expat with carta de soggiorno (illimitata)

I an non EU but I am resident of Italy (carta de soggiorno illimitata) I would like to ask if its still possible to enter Italy again even though I stayed longer in Philippines for almost 2 years.
Because some say there's a new law stating if you're resident of italy (unlimited) you need to go back not more than 1 year to Italy. I need some advise regarding this matter. I have flight next week and I need to know if its hinder me to enter Italy again. thanks
