Hi joaoantunescosta,
Adobe team is aware of the openssl EOL details. We are working internally to implement support in Dispatcher for openssl 1.1.x -- Adobe internal ID reference is : DISP-813.
DISP-813 is still being worked on, however, please do bookmark [1] -- this document will be updated upon release.
I could not find the way to subscribe to receive Dispatcher newsletters/updates.
Regards,
Lisa
