It's new from the point that art 370 will in a way has been agreed and there is no going back to that order. Even Pakistan knows it.Cease fire agreement isn't new if you are trying to look it like a change about Kashmir. Before making such a claim like a naive, check history.
Kashmir status remains disputed as UN resolutions and Indian occupation couldn't change it.
India is very happy for an ceasefire as well. It's soldiers (also Pakistanis) can get some well deserved cool off period.
Pakistan with all its Nazi calling , not accepting anything till art 370 is restored etc has made an bit of an climbdown. It might have it own strategic reason (like its own loan repayment, deficits etc) to which Indian leadership have agreed pretty soon. But this instance is not comparable to past history. As of now. Whether it will become like past years is to wait and watch
