For VSE installations, non-Windows platforms, and OEM customers, the new Engine will be available from the Security Updates page and SDK as an Elective update during the end of June 2021.

The auto-update push to VSE, ENSL, ENSM, and other products consuming V2 and MED DATs is expected towards the end of July 2021.
