The kernel level for 7.6 is kernel-3.10.0-957.el7. Furthermore the kernel-alt introduced with RHEL 7.5, has been updated to 7.6-alt is kernel-4.14.0-115.el7a. This release is mainly a bug fix release. From a feature perpspective two larger items made it into this relase. First finally AES-GCM is accelerated from openssl on z14. And second the gdb can now interpret z14 instructions.
