AT upgrades and support

The AT Maintenance Program bundled with the currently available AT 2.0 client application is designed to support upgrading an AT database from previous AT versions.

With the release of AT 2.0, the AT project team no longer works on new development, but does build maintenance releases when necessary. While the team will continue to support previous production versions of the AT, we encourage users to upgrade to the latest version, AT 2.0.14, and enjoy its improved functionality.

Please feel free to contact the AT team at if you have any questions or concerns.
