Thunderbird 78.5 is now available for download. The release is notable for 3 new features, and a number of fixes. Also, there are no known issues in this version of the app.
Thunderbird is my preferred email client of choice. I use this app on every PC and on every operating system I use. It is stable, contains all the features you need, supports add-ons and also comes with a useful RSS reader. I am using Thunderbird for many years and never felt the need to look for an alternative.
Thunderbird 78 doesn't support classic XUL add-ons any more, but includes some of their features natively. E.g. on Windows you can minimize the app to the system tray.
The following changes have been made in versions 78.5
