On 13 Jan 2015 IBM launched a new z Systems platform, IBM z13.
Is Endevor v15.1 compatible with IBM’s z13 platform?
Because Endevor v15.1 is no longer supported since March 31, 2015, it hasn’t been tested with the new z13 platform. CA cannot guarantee that v15.1 is fully compatible, but because Endevor is more dependent on the OS then on the hardware, chances are that it will work.
Another aspect to be taken into consideration is that CA will not be able to provide any fixes in case of a problem related to the new hardware.
Z13 has been however certified with all other supported releases of Endevor (v16.0, v17.0, v18.0) https://support.ca.com/phpdocs/0/MSPSaccount/COMPAT/IBM_hardware.HTML
Endevor v15.1 has been certified with z/OS 1.12, 1.13 and 2.1
