We’re back with another progress report as we continue improving K-9 Mail for its transformation to Thunderbird for Android! We spent most of the previous month preparing for a new stable release. In April 2023, we finally published K-9 Mail 6.600.

Last year, our mighty donor base contributed a record-breaking amount in donations to the Thunderbird project. This was a bright, assertive sign that you want to see Thunderbird thriving. Not just in 2023, but decades into the future! 

Last month we reported on the progress we made in turning K-9 Mail into Thunderbird for Android. Since then a month has passed, so it’s time for another detailed update. Let’s dive in!

While K-9 Mail / Thunderbird for Android is developed in the open, following its development on GitHub can be somewhat tedious for a casual observer. So we’re trying something new and summarizing the most notable things that happened in the past month.

“Why does Thunderbird look so old, and why does it take so long to change?” Let’s answer that burning question with some important history, and a look into the future.

In Thunderbird 102.7.0, we will be making some changes to the way we handle OAuth2 authorization with Microsoft accounts, and this may involve some extra work for users currently using Microsoft-hosted accounts through their employer or educational institution.

The path to bringing you a great email experience on Android devices begins with K-9 Mail, which joined the Thunderbird product family earlier this year.

A few short years ago, Thunderbird was on the verge of extinction. But you saved us! Today, we need your help again.

Life gets busy. That’s why the new calendar in Thunderbird Supernova is being designed to look and feel comfortable. It will help you more efficiently sift, sort, and digest all the crucial details of your day.

Thunderbird 102 is here! On behalf of the entire Thunderbird team, I’m thrilled to announce the availability of our major yearly release. Thunderbird 102 is loaded with highly-requested features, and we think you’ll be delighted by them.

The wait for this year’s major new Thunderbird release is almost over!
