It all depends which changes were made, exactly.
We might already have some of them because, when the scenery was in developement (and is still like that, today), GE/VE aerial were still showing the construction in progress, so we had to create those parts without having a reference, but of course we don't know how it compares to real world as it is from this week.
So, it might be helpful first to check the current scenery against the current situation, and have a look at actual pictures. Then we can decide if an update can be made, or we just have to wait for additional data, like updated aerials, for example.
