Adding XKEK Key Domain creation. 
It validates the membership and creates a XKEK Key Domain. XKEK Key Domains can only be created based on memberships for THAT device. A device can only create XKEK Key Domains with memberships issued for itself.

MKEK is also stored with SO encryption. 
A copy of MKEK is also stored but encrypted with SO-PIN. Thus, we always ensure that we have an operative copy of MKEK, either with PIN and/or SO-PIN. If user resets PIN, the MKEK is loaded with SO-PIN and stored with the derived key from new PIN.

Introducing MKEK (Master Key Encryption Key). 
MKEK is used to encrypt all keys in the device, regardless of Key Domains or DKEK. From now on, all keys are encrypted using an AES 256-bit secret key. MKEK is also encrypted and stored based on a derived key from PIN. When user introduces the PIN, the MKEK can be unlocked to load the stored private/secret keys.

User authentication is unlinked from session_pin 
Due to PUK Authentication, user authentication is not linked to having a valid session_pin anymore. In case of enabled PUK Auth, session_pin is used only for unlocking DKEK, but not for granting auth privileges, as they only are granted when PUK Auth succeeds.
