The 568 prior to v2.5 firmware works completely differently. The whole software architecture has been changed so much that you must think of a 568 and 568.2 prior to v2.5 as being a completely different machine to those at v2.5.

With v2.5, operationally the 568.2mm is a near identical twin of the G6x, or 861>v3.5. Whilst on the surface things look the same, everything changed with v2.5.
