On behalf of the Thunderbird team, Thunderbird Council, our global community of contributors, and our extended Mozilla family, I am incredibly excited to announce the initial launch of Thunderbird 115 “Supernova” for Linux, macOS, and Windows! 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.
This is a massive release, and modernises this venerable e-mail client considerably. I can’t wait to test it out once it hits the Fedora repositories – I never liked Thunderbird all that much, but Supernova seems like something that suits me a little better, so I’m curious to see if it can pull me away from Geary. If you want to quickly gauge the changes to the user interface, the Thunderbird team made a very handy page for that.
