Announcing the release of the kernel-ml-6.3.7-1.el7.elrepo package set

The upstream changelog:
https://www.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.7
I have perhaps the world's only mythtv system running under kernel-ml.
It has been going well until this update, after which the frontend was
unable contact the backend, and attempts to kill tha backend also failed.
It's ok again after switching back to 6.3.6. I would prefer to stay
there, but could do more tests if I knew what might help.

Hi John,
As far as I can tell, the kernel config file did not change when going
from 6.3.6 to 6.3.7. I wonder what else affected mythtv. This needs
some deeper investigation.
Akemi
Hi Akemi, tanks for the response. There were some python3 updates too,
but I'm seeing no problems with them after going back to 6.3.6
I thought there might be something here, but again it's ok with 6.3.6
