Differences between 6.7 and 7.0

[s7r <s7r@sky-ip.org>]

Hi
What are the main and most important differences between Knoppix 6.7 
and 7.0?
Does version 7.0 support the persistent changes feature with AES 
encrypted data file where changes and saved files are kept? Will it work 
the same ? What other changes.

Thanks
