Latest release

Upcoming releases

Thunderbird does not have a solid schedule of dates, that version X will happen on mm/dd/yyyy. We track but does not strictly follow** the ESR release schedule of Firefox. See the ESR column of RapidRelease/Calendar.

  • We typically release 1-3 weeks after Firefox, but it is can be more or it can be less because we ship when code is ready and tested, not on a specific date certain. In other words dates cannot be predicted and you should take any dates you see with a grain of salt. If you do not see the "newest" version at the Thunderbird home page, do not worry, it is just not yet ready. Regarding specific features and fixes, these happen as volunteers have time to work on them and fix them. There are no schedules that can be communicated to users. If you want new features sooner than normal, please help us test and code, or use the beta mentioned above.
