OpenHAB 2 items sync with

Hello all,
I’ve moved to OH2 my OH1 configuration, all works pretty well but what I’ve noticed is that all of my items are synchronized with while in OH1 it was limited by myopenhab.persist configuration

Does something changed in this matter and in OH2 all items are synced or I messed something up? I couldn’t find any info about it.

let me know please.
