This message is related to today's announcement on the Thunderbird blog:

Two popular technologies exist that add support for end-to-end
encryption and digital signatures to email. Thunderbird has been
offering built-in support for S/MIME for many years, and will continue
to do so.

The Enigmail Add-on has made it possible to use Thunderbird with
external GnuPG software for OpenPGP messaging.

Because Thunderbird 78 will no longer support classic Add-ons, the
current Thunderbird 68.x branch (maintained until Fall 2020) will be the
last that can be used with Enigmail.

As a replacement, the Thunderbird team intends to develop integrated
OpenPGP messaging for the next major version of Thunderbird, which will
be released in summer 2020 (likely version 78).

We are happy that Patrick Brunschwig, who has been developing and
maintaining the Enigmail Add-on for many years, has offered to assist
the Thunderbird development team.

Many details need to be considered for this initiative.

Please have a look at the following article which describes the approach
we'd like to take:
