"Under the modification proposed herein, SpaceX would reduce the number of satellites and relocate the original shell of 1,600 satellites authorized to operate at 1,150 km to create a new lower shell of 1,584 satellites operating at 550 km"
This shell will also now use 24 orbital planes instead of an originally planned 32. (per a table in the technical information pdf).
The total number of satellites in the constellation goes from 4,425 to 4,409.
