Ansa reports on the matter

That's similar to what was reported last week here. It just means that the earlier conforming by Di Maio and Salvini was very much just to agree with what Conte initially proposed.
This is rather strange because it was reported on Friday that the cut to 2.04% may not be enough for the European Commission to accept it. Either way, if Conte believes that this will get through, then it likely will.
It's about time we put this behind us anyway, and as mentioned before it doesn't really matter when 2019 comes because the proposal here is built on unrealistic growth forecasts (Italy GDP growth of 1.5% y/y next year). The real issue and debate to come is that the debt-to-GDP ratio will still balloon up and when measured to actual growth, the budget deficit will probably be something like 2.8% or 3.0% unless the Italian economy miraculously recovers.
But that will be something for markets to worry next year instead.
