Just spoke with Customer Care rep. (12/10/24)

There will be no QBDT 2025 release.  QBDT 2024 will get updated indefinitely.

For DT payroll clients, 2022 will be shut down in May 2025.

For DT payroll clients, 2023 will be shut down in May 2026.

QBDT 2024 will be the only version available to process payroll after May 2026.

This all appears to be part of the bigger plan to migrate everyone to the Online platform.
