Current status
With their purchase of Compaq in
2002, HP announced their intention to migrate many of Tru64 UNIX's more innovative features (including its
AdvFS file system, Trucluster, and LSM) to
HP-UX, HP's existing Unix OS. In December
2004, HP announced a change of plan; they would instead use the
Veritas file system and abandon the rest of the Tru64 advanced features. In the process, many of the remaining Tru64 developers were
laid off.

In July 2007, HP stated that they would continue to support Tru64 UNIX until at least 2012, with the next maintenance release, 5.1B-5, planned for the second half of 2008.
