Sometimes it's REALLY tough to keep a secret. But now that the secret's out...
Our new logo is designed by @jonhicks, the creator of the original Firefox and Thunderbird logos. It will make its way to you when Thunderbird 115 launches this summer!
(For background: One of Thunderbird's core principles is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services that can’t communicate with each other. Our upcoming marketing efforts will really lean into this, and we want a long-term hashtag to accompany it.)
