Synergex will end support for Synergy/DE 12.1 on April 1, 2026. After this date, version 12.1 will no longer receive fixes or security updates.

If you’re using Synergy/DE 12.1 or an earlier version, we strongly recommend updating to the current long-term support (LTS) release, Synergy/DE 12.3, which will be supported through at least March 2028.

Per our Release Strategy, LTS versions are supported for a minimum of four years (four years after their release OR one year after the next LTS version ships, whichever is later). Version 12.1 was released April 1, 2022, and 12.3 launched on March 18, 2024, establishing April 1, 2026, as end-of-support for 12.1.

If you have any questions or need assistance upgrading, please contact your account manager or Developer Support at support@synergex.com.
