A major new version of Thunderbird, the open source email client, is now available to download.
Thunderbird 78 carries a host of major changes, new features, and usability improvements — though not all are enabled by default.

OpenPGP support in Thunderbird 78 will be available “out of the box” when the Thunderbird 78.2 release arrives, expected in the next few months. Users of the Enigmail Add-on are advised not to upgrade to Thunderbird 78 at this time.
