The Thunderbird email client has introduced a new logo after nearly 20 years, designed by Jon Hicks, the creator of the original Firefox and Thunderbird logos. The new logo aims to honor the project's history while representing its modernization and revitalization. The logo will be integrated into Thunderbird 115, codenamed 'Supernova', this summer, along with a redesign of the website and branding on social channels. The new logo has received largely positive feedback from the community.
