Thunderbird Android client is K-9 Mail reborn, and it's in solid beta

Thunderbird's Android client, which is essentially a rebirth of K-9 Mail, is currently in beta testing and is expected to be officially released by the end of October 2024. The Mozilla Foundation's subsidiary, MZLA, acquired K-9 Mail's source code and has integrated its features into the Thunderbird framework. The beta version, labeled 8.0b2, offers robust functionality, including automatic account setup, message filters, and syncing between mobile and desktop versions. Users are encouraged to test specific features, although the beta will not address existing issues from K-9 Mail. The new Thunderbird app aims to provide a customizable email experience without the distractions of modern email features like AI summaries or integrated chat options. K-9 Mail will continue to exist under its own branding, maintaining its unique identity while sharing the same code base as Thunderbird. The development team is focused on ensuring a smooth transition and a cohesive user experience as they finalize the app.
