v1.6.2

BREAKING

This release is breaking if nil checks were done on the nextroute.SolutionStop interface (as it is now becoming a struct for performance reasons). It is recommended to use .IsZero() check instead from now on.

I.e., the following code:

var stop nextroute.SolutionStop = nil
// ...
if stop == nil {
  // ...
}

becomes:

var stop nextroute.SolutionStop
// ...
if stop.IsZero() {
  // ...
}
