libptpmgmt 2.0 with Clock Manager Released
October 22, 2025 by Dru Lavigne
Erez Geva, Project Manager for the libptpmgmt Project, has announced the release of libptpmgmt 2.0:
With great pleasure I wish to update you on a new release of libptpmgmt. The new version 2.0 includes the new Intel Clock manager sub-project.
The libptpmgmt library is not ABI backward compatible with libptpmgmt 1.x. Of course most of the API is the same. Developers using libptpmgmt can easily update to libptpmgmt 2.0. The Intel Clock manager is built by default, but can be skipped using a configuration flag.
Several resources are available to learn more about this release and the new Clock Manager:
