Message List overhaul and design-system integration that improves user experience, maintainability, and reliability. Key improvements include a unified, configuration-driven MessageItem with enhanced sender/address rendering, a more expressive and accessible UI surface, and robust state-machine instrumentation for easier debugging and performance tuning. The work also expanded design-system capabilities with new badges, icons, and avatar components, strengthened accessibility and testing, and added color/config options for read-state visualization. Overall, these changes enable faster UI iteration, richer messaging UI, and more predictable production behavior while reducing maintenance burden.

Jan 1, 2026January 2026 monthly summary for thunderbird/thunderbird-android: Focused on stabilizing and modernizing the Message List feature set, strengthening testability, and enabling more robust configuration and UI behavior. Implemented a complete MVI/state machine core for the Message List with side effects for loading preferences and handling swipe actions, enabling deterministic state transitions and easier future enhancements. Refactored the Message List API surface: renamed MessageListFragment to AbstractMessageListFragment, extracted LegacyMessageListFragment, and introduced a Factory pattern with feature flags to support runtime toggling between legacy and new flows. Added sorting and preferences capabilities through dedicated use cases (GetSortTypes, GetDefaultSortType) and state-side effects to load saved sort types, plus DI improvements (Koin) to allow parameterized list creation. Enhanced view model and state: added folderId argument to the new Message List view model and loaded folder information into MessageListState. UI/Design-system improvements include a ClickableSurface atom and aligning swipe actions with view model state. Quality and reliability gains include unit tests for MessageListStateMachine and stabilizing Robolectric tests by disabling the C2 compiler. A critical OAuth configuration issue was fixed by adding the missing scope to the MS config to resolve SMTP auth failures for university accounts. Business value: faster, safer feature delivery; improved UX with richer sort/folder capabilities; and more reliable test infrastructure.”,
