thunderbird (1:78.3.1-1) unstable; urgency=medium

  The Thunderbird ESR series starting with version 78.x has finally dropped the
  support for legacy Add-ons and also for legacy WebExtension Add-ons.
  By this some packaged Add-ons within Debian, but also some external installed
  Add-ons might not working any more!

  The very popular Add-on Enigmail, which was providing OpenPGP support within
  the Thunderbird application, isn't getting further development as an external
  Add-on due a consequence of the changed Add-on API.
  Instead Thunderbird now has Built-In OpenPGP support since version 78.0.
  The latest version of the Enigmail Add-on (>= 2.2) will provide an migration
  wizard which helps to migrate the existing OpenPGP keys into Thunderbird.

  Please have a look for further information about Enigmail on the project
  homepage and the Add-on website.
