The wait is over! Download and learn how to help us test the Thunderbird for Android beta for the upcoming regular release.
The Thunderbird for Android beta is out and we’re asking our community to help us test it. Beta testing helps us find critical bugs and rough edges that we can polish in the next few weeks. The more people who test the beta and ensure everything in the testing checklist works correctly, the better!
Anyone can be a beta tester! Whether you’re an experienced beta tester or you’ve never tested a beta image before, we want to make it easy for you. We are grateful for your time and energy, so we aim to make testing quick, efficient, and hopefully fun!!
The release plan is as follows, and we hope to stick to this timeline unless we encounter any major hurdles:
September 30 – First beta for Thunderbird for Android
Third week of October – first release candidate
Fourth week of October – Thunderbird for Android release
The Fennec F-Droid build isn't maintained by Mozilla, but by someone else. They link to Mozilla for donations and source code, but the issue tracker for Fennec on F-Droid links to their own repo.
K-9 Mail on F-Droid is maintained by the K9-team, which works for MZLA/Thunderbird. Thus I'd guess it shouldn't take to much work adding Thunderbird to F-Droid.
from the page it looks like they're working on getting the beta in fdroid though, so here's hoping.
