September 2025 (2025-09) produced strong business value across Thunderbird Android and iOS by delivering documentation improvements, UI enhancements, backend refactors, and CI/QA automation. Notable features include adding the Confistore README to core docs, advancing the Message List with a composable UI and feature flags, and introducing UnifiedAccountId support. A major refactor of LegacyAccount-related DI and backend storage modernized account handling, improved testability and scalability, and reduced coupling. Critical stability and quality fixes were completed, including database migration sequencing, POP3 folder creation stability, and cleanup of code quality issues (Detekt) and authentication wrappers. The month also strengthened CI/CD and developer velocity through Dependabot setups, docs deployment adjustments, and expanded documentation including dev guides and translations, plus Java 21 readiness for Robolectric.
