No keys has been changed, not even in the core. So here's my quick inspection.

Surprising eh?
>System stability has been improved via packages
>Blu Ray seems to be pushing for a new update [Judging from files names]
*Update* Its a firmware for the new drive models that an update for the 0xA

>PlayStation Store menu transition/Loading time has improved
OFW can be upgraded (meaning that security is not the new update)
>No syscon updates
>No key changes
>No Passphrase change
This is most likely a upgrade for the console not for the security as there was no keys changed
I'll keep you guys updated.
*That seems to be pretty much it..
