Ryan, Alex, and Jason get together to talk about the new features and improvements in Thunderbird 115 “Supernova.” But they also share WHY those features were developed, and what’s being worked on right now. Plus, some breaking news about the future of the Thunderbird Project!

Our journey to transform K-9 Mail to Thunderbird for Android involves more than just improving the user interface and adding new features. K-9 Mail is already an important part of the open source ecosystem on Android, and because it lays the foundation for the future of Thunderbird on Android, we believe it’s important to invest in the security health of the software. 

During the next several weeks, you should begin to see your installation of Thunderbird 102 automatically update to Thunderbird 115. Whether you’re upgrading or coming in as a brand new user, now is the perfect time to introduce you to the various elements of the software. This guide will introduce you to the main window of Thunderbird (in its Classic layout and new “Vertical Cards” layout), get you familiar with the terminology, and help you navigate Thunderbird like a pro!

With this year’s version, we’re delivering much more than just another yearly release. Supernova represents a modernized overhaul of the software – both visually and technically – while retaining the familiarity and flexibility you expect from Thunderbird.

Welcome to a brand new feature called “Meet The Team!” In this ongoing series of conversations, I want to introduce you to the humans behind the software you use every day.
