Hostname changed after today's update

[Kelmas]

Today I noticed that my server's hostname changed to the very first one with which cPanel was installed on server. That happened right after regular cPanel update. Half an hour ago cpsrvd and ftpd went down, but successfully restarted.

I am using latest CURRENT.

Can anybody tell me what happened with this update? cPanel's reply would be greatly appreciated.

Just to update. I belive that was because of Kernel's upgrade.
