Thunderbird's release schedule <u>tracks</u> (but not strictly**) follows the '''ESR''' release schedule of Firefox. You can find links to the schedule (with an ESR column), release notes and other release information, at [[ReleaseRapidRelease/Calendar]].
'** We ship when the release is '''ready''' based on testing and other factors, not on a date certain. So where you see dates take that with a grain of salt - because we will lag dates by some number of days or weeks. Thus you will rarely see us ship per a published date. If you are not seeing the newest version at the [https://www.thunderbird.net/ Thunderbird home page] do not worry, it is because it is just not yet ready for release.
