Release Information


Catena-X Standards are the foundation for certifying any software component operating in the Catena-X data space. Those standards are the binding reference to obtain a valid certificate.

To make adopting the latest Catena-X standards easier, reference implementations are provided through the Elipse Tractus-X Project. Releases of these reference implementations happen four times a year using a calendar versioning scheme, and include the operating system consisting of core services, enablement services, and KITs.

Please check the Change Log for content, known knowns, and backward compatibility since the calendar versioning scheme readily shows the year and month of release.
